A nifty little trick to prevent a lot of trouble.Every single programmer must have had this problem at least once. You have unexpected behaviour and can't find where the problem occurs. Finally, after a lot of searching, you find the problem in an if-condition. Instead of using ==, you used =. Stupid! Sean Coates posts about a nifty little trick to prevent this. Instead of testing the value of a variable against a constant, do it the other way round. So, instead of .bq if($loggedIn == TRUE) you do it the other way round: .bq if(TRUE == $loggedIn) Advantages: if you accidentally type a single '=', your code breaks, since you can't assign a value to a constant using this notation. Also, you won't accidentally overwrite a possible essential variable, allowing easy cracking of your site/cms/whatever.
