inserting a variable in my form action

Copy linkTweet thisAlerts:

Hey all,

I’ve got this form.

<form name=”viewPage” method=”post” action=”index.html?var=_______”>
<input type=”hidden” name=”var”>
</form>

What I basicly want to do is display the variable “var” where there are some underscores. I have done this with PHP but since its server side it displays the value of the precedent submit. I want to somehow enter the var info with javascript?

Any idea on how to go about to do this?

Thanx,
Pat~

If you want to submit all form variables to the url, instead of just one, you can do this:

[code=php]
<form name="viewPage" method="get" action="index.html">
<input type="hidden" name="var">
</form>
[/code]

Instead of posting the information, the browser will append all of the form fields to the URL. If you want to only do this with one form field, but have the others go on as normal, you can do this:

[code=php]
<form name="viewPage" method="post" action="index.html" onsubmit="this.action += '?' + this.var.value">
<input type="hidden" name="var">
</form>
[/code]

Success!
