Multiple File upload - need help with validating file size

Discussion in 'PHP' started by izbryte, Mar 5, 2012.

    I have this validation script for a multiple file upload form and it works great until I add in the validation for the max file size. This doesn't seem to work at all. I'm at the point, I'm ready to pull my hair out and I'm willing to pay someone to help if necessary.
    Here's my code:
    if (isset($_POST['Submit'])) {
    	$user_id = $userdata[user_id];
        $number_of_file_fields = 0;
        $number_of_uploaded_files = 0;
        $moved_files = 0;
        $uploaded_files = array();
    	$max_filesize = 5242880; // Maximum filesize in BYTES (currently 5MB).
        $upload_directory = dirname(__file__) . '/'.$user_id.'/'; //set upload directory
    	if (!is_dir($upload_directory)) {
        mkdir($upload_directory, 0777, true);
        for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
            if ($_FILES['images']['name'][$i] != '') { //check if file field empty or not
    			if($_FILES['images']['size'][$i] > $max_filesize){
    				echo "<b class='red'>Max file size is 5MB.</b><br/>";		
    				$sz = false;
    			}else{ $sz = true;}
    			$ext = validate_extension($_FILES['images']['name'][$i]);
    			if (($ext == true) && ($sz == true)){
    				$uploaded_files[] = $_FILES['images']['name'][$i];		
    				if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) {
    			}else { 
    			echo "<b class='red'>File extention error. Only .doc, .pdf, .jpg and .gif files are allowed. </b><br/>";
    	if ($number_of_uploaded_files >= 1){
    		echo "Number of files submitted:<b class='red'>".$number_of_uploaded_files."</b><br/>Number of successfully uploaded files:<b class='red'>".$moved_files."</b><br/><br/>Uploaded File Name(s):<br/>" . implode('<br/>', $uploaded_files) .', '. implode('<br/>', $uploaded_file_size);

    maybe the files you uploaded are really over the max file size?

    this can be an issue of host. check the max_upload_limit in php.ini details. it really can be a pain in ass ,as was for my case

    You can try to do some modifications in .htaccess. See wether it's allowed or not.
