    <p>I am a Yii Beginner and I am currently working on a Tagging system where I have 3 tables:</p> <ul> <li><p>Issue (id,content,create_d,...etc)</p></li> <li><p>Tag (id,tag)</p></li> <li><p>Issue_tag_map (id,tag_id_fk,issue_id_fk)</p></li> </ul> <p>In my <code>/Views/Issue/_form</code> I have added a <a href="http://www.yiiframework.com/extension/multicomplete/" rel="nofollow">MultiComplete</a> Extension to retrieve multiple tag ids and labels,</p> <p>I have used an <code>afterSave</code> function in order to directly store the <code>Issue_id</code> and the autocompleted <code>Tag_id</code>s in the <code>Issue_tag_map</code> table, where it is a <code>HAS_MANY</code> relation.</p> <p>Unfortunately Nothing is being returned.</p> <p>I wondered if there might be a way to store the autocompleted Tag_ids in a temporary attribute and then pass it to the model's <code>afterSave(</code>) function.</p> <p>I have been searching for a while, and this has been driving me crazy because I feel I have missed a very simple step! </p> <p>Any Help or advices of any kind are deeply appreciated!</p> <p><em>MultiComplete in <code>Views/Issue/_form</code></em>:</p> <pre><code> &lt;?php echo $form-&gt;labelEx($model, 'Tag'); $this-&gt;widget('application.extension.MultiComplete', array( 'model' =&gt; $model, 'attribute' =&gt; '', //Was thinking of creating a temporary here 'name' =&gt; 'tag_autocomplete', 'splitter' =&gt; ',', 'sourceUrl' =&gt; $this-&gt;createUrl('Issue/tagAutoComplete'), // Controller/Action path for action we created in step 4. // additional javascript options for the autocomplete plugin 'options' =&gt; array( 'minLength' =&gt; '2', ), 'htmlOptions' =&gt; array( 'style' =&gt; 'height:20px;', ), )); echo $form-&gt;error($model, 'issue_comment_id_fk'); ?&gt; </code></pre> <p><em>AfterSave in <code>/model/Issue</code></em>:</p> <pre><code> protected function afterSave() { parent::afterSave(); $issue_id = Yii::app()-&gt;db-&gt;getLastInsertID(); $tag; //here I would explode the attribute retrieved by the view form // an SQL with two placeholders ":issue_id" and ":tag_id" if (is_array($tag)) foreach ($tag as $tag_id) { $sql = "INSERT INTO issue_tag_map (issue_id_fk, tag_id_fk)VALUES(:issue_id,:tag_id)"; $command = Yii::app()-&gt;db-&gt;createCommand($sql); // replace the placeholder ":issue_id" with the actual issue value $command-&gt;bindValue(":issue_id", $issue_id, PDO::PARAM_STR); // replace the placeholder ":tag_id" with the actual tag_id value $command-&gt;bindValue(":tag_id", $tag_id, PDO::PARAM_STR); $command-&gt;execute(); } } </code></pre> <p>And this is the Auto Complete sourceUrl in the Issue model for populating the tags:</p> <pre><code> public static function tagAutoComplete($name = '') { $sql = 'SELECT id ,tag AS label FROM tag WHERE tag LIKE :tag'; $name = $name . '%'; return Yii::app()-&gt;db-&gt;createCommand($sql)-&gt;queryAll(true, array(':tag' =&gt; $name)); </code></pre> <p>actionTagAutoComplete in /controllers/IssueController:</p> <pre><code>// This function will echo a JSON object // of this format: // [{id:id, name: 'name'}] function actionTagAutocomplete() { $term = trim($_GET['term']); if ($term != '') { $tags = issue::tagAutoComplete($term); echo CJSON::encode($tags); Yii::app()-&gt;end(); } } </code></pre> <p><strong>EDIT</strong></p> <p>Widget in form:</p> <pre><code> &lt;div class="row" id="checks" &gt; &lt;?php echo $form-&gt;labelEx($model, 'company',array('title'=&gt;'File Company Distrubution; Companies can be edited by Admins')); ?&gt; &lt;?php $this-&gt;widget('application.extension.MultiComplete', array( 'model' =&gt; $model, 'attribute' =&gt; 'company', 'splitter' =&gt; ',', 'name' =&gt; 'company_autocomplete', 'sourceUrl' =&gt; $this-&gt;createUrl('becomEn/CompanyAutocomplete'), 'options' =&gt; array( 'minLength' =&gt; '1', ), 'htmlOptions' =&gt; array( 'style' =&gt; 'height:20px;', 'size' =&gt; '45', ), )); echo $form-&gt;error($model, 'company'); ?&gt; &lt;/div&gt; </code></pre> <p>Update function:</p> <pre><code> $model = $this-&gt;loadModel($id); ..... if (isset($_POST['News'])) { $model-&gt;attributes = $_POST['News']; $model-&gt;companies = $this-&gt;getRecordsFromAutocompleteString($_POST['News'] ['company']); ...... ...... getRecordsFromAutocompleteString(): public static cordsFromAutocompleteString($string) { $string = trim($string); $stringArray = explode(", ", $string); $stringArray[count($stringArray) - 1] = str_replace(",", "", $stringArray[count($stringArray) - 1]); $criteria = new CDbCriteria(); $criteria-&gt;select = 'id'; $criteria-&gt;condition = 'company =:company'; $companies = array(); foreach ($stringArray as $company) { $criteria-&gt;params = array(':company' =&gt; $company); $companies[] = Company::model()-&gt;find($criteria); } return $companies; } </code></pre> <p><strong>UPDATE</strong> since the "value" porperty is not implemented properly in this extension I referred to extending this function to the model:</p> <pre><code> public function afterFind() { //tag is the attribute used in form $this-&gt;tag = $this-&gt;getAllTagNames(); parent::afterFind(); } </code></pre>

    1. COJust 2 little questions before answering: the autocomplete is working, right? Did you define the relations between Issue and Tag in your models? (I need those informations to make my answer more accurate)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
