Auto Submit Form & Back Button disable

Hi Zvonko,

Thanks for your reply. Tried that, still got the same error message.

I made the changes as instructed and uploaded them to a different directory,

http://www.bigwebhost.net/ee_examples/zvonko/firstpage.htm

as you can see the, the action of the form is not going through (same as before) and the back button is also not working.

this.href is supposed to be what?

I can not go back from the http 500 error page. Do you?

And that http 500 error is not because of JavaScript is doing anything. Your perl function refuses access.
I mean this as perl function:
<form name="form1" method="post" action="http://www.bigwebhost.net/ee_examples/script.pl">

You are right Michel, I did not test.

Correction:

2.) In this page http://www.bigwebhost.net/ee_examples/secondpage_code.php change this function:
function firstrun(){
 document.forms[0].submit();
 setTimeout("location.replace(location.href)",10);
 return false;
}

(also not tested and has also no meaning. It reloads the actual URL)
Anyway does the submit() response overwrite the page and loaction.

And put this history.go(+1) also in this page head:
http://www.bigwebhost.net/ee_examples/secondpage_code.php

Reading my post I noticed what nonsense I have posted.
Reloading of a php page which is automatically sending it submit() again and again!

The only good thing is that this did not work :-)

Zvonko,

When I click the link to the pages with your changes on - http://www.bigwebhost.net/ee_examples/zvonko/firstpage.htm and click submit it takes me straight to a 404 page and http://www.bigwebhost.net/ee_examples/zvonko/undefined is displayed in the address bar and I can't use the back button because of the history.go(+1); script on the first page.

I don't get the 500 error.

there's nothing wrong with the script, click it direct - http://www.bigwebhost.net/ee_examples/script.pl

Oh, and because I am one of top experts also on php ta (hello Michel) here my suggestion how to solve your resubmit problem.

Create a hidden field with a default value in the form of http://www.bigwebhost.net/ee_examples/zvonko/secondpage.php3
If the $_REQUEST['herenameofthehiddenfield']=="theDafaultValue" then do not print the <form> to the browser. That's all.

Sorry, now clicking the url on this page works. I copied the url before in browsers url field and got an 500 error.

But try this php <form> suppression method. This is the best way to prevent form resubmit.

Hi,

Thanks for your help, but I'm getting a bit confused with the last couple of posts fellas,

if we go back to the original problem, the script that i started with seems pretty good;

 location.replace(this.href);
 return false;

seems to be the area that causes the problems. I am open to all suggestions but i can't use PHP because the pages will be uploaded to an ASP server.

Ok, the let us focus on that.

Definitely is this.href not a valid object.
Perhaps does this assignment of an error to a window location prevent of back and forth of pages, but it is definitely an error.

So if you can confirm that history.go(+1) works for you, then is this the solution. Simply add that line in every page which is forbidden to be reached from successor pages.

The problem is not the back button, the actual script at the start of this post works fine for that, it deletes the second page from the browsers history and they can't go back to it, that's great. I just need to combine this with the autosubmit function for the form.

this seems to easy to be true, but it worked for me.
just add:
<SCRIPT LANGUAGE=javascript>history.go(+1);</SCRIPT>
to the head section of your page with the form on. users will not be able to go back. as soon as they do, they will just get taken back to the "after submit" page.

Andres101,

Thank you for your suggestion. That works, the information is not resent but the visitor remains locked on the "after submit" page, is there any way we can make the script say something like;

if history.go(+1) is not blank then
   history.go(-1)
end if

(i don't know how to write JS)

this way, when we went back to the form page it would take them back another page?

I really appreciate everyone's help.
