I am trying to create a form search with two drop down selects where the value chosen in the first will update the value in the second. The first drop down is a Product Line - the second drop down is a U.S./Canada list. So user would choose which product they are interested in, then choose the State/Canadian Provice where they live. In the admin side I just have a Dealer record that has each product with the State/Canadian multiselect as each Dealer can have either of 5 product lines and serve different states. This might not be the best way to do it, but it is what I came up with. I just need to figure out how to take the Product Line selected and pass that to the State/Province value to search by.

<form method="POST" action="/wilsontrailer.php">
<input type="submit" name="submit" value="Search">
<select name="" id="">
<option value="gooseneck">Gooseneck</option>
<option value="grain">Grain</option>
<option value="livestock">LIvestock</option>
<option value="flatbed">Flatbed</option>
<option value="belt">Belt</option>
</select>
<select name="gooseneck_keyword" id="state">
<option>CHOOSE OPTION</option>
<optgroup label="United States">
<option id="AL" value="AL">Alabama (AL)</option>
<option id="AK" value="AK">Alaska (AK)</option>
<option id="AZ" value="AZ">Arizona (AZ)</option>
<option id="AR" value="AR">Arkansas (AR)</option>
<option id="CA" value="CA">California (CA)</option>....
Wouldn't it be fairly easy to just do a variable on the first select that would be passed into the value of the second?

Hi petejdg,

We don't have any easy code for this, but I think what you are looking for is called "chained selects".

Here's a google link: http://www.google.com/search?q=chained+selects

There's a number of scripts that let you update one select pulldown from another.

Hope that helps!

Dave, I was able to get the select drop downs working correctly with your link. Thanks. Now my dilemma is how to actually make the search work correctly, but I don't even know if it can. I thought this would be fairly simple but seems definitely not. Since it is pulling my list - I can't tell any of the form variables. I don't know if anyone can help or how bad of a custom job this would be?

Hi,

When your form is submitted, are you able to get the values that were selected from your drop down boxes?

Good question. Since they aren't populating the the html I don't know. But I am pretty sure it won't work as the value of the main select is being set - I assume that has to be a variable to pull in my search params like "gooseneck_keyword". I am attaching the files but in the wilsontrailersearch.php the coding is:<select name="trailertypes" style="width:160px;"></select> and I assume the trailertypes has to be one of my trailer searches with _keyword???

Hi,

When your form submits to wilsontrailer.php, you should have access to two variables inside the $_REQUEST array:

$_REQUEST['trailers']
and
$_REQUEST['trailertypes']

You could then use these to create your search. If the section you're searching against has fields called trailers or trailertypes, this search can be done automatically. If not, you'll need to manually create your WHERE clause.

Hope this helps

Thanks... but I don't really know php so I think this is now way over my head.
