Hopefully, one of these should work :) Kirk > -----Original Message----- > From: Claudia [mailto:claudiasmt@sprynet.com] > Sent: Thursday, May 03, 2001 2:08 PM > To: php-general@lists.php.net > Subject: [PHP] using an array with form list values > > > I need to check that a form entry defined as an array contains a value > before initiating the foreach code in my script. > > I have my form field defined in my form as: > > <?php > print ' > <select > name="preferred_location[]"size="3" MULTIPLE> > <option value="Bermuda">Bermuda</option> > <option value="California">California</option> > <option value="Caribbean">Caribbean</option> > <option value="Carolinas">Carolinas</option> > <option > value="Florida-Atlantic">Florida-Atlantic</option> > <option value="Florida-Gulf > coast">Florida-Gulf > coast</option> > <option value="Florida-Pan handle">Florida-Pan > handle</option> > <option value="Hawaii">Hawaii</option> > <option > value="Mediterranean">Mediterranean</option> > <option value="Mexico">Mexico</option> > <option > value="S.Pacific/Autralia">S.Pacific/Autralia</option> > </select>'; > ?> > > And my script code as: > > foreach ( $preferred_location as $location ) > { > $msg .= "$location\n"; > } > > As long as the user selects at least one form value from the > list box, the > script processes without error.
