[FX.php List] Checkbox

[Derrick Fogle]

The foreach() loop operating on the value list is working correctly,  
right? You get one checkbox for each value in the value list?

I've never seen the selected/checked value placed in quotes before;  
what happens if you do the selected output without being in quotes  
(but make sure there's a space after the closing quote for the value  
parameter)?

Also, I would drop the third argument from the in_array() function;  
it only serves to make the comparison a strict "type-alike" match.  
Remember, too, that everything is case sensitive, although the code  
looks like it should be comparing like-cased values.

The only other thing I can think of is the difference in the way the  
value list and the actual values are formatted. The value list has  
different separators than the actual field with the checked values, I  
think. The field with checked values should have each value separated  
by a return (\r), while the value list itself is an actual array, not  
a single field with some arbitrary separation character.

OK, my brain is empty now. Sorry I can't be more specific with my  
suggestions, but I hope this at least helps the debugging process.
