Checkboxes -> Database

[Adrian Schneider]

How would I go about doing this:

Insert checked checkboxes into database as a set (into text field), the only complication is the # of checkboxes is an unknown, as there is one for every 'player' in the player table (values are IDs). The names of the fields all are: positionXXX (where XXX = playeriD).

Sorry if this is yet another easy question, my brain shuts off sometimes.
