IWD Onepage Checkout的Magento致命错误

Question

I am using magento one page checkout for the quick checkout process.

It is throwing fatal error upon adding product to cart. In j2t ajax and in header cart area its showing fatal error but after reloading the page error gone and product added to shopping cart.

In PHP error log shows following error

PHP Fatal error:  Call to a member function addLink() on a non-object in /home/public_html/app/code/community/IWD/Opc/Block/Links.php on line 17

On line 17

$parentBlock->addLink($text, 'onepage', $text, true, array('_secure'=>true), 60, null, 'class="top-link-checkout"');

I've tried to disable ajax cart and also Compilation to disabled but its still throwing error.

Any idea why its showing error?

Thank you in advance :)

Answer 1

I solved this issue by myself. Thanks anyway.

If anyone have this issue. Here is the Solution for it

Go to: /Magento folder/app/code/community/IWD/Opc/Block/Links.php

Find:

if (Mage::helper('opc')->isEnable()){
        $parentBlock->addLink($text, 'onepage', $text, true,     array('_secure'=>true), 60, null, 'class="top-link-checkout"');
    }
else{
        $parentBlock->addLink($text, 'checkout', $text, true,     array('_secure'=>true), 60, null, 'class="top-link-checkout"');
    }

    return $this;
}

Replace it with:

if ($parentBlock = $this->getParentBlock()) {
         $text = $this->__('Checkout');
         $parentBlock->addLink($text, 'checkout', $text, true, array(), 60, null, 'class="top-link-checkout"');
     }
     return $this;
 }

Clear cache and cookies and you're done :)

A slightly better approach (until IWD fixes this, that is) is do do what Muk suggested and to just wrap that whole block around in an "is_object" check.

if (is_object($parentBlock)) {
  $text = $this->__('Checkout');
  if (Mage::helper('opc')->isEnable()){
    $parentBlock->addLink($text, 'onepage', $text, true, array('_secure'=>true), 60, null, 'class="top-link-checkout"');
  } else {
    $parentBlock->addLink($text, 'checkout', $text, true, array('_secure'=>true), 60, null, 'class="top-link-checkout"');
  }
}
