 Posted: Thu Dec 11, 2014 11:33 am Post subject: own plugin doesn't work fine with paths |
 |
|
Hi Everyone,
i'm working with smarty by first time and i need your help.
I created my own smarty plugin, this plugin only gets one param, with a path. Then, checks if there are any image (with .jpg extension) inside this path, and put all images found into another array.
Then, assign the second array into smarty, and i want it to use in a .tpl file, but when i do a foreach in tpl, the plugin works fine, but is checking a sibling folder, not the folder that set into a param when call the function.
I paste my code below to help you understand.
---- Smarty Plugin -----
-------------------------------------------------------------------------------
| Code: | function smarty_function_getImages($params, &$smarty){
if(!isset($params['directory'])) {
trigger_error("Error, path is needed.", E_USER_NOTICE);
return;
}else{
if(is_dir($params['directory'])){
$aux = scandir($params['directory']);
$aux2 = array();
for($i = 0; $i<sizeof($aux); $i++){
if(!is_dir($aux[$i])){
if(substr($aux[$i], -3) == "jpg"){
echo $aux[$i];
array_push($aux2, $aux[$i]);
}
}
}
$smarty->assign('rightItems',$aux2);
}else{
trigger_error("Invalid folder.", E_USER_NOTICE);
return "Invalid folder.";
}
}
return;
} |
-----------------------------------------------------------------------------------
---- .tpl file ----
-----------------------------------------------------------------------------------
| Code: | {foreach from=$rightItems item=foo}
{$foo}<br />
{/foreach}
|
-----------------------------------------------------------------------------------
Someone has had this problem?
I'm sure that will be a little mistake, but by the moment i don't found the solution
Thanks in advance |

I finally found the error...
another line was calling the same function with another path, the problem is that the line is commented with html tags <!-- and -->
smarty comments must be {* *}
well, this will not forget  |

Don't use for while iterating over an array.
Use foreach. It's faster.
Also there's no reason to &$smarty, as objects ALWAYS passed by reference. |
