WordPress pods模板在get_header之前覆盖标题

I have a pods page using a template, it's working great. But I just need to override the title tag with a pods field containing a value:

    $parcours = pods('parcours' , pods_v_sanitized( 3 , 'url' ) );

    $seo_title = $parcours->field('seo_title'); 

    // Supposed override
    function custom_page_title( $seo_title ) {

    return $seo_title;

    }

    add_filter('pre_get_document_title', 'custom_page_title', 999,1);

    get_header(); ?>

The title does not appear on the page (no override). Of course I made sure that $seo_title actually has a value.

Am I missing something or this is not doable that way?

    You're trying to use the $seo_title variable in the function as global.

    Your code will work, if use like this:

    $parcours = pods('parcours' , pods_v_sanitized( 3 , 'url' ) );
    
    global $seo_title;
    $seo_title = $parcours->field('seo_title'); 
    
    // Supposed override
    function custom_page_title() {
        global $seo_title;
    
        return $seo_title;
    }
    
    add_filter('pre_get_document_title', 'custom_page_title', 999);
    
    get_header(); ?>
    

    With this line global $seo_title; we calling the variable, which is out of function ( $seo_title = $parcours->field('seo_title'); ).
