What code did you try to use to hide the form? I can't see it looking quickly.


If you are using JQuery you should be able to easily hide the form with .hide(), referencing the form by it's id attribute:

Since your submitting the form to itself, why not just use an if-then statement based on available post variables? Shouldn't be too hard to implement:


Something simple like this should do the trick:

if (!isset($_POST['com_firstname']){
 //show form 
} else {
//hide form

Also, I'm not sure you actually need to sanitize the data. I remember reading that certain methods used by wpdb like $wpdb->insert, etc are sanitized automatically by the $wpdb class (someone who's a bit more familiar with the wpdb class in wordpress, feel free to correct me if I'm wrong, but I think that's the case)
