我的第一个问题是将我的图像上传到我的路径目录中，而另一个是将其保存在我的数据库中
所以这是我的控制器" dash.php"
function add(){
$this->form_validation->set_rules('book_title', 'trim|required|xss_clean');
$config['upload_path'] = './assets/img/';
$config['allowed_types'] = 'jpg|png|gif';
$this->load->library('upload', $config);
if(!$this->form_validation->run() && !$this->upload->do_upload()){
//load dash
$this->load->model('Books_model_admin');
$results = $this->Books_model_admin->search('', '');
$data['num_req'] = $results['num_request'];
$this->load->model('Reserve_display_model');
$results = $this->Reserve_display_model->active('', '');
$data['num_request1'] = $results['num_request1'];
//display number of mess
$this->load->model('Message_model');
$results = $this->Message_model->get_list_mess('', '');
$data['mess_results'] = $results['mess_row'];
$this->load->view('content/admin_header', $data);
$this->load->view('content/admin_add');
$this->load->view('content/admin_footer');
} else {
$data->image_name = $this->input->post('image_name');
$data->book_title = $this->input->post('book_title');
$data->book_author = $this->input->post('book_author');
$data->book_status = $this->input->post('book_status');
$data->book_publisher = $this->input->post('book_publisher');
$data->book_date_published = $this->input->post('book_date_published');
$data->book_issue = $this->input->post('book_issue');
$data->book_isbn = $this->input->post('book_isbn');
$file_data = $this->upload->data('file_name');
$data->image = base_url().'assets/img/'.$file_data['file_'];
if($this->crud_model->create_data($data)){
$this->session->set_flashdata('list_created', 'The book has been added successfully');
//redirect to dash with error above
redirect('dash');
}
}
}
这是我的模型" crud_model.php"
function create_data($data){
$insert = $this->db->insert('book_list', $data);
return $insert;
}
这是我的视图" admin_add"

在数据库中使用路径目录保存图像名称时，而不是保存图像名称，我像http：//http：//localhost/system/system/assets/img/array一样，我得到的"数组"，我应该得到的是此http：//localhost/system/assets/img/imagename.jpg
，另一个是我无法将其保存在我拥有的路径目录中。
-
确保您在查看页面中使用
<form>属性enctype="multipart/form-data"。 -
确保您的上传路径有效并且
base_url()定义正确。
从我的角度来看，上述控制器代码没有错误。
检查，让我知道
