My test code is as follows:

<?
    session_start();
    $nome = filter_input(INPUT_POST, 'nome');
    $_SESSION['nome'] = $nome;  

  ?>
  <form action="teste.php" method="post">

    <input type="text" name="nome"> <br> <br>
    <button>Enviar</button>
  </form>

<?php
  session_start();

  if($_SESSION['nome'] == 'sim' ) {
    echo 'Logado'; // Ele não entra aqui
  } else {
    header('location: index.php?login=erro'); // Ele so fica na pagina index, independente do valor passado no input
  }

Now if I do so it logs, but it logs the user independent of the value passed in the input

session_start();

  if($_SESSION['nome'] != 'sim' ) {
    echo 'Logado'; //Ele entra aqui
  } else {
    header('location: index.php?login=erro');
  }
php

  • Yes my logic would be this, but any value I type including the yes it enters the login.

session_start();

  if($_SESSION['nome'] != 'sim' ) {
    header('location: index.php?login=erro');
  } else {
    echo 'Logado'; //Ele entra aqui;
  }

N the IF syntax o == It is to compare if the value is equal and qunado this as != shows that it is different, ie, would be an Else within the comparison.... the correct is to reverse.
