If you are about to create a graph, the best option i would suggest is the jqbargraph.

If you have two datepicker in one form and you want that a date of from date shold be minimum date of todate then put following code in Cjuidatepicker widget options array:

'onSelect'=>'js:function(selected) {
$("#HostelRoomStatusMaster_room_status_master_end_date").datepicker("option","minDate",selected);
				}',

Changing the way a CGridView is rendered from the configuration file, or through behaviors specified at the moment it is used, is handy to extend a CGridView without creating tons of different classes for it. I am surprised that this is not in the default implementation, so I made my default CGridView implementation.

I guess this is a tip on how to execute some code before every action in a controller, because I will tell you how I did it and maybe you can use the idea in your project.

find doubletts by db fields. in this example i will check doublets for 3 tabelfields (col1,col2,col3). so i will get a subquery with the condition, select and grouping of the tablefields. the having with COUNT() > 1 means: find all records more then one result.

$model=new MyModel('search');
$model->unsetAttributes();

When using CListView to display multiple views next to each other, we can use the $index variable inside the viewFile to achieve this. As far as i know there is no extension or out-of-the-box functionality for this, so we need to apply a little hack:

This is not actually Yii involved.

Sometimes writing views like

1. Create an Active Record Behavior that builds the criteria for the search() method and attach it to your model
2. Modify the search() method of the model to merge the behavior's criteria in with the rest of the searchable attributes

After Installing Yii Users and Rights to Newly Created Yii app we have to assign dynamic roles to a user at the time of user creation .

Hi Friends,

So you want to use CForm (form builder), but need to preload dropdowns in a form? It's simpler than it seems.
You got your CFormModel, CForm and the actual Form, right?
Let's say you have the typical State -> City dependent dropdowns, so you would want to load the from with the State and City selected.

some times we want to show the serialNo on cgridview .

Hi Friends, Hi Friends, Some common question is difficult to how to create the layout on yii and how to work

I saw many posts that community newbie is confuse in image/photo upload with random name. so I post this topic covering all useful things regarding to image/photo upload(not covering image attribute related functionality)

I wanted to implement a widget that could refresh itself through Ajax without refreshing the whole page. CGridView and CListView are excellent examples of such widgets.

As we know Using crud generator creates menu items in view files (for each view file have a varius menu items)

1. Create an Active Record Behavior that builds the criteria for the search() method and attach it to your model
2. Modify the search() method of the model to merge the behavior's criteria in with the rest of the searchable attributes
3. Modify the _search form view to add the date range inputs

There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.
