Redirecting a User to Another Page After PHP Form Submission

Challenge

Many users have encountered difficulties redirecting users to another page after submitting a form in PHP. This issue arises when developers attempt to replace the current page's content with custom "success" HTML without considering the proper timing.

The Solution

To resolve the issue, the redirect header should be added immediately after the @mail($email_to, $email_subject, $email_message, $headers); line.

<code class="php"><?php
    // ...
    @mail($email_to, $email_subject, $email_message, $headers);
    // Redirect to another PHP page
    header('Location: nextpage.php');
    // ...
?></code>

Explanation

1. The @mail function sends the email.
2. The header function sets the HTTP response header, which instructs the browser to redirect to a new URL.
3. It's crucial to avoid output after setting the header. Any subsequent output (including a blank space or line break) will cause errors and prevent redirection.

Note

This method of redirection will prevent the "Thanks for subscribing to our mailing list" message from displaying on the current page. Instead, this message should be displayed on the redirected page.
