What could be causing a form to redirect to the index page instead of the intended page in PHP?

The issue could be caused by incorrect form action or redirection code in the PHP script. To solve this issue, ensure that the form action points to the correct PHP script and that the redirection code is correctly implemented with the header() function in PHP. 

// Ensure that the form action points to the correct PHP script
<form action="process_form.php" method="post">
    // Form inputs
</form>

// In process_form.php, after processing the form data:
header("Location: intended_page.php");
exit();
