1 <?php 2 /** 3 * Twenty Eleven functions and definitions 4 * 5 * Sets up the theme and provides some helper functions. Some helper functions 6 * are used in the theme as custom template tags. Others are attached to action and 7 * filter hooks in WordPress to change core functionality. 8 * 9 * The first function, twentyeleven_setup(), sets up the theme by registering support 10 * for various features in WordPress, such as post thumbnails, navigation menus, and the like. 11 * 12 * When using a child theme you can override certain functions (those wrapped 13 * in a function_exists() call) by defining them first in your child theme's 14 * functions.php file. The child theme's functions.php file is included before 15 * the parent theme's file, so the child theme functions would be used. 16 * 17 * @link https://developer.wordpress.org/themes/basics/theme-functions/ 18 * @link https://developer.wordpress.org/themes/advanced-topics/child-themes/ 19 * 20 * Functions that are not pluggable (not wrapped in function_exists()) are instead attached 21 * to a filter or action hook. The hook can be removed by using remove_action() or 22 * remove_filter() and you can attach your own function to the hook. 23 * 24 * We can remove the parent theme's hook only after it is attached, which means we need to 25 * wait until setting up the child theme: 26 * 27 * <code> 28 * add_action( 'after_setup_theme', 'my_child_theme_setup' ); 29 * function my_child_theme_setup() { 30 * // We are providing our own filter for excerpt_length (or using the unfiltered value). 31 * remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' ); 32 * ... 33 * } 34 * </code> 35 * 36 * For more information on hooks, actions, and filters, see https://developer.wordpress.org/plugins/. 37 * 38 * @package WordPress 39 * @subpackage Twenty_Eleven 40 * @since Twenty Eleven 1.0 41 */ 42 43 // Set the content width based on the theme's design and stylesheet. 44 if ( ! isset( $content_width ) ) { 45 $content_width = 584; 46 } 47 48 /* 49 * Tell WordPress to run twentyeleven_setup() when the 'after_setup_theme' hook is run. 50 */ 51 add_action( 'after_setup_theme', 'twentyeleven_setup' ); 52 53 if ( ! function_exists( 'twentyeleven_setup' ) ) : 54 /** 55 * Set up theme defaults and registers support for various WordPress features. 56 * 57 * Note that this function is hooked into the after_setup_theme hook, which runs 58 * before the init hook.
