Edit PHP/AJAX to deal with DELETE OR EDIT -


first of before show code explain how webpage works.

  1. user selects date -> ajax calls on date change
  2. resulting php data displays in 2 sections on page.
  3. first section orders table contents
  4. second section items table contents (not including items inside orders)

what trying add functionality 3 buttons change tables dynamically using ajax. have working non ajax requests.

here code:

    $(document).ready(function(){         $('.date-picker').change(function(){             $.ajax({                  type: 'post',                  url: 'php/getproduct.php',                  data: {dateorderpicker: $('.date-picker').val()},                  datatype: 'json',                  success: function(data)                  {                     $("#cartrow").html(data.result_1);                     $("#otheritems").html(data.result_2);                  }              });          });      });

php file current ajax:

session_start();     include('db_config.php');     $datepicker = $_post['dateorderpicker'];      $sql = "select * orders deliverydate = ? , customerid = ? ";      $stmt = $conn->prepare($sql);     $stmt->bindparam(1, $datepicker, pdo::param_str);     $stmt->bindparam(2, $_session['customer_id'], pdo::param_int);     $stmt->execute();      $container = array();     $data['result_1'] = $data['result_2'] = '';     while ($row = $stmt->fetch(pdo::fetch_assoc))     {         $container[] = "'{$row['itemname']}'"; // put them inside temporary container         $data['result_1'] .= '             <div class="col-sm-4 col-md-4">                 <div class="content-boxes style-two top-column clearfix animated flipiny" style="opacity: 1;">                     <div class="content-boxes-text">                         <form action="php/edit.php" method="post" class="form-inline pull-right">                                 <h3>' . $row['itemname'] .

            }     }      echo json_encode($data);     exit;

both update , delete php file:

include('db_config.php');  if (isset($_post['update'])) { $qty = $_post['qty']; $id = $_post['id'];  echo $id;  $sql = "update orders set qty=? id=?"; $stmt = $conn->prepare($sql); $stmt->execute(array($qty,$id));  header('location: ../order.php'); } if (isset($_post['delete'])) { $id = $_post['id'];  $sql = "delete orders id=?"; $stmt = $conn->prepare($sql); $stmt->execute(array($id));  header('location: ../order.php'); }

the code above needs converted ajax, , both sections on page using ajax should update table automatically. might call first ajax query reload tables correctly?

thanks having @ this. having trouble wrapping head around how should work.

alex

it easy can give class (note : yes class ) update button , delete button

suppose update button has class "update_task"

but content added dom after dom loaded, need create 2 ajax request delegate methods delete , update.

for delegate reference - http://api.jquery.com/delegate/

// update

 $("body").delegate(".update_task","click",function(){    current_id = $(this).previous("input:hidden").val() // current update button id,        $.ajax({              type: 'post',              url: 'php/update_product.php',              data: {id: current_id, othervalues: other_value_of_choice},              datatype: 'json',              success: function(data)              {                 if(data==1)                {                    // ever want if data has been updated                }              }          });  });
