如何从 Wordpress 中的 functions.php 中删除默认元标题？

Question

Ok, so I have added my own title in the header.php

<title>  
  <?php 
    if (!(is_front_page())) {
      wp_title('', true,''); ?>  (<?php the_time( 'Y/m/d' ); ?>)- 
    <?php }
  echo get_bloginfo( 'name' ); ?>  
</title>

It works great.

The problem is that when I click on View Source, I see two title codes.

First one is my title that I manually added to header.php

And the second one is the default Wordpress title.

My question is, where do I need to modify (probably in the functions.php?) to remove the default Wordpress title?

Answer 1

Might be able to use this in your functions.php based on: wp-includes/default-filters.php

remove_action( 'wp_head', '_wp_render_title_tag' );

UPDATE

Based on your theme I recommend you remove your custom title from the header, remove the above remove_action i previously suggested and use the below solution in your functions.php. this will hook into the existing theme title and modify its value using your custom title code:

add_filter('wp_title', function($default_title){
    $title = '';

    if (!is_front_page()) {
        $title .= wp_title('', false,'') .' '. get_the_time( 'Y/m/d' ) . '- ';
    }

    $title .= get_bloginfo( 'name' );

    return $title;
});

Answer 2

Here's the working sulution. Just paste the below code to your functions.php:

remove_action( 'wp_head', '_wp_render_title_tag', 1 );
