Validation Callback function not working

[eluser]jblack199[/eluser]
i've never been a fan of var_dump try:

Code:

echo "<pre>";
print_r($verifyusername);
echo "</pre>";

I think it puts it into an easier to read fashion... and you've echo'd out $verifyusername->num_rows() and checked to see what it returns

but try changing $verifyusername->num_rows to $verifyusername->count_all('tbregister') and see if that fixes it...
