Question

我在获取URL参数时遇到问题。

错误如下：

注意：未定义索引：链接到第3行的C：\ xampp \ htdocs + Gesol \ modulos \ login \ form.php

URL的外观如下： http://localhost:82/+Gesol/login/form/ingreso?link=/+Gesol/outdoors-servicios/form/8780

会话代码：

if ($gl_to == "ver"):   //VERIFICA QUE EXISTA SESSION

  if (!isset($_SESSION['id']) or !isset($_SESSION['empresa']) or !isset($_SESSION['user']) or !isset($_SESSION['nombre']) or !isset($_SESSION['email']) or !isset($_SESSION['gesol'])):

         if (isset($Gl_config_cms_url)){
            $link = $_SERVER['REQUEST_URI'];
            header("Location: ".$Gl_config_cms_url."login/form/ingreso?link=$link"); 
            exit(); 
         }else{
            header("Location: ./login/form/ingreso");
            exit(); 
         }

  endif;

endif;

登录表单代码：

<?php

$link = $_GET['link'];

echo $link;
exit;

session_start();
require_once ("../../../global/-gl-abre-conexion-gesol.php");
require_once ("../../global/gl-funciones.php");

$Gl_accion="INQ"; require_once("../../modulos/configuracion/XML-config.php");

#--- Revisa si esta entrando desde https solo si el sitio tiene https activo en la url
if(substr($Gl_config_cms_url,0,5)=="https"):

    if (!isset($_SERVER['HTTPS'])):
        header("Location: ".$Gl_config_cms_url."login/form/ingreso"); 
    endif;

endif;


#--- Valida Usuarios
$Gd_error = "";
if (!empty($_POST))
{
    if (isset($_POST['user']) and isset($_POST['pass']))
        {

        require("SQL-login.php");
        if ($Gl_existe_user=="N")
            {

                $Gd_error =  "Nombre de usuario y/o contraseña no válido. <br/> ¿<a href='./login/lost/password'>Has olvidado tu contraseña</a>? "; 

            }else{

                $Gl_usuario = $Gd_user_id;
                require("../../modulos/usuarios/SQL-tb_gesol_acceso.php");                      
                if ($Gl_existe_miplusAcceso=="S")#---Valida si el usuario tiene acceso a pantallas
                {
                    $gl_to = "crear";
                    require("../../global/gl-session.php");
                    header("Location: ".$Gl_config_cms_url."panel/home/"); 
                    exit();             
                }else{
                    $Gd_error =  "Usuario sin privilegios para ingresar al CMS, favor contacte a su proveedor.";
                }

            }

        }else{

            $Gd_error =  "Ingrese Usuario y contraseña para ingresar al sistema.";

        }

}else{

    $gl_to = "revisa";

如您所见，我正在尝试获取包含我需要的URL的“？link = $ link”。（/+Gesol/outdoors-servicios/form/8780）

Answer 1

快速解答：

<form action="./ingreso" method="post">

您无法通过$ _GET获得链接，您可能会像$ _POST ['link']一样获得链接（如果您通过<input>对象将其设置在表单内部。

替代答案

如果您想真正使用$ _GET变量获取它，则应将其编写为：

<form action="./ingreso?link=http://whatyouwanttowrite..." method="post">

您没有从表单发送POST变量链接。您可以像这样手动设置

<input type="hidden" name="link" value="https://www.google.com">

那么您可以通过$ _POST

获得它

替代解决方案使用结合了$ _GET和$ _POST变量的$ _REQUEST。

$link = $_REQUEST['link'];

抑制错误：您可以输入@来抑制错误。像$link = @$_GET['link'];

Answer 2

首先显示您的登录表单？如果是这样，则表格第3行上的$ _GET ['link']不可用。使其处于混乱状态

Answer 3

因为它找不到您的$ _GET ['link']，但是在您的表单请求之后您看不到此消息。下面的代码可以帮助您。如Shane所说。

if(isset($_GET['link']))
{
    something here...
}
