这是我的 save_reg 页面

    {
        $str = @trim($str);
        if(get_magic_quotes_gpc())
            {
            $str = stripslashes($str);
            }
        return mysql_real_escape_string($str);
    }
//Sanitize the POST values
$fname = clean($_POST['fname']);
$lname = clean($_POST['lname']);
$mname = clean($_POST['mname']);
$email = clean($_POST['email']);
$gender = clean($_POST['gender']);
$status = 'pending';
$bday = clean($_POST['month']).'/'.clean($_POST['day']).'/'.clean($_POST['year']);
$level = clean($_POST['level']);
$paymode = clean($_POST['paymode']);
$fincome = clean($_POST['fincome']);
$moname = clean($_POST['moname']);
$moccu = clean($_POST['moccu']);

$sec='none';
$ppic='images/profic.png';
$add = clean($_POST['address']);
$age = clean($_POST['age']);
$religiom = clean($_POST['religiom']);
$syear = clean($_POST['syear']);
$result = mysql_query("SELECT * FROM tuetion WHERE level='$level'");
    while($row = mysql_fetch_array($result))
        {
        if ($paymode=='Full Payment'){
        $payables=($row['payable']-($row['payable']*.05));
        }
        else if ($paymode=='Installment'){
        $payables=$row['payable'];
        }
        }
mysql_query("INSERT INTO prereg (fname, lname, mname, level, gender, paymentmode, payable, mother, m_occupation, father, f_occopation, family_income, section, status, email, bday, address, age, religion, ppic, schoolyear)

header("location: pre_reg.php");
?>

它可以保存数据，但甚至可以在插入之前保存我希望它验证的空白

在你的表格上写一个名字：

<form action="save_pre_reg.php" method="post" onsubmit="return validateForm()" name="registrationform">

发送前验证表单：

function validateForm()
{
  if (document.registrationform.fname == '') {
      alert('Please type your first name');
      return false;
  }
  else if (document.registrationform.lname == '') {
      alert('Please type your first name');
      return false;
  }
  // more conditions here
  else {
  alert("Your ID number and password will send to your email address when the casher confirm your enrollment");
  return true;
  }
}

如果您不想使用插件，我推荐一个简单的（例如 jQuery）解决方案：

$(document).on("submit", "form", function() {
    var form = $(this);

    if (form.find("input[name=fname]").val() == '') {
        alert('Error: FNAME is empty!');
        return false; // important
    }

    // more validation
});

顺便一提：

  • 不要id多次使用具有相同值的 - 属性。它必须是独一无二的。否则使用class- 属性。

  • 下次只贴相关代码（form+js）

  • 验证您的 HTML。

祝你好运！
