我开始尝试打开购物车,我尝试在面板管理中构建子菜单,文件名为 item.php,我只是尝试插入到数据库(head_text_field、title_text_field 和 max)&(表是 show_product),我尝试按照insert data into database with codeigniter , 但还是报错, error is Call to undefined method DB::insert() model\item\item.php
编辑第 1 部分:当我在模型中删除此代码时:
return $this->db->insert('show_product', $data);
并更改此代码:
$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']) . "'");
它可以工作,但数据库中仍然是空的???
这是 (controller/item/item.php) 中的 Controller
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['product'])){ // product have array in view e.g <input name=product[]>
$product = $this->request->get['product'];
$products = array();
foreach($product as $p)
{
$products[] = array($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

);
// 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['cancel'] = $this->url->link('item/item', 'token=' . $this->session->data['token'], 'SSL');
$this->data['action'] = $this->url->link('item/item/insert', 'token=' . $this->session->data['token'], 'SSL');
$this->template = 'item/item.tpl';
$this->children = array(

'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()) {
$this->model_item_item->insert_head($data);
$this->session->data['success'] = $this->language->get('text_success');
$url = '';
$this->redirect($this->url->link('item/item', 'token=' . $this->session->data['token'] . $url, 'SSL'));
}
}
protected function validateForm() {
if (!$this->user->hasPermission('modify', 'catalog/product')) {
$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;
}
}
}
这是模型 (model\item\item.php)
class ModelItemItem extends Model {
public function insert_head()
{
$head_text_field = $this->get['head_text_field'];
$title_text_field = $this->get['title_text_field'];
$max = $this->get['max'];
$data = array(
'head_text_field' => $head_text_field,
'title_text_field' => $title_text_field,
'max' => $max
);
return $this->db->insert('show_product', $data);
//$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']) . "'");
}
}
最佳答案
您的查询不应该像这样:
$this->db->query("INSERT INTO .... ");
我不认为 opencart 是基于 codeigniter 构建的,尽管我听说它的一些类是相似的
尝试在查询的开头添加一些空格:
$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']) . "'");
你的 insert() 函数需要
$this->model_item_item->insert_head($data); //wrong
更改为:
$this->model_item_item->insert_head($this->request->post);
你的模型应该是这样的:
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']) . "'");
}
