Disable Back Functionality In Php Using Javascript
There is a smart
technique to disable the back functionality in any webpage. We can disable the
back navigation by adding following bit of code in the webpage. Now the problem here is that you have to add this code in all
the pages where you want to avoid user to get back from previous page. For
example a user makes the navigation from
page1 to page2. And we want to stop user
from page2 to go back to page1. In this case add following code will be added in php page1.
|
<HEAD>
<SCRIPT type="text/javascript">
window.history.forward();
function noBack() {
window.history.forward(); }
</SCRIPT>
</HEAD>
<BODY onload="noBack();"
onpageshow="if
(event.persisted) noBack();"
onunload="">
|
The above code will
trigger history.forward event for page1. That is if user presses Back button on page2, he will
be sent to page1. But the history.forward code on page1 makes the user back to
page2. Thus user will not be able to go back from page2 to page1.
