|
|
Every so often I come over some longer piece of template code that I would like to comment out temporarily or comment out "for real" but preserve for a longer time. The current {* *} doesn't allow putting it as a wrap around that code. I assume there is a problem with finding the end of the comment. What about using the same open and close syntax as with other Smarty elements?
Code: | {* ... /*} comment that can contain other Smarty elements. |

you can't nest the comment tags, too many problems. Its the same in PHP with /* */ blocks, you can't nest them since the ending tags are ambiguous. You could do a work around though, make up your own comment tag syntax:
Code: | {***
Put any {* smarty *} stuff {in} here.
***} |
Then use a prefilter to snip out these comment blocks before compile time. Something like:
Code: | return preg_replace('!\{\*\*\*.*\*\*\*\}!Ums','',$content); |

Ok, maybe "nested" comments was the wrong term. I mean a mix of comments and code. What I want is exactly the same that I can do with /* */ in php. Just put them around any code block and it's commented out. This doesn't really work with Smarty. (I'm ok with comments not allowed within comments.)
e.g., that works:
Code: | {* some text here *} |
that sometimes does, but sometimes does not:
Code: |
{*
{lenghty smarty code block including text and html}
*}
|
I can't give you an example at the moment. I just ran into this problem regularly with Smarty 2 and found that it still happens with Smarty 3 the day I posted it. As I understand wrapping the smarty code with {* *} should always work, just not if another comment is contained, right? |

That should work. A demonstration of the problem would be a big help. |

Ok, next time I run into it I'll add here. Of course, it's possible that I accidentally had a nested comment somewhere in that code. We'll see. Happy holdays! |
