{block}
{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.
Attributes
| 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.
Option Flags (in child templates only):
| 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 |
