MySQL table data question?
How should my Mysql table data look like for a single checkbox that checks and see if the user has said yes if its clicked or no if its not?
开发者_JS百科Here is the checkbox.
<input type="checkbox" name="yes" id="yes" value="yes" />
I was wondering how would I add it to the following table.
CREATE TABLE IF NOT EXISTS `vote` (
`counter` int(8) NOT NULL default '0',
`value` int(8) NOT NULL default '0'
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
Use the TINYINT(1) datatype. I believe it is a synonym for BIT.

Also, typically an unchecked checkbox will not submit anything, so you will need to check for null or nonexistent values.
You'd probably want to use an ENUM
or a BOOLEAN
.
See the documentation for more details.
Just make it an INT. Someday you might need to change it from a "Yes"/"No" to a "Yes"/"No"/"Maybe" and then you won't have to change the datamodel.
I view a checkbox as the same thing as a select-choice; just with only 2 choices (3 if you include "No choice yet made") so I treat it as such and stick with INT.
