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!
Modal Create.

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">
<div class="modal-dialog">
<div class="modal-content">
<form class="form-horizontal" id="editBrandForm" action="php_action/editBrand.php" method="POST">

> --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');
// modal loading
$('.modal-loading').removeClass('div-hide');
// modal result
$('.edit-brand-result').addClass('div-hide');
// modal footer
$('.editBrandFooter').addClass('div-hide');
$.ajax({
url: 'fetchSelectedBrand.php',
type: 'post',
data: {brandId : brandId},
dataType: 'json',
success:function(response) {
// modal loading
$('.modal-loading').addClass('div-hide');
// modal result
$('.edit-brand-result').removeClass('div-hide');
// modal footer
$('.editBrandFooter').removeClass('div-hide');
// setting the brand name value
$('#editBrandName').val(response.brand_name);

// brand id
$(".editBrandFooter").after('<input type="hidden" name="brandId" id="brandId" value="'+response.brand_id+'" />');
// update brand form
$('#editBrandForm').unbind('submit').bind('submit', function() {
// remove the error text
$(".text-danger").remove();
// remove the form error
$('.form-group').removeClass('has-error').removeClass('has-success');
var brandName = $('#editBrandName').val();
var brandStatus = $('#editBrandStatus').val();
if(brandName == "") {
$("#editBrandName").after('<p class="text-danger">Brand Name field is required</p>');
$('#editBrandName').closest('.form-group').addClass('has-error');
} else {

// success out for form

} else {

// success out for form
$("#editBrandStatus").closest('.form-group').addClass('has-success');
}
if(brandName && brandStatus) {
var form = $(this);
// submit btn
$('#editBrandBtn').button('loading');
$.ajax({
url: form.attr('action'),
type: form.attr('method'),
data: form.serialize(),

$('#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.

Modal pop up one time per user

In my website, I am using a simple modal popup with some input controls ( name, email, button).
The purpose of modal popup is:
After filling all mandatory fields, if user press "submit" button they will get one .pdf file.
I launch the modal upon onload.
Here, I am trying to do:
Open the modal popup only once for a user, or
Don't want to show the modal popup to users who previously filled out the form already
Here is the code of my modal popup:
<script type="text/javascript">
$(document).ready(function () {
$("#eBookModal").modal('show');
});
</script>
<div class="modal fade" id="eBookModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<div class="row">
<h4 class="modal-title text-center" style="color:#FFFFFF;">Download eBook</h4>
</div>
</div>
<div class="modal-body">
<form role="form" id="eBookform" class="contact-form"
action="file.pdf">
<div class="row">
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control form-text" name="FName" autocomplete="off" id="eBook_FName" placeholder="First Name" required>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control form-text" name="LName" autocomplete="off" id="eBook_LName" placeholder="Last Name" required>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<input type="email" class="form-control form-text" name="email" autocomplete="off" id="eBook_email" placeholder="E-mail" required>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12 text-center" id="eBook_download">
<button type="submit" class="btn main-btn" style="color:#fff !important;">Download Now</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>

You have to keep record of the modal displays. To store that info, you can either use a cookie or the localStorage. Based on the stored value, you can decide whether to show the modal or not.
The sample below uses the localStorage as an example:
$(document).ready(function () {
// Check if user saw the modal
var key = 'hadModal',
hadModal = localStorage.getItem(key);
// Show the modal only if new user
if (!hadModal) {
$('#eBookModal').modal('show');
}
// If modal is displayed, store that in localStorage
$('#eBookModal').on('shown.bs.modal', function () {
localStorage.setItem(key, true);
})
});
Available as a Codepen too.
If you would like to hide the modal just from those who already submitted the form, you should set the flag upon form submit, like so:
$('#eBookform').on('submit', function (event) {
// event.preventDefault();// depending on your use case
localStorage.setItem(key, true);
})
Note: to reset the stored value, just call localStorage.removeItem('hadModal').

If you just to show the modal one time for first time visit and previous code didn't work try this !
$(window).load(function(){
var Modal = document.getElementById('myModal');
var key = 'hadModal',
hadModal = localStorage.getItem(key);
if (!hadModal) {
Modal.style.display = "block";
localStorage.setItem(key, true);
}
});

if (document.cookie.indexOf("ModalShown=true")<0) {
jQuery(document).ready(function() {
setTimeout(function(){
$("#homepageModal").addClass("modal-show")
}, 1000);
});
var date = new Date(),
expires = 'expires=';
date.setDate(date.getDate() + 1);
expires += date.toGMTString();
document.cookie = 'ModalShown=true ;' + expires + '; path=/';
}

How do you get this script to work in Bootstrap 5 without using jQuery?
$(document).ready(function () {
// Check if user saw the modal
var key = 'hadModal',
hadModal = localStorage.getItem(key);
// Show the modal only if new user
if (!hadModal) {
$('#eBookModal').modal('show');
}
// If modal is displayed, store that in localStorage
$('#eBookModal').on('shown.bs.modal', function () {
localStorage.setItem(key, true);
})
});

Trying to prevent modal close on button click - javascript

I'm working on a small project in ASP.NET MVC, and in one part I need help of javascript.
Acctually there is modal with three inputs, old password, new and confirm new password,
and in case all fields are empty I need to prevent user from closing modal, I tried to solve it like this:
function comparePasswords(currentPassword) {
//Here I will loop throught all of my three inputs to check are they empty
var formInvalid = false;
$('#allInputs input').each(function () {
if ($(this).val() === '') {
formInvalid = true;
}
});
if (formInvalid) {
alert('One or more fields are empty.');
$('#ChangePassword').modal({
backdrop: 'static',
keyboard: false // I need to prevent user from clicking ESC or something
})
}
}
But I get following error (check the image):
EDIT:
FULL CODE:
<div class="form-group">
<label for="UserPassword">Pw:</label>
#Html.TextBoxFor(model => model.PasswordHash, new { #class = "form-control custom-input", data_toggle = "modal", data_target = "#ChangePassword", ariaDescribedby = "basic-addon1" })
</div>
#*Modal for ChangePassword which is opening when user clicks on control above ^*#
<div id="ChangePassword" class="modal fade" role="dialog">
<div class="modal-dialog modal-sm">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Updating password</h4>
</div>
<div class="modal-body" id="allInputs">
#*Modal Old Password*#
<div class="form-group">
<label for="UserPassword">Old password:</label>
<input type="password" class="form-control custom-input modal-trigger" value="Eldin123" name="oldPassword" id="OldPassword" data-toggle="modal">
</div>
#*Modal New Password*#
<div class="form-group">
<label for="UserPassword">New password:</label>
<input type="password" class="form-control custom-input modal-trigger" value="" name="newPassword" id="NewPassword" data-toggle="modal">
</div>
#*Modal Repeat New Password*#
<div class="form-group">
<label for="UserPassword">Confirm new password:</label>
<input type="password" class="form-control custom-input modal-trigger" value="" name="confirmPassword" id="ConfirmNewPassword" data-toggle="modal">
</div>
#*Modal - submit*#
<div class="confirm-login">
<button type="button" class="btn custom-btn-big" onclick="comparePasswords();">NEXT</button>
</div>
</div>
</div>
</div>
</div>#*end of Modal for ChangePassword*#
#*Confirm button*#
<div class="confirm-login">
<button class="btn custom-btn-big" data-target="#">SAVE ALL CHANGES</button>
</div>
</div>
</div>
</div> #*End of User / Administration*#
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
<script>
function fieldInvalid() {
var formInvalid = false;
$('#allInputs input').each(function () {
if ($(this).val() === '') {
formInvalid = true;
console.log(formInvalid);
}
});
}
function passwordsInvalid() {
var invalidPassword = true;
var oldPw = $("#OldPassword").val();
var newPw = $("#NewPassword").val();
var confirmNewPw = $("#ConfirmNewPassword").val();
if (oldPw != newPw) {
alert('Postojeći password nije ispravan.');
}
else if (oldPw != confirmNewPw) {
alert('Password koji ste unijeli se ne slaže.');
}
else {
invalidPassword = false;
}
return invalidPassword;
}
var comparePasswords = function () {
if (fieldInvalid()) {
alert('One or more fields is empty.');
}
else {
if (!passwordsInvalid()) {
$("#ChangePassword").modal('hide');
}
}
}
</script>
}
So when someone clicks on password input, modal will be opened, and from that modal after informations are there user should click on button "NEXT" and there is event onclick which is calling comparePasswords method.

You are missing bootstrap library file.
Order of the file should be
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
Same Problem (missing bootstrap.js) http://jsfiddle.net/1aeur58f/676/
Problem resolved (by adding bootstrap.js) http://jsfiddle.net/1aeur58f/677/
Hope this will help you.

get data From Bootstrap 3 modal form with jquery ajax

i wrote this to get form data and post it to a php page and do some proccess and get back a result to me,i start with getting post data from my bootstrap modal form and i found that the script can't take values from modal form,because the php part i can't upload it to fiddle or somewhere else.
i upload it on my server for rapid review
click on compose;
complete the fields
and when Send button clicked it expect to modal form sent some value to jquery ajax(on submit) but nothing sent from modal inputs to ajax and the whole $_POST array remain null,and whats going on?
hours and hours i searched for doc's and example's,but i couldn't found any answer,some examples works with bootstrap 2,and nothing for the bootstrap 3.
bootstrap 3.3.1,jquery 2.1.1
here is the modal code:
<div class="modal fade" id="largeModal" tabindex="-1" role="dialog" aria-labelledby="largeModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Compose</h4>
</div>
<div class="modal-body">
<form id="sendmail" data-async method="post" role="form" class="form-horizontal">
<div class="form-group">
<label class="col-sm-2" for="inputTo">To</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputTo" placeholder="comma separated list of recipients">
</div>
</div>
<div class="form-group">
<label class="col-sm-2" for="inputSubject">Subject</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="inputSubject" placeholder="subject">
</div>
</div>
<div class="form-group">
<label class="col-sm-12" for="inputBody">Message</label>
<div class="col-sm-12">
<textarea class="form-control" id="inputBody" rows="18"></textarea>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary" value="Submit">Send</button>
<div id='response'></div>
</div>
</form>
</div>
</div>
</div>
jQuery:
$(document).ready(function () {
$('#sendmail').submit(function () {
$('#response').html("<b>Loading response...</b>");
$.ajax({
type: 'POST',
url: 'proccess.php',
data: $(this).serialize()
})
.done(function (data) {
$('#response').html(data);
})
.fail(function () {
alert("Posting failed.");
});
return false;
});
});
Simple PHP Code:
print_r($_POST);

In your code, this which is provided inside the $.ajax method's object refers ajax object. And it seems that you need to refer to the form from which you have to get the data and serialise it and send it into AJAX request.
Try following code,
$(document).ready(function () {
$('#sendmail').submit(function () {
var that = this;
$('#response').html("<b>Loading response...</b>");
$.ajax({
type: 'POST',
url: 'proccess.php',
data: $(that).serialize()
})
.done(function (data) {
$('#response').html(data);
})
.fail(function () {
alert("Posting failed.");
});
return false;
});
});
here I have referred the form object this by assigning it to that
