Question

它不会更新它一直给我错误的数据。如果电子邮件已经存在，它应该告诉我电子邮件存在，但它无法更新用户数据。

它给了我这个错误：

警告：PDOStatement :: execute（）：SQLSTATE [HY093]：参数号无效：第37行的C：\ xampp \ htdocs \ php.dev \ classes \ Model.php中没有绑定任何参数

Answer 1

您的类函数execute（）需要接受sql字符串中绑定参数的数组值。

在分类/ Model.php中更改：

rootTreeNode = new tree{DataToInsert, nullptr, nullptr};

要

public function execute() { $this->stmt->execute(); }

您没有将变量绑定到sql字符串中的指定变量名。

models / user.php - 替换：

public function execute($params=NULL) { $this->stmt->execute($params); }

使用：

$this->execute();

更新用户数据会导致PDO异常
