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

  • It's pretty clear that $_product is not an object in the code, presumably it's null - meaning "not defined". Where does $_product come from? – simonthesorcerer Aug 9 '18 at 20:59
  • I guess, its the product that was chosen for the compare site? Honestly, I have no Idea, on the other list.phtml it worked this way. – Benjamin Benotheus Aug 9 '18 at 23:33
  • Can you post the whole file pls? – simonthesorcerer Aug 9 '18 at 23:35
  • It sounds like the $_product variable doesn't contain anything. On another note, if your attribute is named no_cart_button, your call should be $_product->getNoCartButton(). Magento has logic built in that will parse the function name into your attribute name, but not with the way you do it. However, if you want to have less functional overhead, you are better off with $_product->getData('no_cart_button'). Doesn't solve your current problem, just some helpful advice. – Shawn Abramson Aug 10 '18 at 2:48

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 $_item should, however, have methods like getProduct() or getProductId()
  • as soon as you have the product, try to getNoCartButton() from that object
  • if it does not work, you could do a load: Mage::getModel('catalog/product')->load($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').

  • could you pls help me, in my cms page add to cart not working -> code -> justpaste.it/49eqz – zus Aug 17 '18 at 11:25
  • "not working" is not an error description. Pls ask a question here on MagentoSE with details on what is not working, which errors you get etc. – simonthesorcerer Aug 17 '18 at 11:45
-1

Actually your first lines, the change from $_product to $_item an the change from No_Cart_Button to NoCartButton worked. Both changes are relevant!
