Problem with uploading huge files

[ra_ie_darkness]

I'm trying to create a function to upload files on my server

It is working fine but the problem is that it doesn't work when I try to upload files larger than 15/20 mb

function uploadfile()
    {
        global $id;
        $getid = mysql_query("Select * from user where email='$id'");
        while($result = mysql_fetch_array($getid))
        {
            $userid = $result['id'];
        }        
        $dir = "C:\\xampp\\htdocs\\filehost\\";
        $dir.=$userid."\\";
        if($_FILES['usr']['size']>2097152) //2megabytes
        {
           echo "You cannot upload files greater than 2mb";
        }       
        else
        {
            if(move_uploaded_file($_FILES['usr']['tmp_name'],$dir.$_FILES['usr']['name']))
            {
                $fname = mysql_real_escape_string($_FILES['usr']['name']);
                $fsize = $_FILES['usr']['size'];
                $date = date("Y-m-d");
                $dlurl = substr(md5(uniqid()), 0,10);
                $newdir = mysql_real_escape_string($dir);
                $fquery = mysql_query("SELECT * from folder where name ='$userid'");
                while($row = mysql_fetch_array($fquery))
                {
                    $folderid = $row['name'];
                }
                echo "File uploaded";
                if(!mysql_query("INSERT INTO myfile (fileid,userid,fid,name,size,date,location,dlurl) VALUES ('','$userid','$folderid','$fname','$fsize','$date','$newdir','$dlurl')"))
                {
                    echo "Identify";
                }
                else
                {
                    echo "File uploaded";
                }
                
            }
        }
               
            //echo "File moved";
    }

 

I have given a condition which does not allow files larger than 2 mb but instead of getting the message "You cannot upload files greater than 2mb" I get php error messages

 

How can I fix this

What PHP Errors you get?

Your ini is probably not allowing you to upload super-large files.

 

This will allow large file upload, but not advisable:

 

ini_set("upload_max_filesize", "10M");

ini_set("post_max_size", "10M");

 

In fact, you should probably restrict the file size in the browser to prevent bandwidth hogging.

You cannot set the upload size limits using ini_set statements in a script. Php uses those values before it ever invokes a script. You must set them in the master php.ini (when you have access to it), in a local php.ini (when php is running as a cgi application), or in a .htaccess file (when php is running as an Apache Module.) You would also NEED to set them to larger values if you are using php to process uploaded files, so it would be very advisable to change the php settings.

I changed the settings in my php.ini file and it is working now.

Thank you
