I am trying to display configurable options in a custom product view page. I have added following code to page but I am getting an error:


 <?php $_attributes = Mage::helper('core')->decorateArray($_product->getTypeInstance(true)->getConfigurableAttributes($_product));?>
<?php if ($_product->isSaleable() && count($_attributes)):?>
<?php foreach($_attributes as $_attribute): ?>
<dt><label class="required"><em>*</em><?php echo $_attribute->getLabel() ?></label></dt>
<dd<?php if ($_attribute->decoratedIsLast){?> class="last"<?php }?>>
<div class="input-box">
<select name="super_attribute[<?php echo $_attribute->getAttributeId() ?>]" id="attribute<?php echo $_attribute->getAttributeId() ?>" class="required-entry super-attribute-select">
<option><?php echo $this->__('Select...') ?></option>
<?php endforeach; ?>
<script type="text/javascript">
var spConfig = new Product.Config(<?php echo $this->getJsonConfig() ?>);
<?php endif;?>

Error: TypeError:
this.config is undefined

this.taxConfig = this.config.taxConfig;

I need help in solving this issue.

Thanks in advance.

  • You're missing Javascript. Compare the scripts loaded in the <head> on your custom page and on the default product page. – nachito Dec 16 '13 at 22:12
  • What is actually outputted by <?php echo $this->getJsonConfig() ?>, If you block is not of type or does not extend Mage_Catalog_Block_Product_View_Type_Configurable then you may find this information is missing. – David Manners May 20 '14 at 9:40

If you block is not of type Mage_Catalog_Block_Product_View_Type_Configurable then you could find that the function getJsonConfig is not being set-up correctly.

You should check your block type and also the return value of the function call.
