Opencart 2.0从admin或前端获取配置值也是Permission

Question

Is it possible in opencart 2.0 to get the value from the settings. For example as it was in previous opencart versions I could store value to database via settings, thus I did not need any model file to write to database and then from anywhere I could get the value by:

$this->config->get('key_that_you_need');

... Now this still works but only when in controller. What I need is to get the value even when I'm in template file (*.tpl)

When I want to use this in *.tpl file I get this error:

Notice: Undefined property: Loader::$config

same situation applies for permissions... now you can't use this example from template:

<?php if($this->user->hasPermission('access','catalog/attribute')) { ?>

...however it is still functional in controller file

Does anyone know if it is possible or some workaround ?

Answer 1

You shouldn't be using it in your template in the first place - You should be setting the data for the in your controller and passing that to the template. However You can do this pretty easily. Firstly, you need to bring the $config variable into the template and then call it directly, not use $this

<?php
global $config;
$somevar = $config->get('key_that_you_need');
?>

Not tested but should still work just fine
