我为CRUD数据库wordpress制作插件，但是当我点击提交link_id时总是返回0
错误信息
string(992) "UPDATE `wp_search` SET `id` = '1',
`name` = 'Ini Vie',
`location` = 'Seminyak',
`price` = '160',

`des_en` = 'Ini Vie Villa is a stylish lifestyle boutique romantic villa which located in Legian, offers One Bedroom and Two Bedrooms Villa with private pool & Jacuzzi with perfection traditional personalize Balinese hospitality service, a quiet yet stylish area, a more sophisticated atmosphere than the hustle and bustle of nearby Kuta.',
`link_id` = 0,

正如您所见link_id总是0，但实际上它不是0

谢谢
答案 0 :(得分：0)
我找到了解决方案，我更改了此代码
$result = $wpdb->update($table_name, $item, array('id' => $item['id']));
到
$sql ="UPDATE $table_name
SET `name`= '".$item['name']."',
`location` = '".$item['location']."',
`price` = '".$item['price']."',
`room` = '".$item['room']."',
`des_id` = '".$item['des_id']."' ,
`des_en` = '".$item['des_en']."',
`link_id` = '".$item['link_id']."',
`link_en` = '".$item['link_en']."',
`link_img` = '".$item['link_img']."',
`type` = '".$item['type']."'
WHERE `id` = '".$item['id']."'";
$result = $wpdb->query($sql);
我的问题已经完成。
