I'm developing a Joomla component where I have a treeview in the sidebar with the content of a database table. When clicking a node of this sidebar I want to show the children nodes in the main part of the window as a list (as the windows explorer does). For what I have been reading the best way to do this is an ajax request like explained here.

I link to the url in each node: href="index.php?option=com_nautilus&task=datalist&format=raw"

In controller.php I add:

Blockquote

public function datalist() { $this->input->set('view', 'Datalist'); parent::display(); }

I create /views/datalist with the file view.raw.php

Blockquote

<?php defined('_JEXEC') or die; jimport('joomla.application.component.view'); class SimilarViewDatalist extends JViewLegacy { function display($tpl = null) { parent::display($tpl); } }

and /views/datalist/tmpl with the file default.php

Blockquote

 <?php echo "Hello World from /views/datalist/tmpl/default.php";

But I get:

An error has occurred. 500 View class not found [class, file]: nautilusViewDatalist, C:\xampp\apps\joomla\htdocs\administrator\components\com_nautilus\views\dataList\view.raw.php

Reset to default

Your component's name is com_nautilus. With Joomla MVC your controller is looking for a class called "nautilusViewDatalist" in the file view.raw.php but you named your class "SimilarViewDatalist". That's were the error 500 comes from.

How to Implement Ajax in Joomla Component

Create Controller File Where you will send ajax request from javascript to PHP

controller.php

<?php defined('_JEXEC') or die('Access Deny'); jimport('joomla.application.component.controller'); class OpenChatController extends JController { function saveChatViaAjax() { $app=JFactory::getApplication(); $jinput=$app->input; $res=array(); //Implement Your Logic i am giving some sample response $res['status']=true; $res['msg']=$jinput->get('msg'); echo json_encode($res); $app->close(); } }

From View Page You will send Ajax request using Jquery(also you can use native javascript xhr)

<script> $(document).ready(function() { //Sending Ajax Request to saveChatViaAjax method on Controller OpenChatController var param={}; param.option='com_openchat'; param.task='saveChatViaAjax'; param.msg='Please save this mesage'; $.post('index.php',param,function(res){ console.log(res); }); }); </script>
