If you are using CI Session be aware because you are going to save data into a cookie and this can hold only 4KB:

Use CodeIgniter database Sessions.

While I've extended my cart class to use $_SESSION, there's nothing in the cart class that would keep you limited to 7 items. It is your code, which you should share so we can help.

Hi, InsiteFX.. Are there any other solution beside using database session? eg. change the limit more than 4Kb. I think 4Kb can hold much data, but I dont know why my cart only hold 7 items
here is my code :
$product_id = $this->input->post("input_product_id");
$size_id = $this->input->post("input_size_id");
$color_id = $this->input->post("input_color_id");
$qty = $this->input->post("input_qty");
$production_code = $this->Mproduct->get_production_code_detail($product_id, $size_id, $color_id);
$data = array(
'id' => $production_code->production_code,
'qty' => $qty,
'price' => $production_code->price,
'name' => $production_code->name,
'options' => array('size' => $production_code->size, 'color' => $production_code->color)
);
$this->cart->insert($data);

The 4Kb limit is a hard limit, set by the browser. You can't do anything about it.
Remember that data is stored in the cookie as serialized array, which is then encrypted. Both actions will increase the amount of data sent to the browser. You'll get to 4Kb quite quickly.
If you don't want to use database sessions (why not?), you could use the native sessions library, which uses PHP's standard sessions. Note that on shared hosts, this is not secure.

Hi WanWizard, thanks for your advise, but finally I choose to use database session.. hehe..
I just dont know that 4Kb is set by the browser
, I think it set by CI. because of that I ask the other solution but I think save the session on database is the good solution now.
thanks for the help all.

The 4Kb Cookie is set by the web browser there is nothing that you can do
about! It has nothing to do with CI.

This is not entirely true. The session_save_path() function can set the location of the session data to anywhere, and if you choose a location within your exclusive hosting account but above what is publicly accessible, then as far as I'm concerned this is secure. Am I wrong?

Some hosters allow you to do that, some don't. If you can store session files within your personal disk space, than it is more secure (taking the assumption that those who can access your part of the disk can also access your database).
