Question

我试过了：

$cid = mysql_insert_id($this->result);
$this->result = "<div class='alert alert-success'>" . sprintf(_('Successfully added user id <b>%s</b> to the database.'), $cid) . "</div>";

但我只收到此错误：

警告：mysql_insert_id（）：提供的参数不是

中有效的MySQL-Link资源

这是整个函数（我添加了 $ cid = mysql_insert_id（$ this-＆gt; result）; 希望检索插入数据的id）：

private function adduser() {

    if (!empty($this->error)) return false;

    $params = array(
        ':user_level' => parent::getOption('default-level'),
        ':name'       => $this->name,
        ':email'      => $this->email,
        ':username'   => $this->username,
        ':password'   => parent::hashPassword($this->password)
    );

    parent::query("INSERT INTO `login_users` (`user_level`, `name`, `email`, `username`, `password`)
                    VALUES (:user_level, :name, :email, :username, :password);", $params);

    $shortcodes = array(
        'site_address'  =>  SITE_PATH,
        'full_name'     =>  $this->name,
        'username'      =>  $this->username,
        'email'         =>  $this->email,
        'password'      =>  $this->password
    );

    $subj = parent::getOption('email-add-user-subj');
    $msg = parent::getOption('email-add-user-msg');

    if(!parent::sendEmail($this->email, $subj, $msg, $shortcodes))
        $this->error = _('ERROR. Mail not sent');
    $cid = mysql_insert_id($this->result);
    $this->result = "<div class='alert alert-success'>" . sprintf(_('Successfully added user <b>%s</b> to the database. Credentials sent to user.'), $cid) . "</div>";

}

这是与数据库的连接：

<?php
$host = "xxx"; 
$dbName = "xxx"; 
$dbUser = "xxx"; 
$dbPass = "xxx"; 
?>

Answer 1

mysql_insert_id()将资源链接（即数据库句柄）作为参数而不是查询结果。 $this->result包含哪些内容？

Answer 2

检查Manual

mysql_insert_id的参数是Link_Identifier。但我猜你是在传递结果。尝试

$cid = mysql_insert_id();

或$ this-＆gt;结果必须是mysql_connect（）返回的连接标识符。

Answer 3

您已使用PDO，请切换到：

$cid = self::$dbh->lastInsertId(); // PDO for mysql_insert_id

无法让mysql_insert_id（）工作
