Using $this when not in object context in: php error

Question

I have solved this problem, I just need to know what to do. I get the above error because I just realised that the class is being run as class::function($values) instead of class->function($values).

Does anyone know how to convert this function to instantiate the class then run the function with values?

private function _load($values=null) {

    define('LOADED_CONTROLLER', $this->controller);
    define('LOADED_FUNCTION', $this->function);

    $function = $this->function;

    $controller = new $this->controller;
    ($values == null) ? $controller->$function() : call_user_func_array(array($this->controller, $function), $values);
}

What exactly are you asking here? You say you know what the problem is, so why are you still trying to get it to work using $this? You can't use $this in a static context. — ryeguy

You already instantiate the class:

$controller = new $this->controller;

Just use your $controller also in call_user_func_array:

($values == null) ? $controller->$function() : call_user_func_array(array($controller, $function), $values);

In your code you try to call a static method on the class if $value != null. That of course will result in an error if you use $this in this method.

Sorry I don't understand. As I don't know the number of parameters I am using call_user_func_array. However when I do this I cannot use $this in my controller functions. Is there an alternative function?

@JasonS: Of course you can do. But currently you are passing the class array($this->controller, $function) instead of the object array($controller, $funtion) to the function. That is where your error is.

Ah ofcourse, I couldn't work out what had been changed. Thanks so much!
