Pass PHP variable to bootstrap modal

I have a button that is created using a while loop. so the while loop creates a table row for each row in a mysql table.

I have one line of code for the button which is created again for each row of the table and each button has a different value based on the id for that record.

$order .= '<td><a href="#myModal" class="btn btn-default btn-small" id="custId" data-toggle="modal" data-id="'.$row['ID'].'">Edit</a></td>';

The problem is that I want to use that $row['ID'] and view it in a modal so I can retrieve the record with the same ID using mysqli query.

Here is the code for the modal.

<div class="modal fade" id="myModal" role="dialog">
        <div class="modal-dialog">
            <!-- Modal content-->
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal">&times;</button>
                    <h4 class="modal-title">Edit Data</h4>
                </div>
                <div class="modal-body">
                    i want to save the id in a variable here so i can use it in a php script for this modal
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>

adding the modal in a loop is auto duplicating the html content when it is not really necessary! it is not a good practice to add a modal to each item in a loop instead call the data only when it is requested!

here is an example add the following button to a loop in php

<button data-id="<?php echo $note['id']; ?>"  onclick="$('#dataid').text($(this).data('id')); $('#showmodal').modal('show');">Click me </button>

on your modal you can know use that id to make a request to your db or any json

example assuming you are using a modal called showmodal use this info to make a new request to your database or desire class or function!

<?php $dataid = '<span id="dataid"/>'; echo $dataid; ?>

The echo $dataid is only to show you that the id of the clicked item in the loop really works.

as you can see here we are only adding 1 single html template in the loop and we are also only calling data when it is being requested! this will save memory and also will be faster.

I hope this helps many people

put this inside your loop

<button type="button" class="btn btn-success" data-toggle="modal" data-target="#message<?php echo $row['id'];?>">Message</button>

<div id="message<?php echo $row['id'];?>" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <?php echo $row['id'];?>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

If, I got you correct.

The modal trigger button with $row['ID']

$order .= '<td><a href="#myModal" class="btn btn-default btn-small" id="custId" data-toggle="modal" data-id="'.$row['ID'].'">Edit</a></td>';

Bootstrap Modal event to fetch the $row['ID'] value with Ajax method

$(document).ready(function(){
    $('#myModal').on('show.bs.modal', function (e) {
        var rowid = $(e.relatedTarget).data('id');
        $.ajax({
            type : 'post',
            url : 'fetch_record.php', //Here you will fetch records 
            data :  'rowid='+ rowid, //Pass $id
            success : function(data){
            $('.fetched-data').html(data);//Show fetched data from database
            }
        });
     });
});

Modal HTML

<div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Edit Data</h4>
            </div>
            <div class="modal-body">
                <div class="fetched-data"></div> //Here Will show the Data
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

Last Create fetch_record.php, retrieve the record and show in modal

<?php
//Include database connection
if($_POST['rowid']) {
    $id = $_POST['rowid']; //escape string
    // Run the Query
    // Fetch Records
    // Echo the data you want to show in modal
 }
?>
