What is wrong?? :(.

The .png is in the same folder, and so is .htaccess, which is:

RewriteRule ^/([a-z]+)\.png$ /anything.php?user=$1

^ Webhost told me i dont need <PHP> tags in .htacess

Where is your $img_handle value ?

[diafol]

this is a "cleaned" copy of your code. No code is run following 'return'. Why are there standalones after the function?

<?php
function sql_sanitize( $sCode ) {
	if ( function_exists( "mysql_real_escape_string" ) ) { // If PHP version > 4.3.0
		$sCode = mysql_real_escape_string( $sCode ); // Escape the MySQL string.
	} else { // If PHP version < 4.3.0
		$sCode = addslashes( $sCode ); // Precede sensitive characters with a slash \
	}
	return $sCode; // Return the sanitized code
	
	$dbhost = 'xxx'; $dbuser = 'xxx'; $dbpass = 'xxxx'; $dbname = 'xxxx'; 
	if (isset($_GET['user'])) { 
		$username = sql_sanitize($_GET['user']); 
	} else { 
		die("no charname given"); 
	} 
	$serverdesc = 'Majuzza Gaming: Roleplay Character Statistics'; 
	$pathtoimg = 'stats_img.png';
	extract($row);
}

ImagePng ($img_handle);
ImageDestroy ($img_handle); //Close the Database connection just in case it didn't do it already mysql_close($conn);
 
?>

Hi thanks ardav but that code didn't work, you deleted lots of the code it needed.

I re-added some of the code to yours but then i got these errors:

Warning: imagestring(): supplied argument is not a valid Image resource in

For this code:

ImageString ($img_handle, 2, 25, 7, "$serverdesc", $color);

I just followed an online tutorial to help me make dynamic signatures, and it will display fields in the MySQL database where the username is index.php?user=USERNAME, and it will display like my level, money etc on the picture.

Tutorial link: http://www.vbgore.com/Dynamic_Signature

I hope someone can help!

I thought I just took out the comments. ANyway - this is wierd:

function sql_sanitize( $sCode ) {
 
       if ( function_exists( "mysql_real_escape_string" ) ) { // If PHP version > 4.3.0
               $sCode = mysql_real_escape_string( $sCode ); // Escape the MySQL string.
       } else { // If PHP version < 4.3.0
               $sCode = addslashes( $sCode ); // Precede sensitive characters with a slash \
       }
       return $sCode; // Return the sanitized code

see that

return $sCode

line? That halts all code execution after that point in the function

Oh, if you read my PM i want it, so if i type in http://website.com/index.php?='USERNAME', it will get the fields from 'USERNAME', but i want it so you cannot mySQL inject it.

Do you understand?? :(.

[diafol]

I don't respond to PMs. All issues regarding a thread should be in the thread.

You include the function and two calls to other functions in your first post. You don't call sql_sanitize() anywhere other than within the function itself. SO the DB details are never initialized and there is no extract.

ImagePng ($img_handle); ImageDestroy ($img_handle);

I don't understand what these are supposed to do when $img_handle doesn't exists (AFAIK).
