Hello fellow coders :D
I am making a system where people who register can upload files and what not. I found a script that works perfect but wont upload files over 2 mb. Even if I change the file limit, which is 190 mb. Here is the script:

Code: Select all

<?php

require 'db_connect.php';

// require our database connection
// which also contains the check_login.php
// script. We have $logged_in for use.

if ($logged_in == 0) {
	die('<style>body {background-image:url(http://gmuploads.servegame.com/background.png);font-family: Courier New;font-size: 12px;color: FFFFFF;}</style>Welcome to the Garrys Mod Upload website. We provide free hosting for all your GM files.Sorry, but before you can start uploading files you need to <a href=login.php>login</a>, you can <a href=Register.php>register</a> free.');
}


// show content

$db_object->disconnect();
// when you are done.

?>
<?php
//vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
//   You may change maxsize, and allowable upload file types.
//^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
//Mmaximum file size. You may increase or decrease.
$MAX_SIZE = 200000000;
                            
//Allowable file Mime Types. Add more mime types if you want
$FILE_MIMES = array('image/jpeg','image/jpg','image/gif'
                   ,'image/png','application/msword');

//Allowable file ext. names. you may add more extension names.            
$FILE_EXTS  = array('.zip','.jpg','.png','.gif','.rar','.sav','.dem','.avi','.bsp'); 

//Allow file delete? no, if only allow upload only
$DELETABLE  = false;                               


//vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv

The php.ini file has a default limit of 2Mb. That is the value you need to change. If you don't have access to the ini file, then try using the ini_set("upload_max_filesize", value); to increase it. Note that this method only works for the script and you may need to talk to your host about increase the size on amore permanent basis
