This error is encountered when we are going to do addition with different types of variables. See following example $a = ""; $b = 3; try{ $c = $a + $b; }catch(\Exception $e){ var_dump($e->getMessage()); } Exception is occurred. Error is " A non-numeric value encountered " There are two solutions  Solution 1 Change the value of variable $a into zero (0). So, both variables are getting the same type of value now.  $a = 0; $b = 3; try{        $c = $a + $b;         echo $c; }catch(\Exception $e){ var_dump($e->getMessage()); } Solution 2  You can simply cast $a when doing addition $a = ""; $b = 3; try{         $c =  (int) $a  + $b;         echo $c; }catch(\Exception $e){ var_dump($e->getMessage()); } Enjoy..

I have to show data from two different tables. Therefore I had to change 'loadFormData' function to satisfy that. Current implementation was as follows. /** * Method to get the data that should be injected in the form. * * @return mixed The data for the form. * @since 1.6 */ protected function loadFormData()  { // Check the session for previously entered form data. $data = JFactory::getApplication()->getUserState('com_speakee.edit.batchofcard.data', array()); if (empty($data))  { $data = $this->getItem();                         }                          return $data; } Then I changed it to get data from another table called 'Discount' by calling table of 'Discount' and got table properties by primary key.  /** * Method to get the data that should be injected in the form. * * @return mixed The data for the form. * @since 1.6 */ protected function loadFormDat

There was a requirement from one of our customers to select Google fonts which we were using in front end pages in Tiny mice editors in Joomla 2.5 back end. I couldn't find a plug-in which provides this functionality from the back end. There are few plug-ins which can be used to enable Google fonts or font.com fonts by selectors (like class or ids).   Then I went through the source code of tiny mice editor plug-in found a way add new fonts. It was a bad thing when we think about joomla updates. But with client perspective it was a good solution I think. You are welcome to discuss with regards pros and cons.  Add new fonts here Edit editor_template.js file in  media\editors\ tinymce\ jscripts\ tiny_mce\ themes\ advanced\ editor_template.js Search for 'theme_advanced_fonts' or 'Arial' or 'georgia'. There are few places of 'theme_advanced_fonts'. You need to find correct place.  theme_advanced_fonts:"Andale Mono=andale mono,times;Arial=aria

I got this fatal error when I'm going to print shipment. There are two solutions given by community. First Solution: Comment out __construct and __destruct methods in lib/Zend/Pdf/FileParserDataSource.php as follows //    abstract public function __construct();     /**      * Object destructor. Closes the data source.      *      * May also perform cleanup tasks such as deleting temporary files.      */ //    abstract public function __destruct(); Second Solution: simply change the constructor function of lib/Zend/Pdf/FileParserDataSource.php         abstract public function __construct(); TO     abstract public function __construct($filePath);

I use following code to update magento products without effecting tier prices. Because my earlier code cleared all tier prices after run code.

I had to transfer k-ecommerce customer data to magento. I created csv file according to magento customer data upload csv that I got from data profile -> export customer profile. But there was a problem to encrypt password to match with magento. I googled and found this. I will share with others for their reference. Thanks Edward // Change the paths according to your environment require_once 'app/Mage.php'; umask(0); $app = Mage::app('default'); // Instantiate the core encryption model $obj = Mage::getModel('core/encryption'); // Instantiate the core helper $helper = Mage::helper('core'); //Set the encryptions helper $obj->setHelper($helper); // Get the password's hash $enc_pwd = $obj->getHash($pwd, 2); // To validate password, use this. It will return 1 if it is correct echo $obj->validateHash($pwd, $enc_pwd);

Add following after $_item = $this->getItem() ; in checkout/cart/item/default.phtml $_tierPricing = $this->getLayout()->createBlock('catalog/product_view', 'product.tierprices', array( 'product_id' => $_item->getProductId())); $_tierPricing->setTemplate('catalog/product/view/tierprices.phtml'); To print price info: <?php echo $_tierPricing->getTierPriceHtml();?> OR If you want retrieve tier prices for any other purposes, just for show discounts etc. Use followings. $custom = Mage::getModel('catalog/product')->load($_item->getProductId());  var_dump($custom->getTierPrice());
