[Resolved] Image resize on upload

[dud3r]

So I have an upload script

$dir = $pic_upload_dir; //upload dir /var/www/html/
$files_name = (str_rand(7, '123456789').".jpg"); // creates a random number then adds extension of .jpg to it

//-- checks a bunch of stuff here but it's irrelevant -//

move_uploaded_file($_FILES['file_field_main']['tmp_name'], $dir."/".$files_name);

Ok, let's say I upload 1024x768 image, but the allowed size is only 400x300, how do I make the script resize the large image into the smaller image and upload it to the image dir?

I'm confused. How do you call it from the upload page?

Nevermind.

Here it is:

$filename = $_FILES['file_field_main']['tmp_name']; 
$width = 400; 
$height = 300; 
header('Content-type: image/jpeg'); 
list($width_orig, $height_orig) = getimagesize($filename); 
if ($width && ($width_orig < $height_orig)) { 
       $width = ($height / $height_orig) * $width_orig; 
    } else { 
       $height = ($width / $width_orig) * $height_orig; 
    } 
    $image_p = imagecreatetruecolor($width, $height); 
    $image = imagecreatefromjpeg($filename); 
    imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); 
    imagejpeg($image_p, $_FILES['file_field_main']['tmp_name']);
