<br>
<button type="button" onClick="update_cart();">Update Chart</button>
<button type="button">Clear All</button>
and this is my controller update cart
// Update Product from Cart
function update(){
$cart = $this->cart->contents();
$data = array(
(foreach ($cart as $c)){
array(
'rowid' => $c['rowid'],
'qty' => $this->input->post('qty'),
),
};
);
echo "<pre>";
print_r($data);
//$this->cart->update($data);
//redirect('cart/show');
}
what I want to ask is:
1. How to update all of the items in the cart CodeIgniter?
2. Or how to insert function "foreach" in "array" as in update function?

Answer 1

I will suggest to send the value of rowid and quantity from your form to the update function .
<form action="" method="POST">
<input type="text" name="quantity" value="" />
<input type = "hidden" name="rowid" value=""/>
<!-- OTHER FORM FIELDS HERE -->
<input type="submit" name="submit" value="UPDATE" />
</form>
And in your controller.
public function update()
{
$data=$this->cart->update(array(
'rowid'=>$this->input->post('rowid'),
'qty'=> $this->input->post('quantity');
));
$this->cart->update($data);
//redirect here
}
Update
To update all row at once you can use multidimensional array . It is well defined in userguide
$data = array(
array(
'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
'qty' => 3
),
array(
'rowid' => 'xw82g9q3r495893iajdh473990rikw23',
'qty' => 4
),
array(
'rowid' => 'fh4kdkkkaoe30njgoe92rkdkkobec333',
'qty' => 2
)
);
$this->cart->update($data);
