proposal: make specialized header name available inside header.php

[Jules Colle]

You can call get_header() with an extra argument. For example: get_header('wp-signup'). This allows theme authors to create a specific header: header-wp-signup.php.

But it would be nice to also this name inside the regular header.php file, to allow for a small tweak instead of completely duplicating the header.php file.

My proposal is to modify this function in wp-includes/general-template.php line 27:

<?php
function get_header( $name = null, $args = array() ) {
        /**
         * Fires before the header template file is loaded.
         *
         * @since 2.1.0
         * @since 2.8.0 The `$name` parameter was added.
         * @since 5.5.0 The `$args` parameter was added.
         *
         * @param string|null $name Name of the specific header file to use. Null for the default header.
         * @param array       $args Additional arguments passed to the header template.
         */
        do_action( 'get_header', $name, $args );

        $templates = array();
        $name      = (string) $name;
        if ( '' !== $name ) {
                $templates[] = "header-{$name}.php";
        }

        $templates[] = 'header.php';

        if ( ! locate_template( $templates, true, true, $args ) ) {
                return false;
        }
}

We could call locate_template like this:

<?php
locate_template( $templates, true, true, array_merge($args,[ '__name' => $name ]) )

Then, inside header.php it would be possible to access the header name like this:

$header_name = $args['__name']

Hi there, welcome back to WordPress Trac! Thanks for the ticket.

If I understand correctly, you'd like to use header.php instead of header-wp-signup.php, and just pass an additional parameter to it to make some tweaks?

In that case, you can utilize the $args parameter added in [48370] / #21676.

If you call get_header() like this:

get_header( null, array( '__name' => 'wp-signup' ) );

you'll have access to $args['__name'] in header.php. Would that accomplish the task?

[Jules Colle]

Thanks for the quick reply Sergey. Not really. The proposed change is aimed at default wordpress pages, like wp-activate.php and wp-signup.php, these files are calling resp. get_header( 'wp-activate' ); and get_header( 'wp-signup' );

Now, there seems to be no way to detect this parameter inside header.php (without changing the core file.)

Actually, I just realized that the 2 pages mentioned are about the only pages where this applies... So the severity of this ticket can be lowered even more if you want.

Ah, thanks for the clarification, it makes more sense to me now :)
