Question

Im currently using codeigniter 2 with ci-Smarty. Just been trying to add a smarty output filter but not having much luck. Its as if the function cannot be found or something?

I am using a plugin as the output filter function and have the following code:

LOCATION: /libraries/Smarty.php

// Set email output filter
$this->loadFilter('output', 'protect_email');

LOCATION: /third_party/Smarty/plugins/function.protect_email.php

function smarty_function_protect_email($tpl_output, Smarty_Internal_Template $template)
{
    $tpl_output =
       preg_replace('!(\S+)@([a-zA-Z0-9\.\-]+\.([a-zA-Z]{2,3}|[0-9]{1,3}))!',
                    '$1%40$2', $tpl_output);
    return $tpl_output;
}

The above seems to throw the following smarty error:

Fatal error: Uncaught exception ‘SmartyException’ with message
‘outputfilter “protect_email” not callable’ in

Sorry about it being so long! Just thought seeing the whole error may help.

Thanks a lot for reading and hope someone can help.

–>EDIT
Also just tried to explicitly set the plugins directory location using:

$this->setPluginsDir(config_item('plugin_directory'));

The echoed out the location which is correct but still get the same problem 🙁

Answer 1

Okay that was a silly mistake.

For anyone else who has the same problem I was just looking through and realised the plugin should not be referred to as a regular function. For example it should have been called:

outputfilter.protect_email.php

Also make the same amends with the function name as well so in my case it should be called:

smarty_outputfilter_protect_email

This worked great for me.
