    OVERVIEW
    --------

        NOTE...This extension will not work with the CVS version of PME

    calPopup extends the standard phpMyEdit class to allow
    a calendar popup helper to be put on any text field.
    This extension uses the free jsCalendar code from
    http://dynarch.com/mishoo/calendar.epl website.
    
    REQUIREMENTS
    ------------

    The requirement is a properly installed jsCalendar script.
    All browsers supported by jsCalendar are supported by this
    extension.

    USAGE
    -----

    This extension enables the display of a popup calendar selection
    against selected fields.
    
    In order to use it, you should:

    1. Load the jsCalendar scripts in the <head>...</head> section of
       your phpMyEdit calling program, substituting the correct paths:

       <script type="text/javascript" src="js/calendar.js"></script>
       <script type="text/javascript" src="js/lang/calendar-en.js"></script>
       <script type="text/javascript" src="js/calendar-setup.js"></script>

    2. Choose your preferred jsCalendar CSS file (see jsCalendar
       documentation) and add the following in the <head>...</head>
       section of your phpMyEdit calling program, substituting the
       correct path:
        
        <link rel="stylesheet" type="text/css" media="screen"
                href="css/calendar-system.css">

       NOTE: To avoid an unwanted side effect in the CSS style
       produced by phpMyEditSetup.php, add a 'width:auto' property
       into the '.calendar table' entry in your selected jsCalendar
       style sheet.

    3. Call to phpMyEdit-calPopup.class.php instead
       of phpMyEdit.class.php.

       Example:

       require_once 'extensions/phpMyEdit-calpopup.class.php';
       new phpMyEdit_calpopup($opts);

    4. Add 'calendar' parameter to the field definitions where you
       want a calendar popup in your phpMyEdit calling program.

       Example:

       $opts['fdd']['col_name'] = array(
         'name'     => 'Column',
         'select'   => 'T',
         'options'  => 'ACPVD',
         'required' => true,
         'calendar' => true
       );

       This is will display a button next to the field which pops up
       a calendar when clicked. If that field has a 'strftimemask'
       parameter set, it will use this for the date format.
        
       For more advanced usage, you can set the 'calendar' parameter
       to an array of valid jsCalendar Calendar.setup options
       (see jSCalendar document for details). Note that not all
       of these options make sense to use in phpMyEdit, and some
       of them will actively break the function.
        
       Example:
        
       $opts['fdd']['col_name'] = array(
         'name'     => 'Column',
         'select'   => 'T',
         'options'  => 'ACPVD',
         'required' => true,
         'calendar' => array(
           'ifFormat'    => '%Y/%m/%d', // defaults to the ['strftimemask']
           'firstDay'    => 1,          // 0 = Sunday, 1 = Monday
           'singleClick' => true,       // single or double click to close
           'weekNumbers' => true,       // Show week numbers
           'showsTime'   => false,      // Show time as well as date
           'timeFormat'  => '24',       // 12 or 24 hour clock
                   'label'       => '...',      // button label (used by phpMyEdit)
           'date'        => '2003-12-19 10:00' // Initial date/time for popup
                                               // (see notes below)
         )
       );

    NOTES
    -----

    1. The popup will normally set the initial value to the current
       field value or to current date/time. 'date' option will always
       override this, even if there is a current date/time value
       in the field. If you want a default value only if the field
       is currently empty, use the phpMyEdit 'default' option.

    2. Only the options listed above may be set by the user, any other
       options will be ignored.
