BackButton Functionality

Hi all

How can i implement the browser\'s back button functionality to \"html button\" using php.

Please help me.

The best you can do is use javascript (which doesn't work in all browsers).

<INPUT TYPE='button' onClick='Javascript:history.back()' VALUE='Cancel'>

Good question. How you achieve that with php depends on your script. For instance, you could use query strings. Javascript is what I've used in the past. If you're interested, here it is:

&lt;form>
&lt;input type="button" OnClick="history.back()"; value="Back">
&lt;input type="button" OnClick="history.forward()"; value="Forward">
&lt;/form>

$HTTP_REFERER will work for Back.

if(!empty($HTTP_REFERER)) {
echo '<A href="'.$HTTP_REFERER.'Back</a>';
}
