为什么我会收到一个聪明的通知：“试图在第348行的…\\ sysplugins \\ smarty_internal_templatecompilerbase.php中获取非对象的属性”？

Question

I create my $smarty object according to the Smarty manual and I get the following notice:

Notice: Trying to get property of non-object in ...\smarty-3.1.32\libs\sysplugins\smarty_internal_templatecompilerbase.php on line 348

What does this mean and how can I avoid it?

Answer 1

This error message appears when you extend the Smarty class but from the new constructor you don't call the parent constructor. Do something like this in your child class:

class SmartyExtend extends Smarty {
    function __construct() {
        parent::__construct();  // this is the line that was missing
        $this->setTemplateDir(...);
        $this->setCompileDir(...);
    }
}
