嗨,我正在尝试读取我的对象 person 的实例,使用表单获取其个人详细信息,然后将其放入数据库中。我想我的代码设置了这个人,并连接到数据库好,我只是在处理表单信息并将其读入数据库时无法正确处理。任何帮助将不胜感激!
我的表格
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
</head>
<body>
<form action="process.php" method="post">
First Name: <input type="text" name="firstName" />
Last Name: <input type="text" name="lastName" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>
我尝试处理它的地方
<?php
$i = 0;
$firstName = 'firstName';
$lastName = 'lastName';
$age = 'age';
$person = new person ($i,$firstName, $lastName, $age);
$PersonDAO = new PersonDAO();
$dao->insert($person);
?>
我的道
类 PersonDAO 扩展 Person{ protected $link;
public function __construct() {
$host = "localhost";
$database = "test";
$username = "root";
$password = "";
$dsn = "mysql:host=$host;dbname=$database";
$this->link = new PDO($dsn, $username, $password);
$this->link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
public function __destruct() {
$this->link = null;
}
public function insert($person){
if (!isset($person) && $person != null){
throw new Exception("Person Required");
}
$sql = "INSERT INTO person(firstName, lastName, age)"
. "VALUES (:firstName, :lastName, :age)";
$params = array(
'firstName' => $person->getFirstName(),
'lastName' => $person->getLastName(),
'age' => $person->getAge(),
);
$stmt = $this->link->prepare($sql);
$status = $this->execute($params);
if ($status != true){
$errorInfo = $stmt->errorInfo();
throw new Exception("Could Not Add Person: " . $errorInfo[2]);
}
$id = $this->link->lastInsertId('person');
$person->setId($id);
}
} ?>
我的表单很好,但是当我单击提交时,它显示“致命错误:在第 6 行的 /Applications/XAMPP/xamppfiles/htdocs/personProj/process.php 中找不到类 'person'”
有任何想法吗?谢谢
