Session Variable.....................help!

[okuto1973]

Please someone could help me?

session_start();
$boolean=session_is_registered ($sess_numeroc);
echo "BOOLEAN=$boolean";

if ($boolean=="")
{
$n="a0";
echo "<br>sess_numeroc in session";

$sess_numeroc=$n;

session_register($sess_numeroc);

$sess_numeroc=$n;

$_SESSION['sess_numeroc'] = $n;

}

if ($add)
{
echo "<br>Add!";
$n=substr($sess_numeroc,1,strlen($sess_numeroc));
echo "N=$n";
$n=$n+1;
$sess_numeroc="a".$n;
session_register($sess_numeroc);

}

1-How to use number-variable in session?I have to add a "a"!
2-If i delete the command $_SESSION['sess_numeroc'] = $n;
the programas don't work,the variable don't be put in session.

I have php version 4.2.3
Someone know something more?

[keith73]

is session_numeroc a variable in the session?
If so, change
session_is_registered ($sess_numeroc)
to
session_is_registered ("sess_numeroc")

Also, the three lines checking for this value can be condensed into one expression.

if(session_is_registered("sess_numeroc")){
...
}

I don't know why you have to put an a in front of session vars.

The solution is not to go around mixing $session_var and $SESSION['session_var']. Drop this business about session_is_registered('varname') and use isset($SESSION['varname']) instead. Drop register_session($varname) and use $_SESSION['varname'] instead of $varname everywhere else.

Otherwise you just end up getting confused.

Also, if you use session_register('varname') after giving $varname a value, then any already-sessioned value of $varname will overwrite the value you just gave it. Solution: already given - don't use session_register().

Thax a lot!
My principal mistake was to use $VAR in session_register() instead of VAR only.
All now works!
Thanx again a lot!
