How to create the autocomplete profile question in SocialEngine?

You probably know that most websites should have “friendly search.” A search which can find the results by typing in the text field and results will papulate on the screen. Autocomplete, also called “type-ahead search”, can enhance the search experience by finding potential terms in the index that match the partial term being written by the user but we are stuck on SocialEngine to meet this feature, one of our client ScienceJnr need this features that’s why we are think about this feature. So we are implementing this feature on SocialEngine.

Than We have decided to add a form element in the form but later on, we realize that whenever we add a new profile type we need a developer to customize the solution which is not a good approach. We want a dynamic solution like First Name or Gender(that already exist) field in SocialEngine. So the problem is how we create this type of element so that it can be added dynamically as a question of the different profile type. To find the best solution we have uses the following approach this might helps others.


Step1. Register a new form element: First, we need to register our new element with SocialEngine. Add the following code inside the application/modules/Fields/settings/fields.php

 'jobposition' => array(
        'base' => 'text',
        'label' => 'Job Position',
        'category' => 'specific',

Step2. Create your form element: Now create your element, Navigate to the application/modules/Fields/Form/Element and create a file Jobposition.php. Here my element name is ‘jobposition’. In the following code, we are creating a autocomplete field element which derived from Text element type.

class Fields_Form_Element_Jobposition extends Engine_Form_Element_Text{
    public function init()
        $this->setAttrib('module', 'sciencejnr');
        $this->setAttrib('controller', 'article');
        $this->setAttrib('action', 'jobposition');

    public function loadDefaultDecorators()
        if( $this->loadDefaultDecoratorsIsDisabled() )

        $decorators = $this->getDecorators();
        if( empty($decorators) )

Step3. Create a decorator: Now we have to create a decorator class to render the new element in the form. Navigate to the application/libraries/Engine/Form/Decorator and create a file jobPostionWrapper.php and add the following code.

class  Engine_Form_Decorator_JobPositionWrapper extends Zend_Form_Decorator_Abstract
     * Default placement: surround content
     * @var string
    protected $_placement = null;

     * Render
     * Renders as the following:
     * @param  string $content
     * @return string
    public function render($content)
        $elementName = $this->getElement()->getName();

        $url = $this->getElement()->getAttrib('url');
        $module = $this->getElement()->getAttrib('module');
        $controller = $this->getElement()->getAttrib('controller');
        $action = $this->getElement()->getAttrib('action');
        if( $url ) {
            $this->getElement()->setAttrib('url', null);

        if( $module ) {
            $this->getElement()->setAttrib('module', null);
        if( $controller ) {
            $this->getElement()->setAttrib('controller', null);
        if( $action ) {
            $this->getElement()->setAttrib('action', null);
        $view = $this->getElement()->getView();
        return $view->partial('suggest/suggest.tpl', 'fields', array(
            'name' => $elementName,
            'url' => $url,
            'element' => $this->getElement(),
            'module' => $module,
            'controller' => $controller,
            'action' =>$action


Step4. Create a tpl file to add an HTML and javascript static code:  Here is the example of html code. Navigate to the application/modules/Fields/views/scripts/suggest and create a file suggest.tpl and add the following to the tpl file:

    ->appendFile($this->layout()->staticBaseUrl . 'application/modules/Seaocore/externals/scripts/autocompleter/Autocompleter.js');
$elementName = $this->name;
$module = $this->module;
$ctl = $this->controller;
$action = $this->action;
$element = $this->element;
$name = explode('_', $elementName);



        new Autocompleter.Request.JSON(element, '', {
            'minLength': 1,
            'delay' : 250,
            'selectMode': 'pick',
            'autocompleteType': 'message',
            'multiple': false,
            'className': 'message-autosuggest',
            'filterSubset' : true,
            'tokenFormat' : 'object',
            'tokenValueKey' : 'label',
            'elementValues': 'toValues',
            'injectChoice': function(token){
                var choice = new Element('li', {
                    'class': 'autocompleter-choices friendlist',
                new Element('div', {
                    'html': this.markQueryValue(token.label),
                    'class': 'autocompleter-choice'
      'autocompleteChoice', token);
            , onPush : function(){
                $('').setStyle('display', 'none');
                //$('-toVales-wrapper').setStyle('display', 'block');
                $('').disabled = true;
    function removeFromToValue(id,id2,id3,id4) {
        // code to change the values in the hidden field to have updated values
        // when recipients are removed.
        var toValues = $(id4).value;
        var toValueArray = toValues.split(",");
        var toValueIndex = "";
        var checkMulti =,/);

        // check if we are removing multiple recipients
        if (checkMulti!=-1){
            var recipientsArray = id.split(",");
            for (var i = 0; i < recipientsArray.length; i++){
                removeToValue(recipientsArray[i], toValueArray, id3);
            removeToValue(id, toValueArray, id3);

        // hide the wrapper for usernames if it is empty
        if ($(id3).value==""){
            $(id4+'-wrapper').setStyle('height', '0');

        $(id3).disabled = false;
        $(id3).setStyle('display', 'block');
       // $(id4+'-wrapper').setStyle('display', 'none')
    function removeToValue(id, toValueArray, id4){
        for (var i = 0; i < toValueArray.length; i++){
            if (toValueArray[i]==id) toValueIndex =i;
        toValueArray.splice(toValueIndex, 1);
        $(id4).value = toValueArray.join();

Step5. Now add this new element type as profile question: To add question to the profie type use the default approach of SocialEngine. Selectt the job posiotn while selecting the question type as shown in the image:
And in the form this will show you like this:



This article explains creating a autocomplete form element in SocialEngine so that we can create SocialEngine autocomplete profile question for the profile types. Autocomplete is the most used form elements nowadays due to less input error. It suggests the user enter a valid data. If any better approach or solution your thought are most welcome.
