количество обновлений codeigniter не работает

Question

количество не обновляется только если я добавляю товар с одинаковыми параметрами более одного раза в мою корзину, он заменяет вместо увеличения количества существующего товара Это код просмотра корзины

`<table class="table table-bordered table-hover">

Работает нормально, когда добавляешь товар или меняешь его количество, все отлично работает, но если я добавляю товар с одинаковыми параметрами более одного раза в мою корзинувместо существующего элемента он заменяет

Answer 1

Проверьте, какой запрос генерируется, когда запрос на обновление срабатывает, я думаю, что любая цитата сигнала добавляется в ваш запрос.для проверки последнего запроса к базе данных используйте эту функцию: -
print_r ($ this-> db-> last_query ());

Answer 2

После долгих попыток я получаю свой код правильно, вот правильный код вставки и обновления

function add_cart_item_by_barcode(){

$product_code = $this->input->post('barcode', true);
$result = $this->order_model->validate_add_cart_item($product_code);

$rowid = $this->input->post('rowid');
$cart = $this->cart->contents();

foreach ($cart as $cart) {

       if($product_code == $cart['id']){

            $rowid=$cart['rowid'];
            $qty=$cart['qty'];


                    $data=array(
                    'rowid'=>$rowid,
                    'qty'=>$qty+1
                    );

        $data=$this->cart->update($data);
        $this->session->set_flashdata('cart_msg', 'add');
        redirect('admin/order/new_order/'.$flag ='add');

                    }
                }
if ($result) {  

// update rate
        $price = $this->check_product_rate($result->product_id, $qty=1);

        //product tax check
        $tax = $this->product_tax_calculate($result->tax_id, $qty=1, $price);

        $data = array(
            'id' => $result->product_code,
            'qty' => $qty,
            'price' => $price,
            'buying_price' => $result->buying_price,
            'name' => $result->product_name,
            'pkprice' => $result->p_price,
            'tax' => $tax,
            'price_option' => 'general'
        );
        $this->cart->insert($data);
        $this->session->set_flashdata('cart_msg', 'add');
}   

redirect('admin/order/new_order/'.$flag ='add');
                      }

Answer 3

Вы пробовали это?

<?php foreach ($this->cart->contents() as $items): ?>

<?php echo form_hidden($counter.'[rowid]', $items['rowid']); ?> // write this

, а затем это

<td><?php echo form_input(array('name' => $counter.'[qty]', 'value' => $items['qty'], 'maxlength' => '3', 'size' => '5')); ?></td>

вместо -

<?php echo form_input(array('name' =>'rowid1[]', 'type'=>'text', 'value' => $items['rowid'], 'maxlength' => '3', 'size' => '5')); ?>

Я надеюсь, что это работает
