Reset Back button

[LLX]

i'm trying to find a way to reset the back button so when incrementing through my forms the users can't acidently go back to a previous page

You cannot clear the existing history but you can make sure a newly
selected page replaces the previous one preventing building up a
history. You do so by calling
location.replace('newPage.htm');
instead of assigning
location.href = 'newPage.htm';
The location.replace('url') call will replace the current page in the
history list with the new page thus preventing backing to the current
page.
You might also use that in a link with
<A HREF="javascript:location.replace('newPage.htm');">link</A>

The back button cannot be disabled besides using the above technique
for preventing backing or besides opening a new window without
toolbar/menubar.

thanks, wanted to prevent users for doble processing a registration form, i dont even use pos to set varibles i use post for error checking then use session and redirect to move to the second form.

so if imy php is set up like this

<img src="spacer.gif" width=1 height=1 onLoad="javascript: location.href=\''.$SSL.$MainDir.$RegPage.'?LAID=1&AID=2&CCID='.$_GET['CCID'].'&SETID='.$_GET['SETID'].'&SelectID='.$_GET['SelectID'].'\'">

i shoud change it to what to it redirects and replaces?

You could also disable the submit button once it's been clicked.

and that will redirect as well as replace?

[rlemon]

that will replace the current page with the page specified in the browser window as well as history.

so to answer your question, yes.

i tried it but it didnt do anything, as popos to the redirect thati normal get the page just sits there

echo '<img src="spacer.gif" width=1 height=1 onLoad="javascript: location.replace=\''.$SSL.$MainDir.$StudentPage.'?LAID=1&AID=50&CCID='.$_GET['CCID'].'\'">';

heres a snip of the relevent code when its not 'replace'

if (trim($_GET['CCID']) == '' AND trim($_POST['CCID']) != ''){
$_GET['CCID'] = $_POST['CCID'];
Echo 'If you are not redirected in a moment click <a href="'.$SSL.$MainDir.$StudentPage.'?LAID=1&AID=50&CCID='.$_GET['CCID'].'">here</a>';
echo '<img src="spacer.gif" width=1 height=1 onLoad="javascript: location.href=\''.$SSL.$MainDir.$StudentPage.'?LAID=1&AID=50&CCID='.$_GET['CCID'].'\'">';
};
