Answer:
```
if ($this->cismarty->get_template_vars('test') === null) {
$this->cismarty->assign('test', 'Default value');
}
``` | **Smarty 2**
```
if ($smarty->get_template_vars('foo') === null)
{
$smarty->assign('foo', 'some value');
}
```
**Smarty 3**
```
if ($smarty->getTemplateVars('foo') === null)
{
$smarty->assign('foo', 'some value');
}
```
Note that for **Smarty 3**, you will have to use `$smarty->getTemplateVars` instead. |
