Question

这是我的注册表单，在我添加验证后，我的记录无法插入到数据库中。但是我的验证工作正常。如果我交换了验证代码和mysql，即使我的错误也可以插入到数据库中验证

<?php
$fnameErr=$lnameErr=$passErr=$repassErr=$icErr=$emailErr=$add1Err=$add2Err=$postErr=$mobileErr="";
$fname=$lname=$pass=$repass=$ic=$email=$add1=$add2=$postcode=$mobile="";

if (isset($_POST['submitbtn']))
{
    $fname    = $_POST['bname'];
    $lname    = $_POST['lname'];
    $pass     = $_POST['bpass'];
    $repass   = $_POST['bconpass'];
    $ic       = $_POST['bic'];
    $email    = $_POST['bemail'];
    $add1     = $_POST['badd1'];
    $add2     = $_POST['badd2'];
    $postcode = $_POST['bpostcode'];
    $mobile   = $_POST['bmobile'];
    $country  = $_POST['bcountry'];
    $state    = $_POST['bstate'];

对于我可怜的英语，我很抱歉。

Answer 1

if (empty($errors) === true)

在您发布的代码中，您之前没有定义$errors。根据{{3}}，如果变量不存在，那么empty()将返回true。因此，除非您遗漏了某些内容，否则您的代码将始终输入if语句的第一部分，而不是第二部分。

我怀疑您要将该行更改为if (empty($errors) === false)，以便只有在错误时才输入代码的那一部分。

Answer 2

对于像$test这样的变量的使用应该非常小心，如果是字符串则应该是'.$test.'。您还应该使用mysqli

无法将我的记录插入数据库？
