Question

I am storing random stuff in my CI session such as a userID for example, and I have crawled up and down my code looking for the error, to then end up doing the sane thing and doing a var_dump / print_r on my session data.

So heres the thing. I do the print_r and i see the userID correctly in this case 21. But if I go one line directly below that print_r and do echo $this->session->userdata('userID'); my result is 2121 instead of 21, which is messing things all sorts of up for me, and I can’t find anything anywhere that mentions a similar problem so I am hoping someone here can set me straight.

edit to show “code”

print_r($this->session->userdata);
echo $this->session->userdata('userID');

which yields this result…

Array ( [userID] => 21 ) 21 

but if I do this..

//print_r($this->session->userdata);
echo $this->session->userdata('userID');

i get this as a result

2121 

hopefully this clears up the confusion some..

Answer 1

it seems like you’re outputting 21 someplace else
which is why you get 2121 and Array ( [userID] => 21 ) 21
do an exit();
right after echo $this->session->userdata('userID');
and you’ll see exactly what is stored there,
also var_dump() is a good idea.
