I have a form and it has text inputs and file input for upload an image. I tried to send values to my php page but i couldnt do it. Here is my ajax codes.
function sendval() {
  var form = $('#user_update_form')[0];
  var form_data = new FormData();
  $.ajax({
    type: 'POST',
    url: 'user_update.php',
    processData: false,
    data: form_data,
    success: function(msg) {
      $('#updtalert').html(msg);
    }
  });
}
