I’ve been attempting to adjust a mysql SELECT statement based on input from checkboxes.

  • 0

I’ve been attempting to adjust a mysql SELECT statement based on input from checkboxes. The php code collects the ticked checkboxes into an array, implodes them into a comma-separated list and then runs the query using an in statement (as was detailed here).

The query generated comes out as SELECT * FROM events WHERE Discipline IN (SJ,OTHER) which is a correctly formatted query as far as I can tell.

This shows up as an invalid query when run from the php code. When I run the query using phpmyadmin, I receive this message: 

#1054 - Unknown column 'SJ' in 'where clause'

I was wondering if anyone could tell my why that query is generating the error?

    Try putting quotes around the values in the IN clause:

    SELECT * FROM events WHERE Discipline IN ('SJ','OTHER')
