Add_image_size() in plugin.

    Hi Everybody,

    I’m currently working on my first big plugin. The plugin makes a meta box on a ‘post’ or ‘page’ type page. You can make the settings in the plugins config panel. That’s all working. But… when i get the options from the database the values are right, but i can’t make it work. This is my script:

    function image_attachments_define_image_sizes() {
  add_theme_support('post-thumbnails');
  $image_size_slug = get_option('image-size-slug');
  $image_size_width = get_option('image-size-width');
  $image_size_height = get_option('image-size-height');
  $image_size_crop = get_option('image-size-crop');

  foreach(get_post_types(array('public' => true), 'object') as $label => $keys) {
    for($i = 0; $i <= count($image_size_slug[$label]) - 1; $i++) {
      if($image_size_slug[$label][$i]) {
        $crop = ($image_size_crop[$label][$i] ? true : 0);
        //echo 'add_image_size('. $image_size_slug[$label][$i] .', '. $image_size_width[$label][$i] .', '. $image_size_height[$label][$i] .', '.$crop.')';
        //Gives
        //add_image_size(test, 201, 101, 1);
        //add_image_size(haha, 201, 201, 0);
        //add_image_size(bla, 201, 301, 0);
        add_image_size($image_size_slug[$label][$i], $image_size_width[$label][$i], $image_size_height[$label][$i], $crop);
      }
    }
  }

  //var_dump(get_intermediate_image_sizes());
  /*
    GIVES:
    array(10) {
      [0]=>
      string(9) "thumbnail"
      [1]=>
      string(6) "medium"
      [2]=>
      string(5) "large"
      [3]=>
      string(23) "image-attachments-image"

      string(15) "actueel-preview"
      [7]=>
      string(4) "test"
      [8]=>
      string(4) "haha"
      [9]=>
      string(3) "bla"
    }
  */

}  

add_action('admin_head', 'image_attachments_define_image_sizes');

    The image sizes are being recognized, but i cant find the images with 201*101, 201*201 AND 201*301. Did i choose the wrong add_action?

    add_action('admin_head', 'image_attachments_define_image_sizes');

    Can you please help me?

    Same question here…
    It works when putting add_image_size(…) on functions.php of my theme but I need to do it on a plugin.

    Could someone help us?

    Thanks !

    admin_head is way too late. Do it at init or even better outside of a hook.

    EDIT: dannydehaan, your code specifically should be run inside a hook though (I recommend init) to allow plugins, etc. to register their post types.

    For a generic add_image_size() call though, it’s fine to do it outside of a hooked function.

    EDIT #2: admin_head wouldn’t work anyway as your custom sizes wouldn’t be registered on the front end which would defeat the purpose of registering custom sizes.

    It works for me with admin_init
    Thanks Alex M. !
