Posted: Thu Mar 26, 2009 9:20 am Post subject: [HELP] PHP File upload system

i have gone through the code several times, i can't find what is wrong with it. sometimes i get an error to say check that the folder is chmod 777. or it just takes the piss(takes forever) to upload. and then it doesn't upload.

here is my code. please bear in mind it is powered by phUploader.

Code:

<?
error_reporting(7);
$max_file_size="50000";
$max_combined_size="150000";
$file_uploads="3";
$websitename="Upload";
$random_name=false;
$allow_types = array("jpg", "gif", "png", "zip", "rar", "txt", "doc", "exe", "rar", "zip", "swf", "docx", "fla", "flv", "mp4", "psd", "sql", "mp3");
$folder="./uploads/";
$full_url="http://matt.imhotek.net/upload/uploads/";
$fullpath="";
$password="";
$password_md5=md5($password);
If($password) {
If($_POST['verify_password']==true) {
   If(md5($_POST['check_password'])==$password_md5) {
      setcookie("phUploader",$password_md5,time()+86400);
      sleep(1); //seems to help some people.
      header("Location: http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']);
      exit;

   }
}
}
$password_form="";
If($password) {
If($_COOKIE['phUploader']!=$password_md5) {
   $password_form="<form method=\"POST\" action=\"".$_SERVER['PHP_SELF']."\">\n";
   $password_form.="<table align=\"center\" class=\"table\">\n";
   $password_form.="<tr>\n";
   $password_form.="<td width=\"100%\" class=\"table_header\" colspan=\"2\">Password Required</td>\n";
   $password_form.="</tr>\n";
   $password_form.="<tr>\n";
   $password_form.="<td width=\"35%\" class=\"table_body\">Enter Password:</td>\n";
   $password_form.="<td width=\"65%\" class=\"table_body\"><input type=\"password\" name=\"check_password\" /></td>\n";
   $password_form.="</tr>\n";
   $password_form.="<td colspan=\"2\" align=\"center\" class=\"table_body\">\n";
   $password_form.="<input type=\"hidden\" name=\"verify_password\" value=\"true\">\n";
   $password_form.="<input type=\"submit\" value=\" Verify Password \" />\n";
   $password_form.="</td>\n";
   $password_form.="</tr>\n";

   $password_form.="</form>\n";

Seems to work fine on my local server. Use chmod('./uploads/', 0777); to set the chmod for that folder, unless you have access to the server. It seems PHP is having a timeout on long uploads, thus canceling them. Try adding set_time_limit(0); to the top of your code.

You should learn how to use ajax so that you can actually view the upload progress. _________________ Intel over amd yes.
