Re: video convert

Hi,

First we need to see if the ffmpeg is outputting an error. This is very important, because we don't know what are the missing parameters if there are any.

1. Make sure the directory is CHMOD to 0755 or 755 or 0777 or 777 depending on your server settings.

2. Let's ignore the flvtool2 function first, and work on the ffmpeg diagnostic before anything else.

3. Copy codes below and run it on your server.

<?php
## written by PoorBoy from veedeoo.com
## or veedeoo Junior Poster in Training from daniweb.com
## define ffmpeg location

$ffmpeg_loc = "/usr/bin/ffmpeg";
## define location of video to be converted to flv and some other settings
$input = "upload_v/veer.avi";
$a_freq = "44100";
$a_br = "64";
$v_br = "600";
$v_fr = "30";
$out_flv = "upload_v/veer.flv";
$encodeVideo = ($ffmpeg_loc." -i ".$input." -ar ".$a_feq." -ab ".$a_br."k -b ".$v_br."k -r ".$v_fr." -ac 2 -f flv -y -s 640x420 ".$out_flv);

## now we need to fire up the $encodeVideo through exec command..
## while the ffmpeg is being executed, we need to trap any errors it may have.
exec($encodeVideo." 2>&1", $res, $err);
$errorlog = '' ;
foreach ($res as $errodata) {
$erorlog .= $errodata."<br>" ;
}
## you can echo the error if you want, by uncommenting the code below
//echo $errorlog;

## or you can write it as an html page for you view on the browser.
$errordatapath = "upload_v/erroroutput.html" ;
$file = fopen($errordatapath, "w") ;
fwrite($file, $erorlog) ;

Re: Cannot modify header information - headers already sent by

Ardav is right, if javascript is off then user is trapped..

you can still use the same codes as you were, but you will have to rotate your codes.. like this

Remove the php closing tag below line 47, and then rearrange your codes as shown below.

// Get the data:

$row = mysqli_fetch_array ($r, MYSQLI_NUM);
$_SESSION['email'] = $_POST['email'];
//wait at least 1 second and then fire the header location
sleep(1); 
header('Location:welcome.php');

The problem with the above is that if 1 second is not enough time to wait for the $row result to comeback, then it has to be increased to at least 2. Users are impatient to wait even a fraction of a second in front of a blank page. While the javascript, allows the browser to take over after the $row is returned by the mysql server. Once the browser is on the welcome.php, the server takes over again to parse the content.

This is common problem if you are hosted by c__tex or some other hosting servers having the same setting as C__tex or h__tV where the mysql server is slow to respond, but the server where the PHP codes resides already parse your header location command. Often times, in a hosting like this you would get something like this "mysql server has gone away", or something in this regard. Believe me, I spent a good months exchanging nasty messages with c__tex support, but to no avail. So, I came out with the javascript …

Re: add facebook connect functionality

//uses the PHP SDK.  Download from https://github.com/facebook/php-sdk
require 'facebook.php';

$facebook = new Facebook(array(

));

$userId = $facebook->getUser();

      window.fbAsyncInit = function() {
        FB.init({
          appId      : '<?= YOUR_APP_ID ?>',
          status     : true, 
          cookie     : true,

Re: print

Hi,

Thanks for clearing that out. :) I was only joking of course. :).

To print the current page where the browser is on, we need javascript function something like window.print()

So, my example would be like this..

<?php

echo "Hello I am written by way of php echo function, but I will definitely get printed by way of javascript function";

?>
<!-- we do it by form -->
<form>
<input type="button" value="Print Me" onClick="window.print()" />
</form>
<br/>
<!-- or do it by text link -->
<a href="#" onClick="window.print()"/>Print Me</a><br/>

Re: how to display video or audio element using php script?

and you expect this echo "<a target='_blank' href=$dir>$name</a> <br>"; to deliver your audience the video or the audio?

Shouldn't it be like this?
echo '<a target="_blank" href="'.$dir.$name.'">'.$name.'</a> <br>';

How about the file extension? Is it included in your $name? If not, it should be wiser to find the extension of the file $dir.$name first and then assign the extension to $ext. so that the codes will be
echo '<a target="_blank" href="'.$dir.$name.$ext.'">'.$name.'</a> <br>';

I am assuming here that $dir = "someDirectory/"; and $name = "somefile.whateverext";

If you want the video to play on the page, then you should have a way of delivering the $name.$ext to the next page, so that it will be loaded on the player. The above codes, just gives the browser to download the file and not to play it.

There are so many ways in passing the video info. to the play page.. In fact, the most common is either by $_GET, or by session like in
$_SESSION = $name.$ext; whatever you choose, it has to have the $dir.$name.$ext because player can be different for audio and video.

Re: The meaning of " <= " in php

@nguoixanh,

Don't be confused with it. It is just a comparison operator. What the thing meant is that IF total_pages is LESS THAN or EQUAL to scroll_pages, THEN do something.

What you should have paid attention closely, is on how the script come up with this..
$this->$total_pages and $this -> scroll_pages, because that's the one that will prime yourself in OOP.

Something like this..
$this -> scroll_pages = $scroll_pages;
$this -> total_pages = $total_pages;

Without using the class pages, you can also practice using those operators by just practicing in something simple like..

<?php
$scroll_pages = 5;
$total_pages = 10;

## let's practice something similar to the page class above.
## normally in class you would start as $whatever = new page(); $whatever->page_link();, and the function page_link will get executed or evaluated..

if($total_pages <= $scroll_pages){

echo "Total pages is less than or equal to Scroll pages";
}

else{

## if you run this script, it should print Total pages is greater than Scroll pages on your screen

echo "Total pages is greater than Scroll pages";

}
?>

Re: How to add a photogallery with thumbnails?

Hi,

Wow, how old is your server? :). I am definitely sure, it must be older than me, because my dad was writing program in CGI because that's the only language of choice, before I was born :).

Anyways, if that is what you want.. you can use microsoft frontpage. The reason I am recommending this because it has an option for you to make thumbnails of your bigger photos or images.

Re: creating a website using phpcake or write my own ??

I spent a little more than 6 months on learning how to bake the Cake, because it was the hype in our family dining table. Four of my older brothers are all programmers working for the big Companies here in California the G, PP, and the eB. Then all of the sudden that mood had changed and everyone are going for the Zend framework. I tried to learned it, but it is taking most of my time just to get familiarize with the framework's lingo.

After learning some of the few tricks, I came to realize that what I have learned does not even apply to what I am trying to make. It is just like putting a piece of pitted olive in a 10 quart can. Big framework and small application don't matched pretty well. Learning frameworks will help a lot if you will be applying for jobs, and most importantly having the Zend certificate can give a better chance of being hired for the job.

After many sleepless nights learning these frameworks, I finally settled in for much simpler approach. I am currently using NetBeans IDE an integrated tools for PHP with smarty plugins, and a reliable msyql class. That's should suffice to whatever what I have to invent script wise :).

Re: my site hacked by pakcyberpyrates

@rajan,

Make sure all of your form processors throughout your site is either $_POST or $_GET, and NOT $_REQUEST for any uploader script. You may want to check and make sure allow_url_include is not set to ON. If you set this to ON, because of any scrapers or any parser script requiring it, use cURL then feed the cURL output to the parser.

I really don't want to show example how its done, because it will give idea to curious people on hacking, and the next thing we know we ended up with 100 more hacking wannabees.

The second probable cause might have been coming from the sites you have visited lately and the use of filezilla ftp program. The deal here is the trojan grabs Application Data\FileZilla\sitemanager.xml file and then use whatever ftp credentials can be found in there to access your site. I helped many people 2 years ago who were victimized by this method.

The third and the most common mistakes is the form input filtering. Most upload script were written and deployed unguarded..for example, some of them don't even have any file extensions filtering mechanism, which allows the uploader to upload any files they want that includes php files that can be executed once the suspected hackers knows the location of uploaded files. Hackers can easily browse your form source codes, and then attempt to do a few remote uploads from their server.. they would try to upload php files …

And this one will only output one

Re: Evaluate Formula from a string

Let me just add, that in case the $x, $y, and $z are given the way they are laid out on your codes above, then this will calculate the same result. The only time you will have to probably assign a new value for $x, $y, and $z in
$newformula = str_replace($x, $x, $formula);
$newformula1 = str_replace($y, $y, $newformula);
$newformula2 = str_replace($z, $z, $newformula);

if the values for $x, $y, and $z are not assigned, or there will be new value or values that the script needs to be included. Otherwise the codes below will suffice.

<?php
	$x = .0832;
$y = .0673;
$z = 1.5;

Re: Evaluate Formula from a string

Hi,

Just my humble opinion..If you want your formula to do the calculation, then don't treat them as a text string.. For example $x = 1; echo $x, will give us 1 which is treated as integer rather a text string, and so forth.

Try this

<?php
	$x = .0832;
$y = .0673;
$z = 1.5;

$formula = $x -(($x-$y)*($z-1.0));

        $newformula = str_replace($x, $x, $formula);
	$newformula = str_replace($y, $y, $newformula);
	$newformula = str_replace($z, $z, $newformula);
	
	echo '</br>'.$newformula;
?>

The above codes should give you a result of 0.07525 if that's the answer you want to be calculated. Or do you want the derivatives of the $newformula? e.g. x² + 2x − 8 ->2x + 2 = 0 or => (x + 4)(x − 2).

Re: screenshot of any webpage using php

@ amitgmail,

Yes, you can save the thumbs if you want. There are two options in doing this.

1. You can use imagecreatefromjpeg. This method requires the allow_url_fopen must be ON in your php.ini file. The consequences of using this method is somewhat greater exposure to security holes if not use properly. I will not discuss the security vulnerability here about the url_fopen, because it will fill up this page. You can search url_fopen. This topic has been discussed in great detail in php security consortium. Anyone with proper knowledge of how to take advantage of this vulnerability can easily transfer malicious file on your server. Meaning, once it is transferred they can execute their codes.

Here is how you will save the screenshots using the first option above..Let's use my example codes provided on the previous page of this thread.

}

We can also assign them into variables as you wish, as shown in my example below..

$name = $items->value[2];
$email = $items->value[4];

You may want to consider setting up some check points to see if the xml file does exist, like so

if (file_exists('test.xml')) {
$xml = @simplexml_load_file($xml);

Re: Templating again: Loops

If my guess is right, we can use a Dot notation array access class. In addition, an array can be nested within an array deeper than what we can normally do without the dot notation class.

Then we can implement the loop the way twig and smarty implement their loops.

Re: Not able to upload files on server but in local

Hi,

Copy codes and read instructions below.. For security reason, DO NOT post the url of your AnyNameYouWant.php

<?php phpinfo(); ?>

copy,paste on notepad, save as AnyNameYouWant.php, upload to your server, direct your browser to this file. e.g. YourDomainDotCom/AnyNameYouWant.php .

After performing the above recommendations, please post the following values of what you see on your YourDomainDotCom/AnyNameYouWant.php.

I need values for the following from your server configurations.

PHP Version anything below 5.2.7 is less problematic. Due to some issues not related to your questions, but will post my answer if addressed.

Server API CGI, FAST CGI or Apache module?

max_execution_time normally, a new hosting account gets about 30, and you need more than that. At least 1000 to 2000 is ideal.

post_max_size The value of this must be equal to the value of upload_max_filesize. In some server settings this value is preset to about 8M. Again 8M is not enough to accept file uploads for much bigger files.

upload_max_filesize The values here must be more than what you are trying to upload. Default server settings as handed to you by your hosting provider is set to 2M or 2MB. Depending on your server setting CGI or Apache module, we can do some adjustments to meet your needs.

Re: video implimantation in website

Hi,

I can show you how to do a pseudostreaming for flv videos, and a quick start on MP4/h264 just like the one you see on youtube. However, before I can do that you need to change your player preferences . It has to be jwplayer or flowplayer. On top of the player change, you will need to have flvtool2,ffmpeg, and ffmpeg php installed on your server, OR at least have the means to inject metadata on your videos prior to uploading them in your server.

The quick start for the mp4/h264 videos requires an mp4box installed on your server, and the ffmpeg installation must be compiled with the x264 if you are to encode videos in the server. Otherwise, some GUI video encoders and MOOV ATOM relocators will just do as fine as what I have already mentioned above.

I wrote many scripts for video applications, including bandwidth calculators, remote server transfer to and fro, video server load balancer, and remote server streamers by way of HTTP and RTMP video streaming, and the script that went flop flv VOD..that did not make the cut at all ;).

Re: user log in error

Can you please confirm if the password in your database was posted as md5 hash? You can check it on your MyPhpAdmin..locate the member in questions, and then check the password column. In the password column the password should look something like this 9cafeef08db2dd477098a0293e71f90a, or you can check the form processor on your registration page if the password made by the new user is being posted as md5..for example $password = md5($_POST).

If it was not or your registration form processor does not convert the password to md5, then do what prvnkmr194 is suggesting.

Re: PHP listbox from database

Hi,

Just my guess, by glancing at your codes, aren't you supposed to post this name="app" to have some value for your second query?

Something like this

$whatever = $_POST;

and then on your query, it can be like this
$query="select * from $stuff where appname='$whatever'";

Notice I did not use $name, because you already used it on the earlier part of your script. I am afraid, I might just caused a naming collision. :).

Re: PHP Tutorial Part One: Getting Started with PHP

Just a humble suggestion...for a tutorial such as this..The coding standard must follow the Zend Framework PHP Coding Standard. By doing so, the new learners or readers of the tutorial will be exposed to the proper coding standard and convention.

Please allow me quote one of the best quote I have read, when I was active in Zend community. Here I quote

One of the joys of PHP is that it’s very flexible, and that flexibility extends to how you layout your code. As long as you observe the basic rules, such as terminating each command with a semicolon and wrapping code blocks in curly braces, you can format your code however you like, because PHP ignores whitespace inside code blocks. As a result, many different styles of coding have sprung up. There’s nothing inherently right or wrong with any of them. As long as the code is readable—and works—that’s all that really matters.

But then again, there is a solid opposition to opening your php codes in shorthand..the coding style conventions states that

1. Always use the full opening PHP tag (<?php).
2. Omit the closing PHP tag (?>) in files that contain only PHP code. The closing PHP tag is optional, provided nothing else (e.g., HTML) comes after the PHP code. Leaving out the closing tag has the advantage of preventing unwanted whitespace triggering the “headers already sent” error when using includes(http://docs.php.net/manual/en/language.basic-syntax.instructionseparation.php).
3. Indent code four spaces (I always followed this, but …

Re: user log in error

Hi,

Without any intend of disrespect, session_register is deprecated in php version 5.3.x . Plus it is a dangerous thing to do security wise. http://php.net/manual/en/function.session-register.php

Just in case some people are trap into using this php function, because their sessions are stack within an array.. The simple solution is put the sessions in an array as shown below.
$session_inarray = array($user,$info1,$info2, $info3, $some_moreinfo_here);
## assign the above into session
$_SESSION = $session_inarray;
## to get the values in the session onto the other page, we simply do it
$user = $_SESSION[0]; $info1 = $_SESSION[1];...and so forth.

My post may not directly answer your questions, but it addressed one of the most critical issues on your script.

Re: Previous Next Script for MySQL- PHP

Im not sure if it matters since it would appear to the browser like it was originally their, but I have added this script as an include on this page below another include I would like to remove once this script works.

oh no...:), the script responsible for showing your content must be the same script counting the row and doing the pagination. Try looking at the script responsible for showing your content on your page. You can probably insert the pagination codes there. I am pretty sure it will be a lot easier than including a new one to do the pagination for the other.

Re: Previous Next Script for MySQL- PHP

I think you are missing the numerical rows..

Try this

## we need to get the count of affected rows by your query
## putting a LIMIT will obviously limit your result and may not have anything left ## for the script to paginate.
$sql = "SELECT COUNT(*) from inthemix WHERE inthemixid = $inthemixid ORDER by inthemixid desc";
$query = mysql_query($sql,$db);
## we get the result count
$total_results = mysql_num_row($query);
## the numerical rows
$num_rows = $total_results[0];
## define the  number of items on the page
$limit = "4"; //limit of archived results per page.
## calculate how many pages the script has to make
$total_pages = ceil($num_rows / $limit); //total number of pages

Try it first..the rule of thumb are like these

1. Count the rows of the items you want to paginate.
2. Once we have gotten the number of rows, divide that number by the items we want to be showing on the page.
3. Give the current page a number designation e.g. 1
4. Calculate the offset. Such as $offset = ($currentpage - 1) * $rowsperpage;
5. Send your database query to fetch the actual items in the database using the criterion of the count as LIMIT.
6. Sit back, relax, analyze, and if it doesn't work go back and do it all over again.

Re: how to insert and retrieve picture from database in PHP

@khialbadshah,

ok here it is I tested this and modify the script a little. This may not be suitable for production site without proper evaluation of the script's security vulnerability.

here we go let's have some fun it is Sunday night, so who cares :)

Step One: go to this site , and download the attached file, unzipped or untar..

Step Two: direct your browser to your phpMyAdmin, create a new database, name this database as test.

Import the following codes to the newly created "test" database above.

CREATE TABLE IF NOT EXISTS `images` (
  `id` int(11) NOT NULL auto_increment,
  `image` blob NOT NULL,
  `title` varchar(255) collate latin1_general_ci default NULL,
  PRIMARY KEY  (`id`)
) 

Whatever you do or modified, this is the most important  [B]`image` blob NOT NULL,[/B] . It has to be like that and nothing else.

Step Three: With your favorite php editor, open the insert.php. Update the database credentials to your database credentials.

$username = "root";
$password = "bananaman";
$host = "localhost";
$database = "test";

, and then just mid-part of the page, find these codes about line 33 down to line 40

// Create the query and insert
// into our database.
$query = "INSERT INTO tbl_images ";
$query .= "(image) VALUES ('$data')";
$results = mysql_query($query, $link);
// Print results
print "Thank you, your file has been uploaded.";

change the above codes to these

// Create the query and insert …

Re: how to insert and retrieve picture from database in PHP

@khialbadshah

You mean a BLOB? right? The cons outweighs the pros with this approach. Are sure you still want to go ahead? You will be exerting more memory than having the images stored in the directory (the conventional way). This method normally applies to images of high value copyrighted images.

Re: Automatization of uploading to YouTube in bulk?

This is just an update just in case someone is following my post above. If you get an error similar to this

Warning: fopen() [function.fopen]: URL file-access is disabled in the server configuration in /……../ on line (..)

The temptation is great to turn the allow_url_include to on. DON'T DO IT for security reason. You only turn this thing to on when there is no other way.

The solution is this..lets create another funtion and just add it above line 6

function get_ytube($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; MSIE 7.0; Windows NT 6.0; en-US)');  
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,10);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch); 

$xml = @simplexml_load_string($output);
return $xml;  
}

and then on line 35 $yt_xml = simplexml_load_file($yt_videoq);

change it to

$yt_xml = get_ytube($yt_videoq);

That should work without putting your server into so much risks....

Re: Automatization of uploading to YouTube in bulk?

Hi,

This may not be the direct answer to the question. However, this is how much you have to write just to send query to youtube using their API. I wrote different types and flavors of this.

It is my day off today and I am just lazy to actually write a more complicated example accessing youtube for upload from a remote server. It can be done.

You can also do a player targeting without refreshing a page as shown here in my old experiment for a client.

<?php
## script was written by PoorBoy from veedeoo.com/forum
## no warranty of any kind, so please don't even bother asking
## Can help during my freetime, but still no guarantee.
#### First we need a function fot get youtube video id
function getPatternFromUrl($url)
{
$url = $url.'&';
$pattern = '/v=(.+?)&+/';
preg_match($pattern, $url, $matches);
//echo $matches[1]; die;
return ($matches[1]);
}
## function above we will use later

## define our query for youtube
$query = "ac+dc";
## define the order by published or viewCount
## viewCount is case sensitive
## you can also do the publisher or author only, read the youtube API about this
$order ="published";
## define start index. Youtube allows you query 50 videos per page, but no more that 1000 per $query
## lets define start index to be 1 . Depending on the result of the query this should return at least 1000/50 = number of pages 
$s_page = 1; …

Re: Button does not work

To some people who maybe wondering why, evstevemd:D suggested to use $_POST or $_GET. I totally agree with him 1000%, please experiment with simple codes below save it as formtest.php run it on your xampp. Warning! this if($_POST) maybe improper in php.

<?php
if($_POST){
## extract ($_REQUEST); ## should use this if more data are coming from the form
$name = $_REQUEST['name'];
$last = $_REQUEST['last'];
echo "$name <br/>";
echo "$last <br/>";
}

elseif($_GET){
extract ($_REQUEST);
$name = $_REQUEST['name'];
$last = $_REQUEST['last'];	
echo "$name <br/>";
echo "$last <br/>";	
}
else{?>
<!-- to demonstrate why $_REQUEST is something to avoid, try changing the method to post, and see what will happen -->
<form method="get" action="formtest.php" />
<input type="text" name = "name" value="enter name here"/>
<br/>
<input type="text" name = "last" value="enter last name here" />
<input type="submit" value="test">
</form>

<?}?>

For the second part, try changing the form method to "post". This example should give us the idea why not use it for applications other than simple non-critical data. Better yet remove the method making it like this method="", and see what will happen again.
