I have created below function to hide page title . But when i execute it it also hide
menu name also. Can any one please help on that it will be highly appreciated.

function wsits_post_page_title( $title ) {

              if( is_admin())



        return $title;



    $selected_type  =   get_option('wsits_page_show_hide');



    if(!is_array($selected_type)) return $title;



    if ( ( in_array(get_post_type(), $selected_type ) ) &&  get_option('wsits_page_show_hide') ) 

    {

        $title = '';

    }

    return $title;

}

add_filter( 'the_title', array($this, 'wsits_post_page_title') );

Nikola is correct:

Because menu items also have titles and they need to be filtered :).

To make this only call in the posts, and not in menus, you can add a check for in_the_loop() - if it is true, you're in a post.

So change the first line in the function to:

if( is_admin() || !in_the_loop() )

and all should be well.

You can do something like that :

In your function.php :

add_filter( 'the_title', 'ze_title');

function ze_title($a) {

    global $dontTouch;

    if(!$dontTouch && !is_admin())

        $a = someChange($a);

    return $a;

}

In your template :

$dontTouch = 1;

wp_nav_menu( array('menu' => 'MyMenu') );

$dontTouch = 0;

It's a bit of a hack but you can solve this by adding your action to loop_start.

function make_custom_title( $title, $id ) {

    // Your Code Here

}



function set_custom_title() {

   add_filter( 'the_title', 'make_custom_title', 10, 2 );

}



add_action( 'loop_start', 'set_custom_title' );

By embedding the_title filter inside of a loop_start action, we avoid overwriting the menu title attributes.

Posting this answer because it was the search result I ended up clicking on while searching about targeting the filter hook the_title while ignoring the filter effect for navigation items.

I was working on a section in a theme which I wanted to add buttons to the page title within the heading one tag.

It looked similar to this:

<?php echo '<h1>' . apply_filters( 'the_title', $post->post_title ) . '</h1>'.PHP_EOL; ?>

I was then "hooking in" like this:

add_filter( 'the_title', 'my_callback_function' );

However, the above targets literally everything which calls the_title filter hook, and this includes navigation items.

I changed the filter hook definition like this:

<?php echo '<h1>' . apply_filters( 'the_title', $post->post_title, $post->ID, true ) . '</h1>'.PHP_EOL; ?>

Pretty much every call to the_title filter passes parameter 1 as the $post->post_title and parameter 2 as the $post->ID. Search the WordPress core code for apply_filters( 'the_title'* and you'll see for yourself.

So I decided to add a third parameter for situations where I want to target specific items which call the_title filter. This way, I can still receive the benefit of all callbacks which apply to the_title filter hook by default, while also having the ability to semi-uniquely target items that use the_title filter hook with the third parameter.

It's a simple boolean parameter:

/**

 * @param String $title

 * @param Int $object_id

 * @param bool $theme

 *

 * @return mixed

 */

function filter_the_title( String $title = null, Int $object_id = null, Bool $theme = false ) {



    if( ! $object_id ){

        return $title;

    }



    if( ! $theme ){

        return $title;

    }



    // your code here...



    return $title;



}



add_filter( 'the_title', 'filter_the_title', 10, 3 );

Label the variables however you want. This is what worked for me, and it does exactly what I need it to do. This answer may not be 100% relevant to the question asked, but this is where I arrived while searching to solve this problem. Hope this helps someone in a similar situation.

The global $dontTouch; solution didn't work for me for some reason. So I simply removed the filter around the menu thus in header.php:

remove_filter( 'the_title', 'change_title' );

get_template_part( 'template-parts/navigation/navigation', 'top' ); 

add_filter( 'the_title', 'change_title' );

And all is well.
