Cannot access protected property JException::$code

问题

Fatal error: Cannot access protected property JException::$code in /.../templates/abrax/error.php on line 14

Lines 14-17:

if (($this->error->code) == '404') {
header('Location: http://www.example.com/404');
exit;
}

回答1:

Use getters, you can't access property directly because it's visibility is not public

Like

if (($this->error->getCode()) == '404') {
...

回答2:

try this

if ($this->_error->get('code') == '404') {
header('Location: http://www.example.com/404');
exit;
}
