如何在opencart中将数组插入数据库？

Question

我通过添加行表构建动态输入，通过自动完成构建用户输入，然后我将 PRODUCT_ID 存储在 <input name="idp" value="">

例如用户输入两次（惠普和电脑）

产品名称 | PRODUCT_ID

1. 生命值 = 2945

2. 计算机 = 8654

应该在数组中是 = (2945,8654)

这是给控制器的：

class ControllerItemItem extends Controller { //Controller/Item/Item.php
private $error = array(); 
 
public function index() {
    $this->language->load('item/item');
    
    $this->document->setTitle($this->language->get('heading_title')); 
    
    $this->load->model('item/item');
    
    $this->getList();
}

protected function getList(){
    
    if (isset($this->request->get['head_text_field'])){
        $head_text_field = $this->request->get['head_text_field'];
    } else {
        $head_text_field = null;
    }
    
    if (isset($this->request->get['title_text_field'])){
        $title_text_field = $this->request->get['title_text_field'];
    } else {
        $title_text_field = null;
    }
    
    if (isset($this->request->get['max'])){
        $max = $this->request->get['max'];
    } else {
        $max = null;
    }
    
    if(isset($this->request->get['idp'])){ 
        $product = $this->request->get['idp'];
        $product2 = array();
        foreach($product as $p)
        {
            $product2[] = $p;
        }

    }else {
        $product = null;
    }
    
    
    // BREADCRUMBS //
    $this->data['breadcrumbs'] = array();

    $this->data['breadcrumbs'][] = array(
        'text'      => $this->language->get('text_home'),
        'href'      => $this->url->link('common/home', 'token=' . $this->session->data['token'], 'SSL'),
        'separator' => false
    );

    $this->data['breadcrumbs'][] = array(
        'text'      => $this->language->get('text_module'),
        'href'      => $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL'),
        'separator' => ' :: '
    );

    $this->data['breadcrumbs'][] = array(
        'text'      => $this->language->get('heading_title'),
        'href'      => $this->url->link('module/item', 'token=' . $this->session->data['token'], 'SSL'),
        'separator' => ' :: '
    );
    // END //
    
    // Call Language //
    $this->data['heading_title'] = $this->language->get('heading_title');
    $this->data['entry_head'] = $this->language->get('entry_head');
    $this->data['entry_title'] = $this->language->get('entry_title');
    $this->data['entry_product'] = $this->language->get('entry_product');
    $this->data['entry_max_item'] = $this->language->get('entry_max_item');
    $this->data['button_save'] = $this->language->get('button_save');
    $this->data['button_cancel'] = $this->language->get('button_cancel');
    // END //
    
    $this->data['cancel'] = $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL');
    $this->data['action'] = $this->url->link('item/item/insert', 'token=' . $this->session->data['token'], 'SSL');
    $this->data['token'] = $this->session->data['token'];

    
    $data   =   array(
        'head_text_field'   =>  $head_text_field,
        'title_text_field'  =>  $title_text_field,
        'max'               =>  $max
    );
    
    $this->template = 'item/item.tpl';
    $this->children = array(
        'common/header',
        'common/footer'
    );
    
    $this->response->setOutput($this->render());
        
}

public function insert()
{
    
    $this->language->load('item/item');
    
    $this->document->setTitle($this->language->get('heading_title')); 
    
    $this->load->model('item/item');
    
    if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validateForm()) {
        //$this->model_item_item->insert_head($this->request->post);
        $this->model_item_item->insert_detail($this->request->post);
        
        //$this->session->data['success'] = $this->language->get('text_success');
        //$this->redirect($this->url->link('item/item', 'token=' . $this->session->data['token'], 'SSL'));
    }
}

protected function validateForm() {
    if (!$this->user->hasPermission('modify', 'item/item')) {
        $this->error['warning'] = $this->language->get('error_permission');
    }

    if ((utf8_strlen($this->request->post['head_text_field']) < 1) || (utf8_strlen($this->request->post['head_text_field']) > 64)) {
        $this->error['head'] = $this->language->get('error_head');
    }
    
    if (!$this->request->post['title_text_field']) {
        $this->error['title'] = $this->language->get('error_title');
    }
                
    if (!$this->error) {
        return true;
    } else {
        return false;
    }
}

这是给模特的：

class ModelItemItem extends Model { 
public function insert_head($data)
{
    $this->db->query("INSERT INTO " . DB_PREFIX . "show_product SET head_text = '" . $this->db->escape($data['head_text_field']) . "', title_text = '" . $this->db->escape($data['title_text_field']) . "', max_item = '" . $this->db->escape($data['max']) . "'");
}

public function insert_detail($product2)
{
    foreach($product2 as $detail)
    {
        //$this->db->query("INSERT INTO " . DB_PREFIX . "show_product_detail SET product_id = '". $this->db->escape($detail['product']) . "'");
    }
    echo $detail[0];
}

}

这是为了查看：

    <?php echo $header; ?>
<div id="content">
  <div class="breadcrumb">
    <?php foreach ($breadcrumbs as $breadcrumb) { ?>
    <?php echo $breadcrumb['separator']; ?><a href="<?php echo $breadcrumb['href']; ?>"><?php echo $breadcrumb['text']; ?></a>

当我尝试向我的数据库插入查询时，值只有 1 个数字。

然后我尝试 Echo 以确保变量正确但它是错误的，结果是最后一个用户输入（计算机，在数组（8,6,5,4）中）？应该是 (2945,8654) 而不是 (8,6,5,4)？

有人可以帮我解决这个问题吗？我已经尝试解决这个问题 1 周仍然没有希望:(

如果要在database 中插入array variables，首先需要对它们进行编码，然后再插入它们。

例如。 $abc = 数组（3,45,6,78,89）;

查询："INSERT INTO " . DB_PREFIX . "show_product_detail SET product_id = '". $this->db->escape(json_encode($abc)) . "'
