Hi there,

Not too sure what you mean by post pages? Single posts?

For the categories, you can do this:

add_filter( 'get_the_archive_title', 'tu_custom_archive_title' );
function tu_custom_archive_title( $title ) {
    if ( is_category() ) {
        // Your custom ACF field here
    }

    return $title;
}

Yep, single posts.

This code doesn't work, but thanks for directing me to the right way :)

Here is the code for categories (replaces title with advanced custom field):

add_filter( 'single_cat_title', 'tu_custom_archive_title' );
function tu_custom_archive_title( $title ) {
	$term = get_queried_object();
	$mycattitle = get_field('acf_category_title', $term);
	if ( $mycattitle != '' ) {
		return $mycattitle;
	}
	else {
		return $title;
	}
}

Can you help me do the same for single posts?

For single posts, I believe you would use the_title filter.

Let me know if that does it or not :)

Emmm. It works, but it also replaces text of almost all links with my custom field :) Navigation, sidebar, prev and next post links - all have my title instead link text.

I tried to move the code from snippet to hook (before content). Now navigation is fine, but all that after this hook has changed.

Here is the code:

add_filter( 'the_title', 'tu_custom_post_title' );
function tu_custom_post_title( $title ) {
	$term = get_queried_object();
	$myposttitle = get_field('acf_post_title', $term);
	if ( $myposttitle != '' ) {
		return $myposttitle;
	}
	else {
		return $title;
	}
}

Hi there,

Try this instead:

add_filter( 'the_title', 'tu_custom_post_title' );
function tu_custom_post_title( $title ) {
	$term = get_queried_object();
	$myposttitle = get_field('acf_post_title', $term);
	if ( $myposttitle != '' && in_the_loop() ) {
		return $myposttitle;
	}
	else {
		return $title;
	}
}

Better, near perfect ) But prev and next links still have my title. Because they have %title too, I think.

I wonder if adding this would fix it:

add_action( 'generate_after_entry_header', 'tu_remove_title_filter' );
function tu_remove_title_filter() {
    remove_filter( 'the_title', 'tu_custom_post_title' );
}

Bit of a long shot.. Let me know :)

Now everything is perfect ) Thanks!

You're welcome :)
