Cannot test if a field is empty or not

[eluser]toopay[/eluser]

Code:

return (count($result) >0 ? $result[0] :NULL);

that means, if the result more than 0, the function return first row matched

Code:

$result[0]

if not, it returns NULL. For an array result, you can just simply change

Code:

$result[0]

to

Code:

$result

at the end of your model function, and write the rest proper code at your controller to handle that array.
