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();

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 .

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)

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.

Hi friends,

Hi all,

Sometimes new Yii guys face problem to manage dependent dropDownList using AJAX. I am going to discuss an easy solution about this issue.

When you're filling up a form of a CActiveRecord (using CActiveForm for example), usually you'll construct your code so that in case of validation error you'll get back the form with the error displayed back to you, typically when CActiveForm.errorSummary() is used. This is how its done by Gii.

I recently worked on updating the content of a gridview based on the selection of a dropdown menu. I thought I should share it in the forum...

// In Yii 1.x $form = $this->beginWidget('CActiveForm', [

'id' => 'order-search-form',
'method' => 'get',

]); echo $form->textInput($searchModel, 'id'); echo CHtml::submitButton('Find', ['class' => 'btn btn-primary']); $this->endWidget(); `

Hi Friends,

This topic is related with langhandler extension

There are cases that you want to make an ajax request to another server and get the results.

Yii has a neat "trick" that will assign default values to new CActiveRecords. When performing a search() though, this is pretty annoying as they automatically apply as filter values.

Efficient coding with Yii implies efficient use of the code generator. This article shares the personalised Gii templates that were built starting from the standard templates proposed by AweGen.

When we use multiple radio buttons with same name in Yii many people have the problem on getting the value of the selected radiobutton. The radioButtonList can be used for that, but if we need to use radioButton itself to place the button any where in a view, we need to include one more parameter in htmloption array().

• First of all, You have to find out the class of the desired icon, so visit the http://getbootstrap.com/2.3.2/base-css.html#icons

There are cases that model validators should be depended by controller/action and you couldn't manipulate on the model class or using scenarios in easy way
