Calling a user made functionfunction

I have alot of db queries and alot of them happen regulary. So I decided to create a class with those functions. Since I never really created my functions or class I decided to go with one of the easiest of functions just to test out if i am doing it right. As it turns out I am doing it wrong. The page is giving me

Here is the code for botht he class file and the page tryng to czll the function



That was the page callign the function and here is the other file

Functions contained within a class are actually called methods. In order to access these methods you have to create a new "instance" of the class and store it in a variable. Then to access a method you use the "->" operator. In your case the code would look something like :



I hope that helps out!

hmm, to use functions you dont need to use classes!

just use:

I now got that working but I have another question. In my file I have a number of functions now. Can I get one function to call another function? If I can, can I call function 2 into function 1. For instance:

yes, that code would work!

in the first function I originally had it include a seperate file and it worked fine but i added the contents of that file to my function file as it's own function but it is not working and i am not sure why it isn't.

Here are the two functions


Any ideas as to what I am doing wrong?

what error messages are you getting, and which line??

On a hunch... try calling your second function like so:

$this->newsType();

See if that works...

After a second look i know what the problem is now!

firstly frankie, $this->newsType(); is used in a class. You would use this when your making a refrence to a function, which is called inside another class funcion.

CHornJr, there is a few problems with your code.

Firstly a function cant use variables that are not declaired inside the same function. which means



this would result in an error, cos the var $var has not been defined in the function, there are a couple of work arounds here, make the $var a global with

global $var;

inside the function, before the $var is called, or pass the $var as a argument

function Test ($var) {...

and when you call the function

Test($var);

so in your case you would need to declair the $news as a global

your function newstype() actually returns a value, meaning, if you where to echo the function, you would echo a value. you need to assign the function to a $variable

$var = newstype();

Ok I am little confused here cause I thought I tried what you said but apparently I didn't do it correctly.

In function viewnewshome I have after I declare $news

you will need to declair the global in the newstype function

function NewsType() {

global $news;

....


then the next change is where you have

newstype();

in the first function. Calling this function without assigning it to a var, or string doesnt actually do anything, because the variable

$newstype

has been declaired inside that function, however you return it, so if you change the line

newstype();


$newstype = newstype();

it will cause your function to work.

if you make those 2 changes your code should then work

Ok it is jumping straight to the else statmement in the second function

try checking your database, also please post what code you have so far
