创建一个.php 在WordPress目录的根目录中创建文件并写入：

<?php
require( \'wp-load.php\' );

$urunler = array(
    \'order\'          => \'ASC\',
    \'post_type\'      => \'urun\',
    \'post_status\'    => null,
    \'numberposts\'    => -1,
);

$tumurunler = get_posts($urunler);
if ($tumurunler) {
  foreach ($tumurunler as $urun) {
    $urun->post_name = \'\';
    wp_update_post( $urun );   // Update the post into the database
  }
}

所以这段代码会加载post_type==\'urun\' 并设置$urun->post_name 字段为空（此字段定义后permalink段塞），然后在调用时WordPress会自动为您填充一个值wp_update_post(). 如果你想改变post_type\' 到\'post\' 或post_type\' 到\'page\' 只需更改此行：

\'post_type\'      => \'urun\',
