I'm still trying to understand what you really want to do, but whatever it is, I'm sure there's a better way than having script-internal variable expressions stored in string values in a database, and having the script 'eval' those strings.

I think a "dynamic form-maker" is a sensible thing to build, but the typical approach for that would be a tool that allows the author/admin person to create a page layout with some inventory of elements to present the end-users with suitable instructions, input methods, and displays of results.

Throughout the authoring process, maintain a set of labels (simple strings) for identifying the specific inputs-from and outputs-to the end-user. The labels can be tracked in the database in whatever way makes sense for the application; the script can use the labels as hash keys for storing whatever the script needs for mediating between the user and the database - subroutine refs, data structures, query strings, etc.
