php login

Question

I would like when arriving at the page with session only one user with certain login but error when I access

php code:

if($_SESSION['login'] == 'admin')
{
echo "logado";
}

It gives error on the part of Session in if, as if it had not.

Answer 1

You have to put a condition for when enter it check if the Session exists, try:

if(isset($_SESSION['login']))

will probably solve

Answer 2

The correct is to check the isset and then compare the string

if(isset($_SESSION['login']) && $_SESSION['login'] == 'admin')
{
   echo "logado";
}
