Changing the post navigation’s texts

The Customizr WordPress theme comes with default texts for navigation at the bottom of single posts and on post lists pages.

There are some cases where you might need to change those texts, for example if you use custom posts types.

You easily change these without modifying the core code, like often in WordPress, with the help of filters!

Changing the single post navigation texts

Single post navigation title

add_filter( 'tc_singular_nav_title', 'my_nav_title' );
function my_nav_title() {
	return 'My navigation title';
	//or to make it translatable
	// return __('My navigation title' , 'your_translation_domain');
}

If you need to change this nav title only for a particular post type, then use the following code with your custom post type name

add_filter( 'tc_singular_nav_title', 'my_custom_post_type_nav_title' );
function my_custom_post_type_nav_title($default) {
	if ( 'my_custom_post_type' == get_post_type() )
		return 'My custom post type navigation title';
	//return default text in the other cases
	return $default;
}

Single post navigation button’s text (left and right arrow)

In this case, we need to filter two values : previous and next button’s text.

We can do that with the same callback function using a switch statement on the current filter’s value .

add_filter( 'tc_singular_nav_next_text' , 'my_nav_buttons_text' );
add_filter( 'tc_singular_nav_previous_text' , 'my_nav_buttons_text' );

function my_nav_buttons_text() {
  switch ( current_filter() ) {
    case 'tc_singular_nav_previous_text':
      return 'previous post &larr;'; // <= your custom text here
    case 'tc_singular_nav_next_text':
      return '&rarr; next post'; // <= your custom text here
  }
}

Changing the post list navigation texts

You can also use the post type conditional statement for the post list.

Post list navigation title

This time, we use the ‘tc_list_nav_title’ filter

add_filter( 'tc_list_nav_title', 'my_post_list_nav_title' );
function my_post_list_nav_title() {
	return 'My post list navigation title';
}

Post list navigation button’s text

Same as before, we use one single callback function to filter both values :

add_filter( 'tc_list_nav_next_text' , 'my_list_nav_buttons_text');
add_filter( 'tc_list_nav_previous_text' , 'my_list_nav_buttons_text');

function my_list_nav_buttons_text() {
    switch ( current_filter() ) {
        case 'tc_list_nav_next_text':
            $text = '<span class="meta-nav">&larr;</span> old posts';
            break;
        
        case 'tc_list_nav_previous_text':
            $text = 'new posts <span class="meta-nav">&rarr;</span>';
            break;
    }
    return $text;
}
