I have the following form on "test.php".
<?php
session_start();
if(isset($_POST['ph']))
if(isset($_POST['submit']))
$_SESSION['ph'] = $_POST['ph'];
?>
<!doctype html>
<html lang="en">
<body>
<form method="POST" action="order.php" id="custphoneform">
<label for="PhoneNumber">Enter Phone Number:</label>
<input type="number" name="ph" required>
<input type="submit" value="Submit" name="submit">
</form>
</body>
</html>
The "order.php" looks like this:
<?php
require 'connection.php';
session_start();
if(isset($_SESSION['ph']))
echo ($_SESSION['ph']);
?>
The first time I load the "test.php" and input the phone number it works perfectly and gives me the correct output on "order.php", but the second time onward, "order.php" gives me the same value which I had entered the first time even though I input a different value. I refreshed the page, same result.
I closed the file and reloaded it, still same value. Why is it behaving that way and how do I correct it? I want session to change value whenever a new number is entered which is not happening.
Change the new value to SESSION ON your order.php page like below:-
<?php
require 'connection.php';
session_start();
if(!empty($_POST['ph'])){
$_SESSION['ph'] = $_POST['ph']; //change value of phonenumber inside SESSION
}
if(!empty($_SESSION['ph'])){
echo ($_SESSION['ph']);
}
?>
Also change test.php code like this:-
<?php
session_start(); // no need to do other stuff
?>
<!doctype html>
<html lang="en">
<body>
<form method="POST" action="order.php" id="custphoneform">
<label for="PhoneNumber">Enter Phone Number:</label>
<input type="number" name="ph" required>
<input type="submit" value="Submit" name="submit">
</form>
</body>
</html>
