如何在子主题上编辑函数（）

主题WordPress网站开发IT知识问答函数php子主题编辑函数

我在function.php的主要主题上具有此函数：

if(!function_exists('eagle_booking_append_booking_button_menu') & & eagle_booking_get_option('eagle_booking_header_button')):add_filter( 'wp_nav_menu_items', 'eagle_booking_append_booking_button_menu', 12, 2 ); function eagle_booking_append_booking_button_menu ( $items, $args ) {// BUTTON ACTION BASED ON BOOKING SYSTEM if (eagle_booking_get_option('booking_type') == 'builtin' ) { $eagle_booking_button_action= eagle_booking_search_page(); } elseif (eagle_booking_get_option('booking_type') == 'custom') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_custom_action'); } elseif (eagle_booking_get_option('booking_type') == 'booking') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_booking_action'); } elseif (eagle_booking_get_option('booking_type') == 'airbnb') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_airbnb_action'); } elseif (eagle_booking_get_option('booking_type') == 'tripadvisor') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_tripadvisor_action'); }if ((eagle_booking_get_option('eagle_booking_header_button')) & & ( $args-> theme_location == 'zante_main_menu' )) { $items .= '< li class="menu_button"> < a href="'.$eagle_booking_button_action.'" class="button"> < i class="fa fa-calendar"> < /i> '.esc_html__('BOOK ONLINE', 'eagle-booking').'< /a> < /li> '; }return $items; }endif;

我想编辑函数的最后一部分, 例如：
if ((eagle_booking_get_option('eagle_booking_header_button')) & & ( $args-> theme_location == 'zante_main_menu' )) { $mdpLinkButton = "/contact-us/"; $items .= '< li class="menu_button"> < a href="'.$mdpLinkButton.'" class="button"> < i class="fa fa-calendar"> < /i> '.esc_html__('CONTACT US', 'eagle-booking').'< /a> < /li> '; }

我做了自定义主题。但是我应该在那个function.php中做什么？覆盖上面还是什么？
#1为此, 你需要删除父主题应用的过滤器, 然后在子主题中再次定义它, 如下所示：
子主题functions.php
add_action( 'init', 'remove_my_action'); function remove_my_action() { remove_filter( 'wp_nav_menu_items', 'eagle_booking_append_booking_button_menu', 12 ); }add_filter( 'wp_nav_menu_items', 'child_eagle_booking_append_booking_button_menu', 12, 2 ); function child_eagle_booking_append_booking_button_menu ( $items, $args ) {// BUTTON ACTION BASED ON BOOKING SYSTEM if (eagle_booking_get_option('booking_type') == 'builtin' ) { $eagle_booking_button_action= eagle_booking_search_page(); } elseif (eagle_booking_get_option('booking_type') == 'custom') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_custom_action'); } elseif (eagle_booking_get_option('booking_type') == 'booking') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_booking_action'); } elseif (eagle_booking_get_option('booking_type') == 'airbnb') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_airbnb_action'); } elseif (eagle_booking_get_option('booking_type') == 'tripadvisor') { $eagle_booking_button_action = eagle_booking_get_option('booking_type_tripadvisor_action'); }if ((eagle_booking_get_option('eagle_booking_header_button')) & & ( $args-> theme_location == 'zante_main_menu' )) { $mdpLinkButton = "/contact-us/"; $items .= '< li class="menu_button"> < a href="'.$mdpLinkButton.'" class="button"> < i class="fa fa-calendar"> < /i> '.esc_html__('CONTACT US', 'eagle-booking').'< /a> < /li> '; }return $items; }

#2【如何在子主题上编辑函数（）】子主题functions.php在父主题functions.php之前加载, 因此如果父主题函数具有检查(！function_exists()), 则可以在子functions.php中使用相同的函数名称覆盖它。
