Page title is missing from title tag on homepage only.

Hi there,

That’s the normal behavior, if you switch to twenty twenty series theme, it should be the same case.

I think a SEO plugin is what you are looking for ??

@ying – Thanks for your reply.

Does anybody know of a way around this without a plugin?

Hi there,

its a WP function that has its own wp_title filter:

https://developer.www.ads-software.com/reference/functions/wp_title/

So you can use a PHP Snippet to change it. For example:

function db_custom_page_title( $title , $separator) {
    // if front page
    if( is_front_page() ){ 
        // set custom title 
        $title = 'your custom title goes here';

    }
    return $title;  
}

add_filter( 'wp_title', 'db_custom_page_title', 10 , 2 );

This checks for a static home page and returns whatever you add to the $title variable.

Should I place that code in the functions.php of the child theme?

Yes – sorry i should have said.
For more info on Adding PHP see here:

https://docs.generatepress.com/article/adding-php/

I have added the snippet to the functions.php of the child theme.
Checked in multiple browsers (also private windows), cleared caches.
Does not work.

Ok – try this snippet instead:

add_filter( 'document_title_parts', 'db_change_doc_title', 15,1 );

function db_change_doc_title( $title ){
    if( is_front_page() ) { 
        $title_parts_array['title'] = 'your custom title goes here';
    }
    return $title_parts_array;
}

Note: this assumes you have a static page set for your home page.

That ony works if I’m logged into WordPress admin in another tab.
When I log out and refresh, it reverts to Site Title only.

Do you have any plugin/server page caching enabled ?

I have literally just turned off caching on the server as you were replying.
Bingo – it works.
Thank you very much for your help David.

Glad to be of help!

Sorry, back again.

Server side caching is still off and browswer caches cleared.

When using this.

add_filter( 'document_title_parts', 'db_change_doc_title', 15,1 );

function db_change_doc_title( $title ){
    if( is_front_page() ) { 
        $title_parts_array['title'] = 'Daves code works';
    }
    return $title_parts_array;
}

The homepage is fine but all other pages in various browsers (logged in or not) show the following error at the top of the page.

Warning: array_filter() expects parameter 1 to be array, null given in /public_html/site/wp-includes/general-template.php on line 1265
Warning: implode(): Invalid arguments passed in /public_html/site/wp-includes/general-template.php on line 1265

Line 1265 has the following.
$title = implode( " $sep ", array_filter( $title ) );

Just an FYI.
PHP version is 7.4.28

Hi @grey4radar

On this line – function db_change_doc_title( $title ){

Can you change $title to $title_parts_array?

So the code is actually pointing to the correct array.

Hi Elvin

That seems to have fixed it.
Thanks for your help.
