functions dont exist (but they do)

[visualazza]

hi,

 

im getting the error

 

Fatal error: Call to undefined function notification() in C:\xampp\htdocs\xampp\index.php on line 21

 

after including the functions.php file i wrote. It does include it but the data isnt being recognised from it. If i copy/paste the notification() function into index.php it works.

 

Can someone tell me why so i can fix it?

We need to see relevant code.

[visualazza]

index.php

require("functions/functions.php");

 

functions.php

function notification()
{
$error = $_GET['error'];

if ($error != "")
{
switch($error)
{
case 0:
        $error =  "Unspecified Error";
        break;
    case 1:
        $error =  "i equals 1";
        break;
    case 2:
        $error =  "i equals 1";
        break;
}
echo("<div class='error'>$error</div>");
}
}

That doesn't really help. Can you post your entire index page up to the point where you're calling the function? There could also be a problem somewhere else in your functions.php file so post the full source to that please.

sorry but i cant post the index.php file due to the project being completly secret but other than requiring functions.php and calling notification() its all just design html.

 

The functions.php file is (at the moment) just what i posted before but in <?php ?>

[visualazza]

ok so after doing a few (many many) checks i have found that it is the fact i am using $_SERVER['HTTP_HOST'] in the require (sorry i forgot to put that in the first post)

 

Why is it stopping is from working?

i forgot to put that in the first post

 

If you are not posting (simple as copy/pasting) the actual code that exhibits the symptom, no one can help you with your actual problem.

 

$_SERVER['HTTP_HOST'] has absolutely nothing to do with forming a file system path to where your file might be located on the server.

[visualazza]

but thats the thing, i take it out and it all works as it should so

[visualazza]

ive made a separate couple of pages and the same thing occurs

 

temp.php

<?php
require("http://".$_SERVER['HTTP_HOST']."/testfunc.php");
test();
?>

 

testfunc.php

<?php
function test()
{
echo("The function works");
}
?>

You cannot include a file using a URL. You need to use a local file path!

 

Eg

require $_SERVER['DOCUMENT_ROOT'] . '/testfunc.php';

[visualazza]

using document_root is a problem

 

my localhost is fine with it but my server is weird and throughs errors saying it cannot find the file

[wildteen88]

Ok, omit that variable and do

require 'testfunc.php';

 

 

[visualazza]

again its a problem as i need to be able to access the file from another folder lower down

[wildteen88]

Can you post your sites file structure.. You can go higher up in your directory structure using ../

[visualazza]

root

  functions

    functions.php

  areas

    area1

      index.php (this calls header.php 2 levels higher)

  header.php (this calls function.php)

  index.php (this calls header.php from same folder)

You do realize that if you had continued with this problem in your first thread about it, you could probably have solved it by now.

 

Your $_SERVER['DOCUMENT_ROOT'] is apparently empty. Your web host can probably fix it by correcting the vhosts definition.

 

However, after your php script starts, $_SERVER['DOCUMENT_ROOT'] is just a variable that you could set yourself with the correct value for your actual document root and it would allow you to form absolute file system paths to where your include/require files are actually located.

[wildteen88]

To call header.php in areas/area1/index.php you'd use the following path

require '../../header.php';

 

In header.php you'd use the following path to call functions.php

require 'functions/functions.php';

 

To call header.php in the root index.php file you'd use the following file path.

require 'header.php';

[visualazza]

problem with that is that in area1, functions.php wont be found because the included header has functions/functions.php not ../../functions/functions.php

[wildteen88]

I just tested it and it worked. I went to site.com/areas/area1/ I asummed thats how you called index.php in areas/area1

[visualazza]

but i dont want to duplicate header.php or functions.php

 

header.php is in the root folder

functions.php is in functions folder 1 below root

[wildteen88]

I haven't duplicated those files.

 

I setup the file structure as you posted earlier

root

  functions

    functions.php

  areas

    area1

      index.php (this calls header.php 2 levels higher)

  header.php (this calls function.php)

  index.php (this calls header.php from same folder)

 

Download the attached zip. Extract to your root folder. Go site.com/visuallaza to test

thanks for your help, it works now.

 

I thought php got the contents of the required file like html does with css and other documents where is gets the contents and acts like that file is in the same folder as the one that is calling it.

 

Guess not

 

Thanks again for all your help
