Plain calendar

Hello, Tell me please, how can I make the calendar be always displayed on the screen, allowing the user to select a date? Thanks

Just 2 points
  1. If you get some error messages when you first copy the calendar folder into your extensions folder. Make sure to set the right permissions (in Linux).

  2. When you use it with CActive form, make sure not to include the array("id"=>"idoffield") and to set the 'inputField' config parameter to be the auto generated id of the field you refer to (this is usually FormName_fieldName).

Thank you

change default date

How to change default date in this extension? It is displaying current date by default right now

I want to change it with my custom date as default date. How can I do this?

Looks like a datepicker not a calendar

a calendar is more like google's calendar, whereas a datepicker is for picking a date in a form field

Powerfull and easy to integrate extension!

Congrats on the extension! Super easy to use and a very powerful functionality ... For those that are in a hurry and getting the error, about the undefined variable, just delete ('skin'=>$skin, 'stylesheet'=>$style) to use the default styling.

Congrats again!

Language Property


I think you shouldf add the following code at ca. line 509 in SCalendar.php:

if(isset ($this->_language)) $prop .= "language : '$this->_language',\n";

Is It a bug?

Hi, What is the value of the $style and $skin you use? Also check the jscalendar's home page to see if the bug happens there too. http://www.dynarch.com/static/jscalendar-1.0/simple-1.html

If you have any other questions please post them in the forum thread http://www.yiiframework.com/forum/index.php?/topic/2337-extension-calendar/

is it a bug?

Hey, guys,

I'm using the following code:

<?php echo CHtml::activeLabelEx($model,'promotionDateStart'); ?> <?php echo CHtml::activeTextField($model,'promotionDateStart',array('id'=>'promotionDateStart')); ?> <?php echo CHtml::image(Yii::app()->baseUrl."/images/site/calendar.jpg","calendar", array("id"=>"ds_button","class"=>"pointer")); ?> <?php $this->widget('application.extensions.calendar.SCalendar', array( 'inputField'=>'promotionDateStart', 'button'=>'ds_button', 'skin'=>$skin, 'stylesheet'=>$style, 'ifFormat'=>'%Y-%m-%d', 'range'=>'[2000,2050]', 'cache'=>true, //'showOthers'=>false, //'showsTime'=>false, //'timeFormat'=>'24', 'language'=>'br', )); ?>

Yii 1.0.9, Linux, Firefox 3.5

The calendar object is shown fine, but 17th, October (today) is shown twice, in Saturday and Sunday...and it changes all the rest of month...any idea on how to solve this bug?

To use Step Parameter

If you want to manage the 'Step' parameter that is contemplated in DHTML Calendar for change the step between years in the drop down list (default=2) you must make these changes to SCalendar.php:

In the begin add to the other parameters: /* @var $_step Integer private $_step;

Add this new function: /*** * @param integer $step */ public function setStep($step) { if(is_numeric($step) && ($step >-1)) { $this->_step = $step; } else { $this->_step = 2; } }

Add in createMarkup function: if(isset ($this->_step)) $prop .= "step : $this->_step,\n";

Error in SCalendar.php for boolean parameters

I found that all the boolean parameters causes a javascript error if they are used (true or false), they are: singleClick, weekNumbers, showsTime, electric, cache, showOthers The problem is that they must be passed to js surrounded by '' So you should substitute in the createMarkup function of SCalendar.php the 6 rows of the above parameters from:

if(isset ($this->_PARAMETER))     $prop .= "PARAMETER       :  $this->_PARAMETER,\n";


if(isset ($this->_PARAMETER))     $prop .= "PARAMETER       :  '$this->_PARAMETER',\n";

There was an error in the SCalendar.php You should change line 486 from

if(isset ($this->_flatCallback))  $prop .= "flatCallback    : '$this->_flatCallback',\n";


if(isset ($this->_flatCallback))  $prop .= "flatCallback    : $this->_flatCallback,\n";

Then the calendar has to be a flat one Then use this code

<script type="text/javascript">
  function dateChanged(calendar) {
    // Beware that this function is called even if the end-user only
    // changed the month/year.  In order to determine if a date was
    // clicked you can use the dateClicked property of the calendar:
    if (calendar.dateClicked) {
      // OK, a date was clicked, redirect to /yyyy/mm/dd/index.php
      var y = calendar.date.getFullYear();
      var m = calendar.date.getMonth();     // integer, 0..11
      var d = calendar.date.getDate();      // integer, 1..31
      // redirect...
      window.location = "/" + y + "/" + m + "/" + d + "/index.php";
<div id="calendar-container"></div>
 <?php $this->widget('application.extensions.calendar.SCalendar',
        'flat'=> 'calendar-container',

My BAD, this version is under LGPL

Now wondering how to use this?

function dateChanged(calendar) {

if (calendar.dateClicked) {

  var y = calendar.date.getFullYear();

  var m = calendar.date.getMonth();   

  var d = calendar.date.getDate();    

  window.location = "/" + y + "/" + m + "/" + d + "/index.php";

The "better" date picker

This "calendar" is much better in my opinion then the only other viable alternative, jui.EDatePicker.

The EDatePicker although useable with some minor code modifications, is really very basic with a crude graphical user interface.

This calendar however offers EVERYTHING and it works great without any modifications. The graphical user interface is intuitive and very advanced as well as easy to control. Thanks!
