我的index.php包含......
<form class="form-signin" action="submit.php" method="post">
<input class="form-control" type="text" id="name" name="name" required="" placeholder="Name" autofocus="">
<input class="form-control" type="text" id="institution" name="institution" required="0" placeholder="Institution" autofocus="">
<input class="form-control"type="email" id="email" placeholder="Email Address" autofocus="" />
但是当我使用...提交表单时
$name = $_POST['name'];
$institution = $_POST['institution'];
$email = $_POST['email'];
$query = "INSERT INTO participants (name,institution,id) VALUES ('".$name."','".$institution."','".$email."')";
我收到了错误......
