Question

我有以下问题：我有一个注册表。响应消息将通过javascript函数（colorbox）显示，该函数将通过php变量调用。

看起来像：

<?php if ($result):?>
  <script type="text/javascript">no need to post, it is working fine</script>
<?php endif; ?>

该变量无法正常工作。如果我设置：

<?php if **(isset($_POST['submitted']))**: ?>
  <script type="text/javascript"> no need to post it is working</script>
<?php endif; ?>

它工作正常。

问题是，当我要提交表格时。即使未正确填写注册表单，该框也会启动。为了避免这个问题，我想我必须找到一个类似布尔值true或false的变量，如果该表单以正确的方式填充哪个答案来自我的服务器。我的想法就像：

$sql = mysql_query("INSERT INTO tabelle (x1, x2...) VALUES('$x1','$x2')") 
       or die (mysql_error()); 

if ($result = mysql_affected_rows() = 2) {
  return TRUE;
} 

$result = mysql_affected_rows(); 
$result = mysql_query($sql);

通过这种方式，我可以将变量$result更改为应该有效的子句。它没有。：（

我做错了什么？

Answer 1

在您的代码中

$sql = mysql_query("INSERT INTO tabelle (x1, x2...) VALUES('$x1','$x2')") 
       or die (mysql_error()); 

if ($result = mysql_affected_rows() = 2) {
  return TRUE;
} 

$result = mysql_affected_rows(); 
$result = mysql_query($sql);

为什么你回来了？如果这样做，它将无法到达后来的行。

此外，您在mysql_query($sql)中使用$ sql，它已经是一个mysql结果资源。

如果您想在查询成功时显示

<?php
  ..
   $sql = mysql_query("INSERT INTO tabelle (x1, x2...) VALUES('$x1','$x2')") 
       or die (mysql_error()); 

if (mysql_affected_rows() == 2){ ?>
  <script type="text/javascript">no need to post, it is working fine</script>

<?php } ?>

Answer 2

这段代码有很多错误。

这样做：

<?PHP
$success = false;
$result = mysql_query("INSERT INTO tabelle (x1, x2...) VALUES('$x1','$x2')") or die (mysql_error()); 
if ($affected = mysql_affected_rows() == 2) { $success = true; }
?>
<?PHP if ($success){ ?>
<script type="text/javascript">no need to post, it is working fine</script>
<?PHP } ?>

很抱歉，如果不能完全奏效，你会对我（'_ POST ['提交']）部分感到困惑，你的问题并不完全清楚。

只是为了显示整个代码。以下所有查询都有效。

    <?php

$errorMsg = "";
$x1 = "";
$x2 = "";

     $x4 = $_POST['x4'];
     $email = $_POST['email'];
     $password = $_POST['password'];
     $x7= $_POST['x7'];

         $x1 = stripslashes($x1);
     $x2 = stripslashes($x2);
         $x3 = stripslashes($x3);
     $x4 = stripslashes($x4);
     $email = stripslashes($email);
     $password = stripslashes($password);
     $x7= stripslashes($x7);

         $x1 = strip_tags($x1);
     $x2 = strip_tags($x2);
     $x3 = strip_tags($x3);

     $email_check = mysql_num_rows($sql_email_check); 

     if ((!$x1) || (!$x2) || (!$x3) || (!$x4) || (!$email) || (!$password) || (!$x7)) { 

     $errorMsg = 'following issues are missing<br />';

    if(!$x1){ 
       $errorMsg .= ' *x1<br />'; 
     } 
     if(!$x2){ 
       $errorMsg .= ' *x2<br />';
     } 
     if(!$x3){

     } else if ($email_check > 0){

     $email = eregi_replace("`", "", $email);

     $db_password = md5($password); 

     $sql = mysql_query("INSERT INTO tablename (x1, x2, x3, x4, sign_up_date, email, password)    

     VALUES('$x1','$x2','$x3','$x4', now(), '$email','$db_password')")  

     or die (mysql_error()); 

     $id = mysql_insert_id();

     /*mkdir("members/$id", 0755); */

    $to = "$email"; 

    $from = "xxx@xxx.xx";

    $message = "Link for activation";

    $headers  = "From: $from\r\n";
    $headers .= "Content-type: text\r\n";

    mail($to, $subject, $message, $headers);

   $msgToUser = "text";


   /*include_once 'msgToUser.php';  */



   exit();
