Double drop down menu with PHP?

[rbowen00]

Has anyone had any luck getting a double drop down menu to work with PHP? I can get the menu - which is written in javascript to work, but I can't figure out how to pass the value of what the user selects to PHP.

What I want to do is have a small online address book for the school district I work for. Users visiting our page would be able to select from searching by Last Name, Department or Building. What I wanted was if the user selects Department a menu opens up with all the departments listed, same for buildings.

Here is the page with the javascript I am using. It simply redirects the user to a URL based on their selection.

My only thought is to pass the selection through the URL, but then I have to turn on register_globals and that makes me nervous.

Any thoughts/suggestions would be appreciated.

Thanks,

How about putting the drop down menu's into a form?

Something like this maybe:

<form blah blah>

<select name="name">
<option value=0>--No Selection--</option>
<option value=1>Smith</option>
...
</select>

<select name="dept">
<option value=0>--No Selection--</option>
<option value=1>Dept 1</option>
...
</select>

<select name="building">
<option value=0>--No Selection--</option>
<option value=1>Building 1</option>
...
</select>

<input type="submit" value="Go" name="submit">

</form>

Then in your php file, have something like,
if (building>0) { search by building }
else if (name>0) { search by name }
else if (dept>0){ search by department }
else { error: nothing selected }

Did that help?
