Magento: Get all the values of a Magento EAV for a particular attribute code

If you have ever wondered how to get all the values of any EAV attribute for products in Magento, then this is the workaround for you:

$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'color'); //here, "color" is the attribute_code

$allOptions = $attribute->getSource()->getAllOptions(true, true);

foreach ($allOptions as $instance) {

    $myArray[$instance['value']] = $instance['label'];

}

Mage::log($myArray);

You will get list of all colors in an array called “myArray” in value => label format.

Magento 1.5: Cannot login to admin panel after fresh install

After installing magento 1.5, I tried to login to the admin panel with correct username and password, but it does not let me in without any error message. This is due to cookie problem in magento and can be fixed as below:

Open this file in your favorite editor: app/code/core/Mage/Core/Model/Session/Abstract/Varien.php

Comment lines that says like (probably line number 81 to 83)

$this->getCookie()->getDomain(),

$this->getCookie()->isSecure(),

$this->getCookie()->getHttponly()

to

//$this->getCookie()->getDomain(),

//$this->getCookie()->isSecure(),

//$this->getCookie()->getHttponly()

Now you could login to your admin panel without any problem.
