Question

我陷入了为wordpress类别创建选择自定义字段并在管理表中显示所选元数据的问题。

我有一个代码可以创建类别中的自定义字段，并将其保存在数据库中。它还在管理表中创建列。我的问题是，它始终显示第一个值，而不显示所选的值。我做了一个if语句，但是没有用。你能告诉我我哪里做错了吗？

代码：

<?php 
    function add_extra_fields_to_category($taxonomy_name){
   ?>
   <div class="form-field">
     <label for="category-realized">Was the project finished?</label>
     <select name="category-realized" id="category-realized">
        <option value="2"> No </option>
        <option value="1"> Yes </option>
     </select>
  </div>
 <?php
 }

 add_action('category_add_form_fields','add_extra_fields_to_category');

function save_extra_taxonomy_fields($term_id){
//collect all term related data for this new taxonomy
$term_item = get_term($term_id);

    //collect our custom fields
    $term_category_select = sanitize_text_field($_POST['category-realized']);

    //save our custom fields as wp-options
    update_term_meta($term_id, 'term_category_realized', $term_category_select);
     }

    add_action('create_category','save_extra_taxonomy_fields');

   function edit_extra_fields_for_category($term){

    //collect our saved term field information
    $term_category_select = get_term_meta('term_category_realized');

    //output our additional fields?>
    <tr class="form-field">
     <th valign="top" scope="row">
        <label for="category-realized">Was the project finished?</label>

    </th>
    <td>
        <select name="category-realized" id="category-realized" value="<?php echo $term_category_select; ?>">
            <option value="2" <?php if($term_category_select === '2'){ echo 'selected';}?>> No </option>
            <option value="1" <?php if($term_category_select === '1'){ echo 'selected';}?>> Yes </option>
        </select>
    </td>
</tr>

<?php
}

add_action('category_edit_form_fields','edit_extra_fields_for_category');

add_action('edit_category','save_extra_taxonomy_fields');

 // Add column to Category list

 function category_realized_columns($columns)
  {
    return array_merge($columns, array('term_category_realized' =>  __('Was the project finished?')));
}

add_filter('manage_edit-category_columns' , 'category_realized_columns');

// Add the value to the column

function category_realized_columns_values( $deprecated, $column_name, $term_id) {

if($column_name === 'term_category_realized'){

    $meta = get_term_meta($term_id);

    echo '<pre>'; var_export($meta['term_category_realized']); echo '</pre>';

    if ($meta['term_category_realized'] === '1') {
        echo _e('Yes');
    } else {
        echo _e('No');
    }
  }
 }

 add_action( 'manage_category_custom_column' , 'category_realized_columns_values', 10, 3 );
 ?>

在Wordpress管理表中Dipslay选定的值
