Question

我收到以下错误：

遇到PHP错误

严重性：注意

消息：数组到字符串转换

文件名：models / Bulk_Recipeis_model.php

行号：32

我在模型中的代码：

public function insert_order($user, $recipies, $quantity, $date, $time, $totalbill)
{
    $this->db->trans_start();
    foreach($quantity as $key => $user_quantity) {
        $this->db->query("UPDATE bulk_delivery SET max_quantity = max_quantity - '$user_quantity'");
        $this->db->query("INSERT INTO bulk_delivery_order (id, user_quantity, date,time,total_bill,bulk_delivery_id) VALUES ('$user', '$user_quantity', '$date', '$time', '$totalbill', '$recipies')");
    }
    $this->db->trans_complete();
}

我在控制器中的代码：

public function get_insert_order(){
    $user = $this->userId;
    $recipies = $this->input->post('bulk_delivery');
    $quantity = $this->input->post('quantity');
    $date = $this->input->post('date');
    $time = $this->input->post('time');
    $totalbill = $this->input->post('bill');
    $this->bulk_recipe->insert_order($user, $recipies, $quantity, $date, $time, $totalbill);
    redirect('BulkRecipe_Controller');
}

在我看来，我使用的是数组数据：

<input type="hidden" name="bulk_delivery[]" value="<?php echo $row->bulk_delivery_id;?>" >
<input type="text" name="quantity[]" step="1" class="container" value="" onfocus="this.value = '';" onblur=";" style="width: 60px">

请告诉我如何解决此错误。

将您的模型更改为此 -

public function insert_order($user, $recipies, $quantity, $date, $time, $totalbill)
        {
            $this->db->trans_start();
            foreach($quantity as $key => $user_quantity) {
                $final_quantity = $user_quantity['key'];
                $this->db->query("UPDATE bulk_delivery SET max_quantity = max_quantity - '$final_quantity'");
                $this->db->query("INSERT INTO bulk_delivery_order (id, user_quantity, date,time,total_bill,bulk_delivery_id) VALUES ('$user', '$final_quantity', '$date', '$time', '$totalbill', '$recipies')");
            }
            $this->db->trans_complete();
        }
