Question

I am following some examples in the PRO PHP AND JQUERY book, but for some reason the examples doesn’t work. Even the examples that I downloaded from the books site doesn’t work. Not sure whats wrong, because I have done exactly as in the book..

/public/Index.php

include_once '../sys/core/init.inc.php';
$cal = new Calendar($dbo, "2010-01-01 12:00:00"); //ERROR Class 'Calendar' not found

/sys/core/init.inc.php

    function __autoload($class)
    {
        $filename = "../sys/class/class." . $class . ".inc.php";
        if ( file_exists($filename) )
        {
            include_once $filename;
        }
    }

/sys/class/class.calendar.inc.php

class Calendar extends DB_Connect
{
    private $_useDate;
    private $_m;
    private $_y;
    private $_daysInMonth;
    private $_startDay;

    /**
     * Create a database containg relevant info
     *
     * @param object $dbo a database object
     * @param string $useDate the date to build calender
     */

    public function __construct($dbo=NULL, $useDate=NULL)
    {
        /*
         * Call the parent constructor to check db object 
         */
        parent::__construct($dbo); 
    }


}

This is very annoying since every chapter in the books builds on this simple foundation. My guess is that __autoload() is the problem, but I have no idea..

Answer 1

The filepaths do not point to the right spots.

A better idea would be something like this in Index.php…

define('DOCROOT', dirname(__FILE__));

…and then modify your __autoload() like so…

function __autoload($class)
{
    $filename = DOCROOT . "/sys/class/class." . strtolower($class) . ".inc.php";
    if ( file_exists($filename) )
    {
        include_once $filename;
    }
}

You should strotlower() the filename before including it, as your class is Calendar but your filename has calendar.
