Meta Box

Thanks a lot for your solution. It's extremely helpful for other people.

Hi again,

I found the problem for your situation. Your check doesn't run when post is updated, because there's no $GET['post']. In that case, you need to get post ID via $_POST. Here is the code:

function prefix_parent_page_id_check() {
	$parents = get_post_ancestors( prefix_get_post_id() );
	return $parents && 901 == array_pop( $parents );
}

function prefix_get_post_id() {
	if ( isset( $_GET['post'] ) ) {
		return intval( $_GET['post'] );
	}
	if ( isset( $_POST['post_ID'] ) ) {
		return intval( $_POST['post_ID'] );
	}

	return false;
}

Strange, I've just tested with your code and it works. Do you have any "check" code that runs along with (maybe before) the code for Meta Box?

Hi,

The 'std' value works only the first time, e.g. when you haven't save any settings. In your case, if you delete the field value, then the plugin should "remember" your choice - whatever you did - which is the empty value in this case. It would be much confused if it shows the 'std' value, because two things: 1) you wonder where it comes from and 2) you can't actually save an empty value.

Hi,

I've just tried your code with Conditional Logic plugin enabled. Everything works as expected.

Maybe the problem is in the custom JavaScript code, which might breaks the JS code in the plugin(s). Can you please check when exactly the post doesn't save image_select value?

Hi,

You can run a SQL query like this:

DELETE FROM wp_postmeta WHERE meta_key IN ('field1', 'field2');

I'm afraid this is a hard problem. As the file_upload uses Media Library to upload files, all it does is calling the popup, passing the required parameters for the uploader (mime types, file size, etc.) and parsing the returned data. I've just checked the code and couldn't find anything related to the current field, because the uploader doesn't need that. But can you try print_r everything global ($_POST, $_GET, etc.) when filtering? Probably I'm missing something.
