 Posted: Thu Jul 31, 2003 1:29 pm Post subject: prefilters accessing smarty object variables |
 |
|
Just working on a prefilter that will cater for second delimiter. I'm having trouble though accessing smarty variables from within the prefilter. This might be more a php thing -
Here's the code:
| Code: |
function smarty_prefilter_secondDelimiters($tpl_source, &$smarty) {
print "a".$smarty->second_left_delimiter."<br>";
print "c".$smarty->left_delimiter."<br>";
return $tpl_source;
}
$smarty = new Smarty;
$smarty->left_delimiter = "<!--[";
$smarty->right_delimiter = "]-->";
$smarty->second_left_delimiter = "[";
$smarty->second_right_delimiter = "]";
print "p".$smarty->second_left_delimiter."<br>";
$smarty->register_prefilter("smarty_prefilter_secondDelimiters");
$smarty->display( ... );
|
The print statements prepended with p&c print ok, but the a prepended print shows a<br>.
That is the second delimiter doesn't seem to be available in the prefilter, but can be seen outside of the prefilter. The first delimiter can be seen inside the prefilter.
Any help is greatly appreciated,
Andy. |

the object passed to your prefilter as $smarty is actually not the $smarty whose display-method was called, but an instance of the Smarty_Compiler class.
an ugly quick fix would be:
[php:1:3f60cf9933]
function smarty_prefilter_secondDelimiters($tpl_source, &$compiler) {
global $smarty;
print "a".$smarty->second_left_delimiter."<br>";
print "c".$smarty->left_delimiter."<br>";
return $tpl_source;
}
[/php:1:3f60cf9933]
unfortunately i don't know a nicer solution without modifying Smarty.class.php |

cheers messju.
I just came across your post outlining a new release of smarty which will allow member functions to be passed to prefilters. When this comes out it should allow for a cleaner solution this problem. I might just hard code the delimiters till it does.
