How to Enable Back Button Functionality for .htaccess Routing in PHP?

Refresh Page on Back Button Click

In .htaccess file routing, users often encounter issues when using the back button to navigate within a single index.php file. This article delves into a solution to resolve this back button functionality problem.

A typical code snippet for .htaccess-based routing is provided below, directing traffic to various HTML pages based on URL parameters:

<code class="php">if(isset($_GET['parameters'])) {
   if($_GET['parameters'] == "repair")
      include 'repair.html';
      ...
} else
      include 'home.html';
?></code>

However, this setup may hinder the back button's functionality. To address this, two alternate approaches are presented:

Method 1: Dynamic timestamp injection

Create a new PHP file to insert a timestamp into the page. This timestamp will update dynamically as you navigate using the back and forward buttons.

<code class="php">header("Cache-Control: no-store, must-revalidate, max-age=0");
header("Pragma: no-cache");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
echo time();</code>

Method 2: Leverage onload event

Utilize the onload event to check if the user has visited the page before. If not, mark the visit as true; otherwise, reload the page.

<code class="html"><input type="hidden" id="refreshed" value="no"></code>
<code class="javascript">onload=function(){
var e=document.getElementById("refreshed");
if(e.value=="no")e.value="yes";
else{e.value="no";location.reload();}
}</code>

By implementing either of these solutions, you can overcome the limited back button functionality often associated with .htaccess file routing.
