I have the following drop down boxes for people to select on a form. I would like to make sure when they submit the form that at least on of the drop down boxes has a value selected. As of right now when they submit I get NONE in my email and database. Could someone please help me out with how to do this in PHP.
<select name='local[]' multiple size="1" style="font-size: 8pt">
<option selected value="NONE">NONE</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
</select>
<select name='foreign[]' multiple size="1" style="font-size: 8pt">
<option selected value="NONE">NONE</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
</select>
<select name='modern[]' multiple size="1" style="font-size: 8pt">
<option selected value="NONE">NONE</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
</select>
Thanks in Advance
