I have a plugin: Simple Configurable Products. I've upgraded to 1.8.1 but have an issue with showing the price - it stops rendering the page.
I have found the line that's causing the issue:
parent::_toHtml();
The class that is calling that is as follows:
class OrganicInternet_SimpleConfigurableProducts_Catalog_Block_Product_Price
extends Mage_Catalog_Block_Product_Price
{
public function _toHtml() {
// Do some stuff
return parent::_toHtml();
}
}
So as I see it, the parent class should be: Mage_Catalog_Block_Product_Price. And the line that calls this should simply call the function _toHtml(). Taking this line out means it works, but returns no price. Ideally I need it to render the default/base price html.
Thanks in advance
Try calling it like this:
class OrganicInternet_SimpleConfigurableProducts_Catalog_Block_Product_Price
extends Mage_Catalog_Block_Product_Price {
public function _toHtml() {
// Do some stuff
return Mage_Catalog_Block_Product_Price::_toHtml();
}
}
Call the object by name instead of by parent::_toHtml()

I am working on Magento 2. I want to use other module's block function to get some data. How can I call that block function in my module's model file ?
The two ways to call you a block class method in custom module class
1) using constructor dependency
like that
public function __construct(Namespace\ModuleName\Helper\Data $helper)
{
$this->helper = $helper;
}
public function MyFunction()
{ $this->helper->HelperDemo();
}
2) using method dependency
public function execute(Namespace\ModuleName\Helper\Data $helper)
{
$helper->HelperDemo();
}

I'm attempting to customize the way pricing / tiered pricing is displayed in Magento CE 1.6.0.0.
I've followed the instructions in the second post of the link below to override Mage_Catalog_Model_Product_Type_Price
http://www.magentocommerce.com/boards/viewthread/16829/
Following is my custom model class:
class PHC_Price_Model_Price extends Mage_Catalog_Model_Product_Type_Price {
public function getPrice() {
echo "overridden getPrice method called<br>";
}
public function getPHCDisplayPrice($product) {
echo "custom price function called<br>";
}
}
I'm able to successfully call the overridden getPrice() function from my template file as follows:
$product = Mage::getModel("catalog/product")->load($_product->entity_id);
$displayPrice = $product->getPrice();
However, when I try to call my custom price function with
$product = Mage::getModel("catalog/product")->load($_product->entity_id);
$displayPrice = $product->getPHCDisplayPrice();
I get absolutely nothing. Can anyone tell me what I'm missing?
It't normal that you don't get a result. I would be amazed if this worked.
You are overriding the class Mage_Catalog_Model_Product_Type_Price, but in your example the $product variable is an instance of Mage_Catalog_Model_Product. That class does not have the method getPHCDisplayPrice and it calls the __call method and returns null.
You get the expected result when calling getPrice by accident. It is because the getPrice method in Mage_Catalog_Model_Product looks like this:
public function getPrice()
{
if ($this->_calculatePrice || !$this->getData('price')) {
return $this->getPriceModel()->getPrice($this);
} else {
return $this->getData('price');
}
}
So when you call it, it calls $this->getPriceModel()->getPrice($this) and $this->getPriceModel() returns an instance of your class.
I have a Joomla helper class that I'm using for module development with a method I'm trying to call:
class modCamcloudReferralHelper
{
/*
* Sanitize email form
*/
public function isInjected($str) {
$inject = "/(\r|\t|%0A|%0D|%08|%09)+/i";
return (preg_match($inject, $str) > 0);
}
public static function sendEmail() {
$jinput = JFactory::getApplication()->input;
$email = $jinput->post->get('email', '', 'STRING');
//check email is fine
if (isInjected($email)){ //never get into this code and it causes some sort of failure
echo "blah";
}
}
}
Simple, right? But this code just gives me a blank page and I don't see any errors...anywhere. I can instead just put this code right into my sendEmail function and it works just fine:
$inject = "/(\r|\t|%0A|%0D|%08|%09)+/i";
if (preg_match($inject, $email) > 0){
echo "This works";
}
I've had this problem with my Joomla components I've built before. For some reason calling this function from inside the same class is not working. It must be a Joomla thing...or I'm going nuts. Any ideas?
You should call the method with a reference to its container, even if it's local.
So the right syntax here is:
if (self::isInjected($email))
of from another class:
modCamcloudReferralHelper::isInjected(
This is good for helpers: just make sure you declare the method you are invoking as static
public static function isInjected($str) {
If however you're calling a method on an instantiated class (a view, a template, a model, you should use
$this->method()
i have a controller having following script
class get extends CI_Controller
{
function get_password()
{
$this->load->model('fetch_model');
$user_pass=$this->fetch_model->get_password();
$data['user_pass'] = json_encode($user_pass);
echo $data['user_pass'];
}
}
and a script on view page as this
function get_password(){
$.post("<?php echo base_url();?>admin.php/get/get_password",function(data)
{
for(i=0;i<data.length;i++)
{
$('#password').val(data[i].password);
$('#username').val(data[i].username);
}
},"json");
}
now if i use the following script in model then the ajax post is working perfectly..
class fetch_model extends CI_Model
{
function get_password()
{
return $this->db->query("SELECT * FROM td_admin_user")->result_array();
}
}
but when i change the model script into this, then the ajax script isnt working
class fetch_model extends CI_Model
{
function get_password()
{
foreach($this->db->query("SELECT * FROM td_admin_user")->result() as $r_pass)
{
$pass=$r_pass->password;
$user=$r_pass->username;
}
$user_pass=array('username'=>$user,
'password'=>$pass);
return $user_pass;
}
}
but to be very frankly, i need to send data in the following way
$user_pass = array('username'=>$user, 'password'=>$pass);
and not as result_array()
so please help me in this context, thanks in advance
This is not a bug! Did you even look at what type of data is returned in each call?
In your JS, you are using:
$('#password').val(data[i].password);
Where data is an indexed array - exactly what is returned by ->result_array()
But you want it to be a key based array:
$user_pass=array('username'=>$user, 'password'=>$pass);
If that's the case, you should forget using the for loop on JS (specially if your query only results in one row) and use
$('#password').val(data.password);
Instead.
Also look at console.log (if you are using firebug/developer tools) and try print_r or var_dump on the PHP side to understand the data formats you are returning.
I have two controllers a and b.
I would like to call a method of controller a from a method of controller b.
Could anyone help explain how I can achieve this?
This is not supported behavior of the MVC System. If you want to execute an action of another controller you just redirect the user to the page you want (i.e. the controller function that consumes the url).
If you want common functionality, you should build a library to be used in the two different controllers.
I can only assume you want to build up your site a bit modular. (I.e. re-use the output of one controller method in other controller methods.) There's some plugins / extensions for CI that help you build like that. However, the simplest way is to use a library to build up common "controls" (i.e. load the model, render the view into a string). Then you can return that string and pass it along to the other controller's view.
You can load into a string by adding true at the end of the view call:
$string_view = $this->load->view('someview', array('data'=>'stuff'), true);
test.php Controller File :
Class Test {
function demo() {
echo "Hello";
}
}
test1.php Controller File :
Class Test1 {
function demo2() {
require('test.php');
$test = new Test();
$test->demo();
}
}
Very simple way in codeigniter to call a method of one controller to other controller
1. Controller A
class A extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_a()
{
}
}
2. Controller B
class B extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_b()
{
require_once(APPPATH.'controllers/a.php'); //include controller
$aObj = new a(); //create object
$aObj->custom_a(); //call function
}
}
I agree that the way to do is to redirect to the new controller in usual cases.
I came across a use case where I needed to display the same page to 2 different kind of users (backend user previewing the page of a frontend user) so in my opinion what I needed was genuinely to call the frontend controller from the backend controller.
I solved the problem by making the frontend method static and wrapping it in another method.
Hope it helps!
//==========
// Frontend
//==========
function profile()
{
//Access check
//Get profile id
$id = get_user_id();
return self::_profile($id);
}
static function _profile($id)
{
$CI = &get_instance();
//Prepare page
//Load view
}
//==========
// Backend
//==========
function preview_profile($id)
{
$this->load->file('controllers/frontend.php', false);
Frontend::_profile($id);
}
I posted a somewhat similar question a while back, but regarding a model on CI.
Returning two separate query results within a model function
Although your question is not exactly the same, I believe the solution follows the same principle: if you're proposing to do what you mention in your question, there may be something wrong in the way you're coding and some refactoring could be in order.
The take home message is that what you're asking is not the way to go when working with MVC.
The best practice is to either use a Model to place reusable functions and call them in a controller that outputs the data through a view -- or even better use helpers or libraries (for functions that may be needed repeatedly).
You can do like
$result= file_get_contents(site_url('[ADDRESS TO CONTROLLER FUNCTION]'));
Replace [ADDRESS TO CONTROLLER FUNCTION] by the way we use in site_url();
You need to echo output in controller function instead of return.
You can use the redirect() function.
Like this
class ControllerA extends CI_Controller{
public function MethodA(){
redirect("ControllerB/MethodB");
}
}
Controller to be extended
require_once(PHYSICAL_BASE_URL . 'system/application/controllers/abc.php');
$report= new onlineAssessmentReport();
echo ($report->detailView());
You can use the redirect URL to controller:
Class Ctrlr1 extends CI_Controller{
public void my_fct1(){
redirect('Ctrlr2 /my_fct2', 'refresh');
}
}
Class Ctrlr2 extends CI_Controller{
public void my_fct2(){
$this->load->view('view1');
}
}
very simple
in first controllr call
$this->load->model('MyController');
$this->MyController->test();
place file MyController.php to /model patch
MyController.php should be contain
class MyController extends CI_Model {
function __construct() {
parent::__construct();
}
function test()
{
echo 'OK';
}
}
