Question

我正在尝试使用codeigniter文件上传库上传多个图像，但即使选择了多个文件，它也只上传一个文件。请帮助

public CustomerDialog()
{
    InitializeComponent();
    nw = new northwindEntities(); 
}

private void CustomerDialog_Load(object sender, EventArgs e)
{
    dgvCustomer.DataSource = nw.Customers;
}

private void btnDelete_Click(object sender, EventArgs e)
{
    string strSelectedCustomerID = getSelectedCustomerID();
    Customer customer = nw.Customers.Where(a => a.CustomerID == strSelectedCustomerID).First();
    nw.Customers.DeleteObject(customer);
    nw.SaveChanges();
}

//the  new customer is persist on the database, but the dgvCustomer is not update.
private void btnAdd_Click(object sender, EventArgs e)
{
    Customer newCustomer = new Customer() { 
            CustomerID = txtCustomerID.Text,
             CompanyName = txtCompanyName.Text,
             ContactName = txtContactName.Text
        };
    nw.Customers.AddObject(newCustomer);
    nw.SaveChanges();

    dgvCustomer.DataSource = nw.Customers ;
    dgvCustomer.Refresh();
}

Answer 1

这可能有助于p_image是文件名

if (isset($_FILES['p_image']['name'])) {
                // total files //
                $count   = count($_FILES['p_image']['name']);
                // all uploads //
                $uploads = $_FILES['p_image'];

                for ($i = 0; $i < $count; $i++) {
                    if ($uploads['error'][$i] == 0) {
                        move_uploaded_file($uploads['tmp_name'][$i], 'uploads/product_cover/' . $uploads['name'][$i]);

                    }
                }
            }

foreach($_FILES as $key => $userfileObject)
            { 

                if ($this->upload->do_upload($key))
                {
                    $errors = $this->upload->display_errors();
                    flashMsg($errors);
                }
                else {
                // Code After Files Upload Success GOES HERE
                $data['content'] = 'success';
                $this->load->view('templates/template', $data);
                }`enter code here`


            }

Codeigniter仅上传一个图像而不是多个图像
