hi guys,

I'm just a newbie in php, trying to create an upload script.
it was working initially, until i start using session, so that i can pass values between pages.

i have few pages, and session is working well, until reaching the last page (upload_process.php).

form.php - flname.php - upload.php - upload_process.php
(gather imput) - (create dir) - (upload files - form) - (upload process/display log)

here is my code for upload_process.php:

PHP Code:


			
<?php 
  // this starts the session 
  session_start(); 
 
  $success = 0; 
  $fail = 0; 
  $uploaddir = 'chenup/'; 
  $max_size = "10000000"; // 50000 is the same as 50kb 
  $totalfiles = "5"; 
  session_start(); 
 
  require('includes/application_top.php'); 
 
  echo '<html ' . HTML_PARAMS . '><head><meta http-equiv="Content-Type" content="text/html; charset=' . CHARSET . '">'; 
  echo '<title>' . TITLE . ' - Upload Photos</title>'; 
  echo '<base href="' . (($request_type == 'SSL') ? HTTPS_SERVER : HTTP_SERVER) . DIR_WS_CATALOG . '">'; 
  echo '<link rel="stylesheet" type="text/css" href="stylesheet.css"></head>'; 
  echo '<body><center><table class="infoBoxContents" border="0" width="100%" cellspacing="0" cellpadding="0"><tr class="infoBoxContents"><td class="infoBoxContents" align="center"><table class="infoBoxContents" border="0" width="90%" cellspacing="8" cellpadding="8">'; 
 
  for ($i=0;$i<$totalfiles;$i++) 
   { 
      if($_FILES['userfile']['name'][$i]) 
       { 
          $uploadfile = $uploaddir . basename($_FILES['userfile']['name'][$i]); 
          $ext = strtolower(substr($uploadfile,strlen($uploadfile)-3,3)); 
 
         if (preg_match("/(jpg|gif|png|tif|pdf)/",$ext)) 
         { 
            // Check File Size 
            if(($_FILES['userfile']['size'][$i] < $_POST['MAX_FILE_SIZE']) || ($_FILES['userfile']['size'][$i] < $max_size)) 
            { 
               if (move_uploaded_file($_FILES['userfile']['tmp_name'][$i], $uploadfile))

The php script will be working if i remark // the session start (). when i unremark it (using session), the page will show http 500 error.

i would appreciate if someone could help me out here. really need your help, thanks.

i will show the rest of the files if you need me to.

btw, i'm hosted on a linux machine.

thanks a lot.

Http 500 errors are generally due to the web server software and usually not a client side problem.

Have you tried creating a simple test script declaring a session to see if that works?

If no sessions are working, you'll need to access your server logs to determine what the problem is with your setup as there'll probably be a session handling error in there. Not being very familiar with Linux that's about as much as I can help.

You need to log into root access to change the folder directory settings to 777 and that should help.

Have you read the instructions file twice because this happend when we doesn't read them carefully? You may reread it and retry again.
