{block}

{block} is used to define a named area of template source for template inheritance. For details see section of Template Interitance.

The {block} template source area of a child template will replace the correponding areas in the parent template(s).

Optionally {block} areas of child and parent templates can be merged into each other. You can append or prepend the parent {block} content by using the append or prepend option flag with the childs {block} definition. With the {$smarty.block.parent} the {block} content of the parent template can be inserted at any location of the child {block} content. {$smarty.block.child} inserts the {block} content of the child template at any location of the parent {block}.

{blocks}'s can be nested.

Attributes:

Attribute Name Type Required Default Description
name string Yes n/a The name of the template source block

Option Flags (in child templates only):

Name Description
append The {block} content will be be appended to the content of the parent template {block}
prepend The {block} content will be prepended to the content of the parent template {block}
hide Ignore the block content if no child block of same name is existing.
nocache Disables caching of the {block} content
