Retrieve Data from POST Method and Display in HTML H1 Tag

Greetings,

I am developing a website using WordPress and elementor. I have a form with the POST method on page1 which is redirecting the user to page2. How do I receive that data on page2 and display it in the H1 tag on the same page?

Answer

Data submitted from a form with the method='post' attribute can be accessed using the $_POST superglobal. For example:

// page1.php
<form action='/page2.php' method='post'>
    <input type='text' name='name' placeholder='Enter your name' />
    <input type='submit' value='Send' />
</form>

// page2.php
<?php

$name = $_POST['name'] ?? 'World';

?>

<h1>
    Hello, <?php echo $name; ?>
</h1>
