Fetch data in a selected table row

#1
Exclamation 
Hello,

I'm trying to edit the data inside a table row. I'm using a contextmenu not a button, when I tried to click an item like edit/delete a modal will appear for the data to be edited. I successfully retrieve the data inside a table row the problem is that it will always fetch the last data in the row. I wanted to edit in a selected row. I tried the button it works but in the contextmenu, I can't edit a selected row.

Table:
Code:
<div class="container">
     <div class="row">
       <div class="col-md-12">
         <div class="table-responsive">
           <table id="ppmpsupplies" class="table table-bordered table-hover" cellspacing="0" width="100%">
             <thead>
               <tr>
                 <th>Code</th>
                 <th>General Description</th>
                 <th>Unit</th>
                 <th>Quantity</th>
                 <th>Estimated Budget</th>
                 <th>Mode of Procurement</th>
                 <th>Actions</th>
               </tr>
             </thead>
             <tbody>
               <?php foreach($items as $item){?>
               <tr>
                 <td>
                   <?php echo $item->id;?>
                 </td>
                 <td>
                   <?php echo $item->description;?>
                 </td>
                 <td>
                   <?php echo $item->unit;?>

                 </td>
                 <td>
                   <?php echo $item->budget;?>
                 </td>
                 <td>
                   <?php echo $item->mode;?>
                 </td>

                 <td>
                   <button class="btn btn-warning" onclick="edit_item(<?php echo $item->id;?>)"><i class="glyphicon glyphicon-pencil"></i></button>
                   <button class="btn btn-danger" onclick="delete_item(<?php echo $item->id;?>)"><i class="glyphicon glyphicon-remove"></i></button>
                 </td>
               </tr>
               <?php }?>

             </tbody>
             <tfoot>
               <td colspan="3"></td>
               <td>Total</td>
               <td></td>
             </tfoot>
           </table>
         </div>
       </div>
     </div>
   </div>

Contextmenu:
Code:
"edit": {
        name: "Edit",
        icon: "fa-pencil-square-o",
        callback: function(itemKey, options) {        
        $('#ppmpsupplies').on('click', 'tr', edit_item( <?php echo $item->id ?> ));                                
        return true;
        }
        },
Script:
Code:
     function edit_item(id) {
       save_method = 'update';
       $('#gcjform')[0].reset();
       $.ajax({
         url: "<?php echo base_url('ppmp/ajax_edit/')?>" + id,
         type: "GET",
         dataType: "JSON",
         success: function(data) {

           $('[name="id"]').val(data.id);
           $('[name="description"]').val(data.description);
           $('[name="unit"]').val(data.unit);
           $('[name="quantity"]').val(data.quantity);
           $('[name="budget"]').val(data.budget);
           $('[name="mode"]').val(data.mode);

           $('#gcjmodal').iziModal('open');
         },
         error: function(jqXHR, textStatus, errorThrown) {
           alert('Error get data from ajax');
         }
       });
     }
Controller:
Code:
public function ajax_edit($id)
    {
        $data = $this->ppmp_model->get_by_id($id);
        echo json_encode($data);
    }
Model:
Code:
public function get_by_id($id)
    {
        $this->db->from($this->table);
        $this->db->where('id',$id);
        $query = $this->db->get();

        return $query->row();
    }

Does anybody know how to fix my problem?

Note: I added the full code by jsfiddle

Sir, this is the exact link of the library https://swisnl.github.io/jQuery-contextM...ement.html. I'm struggling with this now. I'm just studying web development.

Sir, the edit in the contextMenu can only edit one value at a time while the delete can either delete one or multiple values. But for now Im still stock in the Edit functionalities.

The Table:
PHP Code:
<table id="ppmpsupplies" class="table table-bordered table-hover" cellspacing="0" width="100%">
 <
thead>
 <
tr>
 <
th>Code</th>
 <
th>General Description</th>
 <
th>Unit</th>
 <
th>Quantity</th>
 <
th>Estimated Budget</th>
 <
th>Mode of Procurement</th>
 <
th>Actions</th>
 </
tr>
 </
thead>
 <
tbody>
 <?
php foreach ($items as $item): ?>
 <tr data-id="<?= $item->id ?>">
 <td><?= $item->id?></td>
 <td><?= $item->description?></td>
 <td><?= $item->unit?></td>
 <td><?= $item->quantity?></td>
 <td><?= $item->budget?></td>
 <td><?= $item->mode?></td>
 <td>
 <button class="btn btn-warning" onclick="edit_item(<?php echo $item->id?>)"><i
 class="glyphicon glyphicon-pencil"></i></button>
 <button class="btn btn-danger" onclick="delete_item(<?php echo $item->id?>)"><i
 class="glyphicon glyphicon-remove"></i></button>
 </td>
 </tr>
 <?php endforeach; ?>
 </tbody>
 <tfoot>
 <td colspan="3"></td>
 <td>Total</td>
 <td></td>
 </tfoot>
</table> 

data- is a custom attribute. I added data-id to the tr.

Code:
"edit": {
name: "Edit",
icon: "fa-pencil-square-o",
callback: function (itemKey, options) {
               var id = $(this).closest('tr').data('id');
               edit_item(id);
}
}
}

if you delete an item, you do not need to reload.
You can use .closest('tr').remove()

eg.
Code:
$( "#ppmpsupplies tbody" ).on( "click", "tr button.btn-danger", function() {
   alert($(this).closest('tr').data('id'));
   $(this).closest('tr').remove();
});

or

Code:
/*
onclick="delete_item(this,<?php echo $item->id; ?>)"
*/
function delete_item(element, id) {
   alert($(element).closest('tr').data('id'));
   $(element).closest('tr').remove();
}
The ajax code is necessary. the example should show how to use closest and remove Smile

Sir, 

I got an error undefined. When I try the delete function. I try fixing but still I got that error. I already remove the button I just wanted to used the context menu.


Code:
"delete": {
                           name: "Delete",
                           icon: "fa-trash-o",
                           callback: function(item, id) {
                              var id = $(this).closest('tr').data('id');
                               delete_item(id);
                               return true;
                           }
                       },

Code:
function delete_item(element, id) {
       // if(confirm('Are you sure delete this data?'))
       // if(toastr.success('successfully deleted :)', 'Success Alert', {timeOut: 5000}))
       alert($(element).closest('tr').data('id'));
       $(element).closest('tr').remove();
       {
         
           $.ajax({
               url: "<?php echo site_url('ppmp/delete_item')?>/" + id,
               type: "POST",
               dataType: "JSON",
               success: function(data) {
                   // location.reload();
               },
               error: function(jqXHR, textStatus, errorThrown) {
                   alert('Error deleting data');
               }
           });

       }
   }
