How It Works
The Web form, registration_multi.html, is largely similar to the previous registration.html
page. However, this form contains a multi-select list box (favoriteWidgets) and two checkboxes
with the same name (newsletter). Because these controls are capable of sending multiple values, two
empty square brackets ([]) are appended to the field names:
<label for=”favoriteWidgets”>What are your favorite widgets?</label>
<select name=”favoriteWidgets[]” id=”favoriteWidgets” size=”3”
multiple=”multiple”>
<option value=”superWidget”>The SuperWidget</option>
<option value=”megaWidget”>The MegaWidget</option>
<option value=”wonderWidget”>The WonderWidget</option>
</select>
<label for=”newsletterWidgetTimes”>Do you want to receive our
‘Widget Times’ newsletter?</label>
<input type=”checkbox” name=”newsletter[]” id=”newsletterWidgetTimes”
value=”widgetTimes” />
<label for=”newsletterFunWithWidgets”>Do you want to receive our
‘Fun with Widgets’ newsletter?</label>
<input type=”checkbox” name=”newsletter[]” id=”newsletterFunWith
Widgets” value=”funWithWidgets” />
