I'm very new to PHP, and I can't solve an issue even I read a lot of tutorials and SO posts. I've a custom class (user), and I'd like to instantiate it in php code, but even I include it, I get this error.
Fatal error: Class 'User' not found in D:\wamp64\www\MyFirstPhp\formPhp.php on line 17
Please help me find out what I do wrong.
Here is my user class:
<?php
/**
* Created by IntelliJ IDEA.
* User: molnard
* Date: 2017. 06. 06.
* Time: 15:36
*/
namespace infopro;
class User
{
private $username;
private $userage;
private $sex;
public function __construct($username, $userage, $sex)
{
if (!is_null($username)) $this->username = $username;
if (!is_null($userage)) $this->userage = $this->userage;
if (!is_null($sex)) $this->sex = $sex;
}
/**
* @return mixed
*/
public function getUsername()
{
return $this->username;
}
/**
* @param mixed $username
*/
public function setUsername($username)
{
$this->username = $username;
}
/**
* @return mixed
*/
public function getUserage()
{
return $this->userage;
}
/**
* @param mixed $userage
*/
public function setUserage($userage)
{
$this->userage = $userage;
}
/**
* @return mixed
*/
public function getSex()
{
return $this->sex;
}
/**
* @param mixed $sex
*/
public function setSex($sex)
{
$this->sex = $sex;
}
}
?>
And here is my form.php class where I'd like to instantiate user class.
<!Doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Form php</title>
</head>
<body>
<?php
include("User.php");
$name = $_POST["name"];
$age = $_POST["age"];
$sex = $_POST["sex"];
echo "New user<br>name: " . $name . "<br>" .
"age: " . $age . "<br>" . "sex: " . $sex."<br>";
$newuser = new User($name, $age, $sex);
$newAge = $newuser->getAge();
echo $newAge;
?>
</body>
</html>
The exception already told you, whats wrong with your code. There's no such User class. If you use namespaces, and your currently in another namespace (or no namespace), you have to use fully qualified names. Means: namespace + classname.
In your case, you have to prefix your class name with the namespace infopro, which leads to \infopro\User
$user = new \infopro\User(...);
If you don't want to use always the fqn and you are in a diffrent namespace, you could also import the classname into the local scope of the file with use.
use \infopro\User;
// somewhere later ...
$user = new User(...);
Try
$newuser = new \infopro\User($name, $age, $sex);
Or
<?php
use \infopro\User;
?>
<!Doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Form php</title>
</head>
<body>
<?php
include("User.php");
$name = $_POST["name"];
$age = $_POST["age"];
$sex = $_POST["sex"];
echo "New user<br>name: " . $name . "<br>" .
"age: " . $age . "<br>" . "sex: " . $sex."<br>";
$newuser = new User($name, $age, $sex);
$newAge = $newuser->getAge();
echo $newAge;
?>
</body>
</html>
Since you are using namespace in your class you'll have to use that namespace to properly include User class.
try adding use \infopro\User;: `
<?php
include "User.php";
use \infopro\User;
$name = 'talib';
$age = '29';
$sex = 'male';
echo "New user<br>name: " . $name . "<br>" .
"age: " . $age . "<br>" . "sex: " . $sex."<br>";
$newuser = new User($name, $age, $sex);
$newAge = $newuser->getUserage();
echo $newAge;
?>
Thanks, all answer was good. I use intelij, and I've just realised namespace just optional, I can use global namespace if I leave it blank.
