undefined variable model in yii

Question

I am getting the error undefined variable model. I have the following codes in my view and controller. My aim is to search the results and show it in same page. I have tried the following things but its not working.

Again,I this this the conventional yii method to do so,or do I have to use a search() function from model SearchEmployee().?

public function actionSearch()
{
      $model = new SearchEmployee();

       /*Getting Data From Search Form For Processing */
  if (isset($_POST['SearchEmployee'])) {

      $category   =  $_POST['SearchEmployee']['category_id'];
      $skills     =  $_POST['SearchEmployee']['skills'];
      $experience =  $_POST['SearchEmployee']['experience'];

      $model = SearchEmployee::model()->find(array(
      'select' => array('*'), "condition" => "category_id=$category AND key_skills like '%$skills%' AND experience=$experience",
      ));

      $this->render('search',$model);
  }

  /*Getting Data From Search Form For Processing */
  $this->render('search', array('model' => $model));
}

In View Section: search.php//To display and search the desired result

<div class="row">
   <?php echo $form->labelEx($model,'Category'); ?>
   <?php echo $form->dropDownList($model,'category_id',$list,array('empty' =>'(Select a Category')); ?>
   <?php echo $form->error($model,'category'); ?>
</div>

  <div class="row">
<?php echo $form->labelEx($model,'Experience'); ?>
    <?php echo $form->textField($model,'experience'); ?>
    <?php echo $form->error($model,'experience'); ?>    
</div>


<div class="row buttons">
  <?php echo CHtml::submitButton('Search'); ?>
</div>



<div class="view">

  <h1>Results </h1>

  <div class="view" id="id">

     <h1> Records Display </h1>

     <h4>Name:        <?php echo $form->labelEx($model,'name'); ?></h4>
     <h4>Skills:      <?php echo $form->labelEx($model,'experience'); ?></h4>
     <h4>Experience:  <?php echo $form->labelEx($model,'skills'); ?></h4>
     <h5>&nbsp;&nbsp ;<?php echo $form->labelEx('VIew Details'); ?></h5>
   </div>

 </div>

In view section I am using the search and view results option in the same form.I am getting the error after clicking the search button.Is this the correct way to do

The error usually shows a line number and a trace as well. Do you have that? — Nathan H

Nathan...its here in view page search.php '<?php echo $form->labelEx($model,'Category'); ?>' — saji

By the way your "find" query looks very unsafe, if not invalid. You should study the correct way to use ActiveRecords — Nathan H

Your search.php shows a submit button but not "form" - are you sure everything is here? — Nathan H

$model = SearchEmployee::model()->find(array(
                  'select' => array('*'), "condition" => "category_id=$category AND
         key_skills like '%$skills%' AND experience=$experience",
));

There is error here. You can't use find in that way.

public function find($condition='',$params=array())

$model = SearchEmployee::model()->find("category_id=$category AND
         key_skills like '%$skills%' AND experience=$experience");

But better

$model = SearchEmployee::model()->find("category_id=:category AND key_skills like :skill AND experience=:experience", array(
    'category'=>$category,
    'skill'=>'%'.$skills.'%',
    'experience'=>$experience
));

I would recommend new CDbCriteria - especially when you explain it to a new Yii user.

Remove this line:

$this->render('search',$model);

First it's invalid because it should be:

$this->render('search', array('model' => $model));

But also it's unnecessary because you already have it lower in your code.
