php - How to keep a session alive after logging in (Codeigniter) -

-

we building webshop based on codeigniter. products saved in shopping cart of codeigniters' cart class.

when visitor logs in it's account, products in cart removed because new session started when user logged in.

how can keep products in cart @ point?

if($query->num_rows() == 1)     {         $user = $query->row_array();         $data = array(                 'userid' => $user['id'],                 'email' => $user['email'],                 'validated' => true                 );         $this->session->set_userdata($data);          return true;     }

you have create new table in base, shoppingcarts, , pass items chart class in table, , user id, when user log in query table id , id of row got products.but when user bye delete rows in base , unset cart class

  $data = array(                    'id'      => 'sku_123abc',                    'qty'     => 1,                    'price'   => 39.95,                    'name'    => 't-shirt',                    'options' => array('size' => 'l', 'color' => 'red'                    'user_id  => '45')                 );      $this->cart->insert($data);     $chart = $this->cart->contents();     $this->db->insert('shoppingcarts',$chart);

this simple example, how :)

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
