PHP session does not work

I have a system from which I use session to validate the user. For validation I use the code below:

<?php
session_start();
 public function validaUsuarios($loginUsuario,$senhaUsuario){
       .......
       $_SESSION['logado'] = true;
        header('location: entrar.php');
......
?>

And on the page enter.php:

<?php
session_start();
if($_SESSION['logado'] == false || $_SESSION['logado'] == ''){
    header('location: index.php');
}else{
 ...........

What I do not understand is that in other servers worked perfectly, but this server does not take first, IE, when giving a print, does not pass any value in the session.

php

  • The function validaUsuarios is within a class?

  • Yes. It is inside a class and at the top I put session_start(). <? php session_start(); class Extends Methods Connect{

  • what I find strange is that it returns to the login page and when soon me again, he "sees" the value and I can access.

  • Try to put exit(); below redirects. For example: header('location: entrar.php'); exit();

  • I put it, but it didn’t work. The session still doesn’t get the value right the first time, only the second time....

  • Try to see the contents of $_SESSION right after the line $_SESSION['logado'] = true; to see if you are in session. ex.: var_dump($_SESSION);die; Maybe the problem isn’t in the piece of code you posted.

  • I did it the way you asked and it appears the values, IE, the value is created, but when it arrives in the other page, the value arrive empty.

  • I would say it has something to do with Handler’s mistakes. Try changing the if($_SESSION['logado'] == false || $_SESSION['logado'] == ''){ for if(isset($_SESSION['logado']) === false){ because in fact, at the first moment there is no index 'logged in' and your server may be returning a Warning and not false or empty.

  • Hi, Gê. The problem is that in the address page there is no value in $_SESSION['logged in], that is, when I do the validation the value appears as 1, but when it arrives in the page that is directed, the value arrives empty.

  • Create a phpinfo.php file, put the <?php phpinfo(); ? > save the return and put it somewhere so we can analyze.

  • If possible send from a working server and one that doesn’t work, it may be some configuration on the server.

Check if you have write permission in the tmp folder, or in another folder in which php is configured to save the session files;

In any case, check the server’s php.ini settings and try to force settings using ini_set. Possible settings for sessions you can find in http://php.net/manual/en/session.configuration.php.

Hello! Dear ones, I went through a search similar to my application hosted at Locaweb, the support did not help much, I sent the example below to them and returned me another example, using form (html) and passing the value via post to a session, then sending it to another page... anyway, there was no way to use this methodology every time I had to work with the sessions, and using my method my sessions ceased to exist in pg2.php. It had the following testing structure in the domain:

index php.

<?php
    session_start();
    $_SESSION["texto"] = "teste";
    echo "<a href=\"pg2.php\">clique aqui</a>";
?>

pg2.php

<?php 
    session_start();
    echo $teste = $_SESSION["texto"];
?>

The solution I found was... Change the path of Session.save_path in php.ini; and Enable the ob_start output buffer();

The structure became this: index php.

<?php
    ob_start();
    session_start();
    $_SESSION["texto"] = "teste";
    echo "<a href=\"pg2.php\">clique aqui</a>";
?>

pg2.php

<?php
    ob_start();
    session_start();
    echo $teste = $_SESSION["texto"];
?>
