The result of this error page:

Notice: Undefined variable: name in C: xampp htdocs Techphp profile.php on line 57, line 58, line 59 and line 60,

Which are the lines where the user profile data is.

Which I don’t understand why this is working. Is it not connected?

<?php 
mysql_connect("localhost", "root", "angola") or die("cannot connect");
mysql_select_db("login_senha");


session_start();
$login =  $_SESSION['login_usuario'];

$login =  $_SESSION['login_usuario']=$login;
$sql = mysql_query( "SELECT * FROM usuario WHERE  login='$login'");
while($linha= mysql_fetch_array($sql)){
    $nome=$linha['nome']; 
    $email=$linha['email'];
    $idade=$linha['idade'];
    $cidade=$linha['cidade'] ;
    $foto=$linha['foto'] ;

}
?>

You can elaborate as follows:

<?php
    session_start();
    mysql_connect("localhost", "root", "angola") or die("cannot connect");
    mysql_select_db("login_senha");

    $login = $_SESSION['login_usuario'];
    $sql = mysql_query( "SELECT * FROM usuario WHERE  login='{$login}'");
    $linha = mysql_fetch_array($sql);

?>

Remembering that Login is coming from session, look also check his password, to see if it matches the registered password, but in this case he is already logged in? I did not understand well... But try to elaborate as I suggest.

  • Okay, I’ll make these changes thank you from my heart

  • Okay! Anything let us know!

  • OK any doubt I’ll give you news

  • It was executed in this order but it appears with the following news: Notice: Undefined index: login_usuario in C: xampp htdocs Techphp profile.php on line 6 this I didn’t understand until the login page is $login = $_SESSION['login_usuario']; I don’t understand what’s wrong with the index of line 6 where it’s registered: $login = $_SESSION['login_usuario'];

  • Where are you looking for Login? It usually comes by Session or post or get?

  • it is in no post: $login = $_POST['login'];

  • Then, just change $login = $_SESSION['login_usuario']; to $login = $_POST['login'];

  • now it shows me the error in line 8: Notice: Undefined variable: login in C: xampp htdocs Techphp profile.php on line 8: $sql = mysql_query( "SELECT * FROM user WHERE login='{$login}'");

  • Swap $sql = mysql_query( "SELECT * FROM usuario WHERE login='{$login}'"); for $sql = mysql_query( "SELECT * FROM user WHERE login='{$login}'") or print mysql_error();

  • Obs:sorry I messed up the line still error on line 6 :Notice: Undefined index: login in C: xampp htdocs Techphp profile.php on line 6: where this the $login = $_POST['login'];

  • I’ll send you the whole process of the pages ok,

  • Okay, put it here in your question.

  • OK I’ll send in the question

Change this excerpt:

$login =  $_SESSION['login_usuario'];

$login =  $_SESSION['login_usuario']=$login;

For this:

if( !isset($_SESSION['login_usuario']))
   die('Usuario nao logado');

$login = $_SESSION['login_usuario'];

And change this passage:

$sql = mysql_query( "SELECT * FROM usuario WHERE  login='$login'");

For this:

$sql = mysql_query( "SELECT * FROM usuario WHERE  login='$login'");
if(mysql_num_rows($sql) == 0 )
 die('O usuario '.$login.' não existe');

It’ll do, or at least help you understand your own code.
