I need help with the following error:
Fatal error: Call to a member function getno_cart_button() on a non-object in /var/home/hifi-studio_at/www/app/design/frontend/default/theme582/template/catalog/product/compare/list.phtml on line 134
This error occurs only in the compare-list. I made an Attribute called "no_cart_button", if it is checked, the product does not show the "Cart-Button" any more, but instead a "Anfrage (Ask)" linking to a Contact-Page. On all other lists and grids it does work. But why no here? This is the code I used:
<!-- // Warenkorb in Anfrage verändern // Start // -->
<?php if($_product->getno_cart_button()){ ?> <div class="add-to-cart"><button type="button" title="<?php echo $this->__('Anfrage') ?>" class="button btn-cart" onClick="parent.location='/kontakt'"><span><span><?php echo $this->__('Anfrage') ?></span></span></button></div> <?php }
else { ?> <p><button type="button" title="<?php echo Mage::helper('core')->quoteEscape($this->__('Add to Cart')) ?>" class="button btn-cart" onclick="setPLocation('<?php echo $this->helper('catalog/product_compare')->getAddToCartUrl($_item) ?>', true)"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button></p> <?php } ?>
<?php else: ?>
<!-- // Warenkorb in Anfrage verändern // ENDE // -->
This Error also occurs only with Products that have this attribute. Others don't show the cart button nor the error.
Any suggestions? Thanks!
The full code: compare/list.phtml

Solución
While in the list.phtml the code goes like
<?php foreach ($_productCollection as $_product):
// show the data for $_product
// [...]
, the code in the compare file is like:
<?php foreach($this->getItems() as $_item):
// show the data for $_item
// $_product? I don't know what that is
// [...]
You could try to do $_item->getNoCartButton() and see if this works.
If it doesn't, it means that the attribute "no_cart_button" is not
loaded for this object. You then have several options:
- first, you should do
get_class($_item)to know which object you're dealing with; I don't think it's a product-object - the
$_itemshould, however, have methods likegetProduct()orgetProductId() - as soon as you have the product, try to
getNoCartButton()from that object - if it does not work, you could do a load:
Mage::getModel('catalog/product')->load($productId)->getNoCartButton(). You really shouldn't do this, though, as it will crush your performance - you could use
Mage::getModel('catalog/product')->getResource()->getRawAttributeValue($productId,'no_cart_button', $storeId)which would only add a small query to your page, but still for each product you have in compare - the best solution would be to check the Block-file and find the place where the product collection gets loaded. Then do
$collection->addAttributeToSelect('no_cart_button'), which allows you to do something like$_item->getProduct()->getNoCartButton()in the
list.phtml.
BTW, as you might have noticed, it's convention to use camel case when working with Magento. I know that getno_cart_button() works, but you should really use getNoCartButton() or getData('no_cart_button').
Otros consejos
Actually your first lines, the change from $_product to $_item an the change from No_Cart_Button to NoCartButton worked. Both changes are relevant!
