我是Wordpress的新手，我有一个函数可以将我插件的表放到DB上。

<?php

if (! defined(\'WP_UNINSTALL_PLUGIN\')) {
exit;
}

// Uninstallation actions here

global $wpdb;

$table_names = [
    $wpdb->prefix . "questions",
    $wpdb->prefix . "difficulties",
    $wpdb->prefix . "modalities",
    $wpdb->prefix . "fields",
    $wpdb->prefix . "themes",
    $wpdb->prefix . "subjects",
    $wpdb->prefix . "disciplines",
    $wpdb->prefix . "training_areas",
    $wpdb->prefix . "levels",
    $wpdb->prefix . "roles",
    $wpdb->prefix . "banks",
];

foreach ($table_names as $table_name) {
    $wpdb->query("DROP TABLE IF EXISTS $table_name");
}

它确实删除了所有的表，但是我如何阻止这个错误呢？
