What does this do?
Find the first non-empty content block in the tree starting from current page and going up to the root page.
How do I use it?
Insert the tag into your template/page like: {find_content block="text" default="default value" assign="variable"}
What parameters does it take?
- (required) block - the name of the content block to find.
- (optional) default - if no filled content block is found, the default value is returned. If no default specified, an empty string is returned.
- (optional) assign - name of a Smarty variable to which the result is assigned.
