form submit redirect inside WP Plugin

[carbincopy]

Hi all, Please don't bash me. I have spent hours and hours, days and days. I can't get this stupid thing to work right.

The plugin is inside of wp which makes it own headers so making it almost impossible for me to understand.

I have tried Action"", Target"" and many things in between. I got it to open a new window but was same page not the page I was trying to get to load. I want it to open in same window with a new page.

My form has multi .php pages that collect data. But the first php page need to redirect to a new page and continue to submit data.

I did see this post that was something like my issue.

here is the page I have.

here is where I want to goto on submit.

I am not asking any one to build my site. I just really need direction in how to fix or find the issue.
I know it is a really simple issue to fix. Just I have no clue how it is done.

For all those who have the same issue as I did wanting a milti page form with redirect. Here is what I did to finally get my wp site widget-able form.

Please note: '/testing/' is where you put your url for your redirect ( since I am using wordpress the url is not a static .php or .html)
and if you wish to make all of your forms on different pages.
you would add this to all pages of your multi page form and change the url accordingly.
also you will want your form name set to your data fields these are mine. id="formElem" name="formElem"

<script type="text/javascript">
function submitForm() {

var targetURL = '/testing/';

document.aformiam.action = targetURL;

return true;
}
</script>

<form id="formElem" name="formElem" action="/testing/" method="post">

<!-- Your form goes between here -->

<!-- end form -->

<button id="btn_room_search" name="btn_room_search" type="submit" style="float:left" value="Send Form" onClick="return submitForm();" />Search</button>

Thanks again for viewing my problem, But I fixed it first. JC
