Session destroyed?

Ok, I'm really lost here. I tried everything, but it doesn't seem to work.

I'm using an upload script (uploadify) and I want to enter the username with the name of the image in the database. But for some reason the username is always blank.

Here is my code:

PHP:

<?php
session_start();

//Error logging
include("../logger.php");
$handler = new Logger(LOGGER_ALL, METHOD_LOG);
set_error_handler(array($handler, "Handle"));

//Watermark class
require_once 'phpgdwatermarker.php';

I have checked all the scripts I'm including for DESTROY SESSION or if a session is opened, but I can't find anything.

I also changed the variable for the login session to different names, but without any luck.

I'ts already 2 hours now that I'm trying to solve this, but I just can't figure out what I'm doing wrong.

Thanks in advance for any help.

Ok I solved it by posting the username to the upload page. But it's still weird I can't use SESSION in the upload page.

Hi Alexander,

Thanks for your answer.

I did what you asked. I'm still working on localhost, so I skipped tip number 1.

For the second one they are the same, but the problem still exists. The session variable disappears every time I try to use it. Instead I have to post it as hidden field to the next document if I want to use it.

Here is another example:

PHP:

// Set the path to the image to watermark
        $input_image = $targetPath.$newName; 
        // Read in the text watermark image
        $myName =  $_SESSION['_amember_login'];
        $watermark = imagecreatefrompng("../watermarks/{$myName}.png");  

        // Returns the width of the given image resource  
        $watermark_width = imagesx( $watermark );
        //Returns the height of the given image resource    
        $watermark_height = imagesy( $watermark );    
        $image = imagecreatetruecolor( $watermark_width, $watermark_height );    
        $image = imagecreatefromjpeg( $input_image );
        // Find the size of the original image and read it into an array      
        $size = getimagesize( $input_image );  
        // Set the positions of the watermark on the image
        $differenceX = $size[0]  - $watermark_width;
        $differenceY = $size[1] - $watermark_height;

        $dest_x = round($differenceX / 2); 
        $dest_y = round($differenceY / 2);   

        imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);   
        // Save the watermarked image as watermarked.jpg 
        imagejpeg( $image, "watermarked.jpg" );
        // Clear the memory of the tempory image     
        imagedestroy( $image );    
        imagedestroy( $watermark );    


No matter what I do, I can't get it to point to "..watermarks/moonwalker.png"
If I use a hidden posted variable, it works fine.

Thanks.
