 Posted: Mon Feb 22, 2016 4:37 pm Post subject: Extended templates and use of $smarty.current_dir/.template |
 |
|
My code is as follows:
content.tpl:
| Code: |
{* Smarty *}
{extends file='PageContentLayout.tpl'}
|
PageContentLayout.tpl
| Code: |
{* Smarty *}
{block name="file_name"}
<p>{$smarty.current_dir}</p>
<p>{$smarty.template}</p>
{/block}
{block name="other_content"}
...
{* blah... *}
...
{/block}
|
In earlier versions of smarty, this code would print the template name and path of the file: content.tpl.
However, I've just upgraded to 3.1.29, and it now seems that it's the name of the base file PageContentLayout.tpl that is being printed.
I assume that this is a deliberate design change in different versions of Smarty. However, what I'd like to know is what the best way to achieving the former functionality is?
Thanks, |

Your template doesn't exactly says what is the functionality you want to achieve. Knowing real filesystem path is of no concern for template.
If you need some debug data, enable debugging. It will be there. |

I'm not sure that it really matters why I'm asking how this works. Clearly it is important for me to be able to retrieve the "path/filename" of the extending template (rather than the extended template), else I wouldn't be asking the question!
Since you did ask: the framework I'm using uses the name of the file to pass back to PHP, in order to call a class of the same name as the template file. This only works if the filename is derived from the extending file! |

In Smarty versions below template inheritance was a compile time process and the resulting code was merged into one compiled template file, in your case the content compiled template. This did have a lot of restrictions an short comings.
Since 3.1.28 it's a run time process child and parent template have their own compiled template files. Now {$smarty.template} does return the logical correct answer because it's called in PageContentLayout.
Solution
content.tpl
| Code: | {extends file='PageContentLayout.tpl'}
{$dir = $smarty.current_dir}
{$template = $smarty.template} |
PageContentLayout.tpl
| Code: | {block name="file_name"}
<p>{$dir}</p>
<p>{$template}</p>
{/block} |
