Replace get_header() or header.php via plugin

  • How can I replace get_header function or header.php via plugin?

    I installed a child theme and now I’d like to add an html code into header.php

    I used this:

    function myheader( $template ) {
    if ( locate_template( 'header.php' ) != '' ) {
        return untrailingslashit( plugin_dir_path( __FILE__ ) ) . 'header.php';
    }
	return $template;
}
add_filter( 'template_include', 'myheader', 11 );

    It replaces the header and shows only the header and not the full template (the content, sidebar, footer…)

  • The next solution don’t like me but is an options:

    Go to ‘wp-includes/general-template.php’ file and add:

    $templates = apply_filters(‘replace_header’, $templates);
    In the get_header function the final result function is:

    function get_header( $name = null ) {
    /**
     * Fires before the header template file is loaded.
     *
     * The hook allows a specific header template file to be used in place of the
     * default header template file. If your file is called header-new.php,
     * you would specify the filename in the hook as get_header( 'new' ).
     *
     * @since 2.1.0
     * @since 2.8.0 $name parameter added.
     *
     * @param string $name Name of the specific header file to use.
     */
    do_action( 'get_header', $name );

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

    $templates[] = 'header.php';

    $templates = apply_filters('replace_header', $templates); //This is the new line.

    locate_template( $templates, true );
}

    And before that you can:

    function prefix_new_header() {
    return 'header-newtmpl.php';
}
add_filter( 'get_header', 'prefix_new_header' );

    I never modify the source code, I only put here one solution to the problem.
