Question

当我尝试激活自定义插件时，收到以下错误：

WordPress数据库错误为查询定义的多个主键ALTER TABLE temp CHANGE COLUMN id id int（11）UNSIGNED AUTO_INCREMENT PRIMARY

private function runDbMigration_20() {
    $sql = "CREATE TABLE " . PREFIX . "subscribers (
    id int(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,     
    name tinytext NOT NULL,
    email text NOT NULL,
            secretkey text NOT NULL,
            random_key text NOT NULL,
            onehourmailsent int(1) NOT NULL DEFAULT 0,
            onedaymailsent int(1) NOT NULL DEFAULT 0,
            wbstartingmailsent int(1) NOT NULL DEFAULT 0,
            replaymailsent int(1) NOT NULL DEFAULT 0,
            temp_id int(11) NOT NULL,
            exact_time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            watch_day varchar(3),
            watch_time time,
            time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            last_seen datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            active int(1) UNSIGNED NOT NULL DEFAULT 1,
            high_five int(1) UNSIGNED NOT NULL DEFAULT 0,
            attended int(1) UNSIGNED NOT NULL DEFAULT 0
)" . $this->CHARSET_COLLATE . ";";
    return $this->calldbDelta($sql);
}

请问，有人可以帮我解决这个错误吗？

最后添加 PRIMARY KEY（id）解决了错误

private function runDbMigration_20() {
    $sql = "CREATE TABLE " . WSWEB_DB_TABLE_PREFIX . "subscribers (
    id int(11) UNSIGNED AUTO_INCREMENT,     
    name tinytext NOT NULL,
    email text NOT NULL,
            secretkey text NOT NULL,
            random_key text NOT NULL,
            onehourmailsent int(1) NOT NULL DEFAULT 0,
            onedaymailsent int(1) NOT NULL DEFAULT 0,
            wbstartingmailsent int(1) NOT NULL DEFAULT 0,
            replaymailsent int(1) NOT NULL DEFAULT 0,
    temp_id int(11) NOT NULL,
            exact_time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            watch_day varchar(3),
            watch_time time,
            time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            last_seen datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
            active int(1) UNSIGNED NOT NULL DEFAULT 1,
            high_five int(1) UNSIGNED NOT NULL DEFAULT 0,
            attended int(1) UNSIGNED NOT NULL DEFAULT 0,
            PRIMARY KEY  (id)
)" . $this->CHARSET_COLLATE . ";";
    return $this->calldbDelta($sql);
}
