{
// Load Wysiwyg on demand and Prepare layout
if (Mage::getSingleton(‘cms/wysiwyg_config’)->isEnabled() && ($block = $this->getLayout()->getBlock(‘head’))) {
$block->setCanLoadTinyMce(true);
}
parent::_prepareLayout();
}

step-2

app\code\local\Namespace\Modulename\Block\Adminhtml\Modulename\Edit\Tab
and find function protected function _prepareForm()
and add
$form->setHtmlIdPrefix(‘modulename’);
$wysiwygConfig = Mage::getSingleton(‘cms/wysiwyg_config’)->getConfig(
array(‘tab_id’ => ‘form_section’)
);
And add field property
$wysiwygConfig["files_browser_window_url"] = Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/cms_wysiwyg_images/index’);
$wysiwygConfig["directives_url"] = Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/cms_wysiwyg/directive’);
$wysiwygConfig["directives_url_quoted"] = Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/cms_wysiwyg/directive’);
$wysiwygConfig["widget_window_url"] = Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/widget/index’);
$wysiwygConfig["files_browser_window_width"] = (int) Mage::getConfig()->getNode(‘adminhtml/cms/browser/window_width’);
$wysiwygConfig["files_browser_window_height"] = (int) Mage::getConfig()->getNode(‘adminhtml/cms/browser/window_height’);
$plugins = $wysiwygConfig->getData(“plugins”);
$plugins[0]["options"]["url"] = Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/system_variable/wysiwygPlugin’);
$plugins[0]["options"]["onclick"]["subject"] = “MagentovariablePlugin.loadChooser(‘”.Mage::getSingleton(‘adminhtml/url’)->getUrl(‘adminhtml/system_variable/wysiwygPlugin’).”‘, ‘{{html_id}}’);”;
$plugins = $wysiwygConfig->setData(“plugins”,$plugins);
$fieldset->addField(‘fieldname’, ‘editor’, array(
‘name’ => ‘fieldname’,
‘label’ => Mage::helper(‘modulename’)->__(‘Content’),
‘title’ => Mage::helper(‘modulename’)->__(‘Content’),
‘style’ => ‘width:700px; height:300px;’,
‘wysiwyg’ => true,
‘required’ => false,
‘state’ => ‘html’,
‘config’ => $wysiwygConfig,
));

step-3
Go to following path and open modulename.xml if its not available than create id
app\design\adminhtml\default\default\layout
and add
<?xml version=”1.0″?>
<layout>
<modulename_adminhtml_controllername_index>
<reference name=”content”>
<block type=”modulename/adminhtml_blockname” name=”blockname” />
</reference>
</modulename_adminhtml_controllername_index>
<modulename_adminhtml_controllername_edit>
<update handle=”editor”/>
</modulename_adminhtml_controllername_edit>
</layout>

if you want to Display editor's content in front side use below code .

$_cmsHelper = Mage::helper(‘cms’);
$_process = $_cmsHelper->getBlockTemplateProcessor();
echo $_process->filter($item['content']);

Adding Javascript validation to your own forms is extremely simple. First, you need to create a Form (form.js) object to represent your form.

<script type="text/javascript">
//< ![CDATA[
  var myForm= new VarienForm('formId', true);
//]]>
</script>

example how to add validation in custom module through class name is as below:

<label for="name">Name *</label>
<input type="text" id="name" name="name" value="" class="required-entry"/>
<label for="email">Email Address *</label>
<input type="text" id="email" name="email"  class="required-entry validate-email"/>

Join custom table to product collection in magento

$collection = Mage::getModel('module/model_name')->getCollection();
$collection->getSelect()->join( array('table_alias'=>$this->getTable('module/table_name')), 'main_table.foreign_id = table_alias.primary_key', array('table_alias.*'), 'schema_name_if_different');


For Example,


$collection = Mage::getResourceModel('catalog/product_collection')

                ->addAttributeToFilter('visibility', array('neq' => 1));

Add tracking no in shipment in magento through script

1.create a csv file . In it put following fields OrderNumber,Email,TrackingNumber,Carrier . & csv's name is orders_tracking_import.csv
2 Create ordertracking.php file in your magento's root directory

<?php
    require_once("app/Mage.php");
    Mage::app();
 
    if (isset($_POST['MAX_FILE_SIZE'])) {

        $email = true;
