How to use POST data from one model in another model

Yii 1.1 General Discussion

I want to use a single search box to search all the columns in my user table and display the results in a grid. The problem is that I do not know how to get the search post data to the search() method in the user model. I know there must be a simple answer to this problem.

View code:





<div class="search-form">

<div class="wide form">


<?php $form=$this->beginWidget('CActiveForm', array(

	'action'=>Yii::app()->createUrl($this->route),

	'method'=>'get',

)); ?>

	<div class="row">

		<?php echo $form->textField($model_search,'search_string',array('size'=>60,'maxlength'=>128)); ?>

	</div>


	<div class="row buttons">

		<?php echo CHtml::submitButton('Search'); ?>

	</div>


<?php $this->endWidget(); ?>


</div>

</div><!-- search-form -->


<?php 

    // Display the user grid from user model

    $this->widget('zii.widgets.grid.CGridView', array(

    'id'=>'user-grid',

    'dataProvider'=>$model->search(),

    'columns'=>array(

        'id',

        'username',

        'email',

        array(

            'class'=>'CButtonColumn',

        ),

    ),

)); ?>

Search method in the user model. Notice the ??? where my problem is. What goes here?




public function search()

{

    // Warning: Please modify the following code to remove attributes that

    // should not be searched.


    $criteria=new CDbCriteria;


    $criteria->compare('username',<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/huh.gif' class='bbc_emoticon' alt='???' />,true, 'OR');

    $criteria->compare('email',<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/huh.gif' class='bbc_emoticon' alt='???' />,true, 'OR');




    return new CActiveDataProvider($this, array(

	'criteria'=>$criteria,

    ));

}

You should replace your ??? with the [font=“Courier New”]name[/font] attribute of the desired input field.

In your example, that would be the name of the input generated by Yii for [font="Courier New"]$model_search[/font] (is that a typo?) for the [font="Courier New"]search_string[/font] attribute.

If it’s the same model, you can just use $model->attribute syntax, like the Gii generated code.

Of course, if it’s not an attribute of your current model, you have to declare it as a public variable, and to add it as well to the safe array in your model’s validation rules.

It is not the same model because $model is type ActiveRecord, and there is no attribute for search string. I am using a separate model $model_search for the search string. Is this what you recommend, or is there another way?

What exactly do you mean by "declare it as a public variable"? Where do I declare it as a public variable?

I ended up adding a virtual attribute to the model. I think that is what bennouna was suggesting.

Yes, a virtual attribute. I’m new to MVC :slight_smile:
