Question

为此，我将自定义字段添加到类别：

add_action ( 'edit_category_form_fields', function( $tag ){
    $cat_title = get_term_meta( $tag->term_id, '_pagetitle', true ); ?>
    <tr class='form-field'>
        <th scope='row'><label for='cat_page_title'><?php _e('Category Page Title'); ?></label></th>
        <td>
            <input type='text' name='cat_title' id='cat_title' value='<?php echo $cat_title ?>'>
            <p class='description'><?php _e('Title for the Category '); ?></p>
        </td>
    </tr> <?php
});

add_action ( 'edited_category', function() {
    if ( isset( $_POST['cat_title'] ) )
        update_term_meta( $_POST['tag_ID'], '_pagetitle', $_POST['cat_title'] );
});

然后我尝试使用ajax添加我自己的文本：

  function data_person(){
    $catname = $_POST['catName'];
    $surnameCat = $_POST["surnameCat"];
    $cityCat = $_POST["cityCat"];
    $catDob = $_POST["dobCat"];
    $catBio = $_POST["catBio"];
    $cat_ID = get_cat_ID( sanitize_title_for_query($catname) );  
    // Check if category exists
    if($cat_ID == 0) {
        $cat_name = $catname;  
        $cat_sur = $surnameCat;
        $cat_city = $cityCat;  
        $cat_dob = $catDob;
        $cat_bio = $catBio;
        $cat_slug = sanitize_title_with_dashes($cat_name);
        $my_cat = array(
          'cat_name' => $cat_name, 
          'category_description' => $cat_bio, 
          'cat_title' => $cat_sur, 
          'category_nicename' => $cat_slug, 
          'category_parent' => 0
        );
        if( wp_insert_category( $my_cat ) ) {
          echo json_encode("Category added successfully");
        } else {
          echo json_encode("That category already exists");
        }
    } else {
      echo json_encode("That category already exists");
    }
    exit;
  }

但是我不确定如何将文本添加到新创建的自定义字段中，这不起作用：'cat_title' => $cat_sur,，因为它没有保存单击后从输入字段发送的值。基本上应该代替'cat_title' =>放什么？

更新

这是完整的代码，因此在function.php中，我们有：

add_action ( 'edit_category_form_fields', function( $tag ){
    $cat_title = get_term_meta( $tag->term_id, '_pagetitle', true ); ?>
    <tr class='form-field'>
        <th scope='row'><label for='cat_page_title'><?php _e('Category Page Title'); ?></label></th>
        <td>
            <input type='text' name='cat_title' id='cat_title' value='<?php echo $cat_title ?>'>
            <p class='description'><?php _e('Title for the Category '); ?></p>
        </td>
    </tr> <?php
});

add_action ( 'edited_category', function() {
    if ( isset( $_POST['cat_title'] ) )
        update_term_meta( $_POST['tag_ID'], '_pagetitle', $_POST['cat_title'] );
});

  add_action( 'wp_footer', 'ajax_Person' );

  function ajax_Person() { ?>
    <script type="text/javascript">
    jQuery("#saveperson").on("click", function(e){
      e.preventDefault();
      person();
    });
    function person(){
      jQuery.ajax({
        url: '<?php echo admin_url('admin-ajax.php'); ?>',
        type: 'post',
        data: { action: 'data_person', catName: jQuery('#nameCat').val(), catSurnam: jQuery('#surnameCat').val(), catCity: jQuery('#cityCat').val(), catDob: jQuery('#dobCat').val(), catBio: jQuery('#bioCat').val()  },
        success: function(data) {
          jQuery(".modal-body .help-text").html(data);
        }
      });
    }
    </script>
  <?php }

  add_action('wp_ajax_data_person' , 'data_person');
  add_action('wp_ajax_nopriv_data_person','data_person');

  function data_person(){
    $catname = $_POST['catName'];
    $surnameCat = $_POST["surnameCat"];
    $cityCat = $_POST["cityCat"];
    $catDob = $_POST["dobCat"];
    $catBio = $_POST["catBio"];
    $cat_ID = get_cat_ID( sanitize_title_for_query($catname) );  
    // Check if category exists
    if($cat_ID == 0) {
      $my_cat = array(
        'cat_name' => $cat_name, 
        'category_description' => $cat_bio, 
        'category_nicename' => $cat_slug, 
        'category_parent' => 0
      );
      $cat_id = wp_insert_category( $my_cat );
      if( ! is_wp_error( $cat_id ) && (int)$cat_id ) {
        // NOW, add the metadata...
        add_term_meta( $cat_id, '_pagetitle', $surnameCat );
        echo json_encode("Category added successfully");
      } else {
        echo json_encode("That category already exists");
      }
    }
    exit;
  }

还有html：

<div class="col-xs-12">
    <div class="add-pearson-form memory-form">
        <div class="m-form-wrap">
            <a href="javascript:;" class="frm_close"><i class="fa fa-times-circle"></i></a>
            <div class="team_person">
                <div class="form-group">
                    <div class="col-xs-12 col-sm-8 col-sm-offset-2">
                        <h4 class="text-center text-uppercase">aggiungi una persona</h4>
                        <input type="text" class="form-control" placeholder="NOME">
                        <input type="text" class="form-control" placeholder="COGNOME">

                        <div class="text-center">

                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

Answer 1

您的问题的答案是使用add_term_meta函数。

请勿将a=2; n=5; /* to generate numbers up to 27 */ for (i=3;i<n+3;i++) { a+=i; printf("%d",a); }插入类别-wp_insert_category函数不接受/使用该参数。

相反，要从 cat_title返回类别ID，然后使用该ID添加元值。

请参阅下面的修改/简化代码，并附上说明更改的注释：

wp_insert_category

如何将自定义字段添加到类别并进行查询？
