Add module in artical in joomla

To insert a module inside an article, use the {loadposition xx} command, as follows:
Create a module and set its position to any value that doesn’t conflict with an existing template position. You can type in the position value instead of selecting it from the drop-down list. For example, use the position myposition.
Assign the module to the Menu Items that contain the articles that you want the module to show in. You can also just assign the module to all Menu Items.
Edit the articles where you want this module to appear and insert the text {loadposition myposition} in the article at the place where you want the module.

Step 1 – Go to app/code/local/Webkul/Faq/Block here webkul is namespace and faq is module name , under your _prepareLayout() function add this code
public function _prepareLayout()
{
if (Mage::getSingleton(‘cms/wysiwyg_config’)->isEnabled() && ($block = $this->getLayout()->getBlock(‘head’))) {
$block->setCanLoadTinyMce(true);
}
return parent::_prepareLayout();
}
Then go to app/code/local/Webkul/Faq/Block/Adminhtml/Faq/Edit/Tab
and add following code in your _prepareForm() function below your setform() . $this->setForm($form);
$wysiwygConfig = Mage::getSingleton(‘cms/wysiwyg_config’)->getConfig(array(‘add_variables’ => false, ‘add_widgets’ => false,’files_browser_window_url’=>$this->getBaseUrl().’admin/cms_wysiwyg_images/index/’));
then define this as $fieldset
$fieldset->addField(‘body’, ‘editor’, array(
‘name’ => ‘body’,
‘label’ => Mage::helper(‘faq’)->__(‘Content’),
‘title’ => Mage::helper(‘faq’)->__(‘Content’),
‘style’ => ‘width:700px; height:500px;’,
‘state’ => ‘html’,
‘config’ => $wysiwygConfig,
‘wysiwyg’ => true,
‘required’ => true,
));
