Custom Field does not respect Image Size Selection

Hi,

Well, I am not sure if that is doable with custom field attachments, but we can try something.

add_filter('asp_results', 'asp_get_attachments_size', 10, 1);
function asp_get_attachments_size($results) {
	$field = 'my_custom_field';
	$size = 'thumbnail';

	foreach ( $results as $k => &$r ) {
		$val = get_post_meta( $r->id, $field, true );
		if ( $val != null && $val != "" ) {
			if ( is_numeric($val) ) {
				$imx = wp_get_attachment_image_src(
					$val, $size, false
				);
				if ( !is_wp_error($imx) && $imx !== false && isset($imx[0]) )
					$r->image = $imx[0];
			} else if ( $val != "" ) {
				$r->image = $val;
			}
		}
	}
	return results;
}

Try adding this code to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.

If this does work, then I can try implementing a permanent solution for the upcoming release.

Ah, thought it was working but still seems weird I think.

The size might be named differently. I am guessing the “thumbnail” as the default, but it is very much possible it is different from that. Try checking the registered image sizes list, you can see it here: https://i.imgur.com/b0WdNIs.png
Then change the $size variable accordingly. Also, don’t forget to change the $field variable as well.
