仅从 Smarty 中的路径获取目录名称

Question

I cannot assign my own PHP function. (I just have access to the TPL file).

So far I got {$smarty.server.PHP_SELF} , which returns something like /foo/bar.xin . With built in functions, I'd like to get /foo/ .

Answer 1

{$smarty.server.PHP_SELF | dirname} {$smarty.server.PHP_SELF | dirname} will return /foo assuming the dirname function is enabled (see php_modifiers in Smarty security settings ).

Answer 2

As I noted, {php} tags are deprecated, but you can do the following:

{php}
$php_self = $_SERVER['PHP_SELF'];
$path = substr($php_self, 0, strrpos($php_self, '/'));
// assign a variable to Smarty
$this->assign('path',$path);
{/php}
Path: <strong>{$path}</strong>

I haven't been able to test this, since I don't have a parser at my disposal, but it follows the example on the Smarty documentation page:

http://www.smarty.net/docs/en/language.function.php.tpl

Answer 3

{$smarty.server.DOCUMENT_ROOT}  

will return server path
