I have 2 grids in the same module (and i need to keep them in the same module).
When i click on the top of the column the grid load itself inside itself.
Below is my code:
Myname_Blink_Adminhtml_BlinkController
public function keywordsAction()
{
$this->loadLayout();
$this->_setActiveMenu('blink/keywords');
$this->_addContent($this->getLayout()->createBlock('Myname_Blink_Block_Adminhtml_Keywords_Grid'));
$this->renderLayout();
}
my block file : Myname_Blink_Block_Adminhtml_Keywords_Grid extends
class Myname_Blink_Block_Adminhtml_Keywords_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
public function __construct()
{
parent::__construct();
$this->setId('keywords_grid');
$this->setDefaultSort('keywords_id');
$this->setDefaultDir('ASC');
//$this->setSaveParametersInSession(true);
$this->setUseAjax(true);
}
As suggested to this post: Multiple grid in Magento admin
I removed the files:
=>Myname_Blink_Block_Adminhtml_Keywords
=>app\design\adminhtml\default\default\layout\myname\blink.xml
Maybe something goes wrong with AJAX call.
Did you try this one:
http://davemacaulay.com/fix-issue-with-magento-adminhtml-grid-ajax-call-containing-the-whole-page/
public function keywordsAction()
{
if($this->getRequest()->isXmlHttpRequest()) {
$this->getResponse()->setBody($this->getLayout()->createBlock('Myname_Blink_Block_Adminhtml_Keywords_Grid')->toHtml());
return $this;
}
$this->loadLayout();
$this->renderLayout();
}
Good luck!!!

I have created a web application with Codeigniter, and I have a problem at the url, controller and structure level.
I have the following web structure.
http://projectroot/admin
Then I have several sections like:
http://projectroot/admin/users
http://projectroot/admin/profile
http://projectroot/admin/section_tracking
http://projectroot/admin/section_products
etc...
I'm working with sessions and other libraries
Currently I have everything in a single controller called Admin, but I would like to create independent controllers that would be calling each part of the url.
In Admin I have:
class Admin extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
if($this->session->userdata('login')){
if($this->session->userdata('urlnow')){
$url = $this->session->userdata('urlnow');
redirect($url);
}else{
redirect('admin/index');
}
}else{
$data = array();
$data['usererror'] = $this->session->flashdata('usererror');
$data['passerror'] = $this->session->flashdata('passerror');
$data['message'] = $this->session->flashdata('message');
$this->load->view('admin/index', $data);
}
}
...
public function users() {
code....
}
public function profile() {
code....
}
public function section_tracking() {
code....
}
public function section_products() {
code....
}
My idea is that the controller folder contains something like this:
admin.php
users.php
profile.php
section_products.php
section_visits.php
Creating independent Admin extends classes (user, profile, section_tracking and section_products) as independent controllers outside of admin, with a structure similar to this:
users.php
class Users extends Admin {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
code here...
}
}
profile.php
class Profile extends Admin {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
code here...
}
}
How can I do it? I don't want to use HMVC, I just want with MVC native.
Thank you
In your application/controllers/admin folder...Make following files
Admin.php
Users.php
Profile.php
Section_products.php
Section_visits.php
Then make call to each files like this...
http://projectroot/admin/users
http://projectroot/admin/profile
http://projectroot/admin/section_tracking
http://projectroot/admin/section_products
etc...
And here you want to extends admin controller.so make Admin_controller.php by extending CI_Controller in application/core. Your `Admin' controller must be like this....
class Admin_controller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
}
Then always extends Admin_controller.CI_Controller automatically extended.
Codeigniter gives a white screen every time a form is posted:
Here is the controller logic [controllers/account.php]:
class Account extends CI_Controller
{
public function create()
{
if($this->input->post(NULL, TRUE)){
$params = $this->input->post();
//add validation layer
$accountOptions = array($params are used here)
$this->load->model('account/account', 'account');
$this->account->initialize($accountOptions);
$this->account->save();
}
$header['title'] = "Create Free Account";
$this->load->view('front_end/header', $header);
$this->load->view('main_content');
$content['account_form'] = $this->load->view('forms/account_form', NULL, TRUE);
$this->load->view('account/create', $content);
$footer['extraJs'] = "account";
$this->load->view('front_end/footer', $footer);
}
}
Here is the Account Model logic [models/account/account.php]:
class Account extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function initialize($options)
{
//initialize
}
}
The view first loads fine then after filling the form and clicking submit, just white page.
I tried to add __construct to the controller and load account/account from there, the form does not even load. Any ideas?
I just found the problem:
- The Model account has duplicated definition and the error_reporting was off!
You shouldn't have two classes with the same name Account (the controller and model). Check your server and/or Codeigniter log it should show up there.
I advise you to call your controller class Account and your model class M_Account. You can then rename the model to account whenever you load it, just like you did:
$this->load->model('account/m_account', 'account');
public function __construct()
{
parent::__construct();
$this->load->model("account/account");
}
you load model,library and helper files in construct dont load to inside a function
I recently started using Codeigniter after having a structural problem in one of my Ajax-heavy applications. (You can read up on it if you want in my previous question)
I have a fairly short question. Currently I am making a lot of Ajax requests to different controllers. I open the controllers like this:
public function __construct()
{
parent::__construct();
$this->output->set_content_type('application/json');
}
And at the end of every function I do the following:
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
The code is pretty clear in itself, but I don't want to keep repeating myself. The codeigniter manual says to do the following:
$this->output
->set_content_type('application/json')
->set_output(json_encode(array('foo' => 'bar')));
But I would still be repeating myself. Also, I don't want to add a function to every controller that does this, even if it does decrease redundancy.
Since all of my controllers return JSON, is there a way to set this globally in a config file maybe, or in any other way?
TL;DR I have this same piece of code in every controller/function. Since the output type is always the same, just not the result, is there a way to automate this process across every controller/function?
Create an Ajax_Controller that extends MY_Controller that extends CI_Controller.
The Ajax Controller will then inherit from both Controllers.
class Ajax_Controller extends MY_Controller
{
public function __construct()
{
parent::__construct();
if(!$this->input->is_ajax_request()) return show_error('Invalid Request');
}
public function jsonOutput($json)
{
//some data checking here....
return $this->output
->set_content_type('application/json')
->set_header("HTTP/1.1 200 OK")
->set_output($json);
}
}
-
class User extends Ajax_Controller
{
public function __construct()
{
parent::__construct();
}
public function userMethod()
{
$json = json_encode(array(
'' => ''
));
$this->jsonOutput($json);
}
}
Extend your controllers from your own base class rather than CI_Controller and put your repeatedly-used function(s) and constructor code in there. Something like:
class BaseController extends CI_Controller {
protected function index() {
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
}
}
class Specific extends BaseController {
public function index() {
//do controller-specific stuff
parent::index();
}
}
I abstract this further if I have groups of controllers with shared code; for example, if I had a bunch of controllers that require the user to be logged-in I create AuthenticatedController, which extends BaseController and add session checks etc.
I am calling my block from controller but it doesn't display header buttons.I call my controller function with button click and create block using (
$this->loadLayout();
$this->_addContent($this->getLayout()->createBlock('mymodule/adminhtml_mymodule_edit_tab_addanswer'));
$this->renderLayout();.
While on addanswer page i simply use the class
Mymodule_Block_Adminhtml_module_Edit_Tab_Addanswer extends Mage_Adminhtml_Block_Widget_Form
{
protected function _prepareForm()
{
// code
}
}
It display data like the attach image
I want to add save or add like buttons but don't know from where i can do that.I added buttons from block or from edit.php but i don't know how i can add buttons from controller or in form direct.Is it possible ? Thanks in advance
You maybe missing
class CompanyName_Mymodule_Block_Adminhtml_Addanswer_Edit extends Mage_Adminhtml_Block_Widget_Form_Container
{
public function __construct()
{
parent::__construct();
$this->_objectId = 'id';
$this->_blockGroup = 'addanswer';
$this->_controller = 'adminhtml_addanswer';
$this->_updateButton('save', 'label', Mage::helper('addanswer')->__('Save'));
$this->_updateButton('delete', 'label', Mage::helper('addanswer')->__('Delete'));
}

Take a look # Custom Module with Custom Database Table
i'm using codeigniter for my project and i have this class model which i call Genesis which looks like this:
class Genesis_model extends CI_Model {
function __construct() {
parent::__construct();
}
function get() {
return 'human soul';
}
}
and i have another model, stored in the same directory, which extends Genesis_model
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return $this->get();
}
}
Human_model is used by Human controller
class Human extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->model('human_model');
}
function get_human() {
$data['human'] = $this->human_model->get_human();
$this->load->view('human/human_interface', $data);
}
}
if i execute the code, it will produce an error which point to return $this->get(). it reads "Fatal error: Class 'Genesis_model' not found in ...\application\models\human_model.php on line 2".
i use this method because nearly all my models shared almost identical structure. I gather the similar functionality in Genesis while the other models serve only as data suppliers unique to the tables they represent. it works well in my asp.net (vb.net) but i don't how to do it in codeigniter.
is there a way for Human_model to inherit Genesis_model. i don't think i'm allowed to use include('genesis_model.php'). i don't know if it works either.
thanks in advance.
core/MY_Model is good if there's only 1 important superclass for your models.
If you want to inherit from more than model superclass, a better option is to change your autoload configuration.
In application/config/autoload.php, add this line:
$autoload['model'] = array('genesis_model');
Put the file genesis_model.php in the core directory
Change your Human_model to this:
include('genesis_model.php');
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return parent::get();
}
}
notice the get_human function and the include.
You have to include the Genesis_model on your Human_model.php like this:
include_once( APPPATH . 'folder/file' . EXT );
Or you can autoload it on your config/autoload.php file, what I think is stupid =)
other solution
<?php
$obj = &get_instance();
$obj->load->model('parentModel');
class childModel extends parentModel{
public function __construct(){
parent::__construct();
}
public function get(){
return 'child';
}
}
?>
