我使用以下源代码添加了一个额外的city
我的WordPress评论表单的字段:
<?php
/*
Plugin Name: Comment meta data test
Version: 1.0
Plugin URI: http://wpengineer.com
Description: Comment meta data test
Author: Latz
Author URI: http://wpengineer.com
*/
add_filter( \'comment_form_defaults\', \'change_comment_form_defaults\');
function change_comment_form_defaults($default) {
$commenter = wp_get_current_commenter();
$default[\'fields\'][\'email\'] .= \'<p class="comment-form-author">\' .
\'<label for="city">\'. __(\'CITY\') . \'</label>
<input id="city" name="city" size="30" type="text" /></p>\';
return $default;
}
add_filter( \'preprocess_comment\', \'verify_comment_meta_data\' );
function verify_comment_meta_data($commentdata) {
if ( ! isset( $_POST[\'city\'] ) )
wp_die( __(\'Error: please fill the required field (city).\') );
return $commentdata;
}
add_action( \'comment_post\', \'save_comment_meta_data\' );
function save_comment_meta_data( $comment_id ) {
add_comment_meta( $comment_id, \'city\', $_POST[\'city\'] );
}
add_filter( \'get_comment_author_link\', \'attach_city_to_author\' );
function attach_city_to_author( $author ) {
$city = get_comment_meta( get_comment_ID(), \'city\', true );
if ( $city )
$author .= " $city ";
return $author;
}
?>
这将显示额外字段和注释表单,其输出将与注释作者姓名一起显示。
但是,我只想显示城市名称,不想显示作者名称。我该怎么做?
