 Posted: Fri Jul 06, 2012 6:23 pm Post subject: First view/request generates unlink error |
 |
|
Hi All,
I have a big problem with my app and smarty, but i will shorten it to example below.
My configuration is:
- smarty v 3.1.10
- xamp v 1.7.3
- php v 5.3.1
- windows xp with sp3
Like in subject when I want to display a template then on first request I have an error:
| Quote: | Code:2, Message:unlink(c:\xampp\htdocs\ajax_smarty\templates_c\3b16de6736e2c828b29066610d68a9bc8ae0920e.file.abc.tpl.php) [function.unlink]: No such file or directory, File:C:\xampp\php\smarty\libs\sysplugins\smarty_internal_write_file.php, Line No:57"
|
And the second request is without error.
All the above also applies to Ajax POST request.
My code looks like this:
Main file: index.php
| Code: |
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<HTML>
<HEAD>
<TITLE>Ajax Smarty Test</TITLE>
<script TYPE="text/javascript" language="JavaScript" src="http://localhost/ajax_smarty/ajax.js"></script>
</HEAD>
<BODY LEFTMARGIN="0" RIGHTMARGIN="0" TOPMARGIN="0" BOTTOMMARGIN="0">
<?PHP
try
{
require_once('Smarty.class.php'); // load Smarty library
$smarty = new Smarty();
$smarty->template_dir = 'views/';
$smarty->config_dir = 'config/';
$smarty->cache_dir = 'cache/';
$smarty->compile_dir = 'c:\\xampp\\htdocs\\ajax_smarty\\templates_c\\';
$smarty->assign('empty', 'nothing');
var_dump($_POST);
if (isset($_POST['a']) && $_POST['a']==1)
{
echo "fetch<br>";
$smarty->fetch('abc.tpl');
}
else
{
echo "display<br>";
$smarty->display('abc.tpl');
}
$aError = error_get_last();
if(!is_null($aError))
throw new Exception('Error 404 for AJAX action:'.$_inducedAction.'; Code:'.$aError['type'].', Message:'.$aError['message'].', File:'.$aError['file'].', Line No:'.$aError['line']);
unset($aError);
}
catch (Exception $e)
{
echo "\nERROR:<br><pre>";
var_dump($e);
echo "</pre>";
}
?>
<INPUT TYPE="button" ID="submit_form" NAME="submit_form" VALUE="SEND" onclick="AjaxPostRequest('http://localhost/ajax_smarty/index.php', 'a=1', 'alert');">
<BODY>
|
Template: abc.tpl
| Code: |
test ajax_smarty: template abc<br>
variable = {$empty}
|
Sorry for my English, but it's not my mother tongue.
Best for All,
and thanks in advance for any try to help,
Gzom |

Hi,
Thanks rodneyrehm for reply.
I'm reading those articles, but in meanwhile could you explain me why smarty deliberately generates warnings or notices?
Best,

Hm...
Unfortunately in my case there should not be "Race Conditions".
Only I run the sample script, and only in one request/view. |

Ok,
Thanks rodneyrehm for muteExpectedErrors() method (which solved my problem), and at least partial explanation what is going on.
Again Thanks Very Much.
Best,
Gzom
P.S. If you could explain why I have this errors even when I should not have race conditions, would be more than great. |

It doesn't matter if YOU are prone to race conditions RIGHT NOW. Smarty itself does everything it can to prevent them. always. regardless of your use-case. You don't have to worry about it.
