    Hey, I use the image ACF field with validation turned on, and now I need to check it’s size. But that image field returns only the attachment ID. So first of all I need to get image URL and I use wp_get_attachment_image_src function for that. But the problem is that I can’t get anything from that function. Code I am trying to use is:

    $img_src = wp_get_attachment_image_src($value, ‘full’).0;
    return $img_src;

  • Not sure if you figured this out yourself, but here is how I did it, probably a little messy but it works.

    $maxsize = 1000000;
if( $_FILES ) {
    
    if( $_FILES['acf']['size']['field_key'] > $maxsize ) {
        
         return 'Featured image is too large. Must be smaller than 1MB';
        
    }
    
}
