我正在尝试使用php oop显示我的数据库中的所有用户。我真的不知道如何包含user.php的成connectionFile.php或一些可能work.my代码:user.php的:显示数据库中的所有用户php oop
public class User{
protected $firstname;
protected $lastname;
protected $email;
protected $password;
protected $age;
protected $role;
protected $file;
protected $db;
public function __construct($DB_con){
$this->db = $DB_con;
}
public function __construct($firstname, $lastname, $email){
$this->firstname = $firstname;
$this->lastname = $lastname;
$this->email = $email;
}
public function getFirstname(){
return $this->firstname;
}
public function getLastname(){
return $this->lastname;
}
public function getEmail(){
return $this->email;
}
public function setFirstname($firstname){
$this->firstname = $firstname;
}
public function setLastname($lastname){
$this->lastname = $lastname;
}
public function setEmail($email){
$this->email = $email;
}
public function getAllUsers(){
try{
$stmt = $this->db->prepare("select * from user");
$stmt->execute();
return $stmt;
}catch(PDOException $e){
echo $e->getMessage();
}
}
}
我connectionFile.php:
require_once ("user.php");
// session_start();
$servername = "localhost";
$username = "root";
$password = "root";
$database = "first_project";
try {
$conn = new PDO("mysql:host=$servername;dbname=first_project", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// echo "Connected successfully";
}
catch(PDOException $e){
echo "Connection failed: " . $e->getMessage();
}
和我displayResult.php(我也有形式的页面HTML):
<?php
require_once("connectionFile.php");
//include_once 'user.php';
if(isset($_POST['button'])){
//$user = new User();
echo "skksksks";
}
else{
echo "v";
}
?>
的按钮工作,我想在按钮后调用从用户类功能getAllusers但我真的不知道该怎么因为每一次我尝试将该文件包含在任何地方,以使我找不到页面。
你已经包括connectionFile user.php的文件。 PHP。您不需要将其包含在displayResult.php中 –
