Re: Ereg_replace with double quotes

nonshatter 26 Posting Whiz

14 Years Ago

Isn't ereg_replace() deprecated now? Take a look into using preg_quote() instead.

Here's an example:

<?php
// In this example, preg_quote($word) is used to keep the
// asterisks from having special meaning to the regular
// expression.

$textbody = "This book is *very* difficult to find.";
$word = "*very*";
$textbody = preg_replace ("/" . preg_quote($word) . "/",
                          "<i>" . $word . "</i>",
                          $textbody);
?>

This should work the same with asterisks as it does for double quotes

Re: please explain this $_SESSION ARRAY??

This is a multi-dimensional array. The parent index (ddc) is an associative array and the child (price) is also associative. This would have a single value assigned to it:

$_SESSION['ddc']['price'] = "144";

Note: Unlike a real PHP array, $_SESSION keys at the root level must be valid variable names.

<?php 
$_SESSION[1][1] = 'cake'; // fails

$_SESSION['v1'][1] = 'cake'; // works
?>

Okay, What package are you trying to install exactly?

Can you post the output of the following:

Another idea is to use 'Synaptic package manager' to download the package. This is found in system >> administration >> synaptic (if you're using the Gnome desktop environment)

Re: Cannot modify header info +Login fails

nonshatter 26 Posting Whiz

This is most likely because you're echo-ing out stuff before you're header() statement.

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

<html>
<?php
/* This will give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>

<?php
echo "something";
/* This will also give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');

Re: commands

Okay, it's good that you're interested!

Let's take an example:
You have a file which is 1Gb in size. You know that opening the file in the shell (e.g using 'cat') is going to be inefficient, as you'll have to scroll through a lot of lines to get to where you want to look. So less and more are basically alternatives to save resources and/or to only select the information that you're interested in.

The default behaviour of more is that the file content scrolls up one screen height at a time, and the space bar is used to advance to the next page. The command less is a more sophisticated version of more. Less can scroll backwards and has many more options over more. (There is plenty of information about this on the web).

If you're viewing a large log file and are only interested in what's happened most recently, then I would usually recommend using 'tail -f file.log' which would display the last 'x' number of lines of that file.

Shama,
You'll need to be a bit more specific. What Linux are you running? What command are you issuing to get that error? I guess you're using Ubuntu?

You could try

sudo apt-get update               // This will update your repository

and then

sudo apt-get install < name of package >

Re: Installing .exe programs on Ubuntu

nonshatter 26 Posting Whiz

14 Years Ago

Well an .exe is an executable built for the windows environment, so getting it to run on any linux box isn't always possible.

However, there is some emulation software you can try. The most well known is Wine:

Wine is a program that offers a compatibility layer allowing Linux users to run some Windows-native applications inside of Linux. Wine is not the ideal. Ideally, you should find native Linux applications. You can use Ubuntu's software package manager to search for easily installable native Linux apps, or you can explore OSalt or Linux App Finder to find alternatives for specific Windows programs.

Not all Windows applications run in Wine. And some that do require extra configuration in order to work. You may want to consult the Wine HQ app database to see if the Windows application you're thinking of installing through Wine will work well with Wine or not. Platinum-rated applications will work with no extra configuration. The example on this page is a platinum-rated application.

Re: How To Change The Default PHP Install Directory?

nonshatter 26 Posting Whiz

14 Years Ago

Yes you're correct. I remember doing this on an old legacy system (SLES 9.3).

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql

Where prefix is the target installation directory, and the apxs2 switch is mandatory. But be wary, if you forget to add a specific module (e.g. php5-mysql, mod_ldap etc) at some point, then you'll have to go round the loop again (re-configure and re-make), adding the new switch options. I remember it being a bit of a pain to get all aspects of functionality to work!

Perhaps save your final configure command in a text file so you can refer back to it if you need to.

Hope that helps,

Re: Strip a word from a variable

nonshatter 26 Posting Whiz

14 Years Ago

Yes this is possible. But the solution will depend on whether the $from variable always starts with INTERVAL, or whether it changes...

If it is always going to start with INTERVAL, then you could use a simple substr() function to cut off the first word. This simply says to print everything after the 8th character, counting I as 0, N as 1, T as 2 etc.

<?php
    $new_from = substr($from, 8);
    echo $new_from;
?>

The syntax for substr is

string substr ( string $string , int $start [, int $length ] )

Alternatively, if the first word changes you could look into using explode() (using space as the delimiter)

<?php
// Example
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2 
?>

Re: What's my error with fwrite and fopen

nonshatter 26 Posting Whiz

14 Years Ago

Okay, the error your getting means that fopen can't open the file you're requesting because the permissions of that file (or directory) won't allow it.

If you're server is on Linux:
From the shell cd to the directory where that file resides, and issue

chmod 777 *

This will give you full read/write/execute permissions to all files in the directory, and prevent the error from occurring again.

If you're running your site from a web host, check with them for how to change your permissions.

Re: Change the image onclick

Not to worry, I managed to solve it using a for loop, although this doesn't allow me to use more descriptive names for the table ids:

onload = function() {
	cookie = new Cookie('sections', 200000);
	cookie.load();
	for(x=0; x < 4; x++) {
		var table = getItem("table_" + x);
	    if(table) {
		    var sections = table.getElementsByTagName('tbody');
		    var sectionRef;
		    for(var i=0; i<sections.length; i++) {
			    if(!sections[i].id || sections[i].id.indexOf(prefixes.section) == -1) { continue; }
			        sectionRef = sections[i].id.replace(prefixes.section, '');
			    if(cookie[sectionRef] === '0') { toggleItem(sectionRef); }
		    }
		}
	}
}

Let me know if you have a better solution. Consider it solved.

Re: Change the image onclick

Works perfectly! Thanks again.

Just one last thing - When I add more than one table to the page, I can't seem to get more than one table state (collapsed/open) to be remembered upon page refresh. This probably has a simple solution.

I guess it's this function here that's causing the problem. Is it possible to make this more dynamic.

onload = function() {
	cookie = new Cookie('sections', 200000);
	cookie.load();
	var table = getItem('table1');   //This needs to cater for 2+ tables
	if(table) {
		var sections = table.getElementsByTagName('tbody');
		var sectionRef;
		for(var i=0; i<sections.length; i++) {
			if(!sections[i].id || sections[i].id.indexOf(prefixes.section) == -1) { continue; }
			sectionRef = sections[i].id.replace(prefixes.section, '');
			if(cookie[sectionRef] === '0') { toggleItem(sectionRef); }
		}
	}
}

The tables/images have test id names for now:

<table id="table1" width="100%">
           <tr>
	       <td>
                    <a href="#" onclick="return toggleItem(1)"><img id="image_1" src="/minus.gif" href="" align="left"></a>Backup Information:
               </td>
           </tr>
	   <tbody id="section_1">
	   <tr class="headers">
			<td><strong>Backup Date:</strong></td>
			<td><strong>Total Size Backed Up:</strong></td>
	   </tr>
	   <tr>
			<td>Gb</td>
			<td>cho $backup['duration']</td>
	   </tr>
	   </tbody>
	</table>

	<table id="table2" width="100%">
           <tr>
		<td>
                     <a href="#" onclick="return toggleItem(2)"><img id="image_2" src="/minus.gif" href="" align="left"></a>Backup Information:
                </td>

Re: PHP MYSQL UPDATE issue

perhaps your form values aren't being passed correctly.
Perform a check to see if they're set first:

if(isset($_SESSION['user_id']))
{
   echo "it's set";
}

Or alternatively simply echo out each of the $_POST values to see if they're all there

		</tr>
	</tbody>
</table>

So what I'm trying to do is display the image /path/to/plus when the table is closed, and then display the image /path/to/minus when the table is open.

Can anyone help me?
Thanks, ns

echo $messageproper;

Something like this should work but check the syntax, you might need to play around with the quotes to get it working properly...

Re: question

Hey, if you want a visual counter look here: http://www.hashemian.com/tools/javascript-countdown.htm

A countdown timer is something that needs to be done client-side e.g. in javascript.

This is one I've used previously. Once you get it counting down from 60 seconds post your code and we can implement the redirect.

That's still wrong Cossay. Tables are block-level elements, thus you can't be aligned. The syntax doesn't look right either

Can you post all your code so far and put your separate pages in separate code tags with their file name at the top. This will make it easier to help you.

nonshatter 26 Posting Whiz

So you want the table with the values in, and then assign them to $messageproper? What are you using messageproper for?

You can do it exactly the same way as you'd done previously. I'm not sure if you still want the line breaks in there or not though.

// table with the values goes here...


//then assign the values to the messageproper variable.
$messageproper ="\n\n" .
		"Name: " .
		ucwords($_POST['name']) .
		"\n" .
		"Email: " .
		ucwords($email) .
		"\n" .
		"Message: " .
		$_POST['message'] .
		"\n" .
		"\n\n" ;

But name message and email are individual variables being assigned to $messageproper. So my code should work.

You have no html in that code!...

<?php

  // ---- your code ---- //

?>
<html>
<table>
  <tr>
      <td>name</td>
      <td>email</td>
      <td>message</td>
  </tr>
  <tr>
      <td><?php ucwords($_POST['name']); ?></td>
      <td><?php ucwords($email); ?></td>
      <td><?php $_POST['message']; ?></td>
  </tr>
</table>
</html>

tr creates a new row, td creates a new cell

Re: fullscreen php templates

You shouldn't need a template to do this! Just look at the CSS.

The easiest way to do this is to create a <div> tag that wraps around all your content, then specify the width of it using CSS.

<html>
<head>
<style type="text/css">
  container {
    width: 100%;
}
  </style>
</head>
<body>
    <div id="container">
        ------PUT ALL YOUR CONTENT HERE-----
    </div>
</body>
</html>

Re: download zip file from another website

Hi Vego, this shouldn't be a problem if they're making the file readily available to you! wget shouldn't have a problem downloading large files either.
First install wget (if it isn't already installed by default), then play around with the syntax options. When you can download the file you want, you can set up the scheduled task so that it will automate the download.
Hope that helps

Re: download zip file from another website

If you are using Linux, you can set up a cron job. The cron daemon provides the ability for a system administrator or any other user (if permitted to do so) to automate the routine running of scripts, tasks or any other server function on a regular basis. You can use 'crontab -e' to set up your scheduled task. Or on windows you can use the "scheduled tasks" tool, although I don't think this is as good.
Then you will also need some sort of script or program to execute and download your file every X number of hours or X number of days.
Do you know where the file is located? Do you have access to their web server directories? FTP?

There is a tool I use for this sort of thing called wget (again, I use linux for this). An example command you could use would be something like:

wget -c -r –passive-ftp -nH ftp://:@//ftp_dir/*.zip

Look here for more example usage: http://www.editcorp.com/Personal/Lars_Appel/wget/v1/wget_7.html

So if this is your edit page: I have changed the form action to post the form to the same page as it is clearer to explain this way:

<form action="<?php $SERVER['PHP_SELF'] ?>" method="post" >
Name:<br />
<input type="text" name="Name" size="30" /><br />
Email:<br />
<input type="text" name="Email" size="30" /><br />
Comment:<br />
<input type="text" name="Comment" rows="80" cols="80" /><br />
<input type='submit' name="save" value="save" />
</form>

<?php
if(isset($_POST['save']))    //determine whether the button is clicked
{
    $name = $_POST['Name'];       //gather the form values
    $email = $_POST['Email'];
    $comment = $_POST['Comment'];
    
    //update query
    $update = mysql_query("UPDATE table SET name='$name', email='$email', comment='$comment' WHERE userID='12'") or (mysql_error());      
}
?>

You could also pre-populate these fields with the users existing details using the value attribute, but you'd have to pass them from the previous page or get their details from the database.

<input type="text" name="Name" size="30" value="$name"/>

Re: Php/Mysql Error?

So what's the error you're getting? Try this and report back with the error message:

$Query = mysql_query("INSERT INTO products (title, url, finalurl, category, owner, shortdescription, longdescription, price, rank, tag1, tag2, tag3) VALUES ('$Title','$Random_Number','$url','$Category','$Username','$SD','$LD','$Price','0','$Tag1','$Tag2','$Tag3')") or die(mysql_error());

echo "Yes! Your product was created I hope " . $Title . " will rank high!";

If there's a syntax error in the mysql statement, the code will stop executing (or die()). If there is no error, then it will echo the success message.

Okay, the correct way to do this will depend on what your form action and method are set to do. If you could post your form code I should be able to help.

Re: initialising $_GET problem

You get this error message because you're trying to retrieve $_GET from the URL when it doesn't exist. Why not check whether the variable exists before deciding what to do with its value.

E.g.

<?php
    if (isset($_GET['start'])) { $start = $_GET['start']; } 
    else { $start = 0; }  
?>

Alternatively, add the start variable in the URL that links to the first page, then you wouldn't have this problem.

<a href="/VIEW_in_STEPS5b.php?start=0"

Re: Website in PHP and MySQL

I don't see a question :O

I suggest you start small, rather than jump in the deep end. First download and install apache web sever, mysql + php. Or download XAMPP - it is an easy install and will give you all the software you need to start developing on your local machine.

Then create a small database table and connect to it using PHP, then try pulling and pushing data in/out of it. There is mounds of information online on how to do this.

I developed an online auction website for my final yr project. It's a pretty good project to do - lots of potential for interactive and business-like features.

And to add to that - in my opinion, for a final year project it shouldn't really matter if a jQuery feature doesn't work with a certain version of a web browser... So long as you can explain why it may not work, perhaps providing an alternative feature or workaround for older/incompatible browsers!

Re: How to learn PHP?

If it's books you want, I'd recommend PHP and MySQL Web Development by Luke Welling and Laura Thomson (try and get the 3rd edition).
I managed to pick up a 2nd hand copy for £5 on Amazon.
Otherwise tiztag and w3schools are good places to start.

executing an external program using exec()

nonshatter 26 Posting Whiz

14 Years Ago

Hi all,
How can I execute an external program (wget) on a linux box? I assume I should be using exec() or something similar.
The command I'm trying to execute is:

wget -p 'x.x.x.x/inventory.ssi?mag_0=1&mag_1=1'

Which returns the html page of inventory. I am then parsing the file using DOMDocument to extract the relevant text.
Running this in the terminal yields the result I want.

If I simply do this:

exec("wget", $ret);
	foreach($ret as $value)
	{
		echo $value;
	}

Then it prints the wget usage options to the browser, but issuing my command seems to do nothing?
Cheers
