我刚刚看到opencart的一些扩展，从产品列表页面更新了产品，我尝试了我的opencart项目，有趣...现在我开始为我的opencart项目开发一个新的扩展， ：将批量产品插入管理员...这一次最多可以添加10个产品，填写产品表单后点击保存按钮这10个产品可以存储到数据库...每个产品只能形成5个在表单字段之后，
我可以使用opencart默认产品编辑页面稍后添加额外的详细信息/选项/说明，当插入此批量产品时，只有3个以下表格连接我的查询，
我尝试了一些代码，我的问题是当我点击保存按钮表product和product_description数据插入功能成功，但product_id并非这两个表都是唯一的，例如product表product_id = 125然后product_description表product_id = 5，我需要这3个表 product_id 必须与我们默认的opencart插入工作一样唯一...任何想法.. ??
我在这里尝试了...... 的表格
<input type="text" name="product_description[<?php echo $language['language_id']; ?>][name]" value="<?php echo isset($product_description[$language['language_id']]) ? $product_description[$language['language_id']]['name'] : ''; ?>" />
<input type="text" name="model" value="" />
<input type="text" name="quantity" value="" />
<input type="text" name="price" value="" />
<select name="stock_status_id">
<?php foreach ($stock_statuses as $stock_status) { ?>
<?php if ($stock_status['stock_status_id'] == $stock_status_id) { ?>
<option value="<?php echo $stock_status['stock_status_id']; ?>" selected="selected"><?php echo $stock_status['name']; ?></option>
<?php } else { ?>
<option value="<?php echo $stock_status['stock_status_id']; ?>"><?php echo $stock_status['name']; ?></option>
<?php } ?>
<?php } ?>
</select>
控制器
public function simple_pu() {
$this->load->language('catalog/product');
$this->document->setTitle($this->language->get('heading_title'));
$this->load->model('catalog/product');
if (isset($this->request->post['selected']) && $this->validateSimplePu()) {
$url = '';
foreach ($this->request->post['selected'] as $product_id) {
$price_str = $product_id.'_price';
$quantity_str = $product_id.'_quantity';
$model_str = $product_id.'_model';
$name_str = $product_id.'_name';
$status_str = $product_id.'_status';
$price = $this->request->post[$price_str];
$quantity = $this->request->post[$quantity_str];
$model = $this->request->post[$model_str];
$name = $this->request->post[$name_str];
$status = $this->request->post[$status_str];
$su_data = array('price' => $price, 'quantity' => $quantity, 'model' => $model, 'name' => $name, 'status' => $status);
$this->model_catalog_product->editPrices($product_id, $su_data);
}
$this->redirect($this->url->link('catalog/product', 'token=' . $this->session->data['token'] . $url, 'SSL'));
}
$this->getListbulk();
}
模型
public function addBulkproduct($product_id, $su_data) {
if (isset($su_data['product'])) {
$this->db->query("INSERT INTO " . DB_PREFIX . "product SET price = '" . $this->db->escape($su_data['price']) . "', model = '" . $this->db->escape($su_data['model']) . "', quantity = '" . $this->db->escape($su_data['quantity']) . "', student_id = '" . (int)$student_id . "', date_added = NOW()");
}
if (isset($su_data['product_description'])) {
$this->db->query("UPDATE " . DB_PREFIX . "product_description SET name = '" . $this->db->escape($su_data['name']) . "' WHERE product_id = '" . (int)$product_id . "'");
}
}
那就是.... 上面的代码只有一个结构如果你知道任何与我的问题有关的扩展，你可以建议我......
感谢...

您必须更新您的型号。检查/admin/model/catalog/product.php和方法addProduct() - 插入产品后，您必须检索$product_id，因此在您的模型中应该是这样的：
public function addBulkproduct($su_data) {
if (isset($su_data['product'])) {
$this->db->query("INSERT INTO " . DB_PREFIX . "product SET price = '" . $this->db->escape($su_data['price']) . "', model = '" . $this->db->escape($su_data['model']) . "', quantity = '" . $this->db->escape($su_data['quantity']) . "', student_id = '" . (int)$student_id . "', date_added = NOW()");
$product_id = $this->db->getLastId();
// INSERT INTO PRODUCT TO STORE
$this->db->query("INSERT INTO " . DB_PREFIX . "product_store (store_id, product_id) SELECT store_id, " . (int)$product_id . " FROM " . DB_PREFIX . "store");
if (isset($su_data['product_description'])) {
$this->db->query("INSERT INTO " . DB_PREFIX . "product_description SET name = '" . $this->db->escape($su_data['name']) . "', product_id = '" . (int)$product_id . "'");
}
}
}
请注意，您不再将$product_id作为方法参数传递 - 插入产品，生成新ID，并为此ID存储说明。此外，产品说明不会更新，但也会以新的形式插入！只有在插入产品时才会存储产品描述 - 即使没有产品数据，也无法存储产品描述......
您也应该为产品说明行设置language_id。
