Pass PHP variable to bootstrap modal - php

Question

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>Edit</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">×</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>

Answer 1

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">×</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>Edit</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){
$('.fetched-data').html(data);//Show fetched data from database
}
});
});
});
Modal HTML
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Edit Data</h4>
</div>
<div class="modal-body">
<div class="fetched-data"></div> //Here Will show the Data
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
Last Create fetch_record.php, retrieve the record and show in modal
<?php
//Include database connection
if($_POST['rowid']) {
$id = $_POST['rowid']; //escape string
// Run the Query
// Fetch Records
// Echo the data you want to show in modal
}
?>

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
