pocobueno1388 Posted October 25, 2007 Share Posted October 25, 2007 How to you use "backspace" to link back to your previous page? Your going to have to explain more, and maybe give us some code to look at.

unidox Posted October 25, 2007 Share Posted October 25, 2007 Use $_SERVER['PHP_SELF'] It goes to the previous viewed page.

pocobueno1388 Posted October 25, 2007 Share Posted October 25, 2007 Use $_SERVER['PHP_SELF'] It goes to the previous viewed page. No, thats wrong. $_SERVER['HTTP_REFERER'] will give you the last page.

pocobueno1388 Posted October 25, 2007 Share Posted October 25, 2007 If you want to link to the previous page, do this <?php echo "<a href='{$_SERVER['HTTP_REFERER']}'>Previous Page</a>"; ?> Link to comment https://forums.phpfreaks.com/topic/74675-solved-using-bakspace-cannot-link-back-to-previous-page/#findComment-377516 Share on other sites More sharing options...

pocobueno1388 Posted October 25, 2007 Share Posted October 25, 2007 They could, if there browser supports that. I'm not sure if there are any that don't. For a good web page, I would put a back button if it's necessary.

PHP_PhREEEk Posted October 25, 2007 Share Posted October 25, 2007 The backspace is a browser function. PHP cannot map keyboard functions on the client side. If your website is coming up expired when going back, then a POST or GET must have been used to get to that page to begin with. You should get additional error text that says click ok to resend data or similar. There is no workaround other than a hard 'Previous' link. Lastly, a META tag may be causing the page to expire, so check that they are all correct.

darkfreaks Posted October 25, 2007 Share Posted October 25, 2007 you can use javascript to form a previous link as well <a href="#" onClick="history.go(-1)">Previous</a> Link to comment https://forums.phpfreaks.com/topic/74675-solved-using-bakspace-cannot-link-back-to-previous-page/#findComment-377539 Share on other sites More sharing options...
