{extends} tags are used in child templates in template inheritance for
extending parent templates. For details see section of Template
Inheritance.
-
The
{extends}tag must be on the first line of the template. -
If a child template extends a parent template with the
{extends}tag it may contain only{block}tags. Any other template content is ignored. -
Use the syntax for template resources to extend files outside the
$template_dirdirectory.
Attributes
| Attribute | Required | Description |
|---|---|---|
| file | Yes | The name of the template file which is extended |
Note
When extending a variable parent like
{extends file=$parent_file}, make sure you include$parent_filein the$compile_id. Otherwise, Tplix cannot distinguish between different$parent_files.
Examples
{extends file='parent.tpl'}
{extends 'parent.tpl'} {* short-hand *}

and {block}.
