Dynamic Image and Data Upload Simultaneously

[ivoilic]

Ok so I have a form to submits to a .php file that creates an image.  This works fine, but I also want the info from the form to be sent to MySQL database.  The problem is that something in a script I "required" called core.inc.php is interfering and so no image is output.  Here is core.inc.php:

<?php
ob_start();
session_start();
$current_file = $_SERVER['SCRIPT_NAME'];

if(isset($_SERVER['HTTP_REFERER'])&&!empty($_SERVER['HTTP_REFERER'])) {
$http_referer = $_SERVER['HTTP_REFERER'];
}

function loggedin() {
if(isset($_SESSION['user_id'])&&!empty($_SESSION['user_id'])) {
	return true;
} else {
	return false;
}
}

function getuserfield($field) {
$query="SELECT `$field` FROM `Users` WHERE `id`='".$_SESSION['user_id']."'";
if($query_run=mysql_query($query)) {
	if($query_result = mysql_result($query_run, 0, $field)) {
		return $query_result;	
	}
}
}

?>

 

Here is the code for the image creating .php file:

<?php
require 'connect.inc.php';
require 'core.inc.php';
$title = $_REQUEST['title'] ;
$user_id = getuserfield('id');
$query = "INSERT INTO `---` VALUES ('".mysql_real_escape_string($title)."','".mysql_real_escape_string($user_id)."')";
$query_run = mysql_query($query);
//There is some more code in here obviously, but it's irrelevant 
header('Content-type: image/png');
imagepng($image_f);
imagedestroy($image_f)

 

Can anybody give me some idea of what is conflicting or what I can do to fix it?

It looks like there's some whitespace at the end of core.inc.php. That shouldn't be there. Easiest way to avoid that kind of problem is to just forgo the end tag. Leave it out. It's not like it's necessary.

sorry i'm pretty new at this can you clarify

At the very end.

?>

Try removing the ?> entirely.

YES it worked!  Thanks so much.  If it's not to much trouble can you tell me why that actually worked.
