Load DataTable data to a Edit Modal

I am trying to create an edit function for my data table. The data table is created using Yajra Data tables. Everything working fine unless when I try to load existing data into the edit modal it fails. No error is showing but the modal does not launch. I have only included a little portion of my code here for easy reference.
Modal:
<!-- Update Status Model Box -->
<div id="updateStatusModal" class="modal fade" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content bg-default">
<div class="modal-body">
<form class="form-horizontal" id="updateStatus">
#csrf
#method('PUT')
<div class="row">
<div class="col">
<div class="form-group text-center">
<h6 class="font-weight-bold">Stage 1</h6>
<label for="stage_1" class="switch">
<input type="checkbox" class="form-control" id="stage_1">
<div class="slider round"></div>
</label>
</div>
</div>
</div>
<div class="row">
<div class="col">
<div class="form-group">
<div class="col-md">
<label for="firstname">Coding</label>
<input type="text" class="form-control" id="first_name" value="" placeholder="Enter Completed Page Count">
</div>
</div>
</div>
</div>
</form>
</div>
<div class="modal-footer justify-content-between">
<button type="button" name="update_btn" id="update_btn" class="btn btn-outline-warning">Update</button>
</div>
</div>
</div>
</div>
jquery funtion:
// Edit action
$(document).on('click', '.updateStatus', function(){
$tr = $(this).closest('tr');
var data = $tr.clidren("td").map(function(){
return $(this).text();
}).get();
console.log(data);
$('#id').val(data[0]);
$('#job_id').val(data[2]);
$('#stage_1').val(data[3]);
$('#conversion').val(data[4]);
$('#updateStatusModal').modal('show');
});
I tried this method I found but this is not working. Can anyone provide me any pointers here?

I've just didn't seen your front scripts (also back-end codes), but instead I can share my implementation for that you need. It works perfectly like showed in this (screenshot).
Here I'll put front and back codes. There is functionality for editing existsing Datatable record, also record deletion.

I think this can help you and others to build wanted functionality. Here this could be also with more hint-comments, but as it not small, I can answer later via post comments.

i am building a Laravel ERP-like web application and am implementing a CRUD function modal like you. I have made mine a server-side processing application with resource APIs in Laravel. Well, please be reminded that i have cut the #extends(layout.app) & #section('stylesheet') parts to go right into the answer. You should extend them in your own application to make everything work.

I have not included any protection in it like gate, auth or so. But basically this is the skeleton of doing CRUD with dataTable in Laravel framework with both JS, Ajax, Jquery, PHP all in one. Kindly be reminded that the queries for such CRUD actions are directly linked to the Database server. If you want to show data processed by the DataTable, use your own jquery function to fetch and show them on the modal. My answer is not the best but i hope it helps you >:)

Laravel upload image through modal not working

Im making an inventory system in laravel and I want to upload an image every products that I have. My problem is I cant upload an image. I tried my old code in uploading photo and it is not working in my current project. The upload code you see in the controller is in a laravel collective form. But now, I am using a modal and an ajax request to save the inputs into the database. Can someone know what should I do about this? Btw, my modal doesnt have a form tag because I thought forms will not work in modals. Thanks in advance!

I Can’t add a comment, that is dumb ...
Your also going to likely need to encode the image data in the json.
See How do you put an image file in a json object?
(Fixed wording)

Why can't the edit-modal fetch the data(of the selected row) from my database?

So this is my brand.php file
And it portrays the edit part of the brand
so in this part we can probably see how the thing will look like
<!-- edit brand -->
<div class="modal fade" id="editBrandModel" tabindex="-1" role="dialog">

> --this one is the end part
And this is the fetching part, wherein once you click the button from the row(example row 1), a modal(Edit Modal will likely appear), but the thing is, once the modal appear, the data that is supposed to be fetched from the row is not on that modal ;-;
<?php
require_once '../../includes/connection.php';
$brandId = $_POST['brandId'];
$sql = "SELECT brand_id, brand_name, brand_active, brand_status FROM brands WHERE brand_id = $brandId";
$result = $connect->query($sql);
if($result->num_rows > 0) {
$row = $result->fetch_array();
} // if num_rows
$connect->close();
echo json_encode($row);
?>
Now the JScript part
This part is the filler part(like getting the data and now portraying the data and filling the input boxes etc..)
function editBrands(brandId = null) {
if(brandId) {
// remove hidden brand id text
$('#brandId').remove();
// remove the error
$('.text-danger').remove();
// remove the form-error

$('.form-group').removeClass('has-error').removeClass('has-success');
$('#edit-brand-messages').html('<div class="alert alert-success">'+
'<button type="button" class="close" data-dismiss="alert">×</button>'+
'<strong><i class="glyphicon glyphicon-ok-sign"></i></strong> '+ response.messages +
'</div>');
$(".alert-success").delay(500).show(10, function() {
$(this).delay(3000).hide(10, function() {
$(this).remove();
});
}); // /.alert
} // /if
}// /success
}); // /ajax
} // /if
return false;
}); // /update brand form
} // /success
}); // ajax function
} else {
alert('error!! Refresh the page again');
}
} // /edit brands function

Can you check the Network tab to see the result from server? You can debug your app by seeing that result.
By the way, there're two things that you may need to edit:
1/ If brandId is interger, you need to get it from $_GET by intval($_POST['brandId']) to prevent SQL Injection.
2/
if($result->num_rows > 0) {
$row = $result->fetch_array();
}
else {
$row = array();
}
your code need to return empty array if sql result is empty to avoid Undefined variable error.

How do I detect the id of a currently displayed element using Javascript?

I am basically using Gmail API to create send and reply to functionalities for myself. The problem is in the reply section. I am using jQuery to dynamically create divs for every message that appears in my inbox (max-count:10) and a separate set of divs (any single one to appear on clicking a mail link) wherein for each div, I am having the modal-header div for the subject, reply and close buttons whereas a modal-body div with an iframe for displaying the content.
var message1;
function appendMessageRow(message) {
$('.table-inbox tbody').append(
'<tr>\
<td>' + getHeader(message.payload.headers, 'From') + '</td>\
<td>\
<a href="#message-modal-' + message.id +
'" data-toggle="modal" id="message-link-' + message.id + '">' +
getHeader(message.payload.headers, 'Subject') +
'</a>\
</td>\
<td>' + getHeader(message.payload.headers, 'Date') + '</td>\
</tr>'
);
$('body').append(
'<div class="modal fade" id="message-modal-' + message.id +
'" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">\
<div class="modal-dialog modal-lg">\
<div class="modal-content">\
<div class="modal-header">\
<h4 class="modal-title" id="myModalLabel">' +
getHeader(message.payload.headers, 'Subject') +
'</h4>\
<button type="button"\
class="close"\
data-dismiss="modal"\
aria-label="Close" style="float:right;">\
<span aria-hidden="true">×</span></button>\
<span></span>\
<a data-toggle="modal" href="#reply-modal" id="reply-button" class="btn btn-primary">Reply</a>\
</div>\
<div class="modal-body">\
<iframe id="message-iframe-' + message.id + '" srcdoc="<p>Loading...</p>">\
</iframe>\
</div>\
</div>\
</div>\
</div>'
);
$('#message-link-' + message.id).on('click', function() {
var ifrm = $('#message-iframe-' + message.id)[0].contentWindow.document;
$('body', ifrm).html(getBody(message.payload));
message1 = message;
});
$('#reply-button).on('
click ',function(){
$("#reply-to").val(getHeader(message1.payload.headers, 'From')); $("#reply-subject").val('RE: ' + getHeader(message1.payload.headers, 'Subject')); $("#message-modal-" + message1.id).fadeOut(); $('div.modal-backdrop.fade.in').fadeOut();
});
}
I intend to use the Reply button to call a function which will fill the 'To' and 'Subject' field in the reply-modal(Reply button is an a tag with href=#reply-modal) that'd be visible after the message-modal-message.iddiv fades out. The problem is I am unable to get the id of this div which I need to fade out (along with that greyish background).
Also if you can see I need the whole message object and just not the message.id of the clicked message link so that I can transfer 'To' and 'Subject' to the newly appeared reply-modal div. But it just doesn't get the message.id of the clicked-on message but the last one in the list of mails displayed on the inbox page and so the #message-modal-message.id does not fade out as the message.id is not correct. Similarly, the 'To' and 'From' fields in the reply-modaldiv also contain information of the last mail in the list - doesn't matter which mail you've opened. Also as the message-modal-message.id div does not disappear, the reply-modal div appears behind it and I have to close the it div to see the reply-modal div.
I even tried having a JS function on the outside instead of the jQuery selector method $('#reply-modal').on('click',.. but couldn't do it.
Basically,
How do I get the message object after a message has been opened to view?

This is what exactly I was talking about. Sorry I couldn't paste the whole code in the questions too if that created some sort of confusion while trying to understand the question.
'Reply' button needs to be there for every message we add as divs to the display page, which also uses the two critical variables reply-to and reply-subject to pass the required data to the new reply form that opens up.
The closing of the 'Show message' div which was not possible earlier, was also linked to the message-id, which now becomes accessible.
Everything else is pretty neat; the functions required to send the reply are the same as sending a new email and are present at the very end of the code.
What I was unable to do was capture the message id of the currently displayed message on the click of "Reply" button. This is a "better" solution than a workaround, but man would it be shorter if I could have done what I'd have had wanted!

Modal displays strangely with bootstrap framework

On a web page who have many tab, i have a input box who do a search via a ajax call.
If there is no result, i would like to display a modal dialog box.
<div role="tabpanel">
<div class="row">
<div class="span12">
<nav role="navigation" class="navbar navbar-default navbar-right">
<form class="navbar-form" role="search">
<div class="checkbox">
<label>
<input type="checkbox" id="inactiveLodger"> Locataire inactif
</label>
</div>
<div class="input-group">
<input type="text" class="form-control" placeholder="Rechercher" name="srch-term" id="srch-term">
<div class="input-group-btn">
<button id="lodgerSearch" type="button" class="btn btn-default"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</nav>
<div class="modal fade" id="modalEmptyResult">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Résultat de recherche</h3>
</div>
<div class="modal-body">
<p>Aucun résultat ne correspondant à votre requête</p>
</div>
<div class="modal-footer">
Fermer
</div>
</div>
</div>
</div>
...
$('#lodgerSearch').on('click', function (e) {
var inactiveLodger = $('#inactiveLodger').is(':checked');
debugger;
var searchParam = $('#srch-term').val();
var url = "http://localhost:8080/lodgers/search";
if (searchParam != "") {
url = url + "?searchTerm=" + searchParam;
}
if (inactiveLodger == true) {
url = url + "?inactiveLodger=true";
}
jQuery.ajax({
type: "GET",
url: url,
success: function (data, status, jqXHR) {
debugger;
if (data.length == 0) {
$("#lodgerSearchResult").empty();
$('#modalEmptyResult').modal('show');
} else {
$("#lodgerSearchResult").empty().append(template(data));
}
},
error: function (jqXHR, status) {
// error handler
alert("error " + jqXHR + " - " + status);
}
});
// e.preventDefault();
});
Like we can see on the picture, we can see the dialog box, but it's seem transparent.
I created a basic example with similar problem.
