Goodday house，我正在开发这个网站，它有一个注册/登录页面作为我的第一个项目，我现在正在努力。 我在我的注册表单中添加了php验证，但是数据库插入语句拒绝工作，虽然所有条件语句都已完成，但我尝试在insert语句后立即执行重定向循环，但我的脚本会自动（以某种方式）跳转＆＃34; Insert语句＆＃34;并处理重定向代码.. 这是下面的代码
<!-- Php validation-->
<?php
include 'var.php';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$errors = array(); // Starts an array to store errors.
//Validation rules involves trimming,validating and sanitizating
$name = trim($_POST['name']);
$strippedname = mysqli_real_escape_string($con, strip_tags($name)) ;
$length = mb_strlen($strippedname, 'utf-8') ;
if ($length < 8 ) {
$errors[]= 'Your full name shouldn\'t be less than 8 letters' ;
} else {
$name = $strippedname ;
}
$email = FALSE ;
if (empty($_POST['email'])) {
$errors[] = 'You didn\'t provide any email address' ;
} // Next is removal of spaces and validation.
if (filter_var((trim($_POST['email'])), FILTER_VALIDATE_EMAIL)) {
$email = mysqli_real_escape_string($con, (trim($_POST['email'])));
}
else {
$errors[] = 'Email address was provided in the wrong format';
}
$pho = trim($_POST['phone']) ; // next line of code removes all characters that aren't digits
$phon = preg_replace('/\D+/', '', ($_POST['phone']));
$strippedphone = mysqli_real_escape_string($con, strip_tags($phon));
$length = mb_strlen($strippedphone, 'utf-8') ;
if ($length <> 11 ) {
$errors[] = 'Phone number should contain only eleven digits';
}
else {
$phone = $strippedphone ;
}
$add = trim($_POST['address']) ;
$strippedadd = mysqli_real_escape_string($con, strip_tags($add)) ;

$errors[]= 'Address should not be lesser than 15 letters' ;
} else {
$address = $strippedadd ;
}
if (empty($_POST['gender'])) {
$errors[] = 'You didn\'t select a gender';
} else {
$gend = trim($_POST['gender']);
}
$user = trim($_POST['username']);
$strippeduser = mysqli_real_escape_string($con, strip_tags($user)) ;
$length = mb_strlen($strippeduser, 'utf-8') ;
if ($length < 6) {
$errors[] = 'Username should contain a minimum of 6 letters and maximum of 18';
} else {
$confirmeduser = $strippeduser ;
}
if (empty($_POST['password'])){
$errors[] ='Please enter a valid password';
}
if(!preg_match('/^\w{10,40}$/', $_POST['password'])) {
$errors[] = 'Invalid password, use 10 to 40 characters without applying spacing.';
} else{
$password = $_POST['password'];
}
if($_POST['password'] == $_POST['confirm_password']) {
$pass = mysqli_real_escape_string($con, trim($password));
$newpass = password_hash($pass, PASSWORD_DEFAULT) ;
}else{
$errors[] = 'passwords don\'t match.';
}
if(empty($errors)) { // If no problems occurred
//Determine whether the email address has already been registered for a user
$query = mysqli_query($con, "INSERT INTO `customer`(`name`, `email`,
`phone`, `address`, `gender`, `username`, `password`) VALUES($name,$email,$phone,
$address,$gend,$confirmeduser,$newpass)") ;
echo "Done";
// end of mysqli_num_Rows
} // End of if (empty($errors))
else{ // Display the errors if any are found.
echo '
<p class="error">The following error(s) were found in the submitted form :<br>';
foreach ($errors as $msg) { // Echo each error
echo " $msg<br>";
}
}
}
?>
这是html表单

非常感谢您的回复

由于我们很可能处理字符串，这些变量在您的VALUES
中($name,$email,$phone,$address,$gend,$confirmeduser,$newpass)
需要引用：
('$name','$email','$phone','$address','$gend','$confirmeduser','$newpass')
您是否使用or die(mysqli_error($con))至mysqli_query()
会发出引号错误的信号。
旁注：
您应该使用prepared statements或PDO with prepared statements，他们更安全。
另外注意到Barmar发现：
<?phpinclude 'var.php';
php和include
<?php include 'var.php';
除非是复制/粘贴错误或拼写错误。
再次和>?，另一个应该是?>
在PHP方面：
将error reporting添加到文件的顶部，这有助于查找错误。
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
// rest of your code
旁注：错误报告应仅在暂存时完成，而不是生产。
