I am struggling to understand how to call sub controllers from a joomla component. What are to be placed in the controllers folder?
I have the entry point of my component like -
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// require helper file
JLoader::register('TieraerzteHelper', dirname(__FILE__) . DS . 'helpers' . DS . 'my_helper.php');
// import joomla controller library
jimport('joomla.application.component.controller');
$controller = JController::getInstance('MyController');
// Get the task
$jinput = JFactory::getApplication()->input;
$task = $jinput->get('task', "", 'STR' );
// Perform the Request task
$controller->execute($task);
// Redirect if set by the controller
$controller->redirect();
Then if I want to call a controller, which is placed in the controllers folder, how do I do that?
You do a task=controller.function
As an example: You want to call the MycomponentControllerFoo in /controllers/foo.php and execute the function bar(). You use the following URL to call this:
index.php?option=com_mycomponent&task=foo.bar
Or you can use a form where there is a hidden task field.

it cant seem to load the common helper that i created in the helper folder
to load the admintle for my codeigniter project.
enter code here
<?php
function public_url($url){
return base_url('public/'.$url)
}
You are calling another helper that is being used in your helper.
So you need to load the url helper in your controller before you load yours.
i.e.
$this->load->helper('url'); // Core URL helper for base_url()
$this->load->helper('common_help'); // This is your common_help_helper.php
And you have a missing ; in your function
function public_url($url) {
return base_url('public/' . $url); // <<< Missing ; in your code
}
I'm corrently develop webs application for selling products online by using Codeigniter and upgrade from Ci2.2.1 to CI3.0.
However I've meet an errors 404 Page Not Found when I enter domain name on url not yet called any controller by hoped default_controller will load instead of type my main controller.
Notes: It is working on Ci2.2.1 and it stop work when upgrade to CI3.0.
It is working if I type any characters or any Controller after domain name(http://localhost/Ecom3/sometroller) But it is coudn't call default_controller and keep empty or blank after domain (http://localhost/Ecom3/).
Errors log: ERROR - 2015-04-24 03:48:57 --> 404 Page Not Found: /index
Please check my webs structure below:
Main->Main_controller->MY_controller->CI_Controller
My purpose to make it easy to controller the templates.
In MY_controller I've use __autoload() function
function __autoload($class){
if (strpos($class, 'CI_') !== 0)
{
if (file_exists($file = APPPATH . 'libraries/' . $class .'.php'))
{
include_once $file;
}
}
}
And I have confige route as below
$route['default_controller'] = "main/Main";
$route['(:any)'] = 'main/main/index/$1';
$route['c'] = 'cat/cat/index/$1';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
The problem:
My url can't be blank after I type domain or after forword slash as below image
Please help
I try your code and get 404 when Main.php in your controller place inside controller/main folder. but when im move Main.php into controller folder, default controller to Main has working. then im try to debuging and see:
// Is the method being specified?
if (sscanf($this->default_controller, '%[^/]/%s', $class, $method) !== 2)
{
$method = 'index';
}
in core/Router.php
thats mean codeigniter3 are not allowed you to set default_controller in sub folder. you must put default_controller in app/controller/ to make it works.
in config/router.php
change this:
$route['default_controller'] = "main/Main";
TO:
$route['default_controller'] = "Main";
then move your controller file :
app/controller/main/Main.php
TO
app/controller/Main.php
I have a script that uploads to a folder and I want to display a view after the upload is done, successful or not.
/component
/admin/
/views/
/components/
view.html.php
/tmpl/
default.php
modal.php // I want to load and output this file from controller.php
component.php
controller.php
/site/
I would like to do something like this, in my controller
$view = $this->getView(/* params for modal.php to load*/); //get the view
$this->view->display();
thank you
Try using:
$view = $this->getView( 'components', 'html' );
$view->setLayout('modal');
$view->display();
or
JRequest::setVar('view', 'components');
JRequest::setVar('layout', 'modal');
Can anyone please help me with the process flow through which the Joomla Itemid parameter ends up being the highlighted menu item?
I have embedded a 3rd party application in Joomla and by temporarily changing the php environment within the application.
I am able to get joomla html and insert the 3rd party html by replacing a token.
Simplified Code:
if ($_SERVER['REQUEST_METHOD'] == 'GET' ) {
$_SERVER['REQUEST_METHOD'] = '';
}
$_SERVER['REQUEST_URI'] = '/joomla/index.php?view=mycom&option=com_mycom&Itemid=103';
$_SERVER['SCRIPT_NAME'] = $_SERVER['PHP_SELF'] = '/joomla/index.php';
$_SERVER['QUERY_STRING'] = 'view=mycom&option=com_mycom&Itemid=103';
ob_start();
require_once '/joomla/index.php';
$joomlaHTML = ob_get_clean();
echo str_replace($replacementToken, $thirdPartyHTML, $joomlaHTML);
In v1.5.x, the menu item with ID 103 is properly highlighted but in v2.5.6, it isn't and the Home item is always highlighted. I think it used to be highlighted correctly in v1.6.x and earlier versions of 2.5.x as well but not sure.
I wanted to find how the process flows (where this is set) so I can see what tweaks I need to make.
DELETED WRONG INFO
Thanks Dayo! you saved my day with this:
// force highlight the external url menu item
$Itemid = JRequest::getVar('Itemid');
$menu = JSite::getMenu();
$menu->setActive($Itemid);
I don't fully understand the breadcrumb part, but I managed to get it working by editing my component's controller.php to read:
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// force highlight the external url menu item
$Itemid = JRequest::getVar('Itemid');
$menu = JSite::getMenu();
$menu->setActive($Itemid);
// force fix the breadcrumb
$app = JFactory::getApplication('site');
$pathway =& $app->getPathway();
$bcrumbs = &JPathway::getInstance('site');
// import Joomla controller library
jimport('joomla.application.component.controller');
/**
* MyCom Component Controller
*/
class MyComController extends JController
{
}
Look in the following File
Check the
/modules/mod_menu/mod_menu.php
File and you will see two functions has been called "getActive" and "getDefault"
Which can be find in following file
/libraries/joomla/application/menu.php
I think it can be customized easily now
I am trying to implement pagination in my CI webapp. Now I put the config for pagination inside a config file like this...
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$config['base_url'] = "http://example.com/index.php/home/index";
$config['num_links'] = "9";
$config['per_page'] = "20";
$config['total_rows'] = "200";
/* End of file pagination.php */
/* Location: ./system/application/config/pagination.php */
In my controller, I have loaded the library
$this->load->library("pagination");
And I have defined the pagination config file to be autoload in config/autoload.php
$autoload['config'] = array('pagination');
At last I called the method to create links in my view template:
<?php echo $this->pagination->create_links(); ?>
This did not create any links. The configuration is being autoloaded correctly. I checked using...
<?php echo $this->config->item("num_links"); ?> <!-- this dislayed 9 -->
What am I missing here? Just for the record, putting the config inside the controller didn't work either.
Update #1- I have found out that the config settings are loading correctly but they are not reaching the library or something like that. Inside the pagination library - I did some hard coding to find out that per_page parameter was zero in there.
Update #2- I was mistaken when I said that putting the config inline wasn't working. It is working fine. The autoload isn't working.
Regards
Finally used this code to solve my problem...
$this->config->load("pagination");
$page_limit = $this->config->item("per_page");
$config['total_rows'] = $var; // Some variable count
$this->pagination->initialize($config);
This lets me define the config items in a file as well as initialize the items I want in controller like in my case, the total no. of rows - retrieved from database.
Regards
Your autoload line in your config file should be this
$autoload['libraries'] = array('pagination');
And you must have this line in you controller after your config array, before you use create_links() etc.
$this->pagination->initialize($config);
