Question

来自UIKit，我只是在尝试SwiftUI。

我只是想在带有导航栏的视图中显示世界。所以我写了下面的代码。

我可以看到Text小部件，但看不到NavigationView小部件。

var body: some View {
    NavigationView {
      VStack(alignment: .center) {
        Text("Hello World")
      }
    }
    .navigationBarTitle(Text("ForgotPassword")
    .font(.largeTitle)
    .fontWeight(.medium), displayMode: .inline)
    .shadow(color: Color.blue, radius: 0, x: 0, y: 5)
    .navigationViewStyle(DefaultNavigationViewStyle())
    .background(Color.red)
  }

我在这里做错什么了吗？

尝试一下：

$ftp_server = "myserver";
$ftp_user_name = "myuser";
$ftp_user_pass = "mypass";

$source_file = $_FILES['file']['tmp_name'];
$fileType = $_FILES['file']['type'];

/*get file extension [*/
  $fileExt = pathinfo($_FILES["file"]["name"], PATHINFO_EXTENSION);
  $fileExt = strtolower($fileExt);
/* ] */

$destination_folder = "/public_html/wp/wp-content/plugins/AbonneerProgrammas/FilesUpload";
$destination_file = $destination_folder . "/" . basename($_FILES['file']['name']);

$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); 
ftp_pasv($conn_id, true); 

$allowed = array('zip', 'rar');

/*use $extension variable to check allowed or not [*/
if(in_array($fileExt, $allowed)) {

//my upload code

}else {
    echo "U mag dit type bestand niet uploaden.";
}
/* ] */
