我是php的新手，如果我看起来很傻，请原谅我。我仍然在网上论坛和堆栈社区的帮助下一步一步地学习。

我在网上有一个表格，代码如下：

<?php
define('DIR_APPLICATION', str_replace('\'', '/', realpath(dirname(__FILE__))) . '/');
include(DIR_APPLICATION."config.php");
ob_start();
session_start();
$msg = 'none';
$sql = '';
if(isset($_POST['email']) && $_POST['email'] != '' && isset($_POST['password']) && $_POST['password'] != ''){
  if($_POST['usertype'] == 'admin'){
    //here for admin
    $sql= mysql_query("SELECT * FROM admin WHERE a_email = '".make_safe($_POST['email'])."' and password = '".make_safe($_POST['password'])."'",$link);
  }
  else if($_POST['usertype'] == 'teacher'){
    //here for teacher
    $sql= mysql_query("SELECT * FROM teacher WHERE t_email = '".make_safe($_POST['email'])."' and t_password = '".make_safe($_POST['password'])."'",$link);
  }
  else if($_POST['usertype'] == 'student'){
    //here for student
    $sql= mysql_query("SELECT * FROM student WHERE s_email = '".make_safe($_POST['email'])."' and s_password = '".make_safe($_POST['password'])."'",$link);
  }
  else if($_POST['usertype'] == 'parents'){
    //here for parent
    $sql= mysql_query("SELECT * FROM parent WHERE p_email = '".make_safe($_POST['email'])."' and p_password = '".make_safe($_POST['password'])."'",$link);
  }
  else if($_POST['usertype'] == 'librarian'){
    //here for employee
    $sql= mysql_query("SELECT * FROM user WHERE u_email = '".make_safe($_POST['email'])."' and u_password = '".make_safe($_POST['password'])."'",$link);
  }
  else if($_POST['usertype'] == 'accountant'){
    //here for employee
    $sql= mysql_query("SELECT * FROM user WHERE u_email = '".make_safe($_POST['email'])."' and u_password = '".make_safe($_POST['password'])."'",$link);
  }
  if($row = mysql_fetch_array($sql)){
    //here success
    $_SESSION['objLogin'] = $row;
    $_SESSION['login_type'] = $_POST['usertype'];
    if($_POST['usertype'] == 'admin'){
      header("Location: dashboard.php");
      die();
    }
    else if($_POST['usertype'] == 'teacher'){
      header("Location: t_dashboard.php");
      die();
    }
    else if($_POST['usertype'] == 'student'){
      header("Location: s_dashboard.php");
      die();
    }
    else if($_POST['usertype'] == 'parents'){
      header("Location: p_dashboard.php");
      die();
    }
    else if($_POST['usertype'] == 'accountant'){
      header("Location: a_dashboard.php");
      die();
    }
    else if($_POST['usertype'] == 'librarian'){
      header("Location: l_dashboard.php");
      die();
    }
  }
  else{
    $msg = 'block';
  }
}
function make_safe($variable) 
{
   $variable = strip_tags(mysql_real_escape_string(trim($variable)));
   return $variable; 
}
?>

此表单效果很好。

但我的问题是我正在为这个在线版本创建一个Android表单，我需要一个json响应。所以我在浏览器中尝试了以下内容：

mydomain.com/index.php?email=user@example.com&password=mypass&usertype=student

这会产生相同的页面。

我很困惑，为什么这不进入页面。 我可以理解，在某个地方，我错了，但无法理解。

请帮忙。

答案 0 :(得分：0)

@Akhil @Vijay和@MiguelJimenez建议

我将$_POST更改为$_REQUEST，它就像一个魅力

所以，如果有人在这个问题上遇到困难，这可能会对你有所帮助。
