{extends} {#language.function.extends}
|
|
=========
|
|
|
|
`{extends}` tags are used in child templates in template inheritance for
|
|
extending parent templates. For details see section of [Template
|
|
Inheritance](#advanced.features.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](#resources) to extend files
|
|
outside of the [`$template_dir`](#variable.template.dir) directory.
|
|
|
|
> **Note**
|
|
>
|
|
> When extending a variable parent like `{extends file=$parent_file}`,
|
|
> make sure you include `$parent_file` in the
|
|
> [`$compile_id`](#variable.compile.id). Otherwise Smarty cannot
|
|
> distinguish between different `$parent_file`s.
