editing wordpress custom header php file - php

Question

I am using an open source theme for a wordpress website. While most of the site is done, I am having trouble adding a second slogan area to our site.
Additionally, I am attempting to modify customer_header.php to make the front page showcase appear on all pages as well.
Currently the home page is the only page displaying the header showcase and only has two lines of text. The following is the php:
<?php
/**
* Sample implementation of the Custom Header feature.
*
* #link http://codex.wordpress.org/Custom_Headers
*
* #package refur
*/
class refur_custom_header {
/**
* A reference to an instance of this class.
*
* #var object
*/
private static $instance = null;
/**
* Default header settings array
*
* #var array
*/
public $default_settings = array();
/**
* Holder for active showcase trigger
*
* #var bool
*/
public $is_showcase = null;
function __construct() {
add_filter( 'body_class', array( $this, 'add_body_classes' ) );
add_action( 'after_setup_theme', array( $this, 'custom_header_setup' ) );
add_action( 'refur_header_showcase', array( $this, 'public_callback' ) );
add_action( 'customize_register', array( $this, 'header_settings' ) );

'header_slogan_title' => __( 'Your Awesome Blog', 'refur' ),
'header_slogan_text' => __( 'Just a few words why you blog is so awesome', 'refur' ),
'header_button_text' => __( 'Call to action', 'refur' ),
'header_button_url' => '#'
);
}

Answer 1

For part one: I'm not going to write all the code for you, but you can basically just find all the places in that file where you find header_slogan_title, header_slogan_text, and header_button_text and duplicate them judiciously.
For part two: you're going to want to hack this code in the file you linked to in your question:
/**
* Is showcase area visible on current page
*
* #return boolean
*/
public function is_showcase() {
if ( null !== $this->is_showcase ) {
return $this->is_showcase;
}
$this->is_showcase = ( is_front_page() && ! is_paged() ) ? true : false;
return $this->is_showcase;
}
Most likely you will want to change
$this->is_showcase = ( is_front_page() && ! is_paged() ) ? true : false;
to
$this->is_showcase = is_page();
or some other combination of template tags that produces true for the pages you want it to show for and false for the others.
