checkbox value from a form to mysql query

 10:23 am on Apr 6, 2011 (gmt 0)

i have (amongst other options) 3 checkboxes

the form result is sent to a php page which queries the database and all works fine

trying to incorporate the 0/1 options is becoming a nightmare

the table:

name | area | option1 | option2 | option3

joe | north | 1 | 0 | 0
bill | south | 0 | 1 | 1
fred | north | 1 | 1 | 0

the option are from the checkboxes

the main search is on area from a select option in the form but i need to pick up if any of the options are ticked

if someone wants north & option2 :


if i use radio boxs or a select then the 0 values of the options get picked up ie


but in my query how do i only select rows where option2=1

SELECT * FROM `tableName` WHERE `option2` = 1;

Two things; firstly, ensure that if the option fields are only holding 1 or 0, set them up using a the enum() option to avoid any erroneous insertions..

Secondly, remember that fields that are numerical will not need to have quotes around them, if you do, this will cause all sorts of errors later on.

Hopefully that will answer your query.

sorry, i shouldve clarified more - the problem is that the query is coming from a get

so i have WHERE option2=" . $_GET['option2'] . " etc

i need to be able to filter out the =0 ones that get sent in the url

or if i do it on checkboxes how do i filter out in the query -

option1=" . $_GET['option1'] . " OR option2=" . $_GET['option2'] . "

this fails on the checkbox one since only boxes that are ticked send the variable
