Tag {extends}
|
|
=============
|
|
|
|
`{extends}` tags are used in child templates in template inheritance for extending parent templates.
|
|
The `{extends}` tag must be on before any block.
|
|
Also if a child template extends a parent template with the `{extends}` tag it may contain only `{block}` tags. Any other template content is ignored.
|
|
|
|
### {extends}
|
|
|
|
```smarty
|
|
{extends 'parent.tpl'}
|
|
```
|
|
|
|
### {block}
|
|
|
|
```smarty
|
|
{block 'bk2'}content 2{/block}
|
|
```
|
|
|
|
### {use}
|
|
|
|
Import the blocks defined in another file. Specifying blocks in this template will override those from the other file.
|
|
|
|
```smarty
|
|
{use 'blocks.tpl'} merge blocks from blocks.tpl template
|
|
|
|
{block 'alpha'} rewrite block alpha from blocks.tpl template, if it exists
|
|
...
|
|
{/block}
|
|
```
|
|
|
|
### {parent}
|
|
|
|
Uses the code from the block as defined in the parent.
|
|
|
|
```smarty
|
|
{extends 'parent.tpl'}
|
|
|
|
{block 'header'}
|
|
content ...
|
|
{parent} pase code from block 'header' from parent.tpl
|
|
content ...
|
|
{/block}
|
|
```
|
|
|
|
### {paste}
|
|
|
|
Pastes the code of any block
|
|
|
|
```smarty
|
|
{block 'b1'}
|
|
...
|
|
{/block}
|
|
|
|
{block 'b2'}
|
|
...
|
|
{paste 'b1'} paste code from b1
|
|
{/block}
|
|
|
|
```
|
|
|
|
### {$.block}
|
|
|
|
Checks if clock exists
|
|
|
|
```smarty
|
|
{if $.block.header}
|
|
block header exists
|
|
{/if}
|
|
```
