Very good advice PFMaBiSmAd. I was trying to be very straightforward, but I probably should have mentioned this. Thanks, -Seven_Rings

The only thing you are doing wrong is the isset. Syntax is isset($var). This should be a working version of your code: <?php if(isset($_GET['page'])) { $page = $_GET['page'].'.txt'; include $page; } else { include 'default.txt'; } ?> Enjoy, -Seven_Rings

You where right. The var_dump after: $database = new PDOMySQL(); was great... but before I called start_session it was NULL. I have no idea how this could be happening. I like the extending ideas, but would it be better for me to use a singleton, or to make Session extend PDOMySQL? Asking expert advice on which is better in my case, since you guys probably have a decent idea of what my script is. *Mostly a login system right now* Thanks again, -Seven_Rings

Well, instantiating the class inside the function DID work. But I am including database.inc before I am trying to call it. I am including database.inc and session.inc on the same page. And I am not resetting $database anywhere. Database is included first. If instantiating the class inside the function isn't the way to do it, than what is? I have done a bit of reading on OOP, but if you know the answer, I would certainly like to hear it. Thanks, You guys are great. -Seven_Rings

I posted the code that was calling add_active_guest... I'll post it again with the rest of the function (which is also inside of a different class). <?php class Session { // Class constructor and other functions... function start_session() { global $database; session_start(); $this->logged_in = $this->check_login(); $this->url = $_SESSION['url'] = $_SERVER['PHP_SELF']; $this->ip = $_SERVER['REMOTE_ADDR']; if(!$this->logged_in) { $this->username = $_SESSION['username'] = GUEST_NAME; $this->userlevel = GUEST_LEVEL; if(TRACK_GUESTS) { $database->add_active_guest($this->ip, $this->url, $this->time); } } else { if(TRACK_USERS) { $database->add_active_user($this->username, $this->url, $this->time); } } /* Remove inactive visitors from database */ $database->remove_inactive_users(); $database->remove_inactive_guests(); } }; $session = new Session(); ?> database.inc is included in the same source as the code I posted, so $database should be an instance of the PDOMySQL class. And I am globalizing $database because I am calling it from within a function. I have been coding for quite a while now, and I am pretty sure that is the correct thing to do. Hopefully between this and the last post, the answer will be obvious. Thanks for your time, -Seven_Rings

@premiso: I made the var global because it was inside of a function... had nothing to do with OOP. Anyways, I ended up taking your advice, which was actually the way I used to have it setup. Not sure why I changed, or that I want to remind myself. It works for now. Anyways, there is a new problem now, and since it's of the same type, I figured I would post it here. database.inc <?php require_once 'constants.inc'; // Includes the constants here. They are all valid. error_reporting(E_ALL); // Does about no good in error reporting. class PDOMySQL { // Various functions here including the class constructor... /* This is the function that is having a problem. */ function add_active_guest($ip, $url, $time) { /* If we aren't tracking visitors, stop here and return. Else continue. */ if(!TRACK_GUESTS) return; /* If we are tracking guests, add the active guest into the database. */ $stmt = "REPLACE INTO ".TABLE_ACTIVE_GUESTS." VALUES (?, ?, ?)"; $vars = array($ip,$url,$time); $sth = $this->query($stmt,$vars); /* And lastly, we will update the number of active guests since we just changed it. */ $this->calc_num_active_guests(); } /* Fixed this function already, here for refrence. */ function query($stmt,$vals) { $sth = $this->con->prepare($stmt); if(!$vals) { $sth->execute(); } else { $sth->execute($vals); } return $sth; } }; $database = new PDOMySQL(); ?> And the code that is calling it... session.inc if(TRACK_GUESTS) { $database->add_active_guest($this->ip, $this->url, $this->time); } database.inc is properly included and all. The error is as follows... Fatal error: Call to a member function add_active_guest() on a non-object in C:\wamp\www\session.inc OOP sometimes just doesn't feel worth the trouble. But hopefully someone can shed some light on what I am missing here... Thanks! -Seven_Rings

Just went through the code again... this one is killing me. -Seven_Rings

Oops... I forgot to post "the problem". I cant find a way to edit the first post. I was punished on here before for double posting, but since I just read the rules, and they say nothing about it, I do not expect to be punished. The error I am getting is the following: Fatal error: Call to a member function prepare() on a non-object in C:\wamp\www\index.php Thanks again, -Seven_Rings EDIT: This class is full of database functions, this *is* my database script. It's not just a PDOMySQL class.

Hey. I have been having this problem with a lot of objects... for a very long time. I probably just don't understand the frustrating method of error reporting for objects. Here is the code that isn't working. <?php require_once 'constants.inc'; // Includes the constants here. They are all valid. error_reporting(E_ALL); // Does about no good in error reporting. $con = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASSWORD); // Looks right to me. class PDOMySQL { // Various functions here including the class constructor... function query($stmt,$vals) { global $con; $sth = $con->prepare($stmt); if(!$vals) { $sth->execute(); } else { $sth->execute($vals); } return $sth; } }; $database = new PDOMySQL(); ?> Any help you can give me at all is greatly appreciated. Thanks, -Seven_Rings

I'm not able to get anywhere with this. I cant seem to implement the JavaScript "edit_in_place" Here is what I am working on... http://www.thesevenrings.com/skillcomp/index.php I need to be able to edit the fields in the table with either "edit_in_place" or PHP (badbad's example) Can anyone help me? *It would take a lot of changing stuff to post my actual code* Thanks, -Seven_Rings

thebadbad, Seeing as how I don't really want to use JavaScript in this particular project, your post is very helpful. I think I could edit it to work, and if not, I have always got JavaScript Thanks for the help everyone, -Seven_Rings

Yea, I think I found what I need. It may take some time to adopt only one of the examples, but I think I can use a watered down version of http://tool-man.org/examples/edit-in-place.html Thanks for the help, I may be coming back here for more help. I really appreciate you guys -Seven_Rings

But it needs to look like a normal table cell until I give the command to edit it, at which time it would change to an editable field, and when submitted (user presses button, clicks off), an update query is run. -Seven_Rings

Theoretically, they are coming from a database. The goal would be to update the database. Thanks, -Seven_Rings

Thanks, I really appreciate it. *Not quite solved yet*, -Seven_Rings
