[SOLVED] Help needed ASAP!

hass1980 · April 30, 2009

Hi,

Im getting two errors coming from the admin site of the website. Products.php and catergories.php

Fatal error: Call to undefined function products() in C:\wamp\www\cart\admin\products.php on line 21

Fatal error: Call to undefined function categories() in C:\wamp\www\cart\admin\categories.php on line 23

I have also added the site as a zip file if you need the additional files!

Categories.php

<?php
// Include MySQL class
require_once('../inc/mysql.class.php');
// Include database connection
require_once('../inc/global.inc.php');
// Include functions
require_once('inc/functions.inc.php');
// Include functions
require_once('inc/category.inc.php');
// Include functions
require_once('inc/product.inc.php');
// Start the session
session_start();

if(!isset($_SESSION['AdminID']))
{
     return header("location: myaccount.php?action=login");
     exit;
}

$array['categories'] = 'selected';
siteHeader($array);
echo categories();
siteFooter();
?>

products.php

<?php
// Include MySQL class
require_once('../inc/mysql.class.php');
// Include database connection
require_once('../inc/global.inc.php');
// Include functions
require_once('inc/functions.inc.php');
// Include functions
require_once('inc/product.inc.php');
// Start the session
session_start();

if(!isset($_SESSION['AdminID']))
{
     return header("location: myaccount.php?action=login");
     exit;
}

$array['products'] = 'selected';
siteHeader($array);
echo products();
siteFooter();
?>

The error's mean that nor products() nor categories() is defined when you are calling them make sure you include the required files

hass1980 · April 30, 2009

right, but im assured these are correct and was told to just unzip and connect to the database and it will work. Its working on there computer. So how do i change this? im a novice!

Try replacing

// Include functions
require_once('inc/functions.inc.php');
// Include functions
require_once('inc/category.inc.php')
// Include functions
require_once('inc/product.inc.php');

with:

// Include functions
require_once('admin/inc/functions.inc.php');
// Include functions
require_once('admin/inc/category.inc.php');
// Include functions
require_once('admin/inc/product.inc.php');

no that didnt work

mrMarcus · April 30, 2009

from the directory Categories.php and products.php are in, navigate to the 'inc' folder, open function.inc.php and products.inc.php and locate the functions in question .. make sure they're there, don't just assume it 'cause somebody told you so.
