无法将自定义元框添加到自定义帖子类型 _WordPress开发

试图将自定义元框添加到wordpress中的自定义帖子类型, 似乎没有任何效果。
当我从教程中复制并粘贴整个代码片段时, 它就可以正常工作。当我尝试将其添加到已经完成的自定义帖子类型中时, 我什么也没得到。页面不会中断, 自定义元框不会显示。在我拔头发时, 希望能有所帮助。
在这一点上, 我只希望将这些东西显示在后期编辑界面中！

// Register Custom Post Type function generate_shows() {$labels = array( 'name'=> _x( 'Shows', 'Post Type General Name', 'text_domain' ), 'singular_name'=> _x( 'Show', 'Post Type Singular Name', 'text_domain' ), 'menu_name'=> __( 'Shows', 'text_domain' ), 'parent_item_colon'=> __( 'Parent Item:', 'text_domain' ), 'all_items'=> __( 'All Shows', 'text_domain' ), 'view_item'=> __( 'View Item', 'text_domain' ), 'add_new_item'=> __( 'Add New Show', 'text_domain' ), 'add_new'=> __( 'Add New', 'text_domain' ), 'edit_item'=> __( 'Edit Item', 'text_domain' ), 'update_item'=> __( 'Update Item', 'text_domain' ), 'search_items'=> __( 'Search Shows', 'text_domain' ), 'not_found'=> __( 'Not found', 'text_domain' ), 'not_found_in_trash'=> __( 'Not found in Trash', 'text_domain' ) ); $args = array( 'label'=> __( 'enk_show', 'text_domain' ), 'description'=> __( 'An individual ENK Shows', 'text_domain' ), 'labels'=> $labels, 'supports'=> array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'revisions', 'custom-fields', 'page-attributes', 'post-formats', ), 'taxonomies'=> array( 'category', 'post_tag' ), 'hierarchical'=> true, 'rewrite'=> array( 'slug' => 'shows', 'with_front' => false ), 'public'=> true, 'show_ui'=> true, 'show_in_menu'=> true, 'show_in_nav_menus'=> true, 'show_in_admin_bar'=> true, 'menu_position'=> 5, 'can_export'=> true, 'has_archive'=> true, 'exclude_from_search' => false, 'publicly_queryable'=> true, 'register_meta_box_cb' => 'add_enk_metaboxes', 'capability_type'=> 'post' ); register_post_type( 'enk_show', $args ); }// Hook into the 'init' action add_action( 'init', 'generate_shows', 0 ); // Add the Events Meta Boxes function add_enk_metaboxes() { add_meta_box('wpt_events_location', 'Event Location', 'wpt_events_location', 'events', 'side', 'default'); }

add_action('add_meta_boxes', 'add_enk_metaboxes')

你还需要为该框的html创建一个函数
例如

function wpt_events_location($post) { // your 3rd parameter is the function callback $metavalue= http://www.srcmini.com/get_post_meta($post-> id,'metakey', true); echo '< input type="text" name="formfield" value="'.$metavalue.'" > '; }

以及要保存的回调

function save_post_meta($post_id){ if($_POST['formfield']) update_post_meta($post_id, 'metakey', $_POST['formfield']; }add_action('save_post', 'save_post_meta');

我记得该抄本有一些很好的例子, 包括现时和OOP风格。 PS注意上面没有安全性, 你仍然需要清理值等。
#2你必须尝试以下方法：
首先, 为你的帖子类型创建一个元框

< ?php // Add the Events Meta Boxes function add_enk_metaboxes($post) { add_meta_box('wpt_events_location', 'Event Location', 'wpt_events_location', 'events', 'side', 'default'); } add_action('add_meta_boxes', 'add_enk_metaboxes');

【无法将自定义元框添加到自定义帖子类型】然后为元字段创建一个函数：

function wpt_events_location($post){$txtEventLocation = get_post_meta($post-> ID, 'txtEventLocation', true); ?> < table width="100%" border="0" cellspacing="4" cellpadding="0"> < tr> < td width="16%"> < strong> Event Location:< /strong> < /td> < td width="84%"> < input type="text" name="txtEventLocation" id="txtEventLocation" size="72%" value="http://www.srcmini.com/< ?php echo $txtEventLocation ?>" /> < /td> < /tr> < /table> < ?php }

然后保存元字段数据：

add_action('save_post', 'save_event_location'); function save_event_location(){ global $post; $txtEventLocation = $_POST['txtEventLocation']; update_post_meta( $post-> ID, 'txtEventLocation', $txtEventLocation); }?>

希望你找到解决方案。
#3代码将帮助你在Wordpress中创建自定义metabox

< ?phpadd_action( 'add_meta_boxes', 'add_custom_metaboxes' ); // Add the Events Meta Boxesfunction add_custom_metaboxes() { //add_meta_box('wpt_events_date', 'Event Date', 'wpt_events_date', 'wpstore', 'side', 'default'); add_meta_box('wpt_events_location', 'Address Location', 'wpt_events_location', 'post_tyme_name', 'normal', 'high'); }// The Event Location Metaboxfunction wpt_events_location() { global $post; // Noncename needed to verify where the data originated echo '< input type="hidden" name="eventmeta_noncename" id="eventmeta_noncename" value="' . wp_create_nonce( plugin_basename(__FILE__) ) . '" /> '; // Get the location data if its already been entered $addressline1 = get_post_meta($post-> ID, '_addressline1', true); $addressline2 = get_post_meta($post-> ID, '_addressline2', true); // Echo out the field echo '< p> Address Line 1:< /p> '; echo '< input type="text" name="_addressline1" value="' . $addressline1. '" class="widefat" /> '; echo '< p> Address Line 2< /p> '; echo '< input type="text" name="_addressline2" value="' . $addressline2. '" class="widefat" /> '; }// Save the Metabox Datafunction wpt_save_events_meta($post_id, $post) {// verify this came from the our screen and with proper authorization, // because save_post can be triggered at other times if ( !wp_verify_nonce( $_POST['eventmeta_noncename'], plugin_basename(__FILE__) )) { return $post-> ID; }// Is the user allowed to edit the post or page? if ( !current_user_can( 'edit_post', $post-> ID )) return $post-> ID; // OK, we're authenticated: we need to find and save the data // We'll put it into an array to make it easier to loop though.$events_meta['_addressline1'] = $_POST['_addressline1']; $events_meta['_addressline2'] = $_POST['_addressline2']; // Add values of $events_meta as custom fieldsforeach ($events_meta as $key => $value) { // Cycle through the $events_meta array! if( $post-> post_type == 'revision' ) return; // Don't store custom data twice $value = http://www.srcmini.com/implode(', ', (array)$value); // If $value is an array, make it a CSV (unlikely) if(get_post_meta($post-> ID, $key, FALSE)) { // If the custom field already has a value update_post_meta($post-> ID, $key, $value); } else { // If the custom field doesn't have a value add_post_meta($post-> ID, $key, $value); } if(!$value) delete_post_meta($post-> ID, $key); // Delete if blank }}add_action('save_post', 'wpt_save_events_meta', 1, 2); // save the custom fields
