Magento 1.9 Product Attribute – Safely Use getAttributeText

attributesmagento-1.7magento-1.9productproduct-attribute

If I call getAttributeText on a non existing attribute, eg:

$product->getAttributeText('some-non-existing-field');

I get the fatal error:

Fatal error: Call to a member function getSource() on a non-object

Which I can't even try-catch because its fatal.

Different magento stores have different attributes (And also different products got different attributes), so how can I access attributes in a safe way that even if they are undefined I won't get fatal (for example get null or empty string if non-existence)?

or as an alternative, how can I test if attribute exists first?

Thanks!

Given that the product is already loaded (including this attribute), you can use getData() instead of the magic getter to be able to use a dynamic attribute code:

$attributeCode = 'custom_attribute_code');

if ($_product->getData($attributeCode) !== null){
    echo $_product->getAttributeText($attributeCode);
}

This way you have no unnecessary database queries.

Magento – Fatal Error: Call to a Member Function getId() on a Non-Object

Replace your code from:

<?php 

$product_id = Mage::registry('current_product')->getId();
$_product=Mage::getModel('catalog/product')->load($product_id);
$attribute = $_product->getResource()->getAttribute('cod_available');
if ($attribute)
{
    echo $attribute_value = $attribute ->getFrontend()->getValue($_product);
}
?>

To:

view.phtml

<?php 
$currentProduct = Mage::registry('current_product');
if($currentProduct) {
    $attribute = $currentProduct->getResource()->getAttribute('cod_available');
    if ($attribute) {
        echo $attribute_value = $attribute ->getFrontend()->getValue($_product);
    }
}
?>

other .phtml (But must be available getproduct() function in block file)

<?php 

$product = $this->getProduct();
if($product->getId()) {
    $attribute = $product->getResource()->getAttribute('cod_available');
    if ($attribute) {
        echo $attribute_value = $attribute ->getFrontend()->getValue($_product);
    }
}
?>
