i have created one news module . it is working fine..
http://domain.com/magento/news
this page is displaying all the news items. with title, content and date.
i want to make view more link for content when user click on view more link it will redirect user to specific newsitem page
http://domain.com/magento/news/newsitem-1
i created another controller newsitemController.php with following code :
public function infoAction(){
$this->loadLayout();
$this->getLayout()->getBlock('content')
->append($this->getLayout()->createBlock('news/newsitem') );
$this->renderLayout();
}
also created block name info.php with below code:
public function _prepareLayout()
{
return parent::_prepareLayout();
}
public function getnewsitem()
{
if(!$this->hasData('news')) {
$this->setData('news', Mage::registry('news'));
}
return $this->getData('news');
}
not getting output..
need help to get output.
In your info.php add the following function to get the url of the news item.
public function getItemUrl($newsItem)
{
return $this->getUrl('*/*/view', array('id' => $newsItem->getId()));
}
In your controller add following function to view the news detail page.
public function viewAction()
{
$model = Mage::getModel('magentostudy_news/news');
$model->load($newsId);
$this->loadLayout();
$itemBlock = $this->getLayout()->getBlock('news.info');
$this->renderLayout();
}
By doing this you can simply access the info page attaching this link on read more like
foreach ($this->getCollection() as $newsItem)
{

I was able to incorporate elasticsearch on cakephp 3 but I lost the ability to save on my database. The add method on the controller creates an index instead of doing both (save to table and create an index in elasticsearch). Followed the instructions from here - https://book.cakephp.org/3.0/en/elasticsearch.html.
Any idea on how I can achieve the above?
Thanks.

How to access Model from Views in Codeigniter.
I have a Model with a function, i need to call this function from view
Please Read the CI documentation First:
If You are using a MVC Structured Framework then you should be following the way it works.
You Need the Controller:
public function your_controller_function(){
// To load model
$this->load->model ('your_model');
//To Call model function form controller
$data = $this->your_model->model_function($ex_data);
//TO Send data to view
$this->load->view('your_view',['data'=>$data]);
}
Inside your model:
public function model_function($ex_data){
// Your Querys
// user return to send you query result to the controller anything
// Sample Example of query and return
$query = $this->db->select('*')
->where('your_column',$data['column_name'])
->get('your_table');
$your_result = $query->row_array();
if($this->db->affected_rows() > 0){
return your_result;
} else {
return FALSE;
}
}
Inside your view you can write :
<?php
$this->load->model('your_model');
$this->your_model->some_function();
?>
For example in User_controller load User Model $this->load->model('Users_model');
Then User View page $viewpage = this->Users_model->somefunction($id);
I'm new to cakePHP. Needless to say I don't know where to start reading. Read several pages about AJAX and JSON responses and all I could understand is that somehow I need to use Router::parseExtensions() and RequestHandlerComponent, but none had a sample code I could read.
What I need is to call function MyController::listAll() and return a Model::find('all') in JSON format so I can use it with JS.
Do I need a View for this?
In what folder should that view go?
What extension should it have?
Where do I put the Router::parseExtension() and RequestHandlerComponent?
// Controller
public function listAll() {
$myModel = $this->MyModel->find('all');
if($this->request->is('ajax') {
$this->layout=null;
// What else?
}
}
I don't know what you read but I guess it was not the official documentation. The official documentation contains examples how to do it.
class PostsController extends AppController {
public $components = array('RequestHandler');
public function index() {
// some code that created $posts and $comments
$this->set(compact('posts', 'comments'));
$this->set('_serialize', array('posts', 'comments'));
}
}
If the action is called with the .json extension you get json back, if its called with .xml you'll get xml back.
If you want or need to you can still create view files. Its as well explained on that page.
// Controller code
class PostsController extends AppController {
public function index() {
$this->set(compact('posts', 'comments'));
}
}
// View code - app/View/Posts/json/index.ctp
foreach ($posts as &$post) {
unset($post['Post']['generated_html']);
}
echo json_encode(compact('posts', 'comments'));
// Controller
public function listAll() {
$myModel = $this->MyModel->find('all');
if($this->request->is('ajax') {
$this->layout=null;
// What else?
echo json_encode($myModel);
exit;
// What else?
}
}
You must use exit after the echo and you are already using layout null so that is OK.
You do not have to use View for this, and it is your wish to work with components. Well all you can do from controller itself and there is nothing wrong with it!

In Cakephp 3.5 you can send json response as below:
//in the controller
public function XYZ() {
$this->viewBuilder()->setlayout(null);
$this->autoRender = false;
$taskData = $this->_getTaskData();
$data = $this->XYZ->getAllEventsById( $taskData['tenderId']);
$this->response->type('json');
$this->response->body(json_encode($data));
return $this->response;
}
Try this:
public function listAll(){
$this->autoRender=false;
$output = $this->MyModel->find('all')->toArray();
$this->response = $this->response->withType('json');
$json = json_encode($output);
$this->response = $this->response->withStringBody($json);
}
Im new to codeigniter and im developing my first web application with it and want to make sure im doing best practices the 1st time so i dont have to go back to make corrections down the road. with that said, here is what im doing.
I want to edit a note in the DB, then after the record has been updated redirect to a different page.
my model is coded correctly so im not worried there, but the controller looks like this (and this is probably not correct:
public function edit($id) {
$this->load->model('Notes_model');
if (isset($_POST["edit"]))
{
$data['data'] = $this->Notes_model->edit($id);
$url = "/Notes/view/" . $id;
redirect($url);
}
$data['notes'] = $this->Notes_model->viewNotes($id);
$this->load->view('templates/header');
$this->load->view('notes/edit', $data);
$this->load->view('templates/footer');
}
hopefull this makes sense, basically what I'm wanting to do here is:
1.) Show the edit note page
2.) if i edited that page by hitting submit
a.) update the db
b.) redirect to a different page.
does this look pretty good or should i make some better changes?
Although your controller code is fine but one thing you have to take care that you should load model in the constructor of your controller so you don't have to include the model in each function same recommendations for the libraries, helpers this is the best practice
class myclass extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('Notes_model');
$this->load->helper(form);
}
public function myfunction(){
}
}
Here is the starting tutorial with MVC standards advanced-codeigniter-techniques-and-tricks
<?php
class Home extends CI_Controller
{
function __construct() {
parent::__construct();
$this->m_auth->notLogin();
$this->load->library('form_validation');
$this->load->library('ajax_pagination');
$this->load->library('dateconverter');
$this->load->helper('template');
$this->load->helper('check');
$this->load->model('mymodels/crud_model');
$this->lang->load('personal', $this->m_auth->get_language());
$this->lang->load('global', $this->m_auth->get_language());
}
function index()
{
$this->get_recs();
}
function get_recs()
{
//get for view or first page to be showed
}
/**
* Register New User
*/
function updateRecords()
{
$this->form_validation->set_rules('ministery','<span class="req">(Ministry)</span>','trim|required');
$this->form_validation->set_rules('directorate','<span class="req">(Directorate)</span>','trim|required');
if($this->form_validation->run()==FALSE)
{
header_tpl($this->m_auth->get_language(),'a');
banner_tpl($this->m_auth->get_language(),'a');
left_tpl($this->m_auth->get_language(),'a');
$content = $this->load->view('personal/edit_personal', $this->POST,true);
content_tpl($content);
footer_tpl();
}
else
{
$form_data = array(
'ministry' => $this->input->post('ministery'),
'directorate' => $this->input->post('directorate'),
'job_province' => $this->input->post('job_province'),
'job_district' => $this->input->post('job_district'),

);
if($this->crud_model->update_recs('ast_emp_property',$form_data)==TRUE)
{
$this->session->set_flashdata("msg","<span class='m_success'>".$this->lang->line('global_insert_success')."</span>");
redirect('/home/success_reg/'.$id.'','refresh');
}
