Question

我有一个针对某些自定义帖子类型的自定义元框，并且元框中的其中一个字段就像这里的下拉菜单！这是我的代码

add_action('add_meta_boxes','mind_scholar_meta_box');
function mind_scholar_meta_box()
{
   add_meta_box('ms_meta_box','Info Meta Box','mind_scholar_meta_fields','team','normal','high');
}
function mind_scholar_meta_fields()
{

   global $post;
   $field=get_post_meta($post->ID,'mind_scholar_key',true);
   $select=get_post_meta($post->ID,'mind_scholar_select_key',true);
   ?>
   <html>
   <body>
   <table>
      <tr>
         <td weidth="50%">
            School Name:
         </td>
         <td weidth="50%">
            <input type="text" name="first" value="<?php echo $field ?>">
         </td>
      </tr>
      <tr>
         <td width="50%">
            Stars Rating:
         </td>
         <td>
            <select>
               <option value="star_1" <?php selected( $select, 'star_1' ); ?>>Star 1</option>
               <option value="star_2" <?php selected( $select, 'star_2' ); ?>>Star 2</option>
               <option value="star_3" <?php selected( $select, 'star_3' ); ?>>Star 3</option>
               <option value="star_4" <?php selected( $select, 'star_4' ); ?>>Star 4</option>
               <option value="star_5" <?php selected( $select, 'star_5' ); ?>>Star 5</option>
            </select>
         </td>
      </tr>
   </table>
   </body>
   </html>
   <?php
}
add_action('save_post','save_posts');
function save_posts()
{
   global $post;
   $ms_field=$_POST['first'];
   $ms_field_select=$_POST[''];

   update_post_meta($post->ID,'mind_scholar_key',$ms_field);
   update_post_meta($post->ID,'mind_scholar_select_key',$ms_field_select);

}

不幸的是，我的下拉菜单未保存在我的CPT中！有人可以帮忙吗？ :(

复制此代码并使用

add_action('add_meta_boxes','mind_scholar_meta_box'); function mind_scholar_meta_box() {    add_meta_box('ms_meta_box','Info Meta Box','mind_scholar_meta_fields','team','normal','high'); } function mind_scholar_meta_fields() {

   global $post;    $field=get_post_meta($post->ID,'mind_scholar_key',true);    $select=get_post_meta($post->ID,'mind_scholar_select_key',true);    ?> <html>    <body>    <table>
      <tr>
         <td weidth="50%">
            School Name:
         </td>
         <td weidth="50%">
            <input type="text" name="first" value="<?php echo $field ?>">
         </td>
      </tr>
      <tr>
         <td width="50%">
            Stars Rating:
         </td>
         <td>
            <select name='second_select'>
               <option value="star_1" <?php selected( $select, 'star_1' ); ?>>Star 1</option>
               <option value="star_2" <?php selected( $select, 'star_2' ); ?>>Star 2</option>
               <option value="star_3" <?php selected( $select, 'star_3' ); ?>>Star 3</option>
               <option value="star_4" <?php selected( $select, 'star_4' ); ?>>Star 4</option>
               <option value="star_5" <?php selected( $select, 'star_5' ); ?>>Star 5</option>
            </select>
         </td>
      </tr>    </table>    </body>    </html>    <?php } add_action('save_post','save_posts'); function save_posts() {    global $post;    $ms_field=$_POST['first'];    $ms_field_select=$_POST['second_select'];

   update_post_meta($post->ID,'mind_scholar_key',$ms_field);    update_post_meta($post->ID,'mind_scholar_select_key',$ms_field_select);

}

Answer 2

您完全忘记将name值添加到选择内容和$post

在元数据框渲染中：

<select name="ratings">

在save_posts()函数

中

$ms_field_select = $_POST['ratings'];

Meta box下拉菜单不保存在我的自定义帖子类型中
