Question

I am using Cakephp as my framework. I have a problem in uploading my files through a form. I am using an Uploader plugin from THIS website.

My php ini file has this piece of code.

upload_max_filesize = 10M
post_max_size = 8M

this is from uploader.php –> plugin file has

var $maxFileSize = '5M'; //default max file size

In my controller.php file, i use this code to set max file size as 1 MB at runtime.

function beforeFilter() {
    parent::beforeFilter();

        $this->Uploader->maxFileSize = '1M'; 
}

In the uploader.php, we perform this …

if (empty($this->maxFileSize)) {
    $this->maxFileSize = ini_get('upload_max_filesize'); //landmark 1
}

$byte = preg_replace('/[^0-9]/i', '', $this->maxFileSize);
$last = $this->bytes($this->maxFileSize, 'byte');

if ($last == 'T' || $last == 'TB') {
    $multiplier = 1;
    $execTime = 20;
} else if ($last == 'G' || $last == 'GB') {
    $multiplier = 3;
    $execTime = 10;
} else if ($last == 'M' || $last == 'MB') {
    $multiplier = 5;
    $execTime = 5;
} else {
    $multiplier = 10;
    $execTime = 3;
}


ini_set('memore_limit', (($byte * $multiplier) * $multiplier) . $last);
ini_set('post_max_size', ($byte * $multiplier) . $last);  //error suspected here
ini_set('upload_tmp_dir', $this->tempDir);
ini_set('upload_max_filesize', $this->maxFileSize); //landmark 2

EXPECTED RESULT:
When i try uploading a file that is 2MB of size, it shouldn’t take place because maxFileSize is 1MB at run time. So upload should fail.

THE PROBLEM IS :
But it is getting uploaded.

Landmark 1 does not get executed. (in comments)… land mark 2 does not seem to work…
upload_max_filesize does not get the value from maxFileSize.

Please help me… thank you

Setting upload_max_filesize during the script execution is rather pointless, since by the time the script executes the file is already uploaded and accepted by the server. If you need to reject the file based on size in your script (as opposed to Apache or PHP rejecting it), you need to evaluate the size of the uploaded file and “manually” ignore it if it’s too big.
