Hi there,

Well i have a registration page with the following two tables, the “About you” table and the “Invoice” table, and then underneath i have a checkbox. In the “About you” table you fill in your details, what i need to know is, how do i make it possible that if you click the checkbox, then the same details that is displayed in the “About you” table is displayed in the “Invoice” table. Thanks in advance. ![8)]()

Heres the code:

[php]\<?  
// now we insert it into the database  
$insert = “INSERT INTO users (user\_company, user\_address, user\_title, user\_firstname, user\_lastname, user\_job, user\_tel, user\_fax, user\_email, user\_inv\_title, user\_inv\_firstname, user\_inv\_lastname, user\_inv\_job, user\_inv\_tel, user\_inv\_fax, user\_inv\_email, user\_inv\_address)  
VALUES (’”.$\_POST[‘user\_company’]."’, ‘".$\_POST[‘user\_address’]."’, ‘".$\_POST[‘user\_title’]."’, ‘".$\_POST[‘user\_firstname’]."’, ‘".$\_POST[‘user\_lastname’]."’, ‘".$\_POST[‘user\_job’]."’, ‘".$\_POST[‘user\_tel’]."’, ‘".$\_POST[‘user\_fax’]."’, ‘".$\_POST[‘user\_email’]."’, ‘".$\_POST[‘user\_inv\_title’]."’, ‘".$\_POST[‘user\_inv\_firstname’]."’, ‘".$\_POST[‘user\_inv\_lastname’]."’, ‘".$\_POST[‘user\_inv\_job’]."’, ‘".$\_POST[‘user\_inv\_tel’]."’, ‘".$\_POST[‘user\_inv\_fax’]."’, ‘".$\_POST[‘user\_inv\_email’]."’, ‘".$\_POST[‘user\_inv\_address’]."’)";  
$add\_member = mysql\_query($insert);  
?\>

If I get it right, it’s a control flow issue:

`if (checkbox_checked) {
  showDataInInvoiceTable();
} else {
  showDataInAboutYouTable();
}`

In pseudocode 😉

Well, the code is pretty staightforward. Google a bit for PHP control flow structures, or try the PHP manual to get up-to-speed on them (coz your questions tell me you aren’t).

But now I understand what you mean! You can do that through a page refresh through PHP, or on-the-fly through Javascript (or perhaps AJAX, but I know nothing about that).
