Calling other function in the same controller?

Question

I\'ve this controller, and the function read($q) return error Call to undefined function sendRequest()

Answer 1

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

Answer 2

Yes. Problem is in wrong notation. Use:

$this->sendRequest($uri)

Instead. Or

self::staticMethod()

for static methods. Also read this for getting idea of OOP - http://www.php.net/manual/en/language.oop5.basic.php
