php - 在 Codeigniter 中将重复值插入数据库

Question

我正在将一些数据插入到我的 Codeigniter Controller 的数据库中

 function addsoothingmemory() {
        $config['upload_path'] = './uploads2/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '500000';
        $config['max_width'] = '100024';
        $config['max_height'] = '100768';

        $this->upload->initialize($config);

        if (!$this->upload->do_upload()) {
            $error = array('error' => $this->upload->display_errors());

            $this->load->view('soothing', $error);
        } else {

            $imagedata = $this->upload->data();

            $data = array(
                'image_path' => $imagedata['file_name'],
                'title' => $this->input->post('title'),
                'user_id' => $this->session->userdata("user_id"),
                'feelingrate' => $this->session->userdata("feelingrate"),
                'description' => $this->input->post('description')
            );

            $query = $this->favourite_db->getsoothingcount() + 1;
            $this->favourite_db->add_soothingmemory($data);
            $count = array('soothingcount' => $query);
            $this->favourite_db->updateusercount($count);
            $this->load->view('positivepast', $data);
        }
    }

型号

function add_soothingmemory($data) {
    $this->load->database();
    $this->db->insert('soothingmemory', $data);
    $this->set_session();
    return $data;
}

问题是，当将值插入数据库时​​，它会插入三次，从而创建多个/重复的行。

我也遇到了同样的问题，

无论如何，在你的模型中，

$this->db->limit(1);
$this->db->insert('soothingmemory', $data);

这样就可以避免重复。 希望对您有帮助
