此查询有效：

$player_id = $_POST['player_id'];//array

$ids = explode(',',$player_id);
$in = implode(',', array_fill(0, count($ids), '%d'));

$wpdb->query($wpdb->prepare("DELETE FROM {$player_table} WHERE id IN ($in)", $ids));

这不会：

$disabled = $_POST['disabled'];
$media_id = $_POST['media_id'];//array

$ids = explode(',',$media_id);
$in = implode(',', array_fill(0, count($ids), '%d'));

$wpdb->query($wpdb->prepare("UPDATE {$media_table} SET disabled = %s WHERE id IN ($in)", $disabled, $ids));

我不明白为什么。
