如何用php编写注册表格,发布PHP-MySQL注册表格

表单提交后，浏览器只显示空白页面。没有其他的。我已启用错误报告。在PHP日志中没有错误。也试过(如你所见)echo $sql; die();。仍然没有结果。如何解决它？我的代码有什么问题？我的PHP代码(处理申请表单的数据)看起来像发布PHP-MySQL注册表格

require '../includes/db.php';

require '../includes/ipurl.php';

require '../includes/common.php';

$page = 'signup';

if (mysqli_connect_errno()) {

printf("Connect failed: %s\n", mysqli_connect_error());

exit();

}

if ($_POST['submit'] == 'Tamam') {

$err = array();

foreach ($_POST as $key => $value) {

$data[$key] = filter($value);

}

if (empty($data['fname']) || strlen($data['fname']) < 2 || empty($data['mname']) || strlen($data['mname']) < 2 || empty($data['lname']) || strlen($data['lname']) < 2) {

$err[ ] = 1;

}

if (!isUserID($data['login'])) {

$err[ ] = 2;

}

if (!isEmail($data['email'])) {

$err[ ] = 3;

}

if (!checkPwd($data['pwd'], $data['pwd2'])) {

$err[ ] = 4;

}

$pwd = PwdHash($data['pwd']);

$host = $_SERVER['HTTP_HOST'];

$host_upper = strtoupper($host);

$path = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');

$activ_code = rand(1000, 9999);

$email = $data['email'];

$login = $data['login'];

$dob = date('Y-m-d', strtotime($data['dob']));

$age = date("Y") - date('Y', strtotime($data['dob']));

$type = $data['type'];

$rs_duplicate = $db->query("select count(*) as total from users where email='$email' OR login='$login'") or die($db->error);

list($total) = $rs_duplicate->fetch_row();

if ($total > 0) {

$err[ ] = 5;

}

if (isset($type)) {

if ($type == 1) {

$region = $data['region'];

$school = $data['school'];

$class = $data['class'];

$group = 0;

$subject = 0;

$university = 0;

$profession = 0;

}

if ($type == 2) {

$group = $data['group'];

$region = $data['region'];

$school = $data['school'];

$class = $data['class'];

$subject = 0;

$university = 0;

$profession = 0;

}

if ($type == 3) {

$group = 0;

$region = 0;

$school = 0;

$class = 0;

$subject = 0;

$university = $data['university'];

$profession = $data['profession'];

}

if ($type == 4) {

$group = 0;

$region = 0;

$school = 0;

$class = 0;

$university = 0;

$profession = 0;

$subject = $data['subject'];

}

}

if (!isset($type)) {

$err[ ] = 9;

}

if (empty($err)) {

$sql = "INSERT INTO users

(level,fname, mname, lname, dob, age, reg_date, phone, email, login, pwd, type, `group`, region, school, class, ip, subject, ban, university, profession, activation_code)

VALUES

('1','$data[fname]', '$data[mname]', '$data[lname]', '$dob', '$age', now(), '$data[phone]', '$email', '$login', '$pwd', '$type', '$group', '$region', '$school', '$class', '$ip', '$subject', NULL, '$university', '$profession', '$activ_code')";

echo $sql; die();

$result = $db->query($sql) or die(printf("Bazaya daxiletmə zamanı səhv: %s\n", $db->error));

$id = $db->insert_id;

$md5_id = md5($id);

$db->query("update users set md5_id='$md5_id' where id='$id'") or die(printf("Bazaya daxiletmə zamanı səhv: %s\n", $db->error));

include "../includes/success.php";

}

} else if (!empty($err)) {

include "../includes/error.php";

}

?>

顺便说功能filter从common.php杀毒所有帖子

function filter($data) {

$data = trim(htmlentities(strip_tags($data)));

if (get_magic_quotes_gpc())

$data = stripslashes($data);

$data = mysql_real_escape_string($data);

return $data;

}
