Question about variable scope, object and $html

2007-05-23 Thread Ming 

Hi,

I am new to Cake and I have a question.

For the file below (email.php), I do not understand where does the
render in
$this-controller-render($this-thtml) come from.

$controller ($this-controller) is a variable whose domain is limited
to this class. But it seems $this-controller is an object and it has
a render function

I searched the entire project and there are 3 render functions:

The 1st  is in app/controllers/components/output.php,
the 2nd is in cake/libs/view/view.php
the 3rd is in cake/libs/controller/controller.php

For this class (EmailComponent), which render function does it really
call? Why?

The confusing part for me, why $this-controller is an object instead
of a variable? I am using two different PHP IDE, after entering $this-
controller-, there is no code hint (if entering $this-, code hints
will popup controller, for example).

Additionally, I got to know the $html helper from cake's online
tutorial. But where is $html declared? I cannot find it.

Thanks,

Re: Question about variable scope, object and $html

By the way, I tried to get help from capk's online API. But cake's API
interface is pretty different with those of Java, Pear, or CPAN.
Sounds need some time to get familiar with it.

Re: Question about variable scope, object and $html

Hey John,

This script is from an app built on top of cakephp, and to maintain
this app is part of my new job. There are 557 files totally in app/
models, app/controllers, and app/views, and I want to go through all
over them so that I can work on the app.

Thanks,

I highly suggest you read the CakePHP manual before you even attempt
to figure this out.  From your comments I take it that you do not have
a lot of experience with MVC frameworks built in PHP.  If you did, a
lot of the questions you are asking would be easier to answer.

Part of the magic of using a framework is *not* knowing what  
everything does. Not many of us walk through Cake's source, not  
because we don't care, but because we really don't need to.

Are you tracking down a bug or something?

Yes, this app has many bugs. So far I have found nearly 100 bugs. I am
using both Zend studio and phpedit to debug it. I have quite a few
java and perl experience, but do not have too much php experience.

Thanks,

Re: Question about variable scope, object and $html

2007-05-23 Thread Ming 

I read it, and I did the online tutorial line by line. But I still do
not quite understand. Back to my question, is $this-controller an
object? But $controller is a variable defined in this class.Or maybe
$controller is a variable passed by reference that points to an
object?

For the $html (introduced in the blog tutorial), as I never declare
it. Is it a global variable (global object?)? If yes, where is it
declared?

Many thanks,
