+"<td><button>X</button></td></tr>");
}

in view dynamically new rows are added

But in controller

But it doesn't go to the if(isset($_POST['Detail']) condition Help me plz.......

Answer 1

First of all use isset() and not isset[) and are you posting with method POST or GET?

if(isset($_POST['Detail'])) {
  var_dump($_POST['Detail'];
}

if(!isset($_POST['Detail']) && isset($_GET['Detail'])) {
  echo 'Form method is wrong, GET is used by default not POST';
}

Answer 2

因为您应该检查if(isset[$_POST['Detail']))

Answer 3

If you are submitting form using Jquery. then use following code for submitting dynamically added elements

$('#buttonSubmit').on('click', 'button', function(){
    // do something
});
