How to submit the dynamical input field into the database?

问题

I am displaying the input field dynamically which is working for me.

The issue is,

I have to submit the form. I have tried some code as below but it's not working.

I am using Codeigniter.

Controler code

public function register(){
$save = array(
   'pp_fileStatus' => $this->input->post('pp_fileStatus');
   'reasonDate' => $this->input->post('reasonDate');
   'reasonAmt' => $this->input->post('reasonAmt');
 );
$afterxss=$this->security->xss_clean($save);
        if ($afterxss) 
        { 
          $this->db->insert('tbl_register',$afterxss);
            $response['error'] = "true";
            $response['msg']   = "Successfully";

      }else{
          $response['error'] = "false";
          $response['msg']   = "Sometning wrong! please check the internet connection and try again";
      } 
   echo json_encode($response);          
}

I am adding the field dynamically and incrementing the name. Please let me know what name I have to use here

$save = array(
       'pp_fileStatus' => $this->input->post('pp_fileStatus');
       'reasonDate' => $this->input->post('reasonDate');
       'reasonAmt' => $this->input->post('reasonAmt');
     );

Below is the code for adding the input field dynamically.

$(document).ready(function() {
  var maxField = 10; //Input fields increment limitation
  var x = 1; //Initial field counter is 1
  var count = 2;
  var numberIncr = 1; // used to increment the name for the inputs
  var addrm = '';

  //Once add button is clicked
  $(document).on('click', '#clicktoadd', function() {
    //Check maximum number of input fields
    if (x < maxField) {
      x++; //Increment field counter
      numberIncr++;
      $(".medication_info").append('<select name="pp_fileStatus' + numberIncr + '" class="form-control multipleselect pp_fileStatus dynamicVal"><option value="" disabled selected>Status</option><option value="1">Open</option><option value="2">Close</option><option value="3">Pending</option></select>');
    }
    count++;

  });
  $(document).on('change', '.pp_fileStatus', function(event) {

    if (($(this).val() == '1') || ($(this).val() == '3')) {
      $(".medication_info").append('<div class="addbankField input-wrapper padding0"><div class="form-group"> <input type="text" name="reasonDate' + numberIncr + '"  class="form-control datetimepicker dynamicVal" placeholder="Date"></div></div><div class="addbankField input-wrapper"><div class="form-group"> <input type="text" name="reasonAmt' + numberIncr + '"  class="form-control commnumber dynamicVal" placeholder="amt"></div></div><input type="hidden" name="remark' + numberIncr + '"  class="form-control" placeholder="Remark">');
    } else {
      $(".medication_info").append('<div class="addbankField input-wrapper lbpflex padding0"><div class="form-group"> <input type="text" name="reasonDate' + numberIncr + '"  class="form-control datetimepicker dynamicVal" placeholder="Date"></div></div><div class="addbankField input-wrapper"><div class="form-group"> <input type="text" name="remark' + numberIncr + '"  class="form-control dynamicVal" placeholder="Remark"></div></div><input type="hidden" name="reasonAmt' + numberIncr + '" class="form-control" placeholder="amt">');
    }
  });

});



$('#register').on('submit', function(event) {
  event.preventDefault();
  // adding rules for inputs with class 'comment'
  $('.dynamicVal').each(function() {
    $(this).rules("add", {
      required: true
    })
  });
  // test if form is valid 
  if ($('#register').validate().form()) {
    $.ajax({
      //url:"process.php",
      url: baseUrl + "/Customer_control/register",
      type: "POST",
      dataType: "json",
      data: $('#register').serialize(),

      success: function(data) {
        alert("success");
      },
    }); // AJAX Get Jquery statment
  }
  //alert('hellow');
});
$('#register').validate({
  errorPlacement: function(error, element) {
    if (element.is("select")) {
      error.insertAfter(element.parent());
    } else {
      error.insertAfter(element);
    }

  }
});

<div id="clicktoadd"><a href="javascript:void(0);" class="btn btn-bg">Add More</a></div>
<form action="#" method="post" id="register" name="register">
  <div class="row">
    <div class="medication_info">
    </div>
  </div>

  <input type="submit" name="send" value="submit">

Can anyone here to help me out with this issue?

回答1:

you need to create a function for your submit actions, which you call (make available) on document load and also with your change event, after having appended the DOM.

simplified example:

$(document).ready(function() {
  my_submit(); // enables your submit calls
  $(document).on('change', '.pp_fileStatus', function(event) {
    // your append code
    my_submit(); // again, enables your submit calls
  })
}
function my_submit(){
  $('#register').on('submit', function(event) {
    // your code
  })
  $('#register').validate({
    // your code
  })
}
