问题描述：

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?
