srcmini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', $args );
}
// Hook into the 'init' action
add_action( 'init', 'generate_shows', 0 );
// Add the Events Meta Boxes
function add_enk_metaboxes() {
add_meta_box('wpt_events_location', 'Event Location', 'wpt_events_location', 'events', 'side', 'default');
}
#1
add_action('add_meta_boxes', 'add_enk_metaboxes')
你还需要为该框的html创建一个函数
例如
function wpt_events_location($post) { // your 3rd parameter is the function callback
$metavalue= get_post_meta($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。

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($post) {
add_meta_box('wpt_events_location', 'Event Location', 'wpt_events_location', 'events', 'side', 'default');
}
add_action('add_meta_boxes', 'add_enk_metaboxes');
然后为元字段创建一个函数：
function wpt_events_location($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="<?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。

代码将帮助你在Wordpress中创建自定义metabox
<?php
add_action( 'add_meta_boxes', 'add_custom_metaboxes' );
// Add the Events Meta Boxes
function 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 Metabox
function 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="' . $addressline2 . '" class="widefat" />';
}
// Save the Metabox Data
function wpt_save_events_meta($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 $events_meta as custom fields
foreach ($events_meta as $key => $value) { // Cycle through the $events_meta array!
if( $post->post_type == 'revision' ) return; // Don't store custom data twice
$value = implode(', ', (array)$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
