How to pass variables in php using GET without type?
<pre><code> &lt;form method="get" action=..... &gt;

                      Food &lt;input name="food" type="text"  size="1" /&gt;
                  Pizza &lt;input name="pizza" type="text"  size="2" /&gt;
                  Drink &lt;input name="drink" type="text" size="2"/&gt;           
</code></pre>

<p>Now I want to pass a third variable which is a concatenation of food+pizza+drink in the URL
I don't want to create a new <code>&lt;input name="total" type="text" size="2"/&gt;</code></p>

<p>Is this possible?</p>

<p>EDIT:</p>

<p>I want to do it before submitting the values.</p>

<pre><code>I will have a url like
 http://www.abc.com/&amp;food=tasty&amp;pizza=cheeze&amp;drink=pepsi
I want the url to be
 http://www.abc.com/&amp;food=tasty&amp;pizza=cheeze&amp;drink=pepsi&amp;total=tastypizzacheezepepsi
</code></pre>
