Posted: Tue Mar 23, 2004 9:10 pm
hai. i am new in php programming. i hope anyone can help me or give me a few resources.
here is the problem i faced :
i have 2 variable $a and $b . these are from 2 different text box. i wan to compare these 2 values. one value will be null and the other must not be and vice versa. the non null value will be passed to another variable, $c. and i wan to check again if the $c value is not in database to avoid duplicate record.
thanks !
