Function Calling

CMellor · 10-05-2007, 09:35 PM

Hey,

Here's a folder structure I have:

configs
- functions.php
- ajax_functions.php

In functions.php I have a function called getUser. I want to use that function in ajax_functions.php, but when I call it, I get the "Function does not exist" message. I used include to include the functions.php file into ajax_functions.php but that gave errors saying it couldn't open such folders as libs/Smarty.class.php.

How can I call getUser in the ajax_functions.php when the function is wrote in functions.php I hope I don't have to have the function in both pages, I was hoping to just have it in the one.

Hope you understand... thanks for the help if any.

It all depends on the project structure. Where are you including functions.php and ajax_functions.php from? For example, consider your full setup was:

my_project
> config
> index.php

If we wanted to include both files inside index.php, we could simply use the following statements:

PHP Code:


			
require_once('./config/functions.php');
require_once('./config/ajax_functions.php');

That's all there really is to it. You just need to remember how PHP works, we're including the files in the index.php file, therefor, in reality we're actually pulling the data out of those files and essentially "pasting" it into the index.php file.

configs
-- functions.php
-- ajax_functions.php
ucpanel.php

In ucpanel.php I include the functions.php file. I use the request method in PrototypeJS to call AJAX, and it grabs the ajax_functions.php from the form action.

Ah right, I see. In that situation you will need to include functions.php inside the ajax_functions.php file. Don't specify any path, just the filename, such as:

require_once('functions.php');

The problem I get when doing that is, in functions.php, I have another include:

Code:

include('libs/Smarty.class.php');
$smarty = new Smarty;

I've had it where it doesn't include the class file, and also had it say "Smarty class does not exist" which it clearly does...

Meh, I just gave in and copy/pasted the function into the ajax_functions.php file as well as in the functions.php file.
