I'm screwed to your code of arrays.... your echoing an empty set of arrays??? and yet arrays cannot echoed.... use print() or print_r() to echo the elements of the arrays. and check if whether it runs an error.

OMG. do not use PHP for that.... you'll have to use JAVASCRIPT

basically in javascipt is where validations forms started and it's good for server computing

can u please correct my code..im new to php
and tried these code to my best..to ceorrect..

im getting lots of errors..

and how to validate the files upload??
