[EXTENSION] My first try: Add a "search" field to the Blog-Demo

Yii 1.1 Extensions
1

Hello everyone,

i am still a Yii-Beginner and i was trying to write an small search-portlet as an extension to the blog-demo.

At first, i added a SiteSearchPortlet.php to protected/components :

protected/components/SiteSearchPortlet.php:



<?php





class SiteSearchPortlet extends Portlet {


    


    public function renderContent() {


                $form = new SiteSearchForm();


                $this->render('siteSearch',array('form'=>$form));


    }


}


 ?>

Then i added a small view for this Portlet:

protected/components/views/siteSearch.php :



<?php echo CHtml::beginForm(); ?>


<div class="row">


<?php echo CHtml::activeTextField($form,'search_string') ?>


<?php echo CHtml::error($form,'search_string'); ?>


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


</div>


<?php echo CHtml::endForm(); ?>

At last, i wanted to set up the Model Logic:

protected/models/SiteSearchForm.php :



<?php





class SiteSearchForm extends CFormModel


{


        public $search_string;





        public function rules() {


                return array( array('searchstring', 'required'),);


        }





        public function actionSearch() {


                $condition = new CdbCriteria;


                $params = array();


                $posts=Post::model()->findAll($condition,$params);


          print_r($posts); // Stuck here





} 





}

Now i have some trouble to understand, how Yii determines, which function is called, after the Submit-Button is pushed. After that, i just want to display these posts, that have ‘content like “%search_string%”’ as a CdbCriteria. Could some of you Yii-Experts give me an hint ;)

You'd better write an actionSearch in the appropriate controller, which in this case can be the PostController.

May be you do not wanna see, here is an example implementation.

Ah, ok! Thanks a lot. I really did not find this great extended blog demo Example.

It works now, but i needed to adjust the views/post/list.php a little bit:



<?php if(!empty($_POST['SiteSearchForm'])) { ?>





<h3>Posts that contain "<?php





$temparray = $_POST['SiteSearchForm'];


$searchstring = $temparray['search_string'];





echo CHtml::encode($searchstring); ?>":</h3>





<ul>


<?php


  foreach($posts as $post) {


    echo "<li><b>" . CHtml::link($post->title,array('show','id'=>$post->id)) ."</b> <br> $post->preview</li>";


  }


?>


</ul>


</div>


<?php


} else {





foreach($posts as $post) {


  $this->renderPartial('_post',array( 'post'=>$post,));


}


echo "<br/>";


$this->widget('CLinkPager',array('pages'=>$pages)); } ?>

Oh, it seems like the Formvalidator does not work. I can click "search" without entering anything?

Did the author of the extended blog demo forget about that, or is something broken with my installation??
