Question

我想通过ID和电子邮件进行检查，但下面的代码不起作用，谢谢你帮助我执行以下步骤

通过facebook id进行验证

如果有id ==＆gt;更新BD并重定向home.php
如果id不存在，我们将检查BD上是否存在电子邮件（从Facebook检索）
if yes ==＆gt;显示“此电子邮件已被使用”

如果不是==＆gt;在数据库上插入并==＆gt;重定向到home.php

$cont = $idf;

$idf = $user_profile['id'];

$email = $user_profile['email'];

$query = "SELECT idf from users where idf = $idf ";
$result = mysql_query($query);


if(mysql_num_rows($result) > 1)


{
    // row exists. so update

    mysql_query("UPDATE users SET name = '".$name."', birthday = '".$birthday."', gender = '".$gender."', email = '".$email."' WHERE idf = '".$idf."';") or die(mysqli_error());

header( "refresh:4;url=/home.php" );

} 

else 

{

$sql1 = "SELECT * FROM users WHERE email = $email ";
   $result1 = mysqli_query($mysqli,$sql1) or die(mysqli_error());

   if (mysqli_num_rows($result1) > 0)



 echo "This Email is already used.";

}

  else


{

    // row  does not exists. so create new
    //insertion dans la base de donnée
$sql= mysql_query("INSERT INTO users (name, email, birthday, gender,idl,idf ) VALUES ('".$name."', '".$email."', '".$birthday."', '".$gender."',NULL,'".$idf."');");

//mysql_query ($sql) or die ('Erreur SQL !'.$sql.'<br />'.mysql_error());


//echo 'Le cookie existe   ' . $cont . '<br />';

mysql_close();

setcookie("cokiz", $cont, time()+3600, "/", "NDD");
setcookie("cokiz", $cont, time()+3600, "/", "NDD");

header( "refresh:4;url=/home.php" );


}
}


?>

Answer 1

    use this this will work i think so , use myl_sqli_query  or  mysql_query

    $cont = $idf;

    $idf = $user_profile['id'];

    $email = $user_profile['email'];

    $query = "SELECT idf from users where idf = $idf ";
    $result = mysql_query($query);


    if(mysql_num_rows($result) > 1)


    {
        // row exists. so update

        mysql_query("UPDATE users SET name = '".$name."', birthday = '".$birthday."', gender = '".$gender."', email = '".$email."' WHERE idf = '".$idf."';") or die(mysqli_error());

    header( "refresh:4;url=/home.php" );

    } 

    else 

    {

    $sql1 = "SELECT * FROM users WHERE email = $email ";
       $result1 = mysql_query($mysql,$sql1) or die(mysql_error());

       if (mysql_num_rows($result1) > 0)



     echo "This Email is already used.";

    }

      else


    {

        // row  does not exists. so create new
        //insertion dans la base de donnée
    $sql= mysql_query("INSERT INTO users (name, email, birthday, gender,idl,idf ) VALUES ('".$name."', '".$email."', '".$birthday."', '".$gender."',NULL,'".$idf."');");

    //mysql_query ($sql) or die ('Erreur SQL !'.$sql.'<br />'.mysql_error());


    //echo 'Le cookie existe   ' . $cont . '<br />';

    mysql_close();

    setcookie("cokiz", $cont, time()+3600, "/", "NDD");
    setcookie("cokiz", $cont, time()+3600, "/", "NDD");

    header( "refresh:4;url=/home.php" );


    }
    }


    ?>

Answer 2

错误是你错过了

行之前：

echo "This Email is already used.";

Answer 3

此代码没问题:(仅通过ID验证）：

$idf = $user_profile['id'];

$cont = $idf;

$query = "SELECT idf from users where idf = $idf ";
$result = mysql_query($query);


if(mysql_num_rows($result) > 1)
{
    // row exists. so update

    mysql_query("UPDATE users SET name = '".$name."', birthday = '".$birthday."', gender = '".$gender."', email = '".$email."' WHERE idf = '".$idf."';");
} else {
//echo $email;
    // row  does not exists. so create new
    //insertion dans la base de donnée
$sql= mysql_query("INSERT INTO users (name, email, birthday, gender,idl,idf ) VALUES ('".$name."', '".$email."', '".$birthday."', '".$gender."',NULL,'".$idf."');");

//mysql_query ($sql) or die ('Erreur SQL !'.$sql.'<br />'.mysql_error());


//echo 'Le cookie existe   ' . $cont . '<br />';

mysql_close();

setcookie("cokiz", $cont, time()+3600, "/", "NDD");
setcookie("cokiz", $cont, time()+3600, "/", "NDD");

header( "refresh:4;url=/home.php" );


}

?>

但是当我通过邮件添加验证时：它不起作用（下面的代码）

$cont = $idf;

    $idf = $user_profile['id'];

    $email = $user_profile['email'];

    $query = "SELECT idf from users where idf = $idf ";
    $result = mysql_query($query);


    if(mysql_num_rows($result) > 1)




    {
        // row exists. so update

        mysql_query("UPDATE users SET name = '".$name."', birthday = '".$birthday."', gender = '".$gender."', email = '".$email."' WHERE idf = '".$idf."';");


    } 

    else 

    {

    $sql1 = "SELECT * FROM users WHERE email = $email ";
       $result1 = mysql_query($mysql,$sql1) or die(mysql_error());


       if (mysql_num_rows($result1) > 0)

 {

     echo "This Email is already used.";

    }

      else


    {

        // row  does not exists. so create new
        //insertion dans la base de donnée
    $sql= mysql_query("INSERT INTO users (name, email, birthday, gender,idl,idf ) VALUES ('".$name."', '".$email."', '".$birthday."', '".$gender."',NULL,'".$idf."');");

    mysql_query ($sql) or die ('Erreur SQL !'.$sql.'<br />'.mysql_error());


    //echo 'Le cookie existe   ' . $cont . '<br />';

    mysql_close();

    setcookie("cokiz", $cont, time()+3600, "/", "NDD");
    setcookie("cokiz", $cont, time()+3600, "/", "NDD");

    header( "refresh:4;url=/home.php" );

    }
    }



    ?>

有人有个主意吗？谢谢
