I have an array called config. I'm trying to echo a variable from the array in the session.
I've tried:
echo $this->session->userdata('config['item']');
but it doesn't work. What's wrong with my syntax here? I've print_r'd my session and the items are in the config array. I've also tried:
echo $this->session->userdata("config['item']");
I get no errors this time, but no data either.
If config is an array . And item is string name of what you want to get from config then
echo $this->session->userdata($config['item']);
or
echo $_SESSION[$config['item']];
If config is an array inside session you should first get it.
$tmp = $this->session->userdata('config');
echo $tmp['item'];
or
echo $_SESSION['config']['item']
Sorry for my english.
$abc = $this->session->userdata('datauser'); echo $abc['ID_NUM'];If you want to use the session array, use the variable, not the function:
echo $this->session->userdata['user_data']['item'];
If you want to write:
$this->session->userdata['user_data']['item'] = 'value';
$this->session->userdata['other_data']['other'] = 'value2';
$this->session->sess_write();
This allows you to edit values in array just like you do with $_SESION['user_data']['avatar'] = $avatar, with 'only' one extra line and only using CI library.
Always escape your string it should be this way:
echo $this->session->userdata('config[\'item\']');
