How to write a FaceBook Application in 10 minutes

From: http://gathadams.com/2007/06/18/how-to-write-a-facebook-application-in-10-minutes/

Writing F8 apps is where it’s at right now. Everybody knows it. The userbase is huge and now we have a (free) API to. Everything is good….but the documentation.

I spent a day writing my Sudoku Facebook application yesterday. I already had the sudoku javascript widget ready to go – the time was spent wading through pages of documentation and downloading toolkits that (as it turns out) I didn’t need.

dotProject error: query failed about username

EDIT: Fixed in stable_2 as of revision 5798.

When users try to reply to a forum post the system throws an SQL error.

It is happening because a user_id is not being delimited with quotes.

Here is the message we see…

Quote:

ERROR: /home/mysite/public_html/zzzproj/classes/query.class.php(623): query failed(SELECT contact_first_name, contact_last_name FROM ( `users` ) LEFT JOIN `contacts` AS con ON contact_id = user_contact WHERE user_username LIKE ‘tofjohn’ OR user_id = tofjohn) – error was: Unknown column ‘tofjohn’ in ‘where clause’

My Analysis: WHERE user_username LIKE ‘tofjohn’ OR user_id = tofjohn) – error was: Unknown column ‘tofjohn’ in ‘where clause’
should have parameter for user_id quoted as in… OR user_id = ‘tofjohn’)

I tried to find a fix by looking at query.class.php and found the make_where_clause function, but looks like the problem comes somewhere before that. Will keep looking thru more source…

Current versions of system are in my sig.

 

fix:

/* $q->addWhere(“user_username LIKE ‘$user’ OR user_id = ” . $user); */
$q->addWhere(‘user_username LIKE \”.$user.”‘”);
