Construction
The entire plugin is contained in a class definition, and is initialized through the __construct() function.
1 2 3 4 5 6 | public function __construct() { add_action( ‘admin_init’, array( $this, ‘wp_link_pages_extended_admin_init’ ) ); add_filter( ‘query_vars’, array( $this, ‘wp_link_pages_extended_parameter_queryvars’ ) ); add_action( ‘the_post’, array( $this, ‘wp_link_pages_extended_the_post’ ), 0 ); } |
In order for the viewall URL parameter to be returned, it needed to be defined as a valid query parameter.
1 2 3 4 5 | function wp_link_pages_extended_parameter_queryvars( $queryvars ) { $queryvars[] = ‘viewall’; return( $queryvars ); } |
Internationalization
Internationalization was performed as a demonstration of the power of WordPress internationalization.
1 | load_plugin_textdomain( ‘wp-link-pages-extended’, false, dirname( plugin_basename( __FILE__ ) ) ); |
There are only eight words or phrases that need to be translated: “First”, “Last”, “Next”, “of”, “Page”, “Prev”, “View All” and “View Pages”.
Notes
- No attempt was made to style the links so they retain the parent theme styling.
- There is an error on the
wp_link_pagesreference page that had my head whirling for several minutes wondering where the separators were during testing before I finally realized it. The reference page lists the array element as being spelled ‘Seperator’ while the actual array element is correctly spelled in the example as ‘separator’.
