Can't access jmodulehelper load method in module helper file

Question

I am using com_ajax in joomla 2.5 - https://github.com/Joomla-Ajax-Interface/component

As I have many instances(duplicate modules) of same module from where I call to com_ajax component by jQuery ajax. So is com_ajax calls to my module's helper.php file to get data for ajax call as we know. Problem is I want to access parameters of another module instance in helper.php file which is not possible by the default call $module = JModuleHelper::getModule('mod_name_here'); so I was trying to achieve this way by passing module id to helper.php file from module's jQuery ajax call -

jimport('joomla.application.module.helper');
$input  = JFactory::getApplication()->input;
$mod_id = $input->get('module_id'); //module_id passed by ajax call             
$module = null; 
$modules = JModuleHelper::_load(); 
$total = count($modules); $name="mod_name_here";

for ($i = 0; $i < $total; $i++)
{
    // Match the name of the module
    if (($modules[$i]->name == $name || $modules[$i]->module == $name)&&($modules[$i]->id==$mod_id))
    {
        $module = $modules[$i];
        break; // Found it          
    }
}               
$params1 = new JRegistry();
$params1->loadString($module->params);

so in $params1 I am getting the settings of my desired module instance.But debugger hangs on line $modules = JModuleHelper::_load(); don't know why but when I put these same codes in a module main php file for testing, things work. So why doesn't it goes further after that line? Any alternatives?

Answer 1

I am not sure I understand your issue, because you presented no error message or something. The debugger should take you inside JModuleHelper::load() as well. My guess is that you don't provide the ItemId which is used by this function, but this is a guess.

Be advised that JModuleHelper::getModule() has two parameters:

• $name
• $title

You should be able to narrow your search by providing the title (somehow) as well.

Hope this helps.

There's no need to use JModuleHelper to retrieve module parameters in the helper class.

Every module instance is properly created and a context variable $params is assigned for paramaters usage. For instance mod_example has $params initialized, you can just call your helper class sending the whole $params, or specific variables.

For example, mod_menu works in this way, sending the layout parameter to the helper class modMenuHelper:

// no direct access
defined('_JEXEC') or die;

// Include the syndicate functions only once
require_once dirname(__FILE__).'/helper.php';

$list   = modMenuHelper::getList($params);
$app    = JFactory::getApplication();
$menu   = $app->getMenu();
$active = $menu->getActive();
$active_id = isset($active) ? $active->id : $menu->getDefault()->id;
$path   = isset($active) ? $active->tree : array();
$showAll    = $params->get('showAllChildren');
$class_sfx  = htmlspecialchars($params->get('class_sfx'));

if(count($list)) {
    require JModuleHelper::getLayoutPath('mod_menu', $params->get('layout', 'default'));
}
