Custom CMS field showing widget calling code in frontend in Magento

Scenario:
I added custom field for CMS pages and wanted to show its value in sidebar.

Field type: Textarea
Wysiwyg: Enabled
Field Name: content_custom

I wanted to call a widget in content of this custom field.

For reference, I added below code to call widget:

{{widget type="cms/widget_page_link" anchor_text="My Custom Link" title="My Custom Link" template="cms/widget/link/link_block.phtml" page_id="153"}}

When I tried to show field's value in frontend, it displayed content as it was inputted from cms page:

{{widget type="cms/widget_page_link" anchor_text="My Custom Link" title="My Custom Link" template="cms/widget/link/link_block.phtml" page_id="153"}}

instead of rendering its html.

Solution: To render html instead of code calling widget, use below code:

echo Mage::helper('cms')->getBlockTemplateProcessor()->filter(Mage::getBlockSingleton('cms/page')->getPage()->getContentCustom());

Please try this code and let me know if you find any problem.

Thanks for visiting.
