good afternoon i made a system, bd ok and loguin check ok however wanted after checking the user it open the right page for the user certain example: I have 3 levels being 0 1 2 and I want the user level 0 open the page index1.php the level user 1 open the page index2.php and the level user 2 open the page index3.php

<?php

session_start(); // Inicia a session

include "config.php";

$usuario = $_POST['usuario'];
$senha = $_POST['senha'];

if ((!$usuario) || (!$senha)){

  echo "Por favor, todos campos devem ser preenchidos! <br /><br />";

  include "index.html";

}else{

  $senha = md5($senha);

  $sql = mysql_query(

    "SELECT * FROM xxxxxx_usuarios
    WHERE usuario='{$usuario}'
    AND senha='{$senha}'
    AND ativado='1'"

  );

  $login_check = mysql_num_rows($sql);

  if ($login_check > 0){

    while ($row = mysql_fetch_array($sql)){

      foreach ($row AS $key => $val){

        $$key = stripslashes( $val );

      }

      $_SESSION['usuario_id'] = $usuario_id;
      $_SESSION['nome'] = $nome;
      $_SESSION['sobrenome'] = $sobrenome;
      $_SESSION['email'] = $email;
      $_SESSION['nivel_usuario'] = $nivel_usuario;

      mysql_query(

        "UPDATE xxxxx_usuarios SET data_ultimo_login = now()
        WHERE usuario_id ='{$usuario_id}'"

      );

      header("Location: separador.php");


    }

  }else{

    echo "Você não pode logar-se! Este usuário e/ou senha não são válidos!<br />Por favor tente novamente!<br />";

    include "index.html";

  }

}

?>

where when it executes the header("Location: separator.php") directs the open and validated user to its right page tried commands with if Else switch but Nunk get some idea.

this is the.php separator file

<?php

$nivel = $_SESSION['nivel_usuario'];

if ($nivel == 0){
    header("location: /NORMAL/inicio.html");
} else if ($nivel == 1){
    header("location: /PREMIUM/index.html");
} else if ($nivel == 2){
    header("location: /ADM/index.html");
} else {
    header("location: index.html");
} 
?>
php

  • How do you know the user level? You are in the bank?

  • Yes this in the bank discriminated

  • I was able to resolve relocating the code inside the verification page as proposed by @João Victor Souza... Personal upgrade

  • Now that we’ve seen your.php tab, it’s clear that session_start() is missing; at the beginning of the page

After the author has posted the page separador.php note the absence of session_start()

put session_start(); at the beginning of the.php tab that will work

<?php

session_start();

$nivel = $_SESSION['nivel_usuario'];

if ($nivel == 0){
    header("location: /NORMAL/inicio.html");
} else if ($nivel == 1){
    header("location: /PREMIUM/index.html");
} else if ($nivel == 2){
    header("location: /ADM/index.html");
} else {
    header("location: index.html");
} 
?>

If not put session_start(); will fall on parole 0 whether it is in the if or any else if

<?php

$nivel = $_SESSION['nivel_usuario'];

if ($nivel == 1){
    header("location: /NORMAL/inicio.html");
} else if ($nivel == 2){
    header("location: /PREMIUM/index.html");
} else if ($nivel == 0){

    /******* Vai redirecionar para esta página *******/
    header("location: /ADM/index.html");
    /************************************************/

} else {
    header("location: index.html");
} 
?>

'Cause I get paroled == 0?

Because if the session is not started $_SESSION['nivel_usuario'] there is no - check with var_dump($_SESSION['nivel_usuario']) - and $nivel will be NULL, therefore, for PHP NULL == 0 consequently $nivel == 0 is true

Another solution would be to allocate the code

$nivel = $_SESSION['nivel_usuario'];

if ($nivel == 0){
    header("location: /NORMAL/inicio.html");
} else if ($nivel == 1){
    header("location: /PREMIUM/index.html");
} else if ($nivel == 2){
    header("location: /ADM/index.html");
} else {
    header("location: index.html");
}

within the verification page instead of header("Location: separador.php");

You may not need the page separador.php, you can simply use the header to take you to the right place, like this:

//Depois de receber o nivel do usuario na session defina a qual pagina será redirecionado
$_SESSION['nivel_usuario'] = $nivel_usuario;

if($nivel_usuario == 1){
    $pagina = "index.php";
}else if($nivel_usuario == 2){
    $pagina = "index2.php";
}else{
    $pagina = "index3.php";
}

//Depois é só concatenar a variavel pagina com o header
header("location:".$pagina.")";

But if you still prefer to redirect to the page separador.php, can do the following there:

$tipo = $_SESSION['nivel_usuario'];

if($tipo == 1){
    header("location: index.php");
}else if($tipo == 2){
    header("location: index2.php");
}else{
    header("location: index3.php");
}

  • sorry my ignorance but this last one would not direct direct to the index3

  • He would only redirect to index3.php if the type was not equal to 1 or equal to 2

  • You can also add one last if to check if it is equal to 3, but I do not believe that it is necessary, would thus be the last: }else if($tipo == 3){ header("location: index3.php"); }

  • I’m using if chained or Else if, if you do not know can read more about in the php documentation : Structure Else if

  • good day this option inside the tab only forwards to type 2 even though I am type 1 kkkk tava perdidao even with little knowledge in php

  • Good morning @Eduardosaraiva, try quoting the comparison to see if it goes, like this: ($tipo == "1"), do with everyone

  • put and played straight into the error

  • You’re wearing session_start(); on the page php separator. ?? if not, try this

Direct to the page, and if any different value opens an error/access denied page:

$nivel = $_SESSION['nivel_usuario'];

if ($nivel == 1){
    header("location: index1.php");
} else if($nivel == 2){
    header("location: index2.php");
} else if($nivel == 3){
    header("location: index3.php");
} else {
    header("location: erro.php");
}

You can use any other condition structure. Simply filter and direct with the header.
