How to get all attributes of an attribute group in Magento

>> Sometimes you need to display all attributes value of a particular attribute group. Then you can follow this piece of code :
    <ul>
        <?php
            $_product = $productObj;
            $attributesCollection = Mage::getResourceModel('catalog/product_attribute_collection');
            $attributesCollection->setAttributeGroupFilter(27);                    // Here 27 is Attribute Group Id.
            foreach ($attributesCollection as $attribute) {
                    if($attribute->getFrontendInput() == 'select' || $attribute->getFrontendInput() == 'boolean'){
                        echo "<li>".$attribute->getFrontendLabel()." : ".$_product->getAttributeText($attribute->getAttributeCode())."</li>";
                    }else{
                        echo "<li>".$attribute->getFrontendLabel()." : ".$_product->getData($attribute->getAttributeCode())."</li>";
                    }

            }
        ?>
    </ul>

How to add a breadcrumb to any Magento page.

>> Here's a easy solution to add breadcrumb to any page. In core block page find _prepareLayout() method.

    <?php
        public function _prepareLayout()
        {
            $breadcrumbs = $this->getLayout()->getBlock('breadcrumbs');
            $breadcrumbs->addCrumb('home', array('label'=>Mage::helper('vendor')->__('GEAR WAREHOUSE'),
                                            'title'=>Mage::helper('vendor')->__('Home Page'), 'link'=>Mage::getBaseUrl()));
            $breadcrumbs->addCrumb('my_account', array('label'=>Mage::helper('vendor')->__('My Account'),
                                            'title'=>Mage::helper('vendor')->__('My Account'), 'link'=>Mage::getBaseUrl().'customer/account'));
                                           
            $breadcrumbs->addCrumb('my_classified', array('label'=>Mage::helper('vendor')->__('Classified'),
                                            'title'=>Mage::helper('vendor')->__('My Classified'), 'link'=>Mage::getBaseUrl().'vendor'));
                                           
            $breadcrumbs->addCrumb('an_alias', array('label'=>'Edit',
                                            'title'=>'Edit Classified', 'link'=>''));
        }
    ?>
   
    By using addCrumb() method you can set your breadcrumb to any page. In your phtml page you've to write the following code :
   
    <?php echo $this->getLayout()->getBlock('breadcrumbs')->toHtml(); ?>
   
    By default this code is written in layout page. (e.g. 1column.phtml)

>> I'll show you the another way by xml:
        <reference name="root">
            <action method="unsetChild"><alias>breadcrumbs</alias></action>
            <block type="page/html_breadcrumbs" name="breadcrumbs" as="breadcrumbs">
                <action method="addCrumb">
                    <crumbName>Home</crumbName>
                    <crumbInfo><label>Home</label><title>Home</title><link>/</link></crumbInfo>
                </action>
                <action method="addCrumb">
                    <crumbName>Parent Page</crumbName>
                    <crumbInfo><label>Parent Page</label><title>Parent Page</title><link>/Parent Page link</link></crumbInfo>
                </action>
                <action method="addCrumb">
                    <crumbName>Current Page</crumbName>
                    <crumbInfo><label>Current Page</label><title>Current Page</title></crumbInfo>
                </action>
            </block>
        </reference>



  
  You can use it in your custom module xml, admin category custom layout update section and also CMS page layout update xml section.

Automatically shipment and invoice order in Magento

>> In magento to complete an order from admin you need to create an Invoice then a Shipment. If you want to make it by once click on shipment button. you can easily try this code to get the result.

     $order = $orderObj;                  // get your order object.

     if ($order->getState() == Mage_Sales_Model_Order::STATE_NEW) {
            
            try {
                if(!$order->canInvoice()) {
                    $order->addStatusHistoryComment('Order cannot be invoiced.', false);
                    $order->save();
                }
                
                //START Handle Invoice
                $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();

                $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);
                $invoice->register();

                $invoice->getOrder()->setCustomerNoteNotify(false);        
                $invoice->getOrder()->setIsInProcess(true);
                $order->addStatusHistoryComment('Automatically INVOICED.', false);

                $transactionSave = Mage::getModel('core/resource_transaction')
                    ->addObject($invoice)
                    ->addObject($invoice->getOrder());

                $transactionSave->save();
                //END Handle Invoice
                
                //START Handle Shipment
                $shipment = $order->prepareShipment();
                $shipment->register();

                $order->setIsInProcess(true);
                $order->addStatusHistoryComment('Automatically SHIPPED.', false);

                $transactionSave = Mage::getModel('core/resource_transaction')
                    ->addObject($shipment)
                    ->addObject($shipment->getOrder())
                    ->save();
                //END Handle Shipment
            } catch (Exception $e) {
                $order->addStatusHistoryComment('Exception occurred during automaticallyInvoiceShipCompleteOrder action. Exception message: '.$e->getMessage(), false);
                $order->save();
            }              
     }

Now see I've implemented it in shipment save action, means when you'll click on the shipment button to create the shipment, it'll automatically generate the invoice also. Go to app/code/core/Mage/Adminhtml/controllers/Sales/Order/ShipmentController.php
find the saveAction() method and replace it with the following code :

        public function saveAction()
        {
            $data = $this->getRequest()->getPost('shipment');
            if (!empty($data['comment_text'])) {
                Mage::getSingleton('adminhtml/session')->setCommentText($data['comment_text']);
            }
       
            try {
                $shipment = $this->_initShipment();
                if (!$shipment) {
                    $this->_forward('noRoute');
                    return;
                }
       
                $shipment->register();
               
                $order = $shipment->getOrder();
                if(!$order->canInvoice()) {
                    $order->addStatusHistoryComment('Order cannot be invoiced.', false);
                    $order->save();
                }
               
                //START Handle Invoice
                $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();
       
                $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);
                $invoice->register();
       
                $invoice->getOrder()->setCustomerNoteNotify(false);       
                $invoice->getOrder()->setIsInProcess(true);
                $order->addStatusHistoryComment('Automatically INVOICED.', false);
       
                $transactionSave = Mage::getModel('core/resource_transaction')
                    ->addObject($invoice)
                    ->addObject($invoice->getOrder());
       
                $transactionSave->save();
                //END Handle Invoice
               
                $comment = '';
                if (!empty($data['comment_text'])) {
                    $shipment->addComment(
                        $data['comment_text'],
                        isset($data['comment_customer_notify']),
                        isset($data['is_visible_on_front'])
                    );
                    if (isset($data['comment_customer_notify'])) {

                    }
                }
       
                if (!empty($data['send_email'])) {
                    $shipment->setEmailSent(true);
                }
       
                $shipment->getOrder()->setCustomerNoteNotify(!empty($data['send_email']));
                $responseAjax = new Varien_Object();
                $isNeedCreateLabel = isset($data['create_shipping_label']) && $data['create_shipping_label'];
       
                if ($isNeedCreateLabel && $this->_createShippingLabel($shipment)) {
                    $responseAjax->setOk(true);
                }
       
                $this->_saveShipment($shipment);
       
                $shipment->sendEmail(!empty($data['send_email']), $comment);
       
                $shipmentCreatedMessage = $this->__('The shipment has been created.');
                $labelCreatedMessage    = $this->__('The shipping label has been created.');
       
                $this->_getSession()->addSuccess($isNeedCreateLabel ? $shipmentCreatedMessage . ' ' . $labelCreatedMessage
                    : $shipmentCreatedMessage);
                Mage::getSingleton('adminhtml/session')->getCommentText(true);
            } catch (Mage_Core_Exception $e) {
                if ($isNeedCreateLabel) {
                    $responseAjax->setError(true);
                    $responseAjax->setMessage($e->getMessage());
                } else {
                    $this->_getSession()->addError($e->getMessage());
                    $this->_redirect('*/*/new', array('order_id' => $this->getRequest()->getParam('order_id')));
                }
            } catch (Exception $e) {
                Mage::logException($e);
                if ($isNeedCreateLabel) {
                    $responseAjax->setError(true);
                    $responseAjax->setMessage(
                        Mage::helper('sales')->__('An error occurred while creating shipping label.'));
                } else {
                    $this->_getSession()->addError($this->__('Cannot save shipment.'));
                    $this->_redirect('*/*/new', array('order_id' => $this->getRequest()->getParam('order_id')));

Create custom pagination in magento

Hope you known about block, xml in Magento.
Here is an extracted code that would help you to create pagination with custom collection in magento.

    >> First paste the following code in your block class (e.g. product.php)
       
        <?php
        class example extends parentclass
        {
            private $_itemPerPage = 2;
            private $_pageFrame = 8;
            private $_curPage = 1;
           
            public function getCollection($collection = 'null')
            {
                if($collection != 'null'){
                    $page = $this->getRequest()->getParam('p');
                    if($page) $this->_curPage = $page;
                   
                    $collection->setCurPage($this->_curPage);
                    $collection->setPageSize($this->_itemPerPage);
                    return $collection;
                }
            }
           
            public function getPagerHtml($collection = 'null')
            {   
                $html = false;
                if($collection == 'null') return;

        <?php if($this->getPagerHtml($this->getProductCollection())):?>        // pass the default collection as parameter
        <div class="pages">
