I do not want to the_modified_time changed when admin change

Hi driftmagazine,

It is certainly possible to prevent the modified date from changing, however I would discourage you from doing so. If you’re absolutely certain this is what you want to do, then you will want to write a plugin that can utilize the wp_insert_post_data hook. You would want to perform a check for the administrator role using the current_user_can() function, to ensure you’re only targeting the correct thing.

Here’s a sample plugin that could do this: https://gist.github.com/JPry/2e4b074a81d7c8234eb4.

With this sample plugin, note that there’s no distinguishing at all between posts of various types. You may need to expand the logic to cover additional functionality.

Thanks!!
Why would not you recommend it? Is it something I did not think of?

If I want it not to be changed only in the custom post type “bil”?

When you modify the post, but don’t allow the post to know the timestamp of that modification, you’re essentially lying about the post history.

If I want it not to be changed only in the custom post type “bil”?

Add a conditional for post type, which is contained in the $data array:

if ( 'bil' === $data['post_type'] && current_user_can( 'administrator' ) ) {
// ...
}

Thank you so much, unfortunately I do not get the last one to work.
So here I put the last code, maybe completely wrong?

add_filter( 'wp_insert_post_data', 'jpry_filter_insert_post_data', 10, 2 );
function jpry_filter_insert_post_data( $data, $postarr ) {
	// Only strip the modification time for Administrator role.
	if ( current_user_can( 'administrator' ) ) {
		unset( $data['post_modified'] );
	}

	if ( 'bil' === $data['post_type'] && current_user_can( 'administrator' ) ) {
// ...
}

	return $data;
}

You would want the second if statement to entirely replace the first if statement. Take a look at this updated version: https://gist.github.com/JPry/2e4b074a81d7c8234eb4.

Thank you so much!! ??
