php jquery jcrop and imagejpeg

Question

That's my first approach with GD stuff. I'm trying to implement resize and crop using jcrop jquery plugin. I still can't figure out how to save the image I've cropped. On the jcrop site there's not much about it. here's my code:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $targ_w = $targ_h = 150;
    $jpeg_quality = 90;

    $src = 'demo_files/flowers.jpg';
    $img_r = imagecreatefromjpeg($src);
    $dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

    imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
            $targ_w,$targ_h,$_POST['w'],$_POST['h']);

     header('Content-type: image/jpeg');

     imagejpeg($dst_r,null,$jpeg_quality);

    exit;
}

What do I do with imagejpeg($dst_r,null,$jpeg_quality) in order to actually write the image file and save its path in my db?

Thanks in advance.

If you want to save the file instead of outputting it, do these two things:

• Remove the line header('Content-type: image/jpeg');
• Change the next line after that to imagejpeg($dst_r, 'path/to/output.jpg', $jpeg_quality);

See the docs for the imagejpeg() function at php.net/imagejpeg
