如何在wordpress中更新更新后的元数据上保存多个复选框（） _WordPress开发

我有多个复选框, 我想保存该复选框并在update_post_meta中对其进行更新, 以便下次用户编辑帖子时, 他会知道已经选中了哪些复选框。我不知道我在哪里弄错了。这是我的代码：

add_action( 'add_meta_boxes', 'add_custom_box' ); function add_custom_box( $post ) {add_meta_box( 'Meta Box', // ID, should be a string 'Music', // Meta Box Title 'music_meta_box', // Your call back function, this is where your form field will go 'post', // The post type you want this to show up on, can be post, page, or custom post type 'side', // The placement of your meta box, can be normal or side 'core' // The priority in which this will be displayed ); }function music_meta_box( $post ) {// Get post meta value using the key from our save function in the second paramater. $custom_meta = get_post_meta($post-> ID, 'custom-meta-box', true); ?> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/huge" < ?php if(isset($_POST['custom-meta-box']['huge'])) echo 'checked="checked"'; ?> /> Huge < br> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/house" < ?php if(isset($_POST['custom-meta-box']['house'])) echo 'checked="checked"'; ?> /> House < br> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/techno" < ?php if(isset($_POST['custom-meta-box']['techno'])) echo 'checked="checked"'; ?> /> Techno < br> < ?php} add_action( 'save_post', 'save_music_meta_box' ); function save_music_meta_box(){global $post; // Get our form field if(isset( $_POST['custom-meta-box'] )) :$custom = $_POST['custom-meta-box']; // Update post metaforeach($ids as $id){ update_post_meta($id, '_custom-meta-box', $custom[$id]); wp_set_object_terms( $id, $custom[$id], 'Music' ); }endif; }

请帮忙
#1试试这个逻辑：

function music_meta_box( $post ) { // Get post meta value using the key from our save function in the second paramater. $custom_meta = get_post_meta($post-> ID, '_custom-meta-box', true); ?> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/huge" < ?php echo (in_array('huge', $custom_meta)) ? 'checked="checked"' : ''; ?> /> Huge < br> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/house" < ?php echo (in_array('house', $custom_meta)) ? 'checked="checked"' : ''; ?> /> House < br> < input type="checkbox" name="custom-meta-box[]" value="http://www.srcmini.com/techno" < ?php echo (in_array('techno', $custom_meta)) ? 'checked="checked"' : ''; ?> /> Techno< br> < ?php } add_action( 'save_post', 'save_music_meta_box' ); function save_music_meta_box() {global $post; // Get our form field if(isset( $_POST['custom-meta-box'] )) { $custom = $_POST['custom-meta-box']; $old_meta = get_post_meta($post-> ID, '_custom-meta-box', true); // Update post meta if(!empty($old_meta)){ update_post_meta($post-> ID, '_custom-meta-box', $custom); } else { add_post_meta($post-> ID, '_custom-meta-box', $custom, true); } } }
