我有一个名为room\\u type的post\\u类型和一个分类room\\u设施。我想要他们之间的关系。此外，我想为每个关系room\\u类型和room\\u设施添加一个值。前端如下所示：

该值使用meta\\u key \\u room\\u facility\\u key\\u存储在Posteta中，其中是room\\u facility的id和room\\u type的post\\u id。我认为这是将价值与room\\u类型和room\\u设施联系起来的最简单方法，对吗？

您可以看到我得到了存储在数据库中的值。问题是要拯救他们。这是我的密码。

要添加元盒，请执行以下操作：

function room_facility_custom_meta() {
    add_meta_box( \'room_facility_meta\', __( \'Meta Box \', \'room_facility-textdomain\' ), \'room_facility_meta_callback\', \'room_type\' );
}
add_action( \'add_meta_boxes\', \'room_facility_custom_meta\' );

我的回调函数

function room_facility_meta_callback( $post ) {
    //nonce_field
    wp_nonce_field( basename( __FILE__ ), \'room_facility_nonce\' );

    $tax = "room_facility";
    $term_facilities = get_terms( $tax, array(\'hide_empty\' => false));
    $term_checked_facilities= wp_get_post_terms($post->ID, $tax);

    foreach($term_facilities as $term){

        $room_facility_id = $term->term_id;
        /* the meta_key for postmeta, note there is the room_facility included, 
         * since there should be a relationship between post_id (in this case from taxonomy "room_type") 
         * and "room_facility" 
         */
        $meta_key = "_room_facility_key_".$room_facility_id;
        //value from the postmeta
        $room_facility_value = get_post_meta($post->ID, $meta_key);

    ?>
        <div class="row">
                <label for="checkbox_<?php echo $room_facility_id ?>">
                    <input type="checkbox" name="checkbox_<?php echo $room_facility_id ?>" id="checkbox_<?php echo $room_facility_id ?>"  <?php checked( myArrayContainsWord($term_checked_facilities, $term->term_id)); ?> />
                    <?php _e( $term->name, \'prfx-textdomain\' )?>
                </label>
                <input type="text" name="text_<?php echo $room_facility_id ?>" id="text_<?php echo $room_facility_id ?>" value="<?php if ( !empty ( $room_facility_value[0] ) ){ echo $room_facility_value[0]; }?>" />
        </div>
    <?php
    } //end foreach
}

我的保存功能

    function room_facility_meta_save( $post_id ) 
    {
          // 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[\'room_facility_nonce\'], plugin_basename(__FILE__) )) { <-- THIS DIDN\'T WORK
           if(! isset( $_POST[\'room_facility_nonce\'] )){
                return $post_id;
              }

           // Verify if this is an auto save routine. If it is our form has not been submitted, so we dont want
          // to do anything


   if ( defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE ) 
        return $post_id;


          //wp_set_object_terms( 742, array(211), \'room_facility\');
          $taxonomy = "room_facility";
          $term_facilities = get_terms( $taxonomy, array(\'hide_empty\' => false));

          foreach ($term_facilities as $tax => $term)
          {
            $room_facility_id = $term->term_id;

            /* the meta_key for postmeta, note there is the room_facility included, 
             * since there should be a relationship between post_id (in this case from taxonomy "room_type") 
             * and "room_facility" 
             */
            $meta_key = "_room_facility_key_".$room_facility_id;

            //update postmeta room_facility_key_<ID>  
            if( isset( $_POST[ "text_".$room_facility_id] ) ) {
                update_post_meta( $post_id, $meta_key, sanitize_text_field( $_POST[ "text_".$room_facility_id] ) );
            }

            //set wp_term_relationships for room_type and room_facility
            if( isset( $_POST[ \'checkbox_\'.$room_facility_id ] ) ) 
            {
                //wp_set_post_terms( $post_id, $term, $taxonomy); <-- WRONG function
               $error_obj = wp_set_object_terms( $post_id, (int)$term->term_id , $taxonomy);
            } /*else {
                wp_set_post_terms( $post_id, $term, $taxonomy);
            }*/
          }
}
add_action( \'save_post\', \'room_facility_meta_save\' );

我不确定是否调用了save函数，因为当我执行

echo \'<script>alert("test")</script>\';

什么都没发生。。。

我知道我发布了很多代码，但我真的不知道为什么它不起作用。如果您有问题，请随时提问。
