簡單實用的Bootstrap+PHP表單驗證實例，非常適合初學者及js不熟悉者，還有ajax遠程驗證

js驗證表單

61                 // Use Ajax to submit form data 
62                 $.post($form.attr(‘action‘), $form.serialize(), function(result) { 
63                     console.log(result); 
64                 }, ‘json‘); 
65             });

PHP遠程驗證用戶名

1 $userName = $_POST[‘username‘]; 
2  
3 echo json_encode(array( 
4     ‘message‘ => sprintf(‘Welcome %s‘, $userName), 
5 ));
