Off Topic PHP question regarding classes and referencing.

Hi all,

I know this is probably not the best place to post this message and although I have searched I have been unsuccessful in finding an answer.

I’ve been coding a small program and using modX as my CMS core. My problem is how to create a class that use to other files containing classes and reference them accordingly.

For instance, my program contains the following files:

ncr.php
data.php
file.php

my main class is called through a snippet:



I then make a connection to the other two files using require_once and $this->db and $this->fl.

My problem is when adding functions inside the data class I dont seem to be able to call functions contained within the file class.

I find my code works but is rather embarassing to look over. Am I missing something fundamental in trying to call a function in this manor?

I’m thinking I should be able to call it from the main ncr class downward but alas it just aint so.

I’m lost if anyone could help I would really appreciate it.

Thanks,

BBloke

How are you instantiating $complaint->db and $complaint->fl ? If you can include more of the code you’ve used to establish these references, perhaps we can provide some advice.

Thanks OpenGeek,

In the main ncr class I have:

Ok, I think the problem here is trying to use $this in the constructor when instantiating the file class. Try creating a local var in the constructor to represent the $db var since $this is really not valid as an accessor until after the constructor has completed:

Thanks for another quick reply. I’m thinking I’ve either described it wrong or I’m not just getting this at all.

I can make it all work great if I create another object in the data class to the file class but I don’t want to do that. At the moment, to me it looks like:



I can call any function from either file or data whilst in the ncr class but I can’t call a function from data that is contained within file unless I do the following:
