What is wrong with this yii statement.? - php

Question

I have the following codes in my contoller which retrives all the data from the table...Its working fine when I use find instead of findAll... using findAll its showing error 'array to string conversion'.Is there any other way to write the query..
// Posting the full contoller Code//
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'];
$model = SearchEmployee::model()->findAll("category_id=:category AND
key_skills like :skill AND experience=:experience", array(
'category'=>$category,
'skill'=>'%'.$skills.'%',
'experience'=>$experience
));
//var_dump($model);
$this->render('search', array('model' => $model));
}
}
//view:search.php:This is my view section it is being used for searching and displaying the results //
Search Employees
<p class="note">Fields with <span class="required">*</span> are required.</p>
<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">
<?php echo $form->labelEx($model,'Skills'); ?>
<?php echo $form->textField($model,'skills'); ?>
<?php echo $form->error($model,'skills'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton('Search'); ?>
</div>
<div class="view">
<h1>Results </h1>
<div class="view" id="id">
<h4>Name : <?php echo $model ->name; ?></h4>
<h4>Skills: <?php echo $model ->key_skills; ?></h4>
<h4>Category: <?php echo $model ->category; ?></h4>
<h4>Experience: <?php echo $model ->experience; ?> Years</h4>
<h5> <?php echo CHtml::submitButton('VIew Details'); ?> </h5>
</div>
</div>
Is there any other way to write the query...Its still working as have used var_dumb to see the result.

Answer 1

It's not great to put logic like this inside your view but it may help to debug..
replace your results section with this loop in your view and see if it's where your problem lies.
<div class="view" id="id">
<?php
if(count($model)) {
foreach($model as $record) {
echo "<h4>Name : " . $record->name . "</h4>";
echo "<h4>Skills : " . $record->key_skills . "</h4>";
echo "<h4>Category : " . $record->category . "</h4>";
echo "<h4>Experience : " . $record->experience . "</h4>";
echo "<h5>" . CHtml::submitButton('VIew Details') . "</h5>";
}
}
?>
</div>

You need to learn about CGridView to display tabular information from db (or other arrays).
Based on your question, I think you should use gii tool to generate some crud files on your models. That would give you many code samples to learn from. You can activate gii by uncommenting 'gii' module in your protected/config/main.php file.
Then browse to root-of-site/index.php?r=gii
