Is there a way to pass variables w/o a submit button?

dalhism

I was wondering if it was possible to POST variables to more than one form at a time.

If not, is it possible to POST variables to a form, without submitting them through a form using a submit?

I am passing from one form where the user submits information (create_form.php) to a second form where calculations are worked on the page (make_form.php) and then I want them to go to a third page to display it (preview.php).

The part that makes it difficult is that the display page is really a popup window that will have frames in it.

I was thinking of just handing the information along, but I don't know how.

Any help would be greatly appreciated.
Thanks.

A workaround to do this is to have a script that has a form and hidden inputs in it. Then at the bottom of the page (and outside the <form></form> tags) you have the following:

<script>
document.forms.formname.submit()</script>

Then you just have all the variables that you want pass as hidden inputs. I did this to pass shopper details to worldpay and it works a treat.

Thanks, piersk, but I still can't get it to work.

have a script that has a form and hidden inputs in it

Does this mean I need javascript and I need to put the hidden form in between the script tags?

Then you just have all the variables that you want pass as hidden inputs.

How do I do this? I really need some guidance. This is what I managed out of the help given earlier.

Here's my form with hidden values... the PHP variables on the page are $new_array and $new_array2.

echo"<FORM name=\"sendVars\" method=\"post\" ACTION=\"preview.php\">";
	echo"<INPUT TYPE=\"hidden\" NAME=\"new_array\" VALUE=\"$new_array\">";
	echo"<INPUT TYPE=\"hidden\" NAME=\"new_array2\" VALUE=\"$new_array2\">";
	echo"</FORM>";

I just don't get how it works.

Here's my script with the submit thing appearing after this form...

<script>
//NEW javascript to pass variables...<script>document.forms.formname.submit()<./script>
document.forms.sendVars.submit();
</script>

From what I have written earlier, I have this code in the second page, the make_form page.
I really appreciate any help with this problem. It would be great to get past this. Thanks.

Which bit isn't working? Have you tried stopping the page with the hidden form on so that you can check the html to make sure all the values are being passed?

I'm not sure how to use the hidden fields in the form. Also, can you explain the logic behind how the javascript function works? I'll continue working on it. I appreciate all the help.
