我正在尝试通过控制器定义MySQL(model.php)值
这里是MySQL的代码
$this->db->query("INSERT INTO " . DB_PREFIX . "cart_to_customer SET customer_id = '" . (int)$this->customer->getId() . "', cart_id = '" . (int)$data['cart_id'] . "'");
我只想通过controller.php插入cart_id值
例如
$data['cart_id'] = '45';
我尝试使用view.tpl的输入尝试以下内容,并且工作正常,但是当存在null值时,它必须在其中插入45,但给出0。
if (isset($this->request->post['cart_id'])) {
$data['cart_id'] = $this->request->post['cart_id'];
} else {
$data['cart_id'] = '45';
}
我如何从控制器设置值?
请指导如何...假设您有控制器文件catalog/controller/extension/module/your_estension.php
和与此控制器文件相对应的模型文件。.catalog/model/extension/module/your_estension.php
。在您的控制器文件中:
// you must load model file like this:
$this->load->model('extension/module/your_estension');
if (isset($this->request->post['cart_id'])) {
$data['cart_id'] = $this->request->post['cart_id'];
} else {
$data['cart_id'] = '45';
}
//next you can send your posted data to the model...
$this->model_extension_module_your_estension->addCardId($data['cart_id']);
// next in the corresponding model file you can retrieve that data:
public function addCardId($card_id) {
// and write it to DB
$this->db->query("INSERT INTO " . DB_PREFIX . "cart_to_customer SET customer_id = '" . (int)$this->customer->getId() . "', cart_id = '" . (int)$card_id . "'");
}
