You might want to do something like this...

 

if (isset($_POST['submit']))
{ 
   // get form data
   // set a boolean "$no_errors" to true
   // check for errors. If you find any errors, set $no_errors to false
   // only insert data into the database if $no_errors == true
}

 

This would stop the data from inserting if you have errors in the input.
