 Posted: Wed Sep 28, 2011 5:53 pm Post subject: Absolute path doesn't work |
 |
|
Hi,
I updated Smarty to version 3.1.1 and suddenly all of my pages don't work.
Previously the following syntax worked:
$smarty->fetch('/page.tpl');
Now it doesn't. I've noticed that removing leading / from the path makes it works.
Also paths used in {include} and {extends} have the same issue.
Can anybody knows how to turn on backward compatibility? |

As of Smarty 3.1 /foo.tpl means /foo.tpl - / being root, being the root of your system. Absolute paths are, as the name says, absolute. thus they're not relative to a template_dir. if you want that, ./foo.tpl is your friend (as of Smarty 3.1.1).
As of Smarty 3.1.1 you've got the following options:
| Code: | $smarty->fetch("foo.tpl"); // translates to $template_dir/foo.tpl
$smarty->fetch("./foo.tpl"); // translates to $template_dir/foo.tpl
$smarty->fetch("../foo.tpl"); // translates to $template_dir/../foo.tpl
$smarty->fetch("/foo.tpl"); // translates to /foo.tpl |
This applies to fetch() and include() likewise. From within the template, {include} and {extends} allow:
| Code: | {include "foo.tpl"} {* translates to $template_dir/foo.tpl *}
{include "./foo.tpl"} {* translates to $current_template_path/foo.tpl *}
{include "../foo.tpl"} {* translates to $current_template_path/../foo.tpl *}
{include "/foo.tpl"} {* translates to /foo.tpl *} |
There is no backward compatibility flag for this.
a simple regular expression should help you find the spots you need to adjust:
| Code: | | \{(include|extends).+?["']/ |
and | Code: | | ->(fetch|display)\(\s*["']/ |
should find most if not all occurrences.

I think you may have uncovered an unfortunate bug present in Smarty 3.0, which was corrected in 3.1.
| Code: | | $smarty->fetch('/page.tpl'); |
This should indeed load the template from the system root. Smarty 2 behaved this way, and Smarty 3.1 also behaves this way. (I believe) Smarty 3.0 incorrectly loaded the template from the template_dir root. This behavior would carry over to {include ...} and {extends ...}. You must use one of the following:
| Code: | | $smarty->fetch('page.tpl'); |
| Code: | | $smarty->fetch('./page.tpl'); |
Smarty 2 also handled the ./ syntax OK within display() and fetch(), as does 3.1. The ../ syntax is new and does not make much sense to use with fetch() or display(), but comes in handy with {include ...} |

Thanks for the answers. When I swap
| Code: | | $smarty->fetch('/page.tpl') |
to
| Code: | | $smarty->fetch('page.tpl') |
it works.
But this one doesn't:
| Code: | | $smarty->fetch('./page.tpl') |
Any idea, why? (./ works in {include} and {extends} but not in fetch method). |

| Posted: Mon Oct 03, 2011 2:57 pm Post subject: using ../subdir/template.tpl from fetch |
|
|
smarty->fetch('../subdir/template.tpl from fetch');
we use this a lot to mean:
"find a template relative to the current template_dir..but 'up and across' into a another subdir"
upgrading to 3.1.x breaks this. What do you suggest as an alternative syntax? This?
smarty->fetch('./../subdir/template.tpl from fetch');
will that work? |

I'm not so sure I see the necessity for "../subdir". From where I stand this looks like an ugly hack, considering you _are_ able to register multiple directories with $template_dir. Since 3.1 you're even able to access them specifically: | Code: | $smarty->setTemplateDir(array(
'group1' => 'templates/group1',
'group2' => 'templates/group2',
'base' => 'templates/base',
));
$smarty->fetch('foo.tpl'); // checks templates/group1/foo.tpl then templates/group2/foo.tpl then templates/base/foo.tpl
$smarty->fetch('[group2]foo.tpl'); // checks templates/group2/foo.tpl only |
Anyways, the current SVN trunk has a fix for your issue. Use the trunk, or wait for the (soon to come?!) Smarty 3.1.2
