History.Forward() - Value ??

[stuartc1]

Hi,

I know this is a javascript question on a PHP Forum, but what the hell. It is related to PHP a little 🙂

I have a problem with my PHP application - when a feature has been completed (like a record removed for a database), then the user click the back button (those bloody users🙂), the script attempts to remove the record again. This is not the best, in fact its bad and i dont want it. What I do want is the browsers back button to be de-activated, that would be good.
I have read many articles and searched around for many moons, but it seems there is no real good answer. The best I can get is to use:

<SCRIPT language="javascript">
	window.onback=history.forward();
</SCRIPT>

This will put the user back to the current page if the hit back... this is good, but not good enough. I want an alert to say 'Please do not use the back button'.
My Question then (at last): is it possible to get a value of history.forward() ? either the count or true or false ?

any help will be fantastic.

Why not do something a little different instead of relying on Javascript, which the user could have disabled anyway, leaving your code to delete the record over again....

Suggested plan:

From the possible submit form where the user picks the details to be deleted, a small popup appears for a while, telling them that they are deleting something, the details of which are passed by the previous form. If you are using sessions, register a variable that will identify that a record has been deleted at the end of the delete record code.

Then at the beginning of the popup page code, use something like

if ($deletedrecently=='yes'){
   echo "You just deleted that - DONT USE THE BACK BUTTON !";
   exit;
}

Which will let them use the back button still, yet give you the ability not to try and delete the record again...

Your probably right, I should have done something like this. But I have went to far with this to make these types of changes everywere (I dont have the time).
Cheers anyway.
