PHP/MySQL Database Query From Checkbox Selections

i have written a php script that extracts data from a mysql table and turns it in a form full of checkboxes. what i need is a script that can build a query based on the users checkbox selections, then carry that query forward to the next form where the user will narrow down their search even more based on data from another table of selections. in other words, user selects a number of locations from page 1, then the user is presented with another page of location types and perhaps the user is presented with yet another page of checkboxes with even more selections. the query will be built from all of this data. i will supply the table structure(s). you will need to develop this on your own php/mysql setup. this should not take more than a few days to get the work returned to me and the bugs worked out i would think. i have attached a sample php script that retrieves the data from one of the tables, and builds the checkbox form. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform must be written in php and interface with mysql
