Why won't my form with drop downs transmit data? (easy)

Hello.  When a user makes a choice in both select boxes and clicks "submit",  the data should be submitted to welcomeCar.php.  Except that it is not working.  What do I need to change?

choices.php

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The above is almost correct except that HTML uses double quotes, not single quotes. :-)



<select name="one">
    <option value="volvo">Volvo</option>
    <option value="saab">Saab</option>
    <option value="mercedes">Mercedes</option>
    <option value="audi">Audi</option>
 </select>

<select name="two">
    <option value="volvo" name="two">Volvo</option>
    <option value="saab">Saab</option>
    <option value="mercedes">Mercedes</option>
    <option value="audi">Audi</option>

Almost but you had too many 'names'.  Only the <select>s should have names for this purpose.

Any HTML form input tag that omits the name attribute will be omitted from the request to the action script.  You can use var_dump($_REQUEST) to verify this.  In addition to this, which makes some kind of sense to me, there is the issue of checkboxes and radio buttons (and the part about checkboxes and radio buttons does not make sense to me).  There is no default value for these form elements.  An unfired checkbox is simply absent from the request, as if it had not been given a name!  So if you have a named input type=text you've got something in the request, even if it is only an empty string.  But with input type=checkbox you might have something useful or you might just have an undefined index.  D'Oh!  As you might expect this causes a lot of head-scratching.
