[FreeTrade] Adding New Feature

[Pat Dupuis]

Greetings all:   In my implentation of FreeTrade, I am attempting to add an extra feature which would allow the customer to customize a few of the basic templates and screens through online forms.  For all intents and purposes, we could call it an Online File Editor.  My approach is to add an extra form to the Admin Menu with a selection box which allows them to choose the file they wish to edit (page_top, page_bottom, help, welcome).  Once the file selection is submitted, I planned to use fopen and fgets to retrieve lines from the existing file and use a while loop to display all contents in a textarea box.  The customer would then be able to make changes to said file and resubmit.  I would then use fputs to rewrite the file.    My questions are as follows:   1.  Is my approach sound? 2.  I was thinking this could be acomplished with a couple of extra screens containing the file editing routines, without the use of an action file (seeing as most of the action files seem to be used for MySQL queries, updates, and such).  If my assessment is correct, can I create the file selection form using the "StartForm" function using only "screen", "post" and "name" values?  Or, is an action file necessary?   Any help or insight anyone could offer in this matter would be greatly appreciated.  Thanks in advance!   Regards,   Pat Dupuis
