Question

I am working on a form that adds employee information to a MySQL table and I need to attach a single photo to the file. This is part of a Content Management System and the users do not know how to resize photos, so I need to resize the image to a set size after it is uploaded. How can this be done with PHP? Please note, I am not trying to accomplish a thumbnail image, simply scale the one that is uploaded.

You should check out Verot ‘s php upload class. It handles all image modification options through very simple coding.

Example code:

$foo = new Upload($_FILES['form_field']);
if ($foo->uploaded) {
  // save uploaded image with no changes
  $foo->Process('/home/user/files/');
  if ($foo->processed) {
    echo 'original image copied';
  } else {
    echo 'error : ' . $foo->error;
  }
  // save uploaded image with a new name
  $foo->file_new_name_body = 'foo';
  $foo->Process('/home/user/files/');
  if ($foo->processed) {
    echo 'image renamed "foo" copied';
  } else {
    echo 'error : ' . $foo->error;
  }
  // save uploaded image with a new name,
  // resized to 100px wide
  $foo->file_new_name_body = 'image_resized';
  $foo->image_resize = true;
  $foo->image_convert = gif;
  $foo->image_x = 100;
  $foo->image_ratio_y = true;
  $foo->Process('/home/user/files/');
  if ($foo->processed) {
    echo 'image renamed, resized x=100
          and converted to GIF';
    $foo->Clean();
  } else {
    echo 'error : ' . $foo->error;
  }
}
