当我从下拉列表中选择类别时，一切都正常。但在后端，它只选中了子项，而不是父项

这里是我的代码

<?php if(isset($_POST[\'new_post\']) == \'1\') {
    $post_title = $_POST[\'post_title\'];
    $post_category = $_POST[\'cat\'];
    $post_content = $_POST[\'post_content\'];
    $parent = get_the_tags($post_category);;




    $new_post = array(
          \'ID\' => \'\',
          \'post_author\' => $user->ID, 
          \'post_category\' => array($parent,$post_category),
          \'post_type\' => \'currencies\',
          \'post_content\' => $post_content, 
          \'post_title\' => $post_title,
          \'post_status\' => \'publish\'
        );

    $post_id = wp_insert_post($new_post); print_r($post_id);
    // This will redirect you to the newly created post
    $post = get_post($post_id);    echo "Done";
    }       ?>   

<h1fhsdfh</h1> <form method="post" action=""> 
    <label>Post-Title:-</label><br><label><input type="text"  class="form-control"  name="post_title" size="45"
id="input-title"/></label><br>   
<label>Catogries:-</label><br><label > <?php
wp_dropdown_categories(\'orderby=name&hide_empty=0&exclude=1&hierarchical=1\');
?> </label><br>

    <label>Content:-</label><br><label><textarea  class="form-control"  rows="5" name="post_content" cols="66"
id="text-desc"></textarea> 
    <input type="hidden" name="new_post" value="1"/> </label>
    <input class="subput round form-control"   type="submit" name="submit" value="Post"/> </form> <?php get_footer(); ?>

请查看此图像http://prntscr.com/j9toiz

// Add the custom columns to the post post type: add_filter( \'manage_post_posts_columns\', \'set_custom_edit_post_columns\' ); function set_custom_edit_post_columns($columns) { $columns[\'parent_cat\'] = __( \'Parent Category\', \'storefront\' ); return $columns; } // Add the data to the custom columns for the post post type: add_action( \'manage_post_posts_custom_column\' , \'custom_post_column\', 10, 2 ); function custom_post_column( $column, $post_id ) { if($column == \'parent_cat\'){ $terms = get_terms(\'category\'); foreach ($terms as $term) { if($term->parent == 0){ echo $term->name; } } } }
