{block} is used to define a named area of template source for template
inheritance. For details see section of Template
Inheritance.
The {block} template source area of a child template will replace the
corresponding 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 child's {block}
definition. With {$smarty.block.parent} the {block} content of
the parent template can be inserted at any location of the child
{block} content. {$smarty.block.child} inserts the {block} content
of the child template at any location of the parent {block}.
{blocks}'s can be nested.
| Attribute Name | Required | Description |
|---|---|---|
| name | yes | The name of the template source block |
| assign | no | The name of variable to assign the output of the block to. |
Note
The assign attribute only works on the block that actually gets executed, so you may need to add it to each child block as well.
| Name | Description |
|---|---|
| append | The {block} content will 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 |
