Re: Im stuck can anyone help please....

Maybe you have more than a row in your result set? Try:

echo $count;

To avoid this problem you can add limit to the query:

$sql ="SELECT * FROM `task_2` WHERE `username` = '$myusername' and `password` = '$mypassword' limit 1";

Re: Im stuck can anyone help please....

No problem, you are using quotes around the name of the table 'task_2':

$sql ="SELECT * FROM 'task_2' WHERE username = '$myusername' and password = '$mypassword'";

I suggested you to replace them with backticks otherwise it's treated as a value, so change the query line as here:

$sql ="SELECT * FROM `task_2` WHERE `username` = '$myusername' and `password` = '$mypassword'";

Spot the difference:

'task_2' <- wrong
`task_2` <- correct

In order to see the error use mysql_error():

$result = mysql_query($sql) or die(mysql_error());

Use backticks for table and field names, and quotes only for values as here:

Re: Six Nations

cereal:

Italy only looked a shadow compared to the France game the weekend before. To be brutally honest, the number 10 was back to normal Italian 10 form against Scotland as in couldn't kick for toffee.

Don't get me wrong, I'm not anti-Azzurri (they have the legendary Castro after all - I'm a long-time Tigers fan) but the team still has a lot of problemns when it comes to playing mature and consistent rugby.

I completely agree, we have a lot of experience to gain.. I just hope we are not going to conquest the 10th wooden spoon.. :D

Re: Performing a Data Push Back from a Php server script

Ok, you need Ajax and a script to receive, save and return data from the form, FB uses also a cache to save data and return, here I create an example with JQuery framework, we are going to save it only to the database:

create table message_board(id int(9) not null auto_increment primary key, message varchar(255) not null, creation_date datetime not null) engine=myisam default charset=utf8;

The form page:

<?php

$q = mysql_query('select * from message_board order by id desc');

?>

Ok then use mysql_error() the query fails, maybe because the variables are not set:

mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `recover_password` = '$recover_password'") or die(mysql_error());

A part from that consider to use mysql_num_rows() for this task, something like: mysql_num_rows($q) > 0 ? true : false;

Re: sort array problem

A foreach loop will work:

foreach($ab as $k => $v)
{
    echo "$k  -  $v \n";
}

If you wan to group them in different arrays then use:

$keys = array();
$values = array();
foreach($ab as $k => $v)
{
    $keys[] = $k;
    $values[] = $v;
}

print_r($keys);
print_r($values);

Or better use array_keys() and array_values():

$ab = array('0'=>'10','1'=>'5','2'=>'8');
$ba = $ab;
asort($ba);

print_r(array_keys($ba));
print_r(array_values($ba));

Ok?

Re: Why Is Sending A Password In Plain Text A Bad Idea?

Also, if you want to resend passwords then create a new one automatically, or use AES_ENCRYPT / AES_DECRYPT in MySQL, change the password field to text or blob as in this example:

CREATE TABLE `users_test` (
`id` int(9) NOT NULL AUTO_INCREMENT,
`username` varchar(255) NOT NULL,
`password` blob NOT NULL,
`password_hash` varchar(40) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8

And then try:

INSERT INTO users_test (username, password, password_hash) VALUES ('username',AES_ENCRYPT('my_password','hash'),sha1('my_password'));

If you go to perform a normal select you get:

select * from users_test;
+----+----------+------------------+------------------------------------------+
| id | username | password         | password_hash                            |
+----+----------+------------------+------------------------------------------+
|  1 | username | <F8><E9><?<F4>^L<8B>^Y<9A><84><8C>4\<8D><AA>^B          | 5eb942810a75ebc850972a89285d570d484c89c4 |
+----+----------+------------------+------------------------------------------+

But if you use AES_DECRYPT:

select id, username, AES_DECRYPT(password,'hash') as password, password_hash from users_test;

+----+----------+-------------+------------------------------------------+
| id | username | password    | password_hash                            |
+----+----------+-------------+------------------------------------------+
|  1 | username | my_password | 5eb942810a75ebc850972a89285d570d484c89c4 |
+----+----------+-------------+------------------------------------------+

You get the correct value. So, this is a safer solution than plain text:

Re: Looping through array from another array

The first problem is $xx which is a string:

var_dump($xx); # output: string(5) "$_GET"

if you want to assign _GET as variable name then use $$ as:

$xx = '$' . $value;
var_dump(${$xx}); # output: Notice: Undefined variable: $_GET

but as seen, this is not enough, so change it to:

var_dump(${$value});

and by running /test.php?a=hello&b=world you will get what expected:

array(2) { ["a"]=> string(5) "hello" ["b"]=> string(5) "world" }

so at the end write:

$xx = ${$value};

Re: FTP Delete Folder And Subfolders

You should get the file list inside the directory to delete, loop ftp_delete() for each and ftp_rmdir() for each subdirectory, but they need to be empty as the main directory to delete. So it's a bit tricky, the functions you need to use are:

ftp_delete()
ftp_nlist()
ftp_rmdir()

http://php.net/manual/en/ref.ftp.php

You can also use functions like opendir(), unlink() and rmdir():

unlink('ftp://user:password@ftp_server');

but in the case of rmdir and ftp_rmdir the directory needs to be always empty and you need permissions, so in some occasions you'll need to use chmod() or ftp_chmod() since the ftp user is different from the server user, usually www-data.

In Addition
If you have to do a lot of this activity it could be better to place a script in the remote server, use cron to make it wait instructions and from local send a simple file or $_POST with the name of the directory to delete, you can use ftp_* or even curl. Just make sure that these ftp accounts are jailed otherwise it becomes dangerous.

Re: Redirect user from their IP

You can use GeoIP library, for example:

$countrycode = geoip_country_code_by_name($_SERVER['REMOTE_ADDR']);
$loc = '/default/contents';
switch($countrycode)
{
    case 'FR':
        $loc = '/fr/contents';
    break;
    case 'IT':
        $loc = '/it/contents';
    break;
    case 'US':
        $loc = '/us/contents';
    break;
}

header('Location: '.$loc);

at that point you can also place a cookie to switch automatically each time the user comes back, but in order to use it you have to install the library:

This can be done with PECL or by command line, in debian/ubuntu type:

sudo apt-get install php5-geoip

Note, some of the functions as geoip_region_* will not work if you don't load the correct database, some of them are only available by payment, by default you get the Country database both IPV4 and IPV6, there is also the City db available for free:

In case you want to use it: download it, use gunzip to decompress the file gunzip GeoLiteCity.dat.gz and place it inside /usr/share/GeoIP/

EDIT
As side note, this can work also with other free GeoIP databases, but I didn't tested.

Hope is useful, bye.

First this is wrong:

if ($sql = $s){

here you are assignin a value, not comparing, to compare use == or for boolean ===, so rewrite it to:

if ($sql == $s){

Second, I don't see $sql declared anywhere, you will get an error here.
Third, you have to extract the filename from the query:

if(mysql_num_rows($t) > 0)
{
    # loop results
    while($row = mysql_fetch_object($t))
    {
        unlink('/path/'.$row->filename); # and extension if this is saved a part
    }
    header('Location: lee_remove.php');
}

bye!

Re: Points and Endorse Buttons Don't Work

Same problem here. By the way, I don't know if this was already the behave: it seems Business Exchange requires log in.

Re: Url redirection plz

If you can, change the DocumentRoot in the Apache httpd.conf file or inside the virtual host configuration file:

DocumentRoot /var/www/website/abc

http://httpd.apache.org/docs/2.2/urlmapping.html#documentroot

Re: Connect Codeigniter to Oracle 11g

As already suggested elsewhere change:

$db['default']['hostname'] = "//localhost/";

to:

$db['default']['hostname'] = "localhost";

bye.

Re: TCPDF library issue pdf not creating correctly

This kind of libraries usually are very strict, so if there's something wrong in your HTML then it will break with an error like yours. It will be more useful if you paste here the code of your page.

In addition, as suggestion, get the HTML output and try to validate it:

http://validator.w3.org/

bye!
