%SHORTDESCRIPTION%

---++ Introduction

The !DatePickerPlugin handles an input field with a pop-up calendar to select a date for use in TWiki forms and TWiki applications. The plugin is based on the [[http://www.dynarch.com/projects/calendar/old/][Mishoo JSCalendar]], a DHTML pop-up calendar. The date format can be customized.

%X% __ATTENTION:__ This plugin replaces the JSCalendarContrib. The !DatePickerPlugin and older versions of the !JSCalendarContrib do not coexist. Before using the !DatePickerPlugin, uninstall the !JSCalendarContrib, or upgrade the contrib to version 2012-12-12 or later.

---++ Use Date Picker in !TWikiForms

This package adds a =date= type to %SYSTEMWEB%.TWikiForms:

| *Type* | *Description* | *Size* | *Value* |
| =date= | %IF{ "'%BASETOPIC%'!='%TOPIC%'" then="<img src='%PUBURLPATH%/%WEB%/DatePickerPlugin/screenshot-small.png' alt='screenshot-small' width='150' height='127' align='right' style='margin-left:15px;' /> "}%Text input field and a button next to it to pick a date from a pop-up calendar. The date can also be typed into the text box. %IF{ "'%BASETOPIC%'='TWikiForms'" then="[[DatePickerPlugin][See details]]." }% | Text box width in number of characters | Initial (default) date |

Example form definition:

| *Name:* | *Type:* | *Size* | *Values:* | *Tooltip message:* |
| Start date | date | 12 | %SERVERTIME{$year-$mo-$day}% | Select start date |

---++ Use Date Picker in HTML Forms

You can also use the date picker directly in your HTML forms, without having to write any code. Just include this in the topic text:
<pre>
&lt;form action="..."&gt;
%<nop>DATEPICKER{ name="Start_date" value="%SERVERTIME{$year-$mo-$day}%" }%
&lt;form&gt;
</pre>
This will show an HTML input field named "Start_date" and a button to popup a calendar to select a date.

%INCLUDE{ "VarDATEPICKER" section="parameters" }%

Test: (this only works if the !DatePickerPlugin is installed and enabled)

<form>
%DATEPICKER{ name="Start_date" value="%SERVERTIME{$year-$mo-$day}%" }%
</form>

---++ Detailed Documentation

%TWISTY{
 mode="div"
 showlink="Show details %ICONURL{toggleopen}% "
 hidelink="Hide details %ICONURL{toggleclose}% "
}%


Read [[%ATTACHURL%/doc/html/reference.html][the Mishoo documentation]] or
[[%ATTACHURL%/index.html][visit the demo page]] for detailed information 
on using the calendar widget.

This plugin includes the following function to make using the calendar
easier from other TWiki plugins:


---+++ renderForEdit

=TWiki::Plugins::DatePickerPlugin::renderForEdit( $name, $value, $format [, \%options] ) -> $html=

This is the simplest way to use calendars from a plugin.
   * =$name= is the name of the CGI parameter for the calendar
     (it should be unique),
   * =$value= is the current value of the parameter (may be undef)
   * =$format= is the format to use (optional; the default is set
     in =configure=). The HTML returned will display a date field
     and a drop-down calendar.
   * =\%options= is an optional hash containing base options for
     the textfield.

__Notes:__
   * The CSS and Javascript are added if needed, e.g. the =addToHEAD()=
     function does not need to be called.
   * No output is shown if =$name= is empty or undef, but the CSS and
     Javascript are loaded if needed. This can be used to preload the
     CSS and Javascript with a parameterless =%<nop>DATEPICKER{}%=
     variable.

Example:
<verbatim>
use TWiki::Plugins::DatePickerPlugin;
...
my $fromDate = TWiki::Plugins::DatePickerPlugin::renderForEdit(
   'from', '2012-12-31');
my $toDate = TWiki::Plugins::DatePickerPlugin::renderForEdit(
   'to', undef, '%Y');
</verbatim>


---+++ addToHEAD

=TWiki::Plugins::DatePickerPlugin::addToHEAD( $setup )=

This function will automatically add the headers for the calendar to the page
being rendered. It's intended for use when you want more control over the
formatting of your calendars than =renderForEdit= affords. =$setup= is the name
of the calendar setup module; it can either be omitted, in which case the method
described in the Mishoo documentation can be used to create calendars, or it
can be ='twiki'=, in which case a Javascript helper function called
'showCalendar' is added that simplifies using calendars to set a value in a
text field. For example, say we wanted to display the date with the calendar
icon _before_ the text field, using the format =%Y %b %e=
<verbatim>
use TWiki::Plugins::DatePickerPlugin;
...

sub commonTagsHandler {
  ....
  # Add styles and javascript for the date picker & enable 'showCalendar'
  TWiki::Plugins::DatePickerPlugin::addToHEAD( 'twiki' );

  my $cal = CGI::image_button(
      -name => 'img_datefield',
      -onclick =>
       "return showCalendar('id_datefield','%Y %b %e')",
      -src=> TWiki::Func::getPubUrlPath() . '/' .
             TWiki::Func::getTwikiWebname() .
             '/DatePickerPlugin/img.gif',
      -alt => 'Calendar',
      -align => 'middle' )
    . CGI::textfield(
      { name => 'date', id => "id_datefield" });
  ....
}
</verbatim>

The first parameter to =showCalendar= is the id of the textfield, and the 
second parameter is the date format. Default format is ='%Y-%m-%d'=.

The =addToHEAD= function can be called from =commonTagsHandler= for adding
the header to all pages, or from =beforeEditHandler= just for edit pages etc.
