OK I have fixed the errors (I regularly seem to get things working shortly after posting to the support forums), just need to get the filtering to add to the results each time more checkboxes are ticked. For example, if I am filtering by postcode and the postcode checkboxes are populated by a MySQLi recordset, I have 1 binding set to filter the postcodes but if more than 1 checkboxes are ticked, it should add to the results. Can you please advise how this can be achieved?
I understand that if I have different filters in place, eg. by postcode, by price, by star rating etc... then I would just add the additional bindings and add to the SQL query but how do you achieve with 1 binding on dynamically generated checkboxes?
