To enable multiple selections, you add the multiple attribute and add square brackets to the end of

the name attribute as shown in the following code. The multiple attribute enables the user to select
multiple options with his operating system’s shortcut using the Shift, Control, or Command keys.
The square brackets on the name attribute create an array to hold the multiple selections. The size
attribute determines how many options should be displayed at a time.

    <label for=”interests”>What do you like?</label>
    <select id=”interests” name=”interests[]” multiple=”multiple” size=”3”>
    <option value=”0”>Reading</option>
    <option value=”1”>Whitewater boating</option>
    <option value=”2”>Music</option>
    </select>
    </fieldset>
    <fieldset>
    <input name="contactForm" type="submit"  value="提交"/>
    <input type="reset"  value="重置" /> type类型，submit，reset，button的value值是显示的值，与其他标签的value属性不同

You can also send hidden values. “Hidden” just means the form fi eld is not displayed in the form. It
is still displayed in the URL. Use the <input> tag with type=”hidden” to specify hidden values:
<input type=”hidden” name=”id” value=”12345” />

<input type=”hidden” name=”id” value=”12345” />    </fieldset>
