/*    phpMyEdit intro {{{ */
/*
    This is a generic table editing program. The table and fields to be
    edited are defined in the calling program.

    This program works in three passes. Pass 1 (the last part of
    the program) displays the selected MySQL table in a scrolling table
    on the screen. Radio buttons are used to select a record for editing
    or deletion. If the user chooses Add, Change, or Delete buttons,
    Pass 2 starts, displaying the selected record. If the user chooses
    the Save button from this screen, Pass 3 processes the update and
    the display returns to the original table view (Pass 1).

    version 3.5 - 06-May-01
    
    important variables passed between calls to this program
    
    $fm     first record to display
    $inc    no of records to display (SELECT ... LIMIT $fm,$inc)
    $fl     is the filter row displayed (boolean)
    $rec    unique id of record selected for editing
    $qf0,.. value of filter for column 0
    $qfn    value of all filters used during the last pass
    $sfn    sort field number (- = descending sort order)
    $operation    operation to do: Add, Change, Delete
    $message    informational message to print
    $filter filter query
    $sw     filter display/hide button

    $prev, $next  navigation buttons
    $labels narrative for buttons, etc

    Conversion to PHP Classes by Pau Aliagas (pau@newtral.com)

    ToDo:
    'Copy' button 

    Aggregates:
    nonworking code commented out in list_table()
    doesn't work yet

    Query Building:

    Multi-Part Date Handling:
    Finish converting date handling to internal date handling functions
    Abstract date field gathering to get rid of _many_ redundant lines of code
    There was some kludged fix for dateformat'ting where '%'s are removed
    Better support for more date format macros
    Better documentation for valid date format macros

    Multi-Language support:
    Finish implementing language labels
    Use browser-supplied language if available
    Allow programmer override in setup.php generated .inc file
    Add 'Search' and 'Go!' to labels array

    Data Validation:
    Expand JS field validation to match JS regexes
    Create PHP field validation to match PHP regexes

    Change Tracking/Notification:
    Add change notification (via mail()) support
        Don't die if mail() not available

    CSS:
    Document & solicit feedback to standardize class names

    Even/Odd Coloring:
    Move to CSS
    Put values in setup.php generated file

    Timer Class:
    Solicit user input whether to put timer class into this lib
