Magento Code to get General Store Information

Most of the time we want to access Store Contact info at different places of our magento site to do this we have a very simple and useful code i.e

echo Mage::getStoreConfig('general/store_information');

This code will fetch you an array containing complete store which is provided at backend From System->Configuration->General->Store Information. use address

echo Mage::getStoreConfig('general/store_information/address'); 

use phone no

echo Mage::getStoreConfig('general/store_information/phone'); 

or you can get using

$info = Mage::getStoreConfig('general/store_information');
store name : $info['name']
store address : $info['address']
store Phone : $info['phone']

Magento: Adding New attributes in Category General Information

Add Below code to any file and change with my_attribute to your attribute than run that file. so for example if you past it in category/view.phtml file than open any category page from frontside and Attribute was created. see in backend category page. it will be done dont forgot to remove this code from that file after attribute was created.

$setup = new Mage_Eav_Model_Entity_Setup('core_setup');
$setup->addAttribute('catalog_category', 'my_attribute', array(
    'group'         => 'General',
    'input'         => 'text',
    'type'          => 'varchar',
    'label'         => 'My Attribute',
    'backend'       => '',
    'visible'       => 1,
    'required'      => 0,
    'user_defined' => 1,
    'global'        => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
));

you can use it If it is a text field (textbox or textarea), this is all you have to do:

echo $_product->getMyAttribute()

If you are using a dropdown or a multiple select, you have to call it a little differently:

echo $_product->getAttributeText('my_attribute')

Magento Jextn Faq SQLSTATE[42S22]: Column not found: 1054 Unknown column 'store' in 'where clause'

When I installed  Jextn Faq  Extension I got the following error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'store' in 'where clause'

I have just comment on three lines and works for me.

app\code\community\Jextn\Faq\Model\Mysql4\Faq\collection.php

after 

public function setFirstStoreFlag($flag = false)
{
    $this->$previewFlag = $flag;
    return $this;
}

 before

public function setFirstStoreFlag($flag = false)
{
//  $this->$previewFlag = $flag;
    return $flag;
}

In same file remove If condition from  function _afterLoad() and its look like this

protected function _afterLoad()
{
//        if ($this->$previewFlag) {
        $items = $this->getColumnValues('faq_id');
        if (count($items)) {
            $select = $this->getConnection()->select()
                    ->from($this->getTable('faq_store'))
                    ->where($this->getTable('faq_store').'.faq_id IN (?)', $items);
            if ($result = $this->getConnection()->fetchPairs($select)) {
                foreach ($this as $item) {
                    if (!isset($result[$item->getData('faq_id')])) {
                        continue;
                    }
                    if ($result[$item->getData('faq_id')] == 0) {
                        $stores = Mage::app()->getStores(false, true);
                        $storeId = current($stores)->getId();
                        $storeCode = key($stores);
                    } else {
                        $storeId = $result[$item->getData('faq_id')];
                        $storeCode = Mage::app()->getStore($storeId)->getCode();
                    }
                    $item->setData('_first_store_id', $storeId);
                    $item->setData('store_code', $storeCode);
                }
            }
        }
//        }
    parent::_afterLoad();

Magento: Remove auto Breaks("br/") from product description

By Default Magento automatically adds

html tags to product descriptions for display on the customer interface.  If you have created a nice description with the WYSIWYG Editor or imported HTML descriptions you most likely want to remove this behavior.   Luckily this is not hard to do.

1. Find the file "description.phtml" here:  app/design/frontend/default/ 
2. Remove the "nl2br" tag

Before:

helper('catalog/output')->productAttribute($this->getProduct(), 
nl2br($this->getProduct()->getDescription()), 'description') ?>

After:

helper('catalog/output')->productAttribute($this->getProduct(),   
$this->getProduct()->getDescription()), 'description' ?>
