I am trying to overwrite the <title> tag of a page using a Wordpress plugin.
I don't want to change the theme's code. I just wanna force the theme to change some page titles via the plugin.
The theme uses add_theme_support( 'title-tag' ). Note that the use of wp_title is now deprecated.
Your problem is that you can not use wp_title() in the theme if the theme already supports title-tag. The <head> of your theme should look like this:
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<?php wp_head(); ?>
</head>
The filter and title-tag support:
add_action( 'after_setup_theme', 'my_theme_functions' );
function my_theme_functions() {
add_theme_support( 'title-tag' );
}
add_filter( 'wp_title', 'custom_titles', 10, 2 );
function custom_titles( $title, $sep ) {
//set custom title here
$title = "Some other title" . $title;;
return $title;
}
If you do this, it will work perfectly.
