[UPHPU] Setting a variable with an if statement?

[Randy Moller]

if your description field is set to not null, then it should accept an 
empty string (mysql?), like this:

$description = !empty($_POST['description']) ? $_POST['description'] : '';

Otherwise, if you "must" have a value of a length > 0, then do something 
like this:

$description = !empty($_POST['description']) ? $_POST['description'] : 
'blank';

The empty function accounts for all boolean false and null values, like 
0,null,false, or "".
The construct () ? : ; is the ternary operator, and is very handy for 
writing concise code
when your conditional is an "if/else".

Hope that helps!
