嘿，我想问一下“如果我们注册失败后如何保留表格价值？”

这是我的register.php：

<?php
ob_start();
session_start();
if( isset($_SESSION['user2'])!="" ){
 header("Location: home.php");
}
include_once 'serverconfig.php';

if(isset($_POST['btn-signup'])) {
$alpha = "abcdefghijklmnopqrstuvwxyz";
$alpha_upper = strtoupper($alpha);
$numeric = "0123456789";
$special = ".-+=_,!@$#*%<>[]{}";
$chars = "";

if (isset($_POST['gencode'])){
    // if you want a form like above
    if (isset($_POST['alpha']) && $_POST['alpha'] == 'on')
        $chars .= $alpha;

    if (isset($_POST['alpha_upper']) && $_POST['alpha_upper'] == 'on')
        $chars .= $alpha_upper;

    if (isset($_POST['numeric']) && $_POST['numeric'] == 'on')
        $chars .= $numeric;

    if (isset($_POST['special']) && $_POST['special'] == 'on')
        $chars .= $special;

    $length = $_POST['length'];
}else{
    // default [a-zA-Z0-9]{9}
    $chars = $alpha . $alpha_upper . $numeric;
    $length = 9;
}

$len = strlen($chars);
$gc = '';

for ($i=0;$i<$length;$i++)
        $gc .= substr($chars, rand(0, $len-1), 1);

// the finished password
$gc = str_shuffle($gc);

 $namalengkap_ = trim($_POST['namalengkap']);
 $email_ = trim($_POST['email']);
 $nomorhape_ = trim($_POST['nomorhape']);
 $jeniskelamin_ = trim($_POST['jeniskelamin']);
 $tanggallahir_ = trim($_POST['tanggallahir']);
 $username_ = trim($_POST['uname']);
 $password_ = trim($_POST['upass']);

 $namalengkap = strip_tags($namalengkap_);
 $email = strip_tags($email_);
 $nomorhape = strip_tags($nomorhape_);
 $jeniskelamin = strip_tags($jeniskelamin_);
 $tanggallahir = strip_tags($tanggallahir_);
 $username = strip_tags($username_);
 $password = strip_tags($password_);

 // check email exist or not
 $query = "SELECT email FROM user2 WHERE email='$email'";
 $result = mysql_query($query);
 $query2 = "SELECT username FROM user2 WHERE username='$username'";
 $result2 = mysql_query($query2);

 $count = mysql_num_rows($result); // if email not found then proceed
 $count2 = mysql_num_rows($result2);

 if ($count==0 && $count2==0) {
  $query = "INSERT INTO user2(namalengkap,email,jeniskelamin,tanggallahir,username,password,activecode,status) VALUES('$namalengkap','$email','$jeniskelamin','$tanggallahir','$username','$password','$gc','0')";
  $res = mysql_query($query);

  if ($res) {
   $errTyp = "success";
   $errMSG = "Registrasi Berhasil !";
  } else {
   $errTyp = "danger";
   $errMSG = "Ada Kesalahan Saat Mengisi Form Di Bawah, Silahkan Cek Kembali";
  } 

 } else {
  $errTyp = "warning";
  $errMSG = "E-Mail/Username Sudah Digunakan Oleh User Lain. Silahkan Daftar E-Mail,&nbsp;";
  $errMSG .= "<a href=\"mail/register.php\" target=\"_blank\">Klik Disini</a>";
 }
}
?>

我该怎么办这个剧本？

看看此示例可能会对您有所帮助PHP Form validation

答案 1 :(得分：0)

使用这样的东西：

<input type="email" name="email" class="form-control" placeholder="Masukan Alamat Email Anda" pattern="^[A-Za-z@.0-9]*$" title="Masukan E-Mail yang Valid(Aktif)" value="<?php isset($_REQUEST['email']) ? $_REQUEST['email'] : '' ?>" required />

此

value="<?php if(isset($_REQUEST['email'])) { echo $_REQUEST['email']; } ?>"

将在文本框中保留不成功处理的值。
