Question

I have a script;

        $fileName = $_FILES['userfile']['name'];
        $tmpName = $_FILES['userfile']['tmp_name'];
        $fileSize = $_FILES['userfile']['size'];
        $fileType = $_FILES['userfile']['type'];

        // get the file extension first
        $ext = substr(strrchr($fileName, "."), 1); 

        // make the random file name
        $randName = md5(rand() * time());

        // and now we have the unique file name for the upload file
        $filePath = $imagesDir . $randName . '.' . $ext;

        $result = move_uploaded_file($tmpName, $filePath);
        if (!$result) {
            echo "Error uploading file";
        exit;
    } 

if(!get_magic_quotes_gpc()) {

        $fileName = addslashes($fileName);
        $filePath = addslashes($filePath);

    }

which am using to upload images but I would like to add a script to resize the image to a specific size before it’s uploaded. How do I do that???

EDIT: I have updated this to include your script elements. I’m starting from the point where you obtain your filename.

Here is a very quick, simple script to do it:

$result = move_uploaded_file($tmpName, $filePath);
$orig_image = imagecreatefromjpeg($filePath);
$image_info = getimagesize($filePath); 
$width_orig  = $image_info[0]; // current width as found in image file
$height_orig = $image_info[1]; // current height as found in image file
$width = 1024; // new image width
$height = 768; // new image height
$destination_image = imagecreatetruecolor($width, $height);
imagecopyresampled($destination_image, $orig_image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// This will just copy the new image over the original at the same filePath.
imagejpeg($destination_image, $filePath, 100);
