# 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.
