I want to get return value of a function and display it to a specific id.
In my Class.php I have a function named login that validates if the password is correct/incorrect
<?php
class Class
{
public function login()
{
if($_POST['password'] == Match) {
return 'Correct Password!';
} else {
return 'Incorrect password!';
}
}
}
and in my my index.php I have this html. now how can I get the return value of my login function in my html tag with an ID of check
<?php
require_once 'Class.php';
$class = new Class();
$class->login();
?>
<!DOCTYPE html>
<html>
<head>
<title>SOMETHING</title>
</head>
<body>
<form action="" method="POST">
<input type="text" name="username">
<input type="password" name="password">
<span id="check"></span> <!-- I want to put the returned value here -->
<input type="submit" value="Login">
</form>
</body>
</html>
解决方案
<?php
require_once 'Class.php';
$class = new Class();
$returnedValue = $class->login();
?>
<!DOCTYPE html>
<html>
<head>
<title>SOMETHING</title>
</head>
<body>
<form action="" method="POST">
<input type="text" name="username">
<input type="password" name="password">
