You should use checkboxes for fields whose values can be one or more of a predefined set of values. By giving each checkbox the same NAME attribute, the data will be sent as a list of values if multiple boxed are checked. Like text fields, the checkbox uses the <input> tag, with a TYPE of “checkbox”:
<input type="checkbox">
Each checkbox should also have a VALUE attribute. This is the data that will actually be sent to PonyExpress for your checkbox field, not the text visible on the page. To have a checkbox default to an already-checked state, add the “CHECKED” keyword inside the INPUT tag.
For example:
Please contact me by:<br>
<input type="checkbox" name="contact" value="email"> Email <br>
<input type="checkbox" name="contact" value="phone"> Phone <br>
<input type="checkbox" name="contact" value="snail"> U.S. Mail <br>
<input type="checkbox" name="contact" value="none" checked> Don't contact me <br>
Produces the following output:
Please contact me by:
Phone
U.S. Mail
Don’t contact me
