Updating parts of a .php page

Is it possible to update a page and proceeding the next function, similar to refreshing it?
I have a page that when Save button is pressed, it will submit the data into earnings_amendment_account_add.php, and the page will be refreshed.
Now, what I'm trying to achieve through AJAX is for the data to be submitted, and then display Success Notification and refresh the dataTable upon pressing Save in my modal.
Example, this part of the page <?php include 'includes/notif-info-display.php'; ?> will trigger this upon submitting a page.
This Screenshot only displays after I submit the form and the page was refreshed.
<section class="content">
<div id = "content">
<?php include 'panels/accounting_panel.php'; ?>
<?php include 'includes/notif-info-display.php'; ?>
</div>
Now, I did some modifications to avoid refreshing the page. It will send the data to the database, but I cant' find a way for the dataTable to be refreshed, and for <?php include 'includes/notif-info-display.php'; ?> to be reloaded and display if it is Success or Fail, based on the triggers in my earnings_amendment_account_add.php.
$(document).ready(function () {
// Listen to click event on the submit button
$('#add').click(function (e) {
e.preventDefault();
// Add trigger based on button name, value
var add = $("#add").val();
var add_accountcode = $("#add_accountcode").val();
var accounttitle = $("#accounttitle").val();
var accounttype = $("#accounttype").val();
var postedby = $("#postedby").val();
var dateposted = $("#dateposted").val();
$.post("earnings_amendment_account_add.php",
{
// Add trigger based on button name, value
add: add,
add_accountcode: add_accountcode,
accounttitle: accounttitle,
accounttype: accounttype,
postedby: postedby,
dateposted: dateposted
}).complete(function() {
console.log("Success");
});
});
});
The trigger comes from earnings_amendment_account_add.php page
if(sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET))){
$_SESSION['success'] = 'Earnings Amendment Account Data added successfully';
}
else{
$_SESSION['error'] = $conn->echo .print_r(sqlsrv_errors(), true);
}
}
else{
$_SESSION['error'] = 'Fill up add form first';
}
?>
This is the includes/notif-info-display.php
<?php
if(isset($_SESSION['error'])){
echo "
<div class='alert alert-danger alert-dismissible'>
<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>
<h4><i class='icon fa fa-warning'></i> Error!</h4>
".$_SESSION['error']."
</div>
";
unset($_SESSION['error']);
}
if(isset($_SESSION['success'])){
echo "
<div class='alert alert-success alert-dismissible'>
<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>
<h4><i class='icon fa fa-check'></i> Success!</h4>
".$_SESSION['success']."
</div>
";
unset($_SESSION['success']);
}
?>
This happens after I click this the #addnew modal's submit.
<form autocomplete='off' class="form-horizontal" method="POST" action="earnings_amendment_account_add.php">
FORMS HERE ---
<div class="modal-footer">
<button type="button" class="btn btn-default btn-flat pull-left" data-dismiss="modal"><i class="fa fa-close"></i> Close</button>
<!-- Add Button ID, Change Type to button, add name, add value -->
<button type="button" class="btn btn-primary btn-flat" name="add" value="add" id="add"><i class="fa fa-save"></i> Save</button>
</form>
</div>
</div>
Everything works perfectly fine, the data is added, my only problem is that I can't seem to find a way for <?php include 'includes/notif-info-display.php'; ?> to be reloaded again and display the Success Notification upon pressing save.
This is my modal.
Is there a way for this to happen? <?php include 'includes/notif-info-display.php'; ?> will be reloaded and display if the Data Submitted was a success, or a failure, and at the same time, refresh the dataTable and show the latest data there?

use echo "<meta http-equiv='refresh' content='0'>";
after your if(isset($_SESSION['success'])){for the reload.
Also set $activateSuccess = true; here.
Then echo your message with
if($activateSuccess == true) {
echo "
<div class='alert alert-success alert-dismissible'>
<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>
<h4><i class='icon fa fa-check'></i> Success!</h4></div>";
}
return;

You must handle this issue on your jquery code.In php code handling the ajax request you must send back the success data as JSON. Then in your ajax request complete section, handle this data, create a table row to add to your Datatable and pop a success notification.
Php does not update partially. this is a matter of client, php runs in server.

Bootstrap Model Window Not Showing by Calling Through JQuery

What I am trying to do is that pop up a bootstrap js model by using jquery call that is
$("#id").modal("show")
but it's not working in any case, there are several cases mentioned in this link but none is working in my case.
also I have gone through the following links
bootstrap model is not working
Bootstrap modal window not showing
calling to bootstrap model for a link
Bootstrap modal - popup window not showing
https://getbootstrap.com/docs/4.0/components/modal/
but I am not able to get any help, I can trigger the model by having an extra button and calling click() function of button by jquery, this works fine but not modal case.
My Modal code is here
<div class="modal fade" id="addLocationTagModel" tabindex="-1" role="dialog" aria-labelledby="myModalLabelLocation">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" id="idButtonCloseLocation" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabelLocation">Enter Location</h4>
</div>
<div class="modal-body">
<div class="row">
<div class="col-lg-9 col-md-9 col-sm-12 col-xs-12">
<div class="form-group">
<?php
$preferredLocation = "";
if (strtolower(getUserPreferredLocation($row_user, $conn)) !== "no") {
$preferredLocation = getUserPreferredLocation($row_user, $conn);
}
?>
<input type="text" class="form-control" value="<?php echo $preferredLocation; ?>" placeholder="Location" id ="locationSuggested" name="locationSuggested" />
<span>
<span id="suggesstionBoxLocation" ></span>
</span>
</div>
</div>
<div class="col-lg-3 col-md-3 col-sm-12 col-xs-12">
<div class="pLace-order">
<button type="button" name="buttonLocation" onclick="getTagSelected();" class="btn btn-success" value="submit">Submit</button>
</div>
</div>
</div>
</div>
</div>
</div>
Jquery call is here
<script>
function detachStore(url){
//alert(url);
//document.getElementById("buttonDeleteStore").click(); // Click on the checkbox
// For Testing Purpose to set the data-target
jQuery.noConflict();
$(document).ready(function () {
$("#addLocationTagModel").modal("toggle");
alert("Hello");
//$("#buttonDeleteStore").click();
// $('#addLocationTagModel').appendTo("body").modal('show');
});
}
And HTML and mixed PHP code is here below, I have onclick function on the element call that is working perfectly.
<td>
<?php
$i = 1;
foreach (unserialize($row['store_id']) as $store_id) {
$stores = $conn->query("select * from tb_stores where ID = " . $store_id);
while ($stores_row = $stores->fetch_assoc()) {
$store_price = $conn->query("select * from tb_add_price_of_products where product_id=" . $row["ID"] . " and store_id=" . $stores_row["ID"]);
$store_price_row = $store_price->fetch_assoc();
//echo $store_price_row["price"];
if ($i == 1) {
echo "<a href='#' data-toggle='modal' title='$"
. $store_price_row["price"] . "-" . $stores_row["location"] . "'"
. " onclick=\"detachStore('" . $url . "product-registry?action=delete-store&product_id=". $row["ID"] . "&store_id=" . $stores_row["ID"] . "');\" >"
. $stores_row['name'] . "</a>";
} else {
echo ", <a href='#' data-toggle='modal' title='$"
. $store_price_row["price"] . "-" . $stores_row["location"] . "'"
. " onclick=\"detachStore('" . $url . "product-registry?action=delete-store&product_id=". $row["ID"] . "&store_id=" . $stores_row["ID"] . "');\" >"
. $stores_row['name'] . "</a>";
}
$i++;
}
}
?>
<button type="button" id="buttonDeleteStore" data-toggle="modal" data-target="#add_price_modal">Button</button>
</td>
I have spent hours on it, even no JavaScript error, May be I am doing something wrong at some place, if anybody can pull it out that would be appreciated.

I was going through some other post
TypeError: $(...).modal is not a function with bootstrap Modal
and I replaced
$("#id").modal("show")
with
jQuery("#id").modal("show")
and this trick worked here and it started working. Still I don't know the reason like why it wasn't working with $.
One more thing, we need to include the jQuery.noConflict(); above then the statement to avoid repetitions.

Using AJAX to update a dynamic webpage

I made a webpage that consists of projects, where each project consists of a list of files. All of this information is acquired from a MySQL database. I've implemented a feature that allows users to comment on each file and reply to each other's comments. I have a php function called "place comments" which recursively places comments for each file shown below.
This is executed for every file and every file is displaced similarly using a while loop and some statements that echo html code.
However, the issue I'm having is using AJAX to post comments without the page refreshing. Since each file id is different, I would have to update every selector with a particular file id and run placeComments again for every file.
However I'm not sure how to accomplish this. I'm able to update my database through AJAX everytime I submit a comment.
I know you can do something like the following and it will update any selector with the id "id":
$(document).ready(function() {
$.get('comments.php', function (data) {
$('#id').html(data);
});
});
But I'm not sure how I can do this iteratively for every file id where each file id is a php variable?
Is there a way I can communicate with JS through PHP so it updates comments
for all file ids? If so, how?
I realized that this is a terrible design, but I'd like to do this without starting my project from scratch.
Place comments function:
function placeComments($mysqli, $parentId, $fileId) {
$sql = "SELECT * FROM Comments WHERE parent = $parentId AND file = $fileId ORDER BY UNIX_TIMESTAMP(date) ASC";
$comments = $mysqli->query($sql);
while($comment = $comments->fetch_assoc())
{
echo '
<ul class="comments">
<li class="clearfix">
<div class="post-comments">
<p class="meta"> '. $comment['date'] .' '. $comment['username'] .' says : <i class="pull-right">
<p>'
.
$comment['content']
.
'</i></p><br><br>';
echo '<div class = "col-sm-12 reply panel-group">';
echo '<div class="panel panel-default">';
echo '<p><a data-toggle="collapse" href="#'. $comment[
'file'] . '-' . $comment['id'] . '"> Reply </a></p>';
echo '<div id="'. $comment['file'] . '-' . $comment['id'] .'" class="panel-collapse collapse">';
echo '<div class="panel-body">';
if(isset($_POST['submitComment-' . $comment['file'] . '-' . $comment['id']]))
{
$user = $_POST['username'];
$content = $_POST['content'];
$fileId = $_POST['id'];
$parent = $_POST['parent'];
$date = date('Y-m-d H:i:s', time());
filterComment($mysqli, $fileId, $user, $parent, $content, $date);
}
echo '<form method="post" class="form-horizontal" id="commentForm" role="form">
<div class="form-group">
<div class="col-sm-10 form">
<h5><b> Name: <b></h5>
</div>
<div class="col-sm-10 form">
<textarea class="form-control" name="username" id="username" rows="1"></textarea>
</div>
<div class="col-sm-10 form">
<h5><b> Reply: <b></h5>
</div>
<div class="col-sm-10 form">

</div>
<div>
<input class = "form-control" type = "hidden" value = '. $comment['file'] . ' name = "id" id = "id" />
</div>
<div>
<input class = "form-control" type = "hidden" value = '. $comment['id'] . ' name = "parent" id = "parent" />

</div>
<div class="form-group">

echo '</div>';

How to send href value in tablesorter to dialog modal?

Problem
I have problem in sending/passing href value in tablesorter to my dialog modal.
It's become complicated when the target location is the dialog modal.
Example (table.php)
This is a partial of my code since above it is a PDO PHP query to get my data from database. Important point is at the href code inside foreach
if($stmt->rowCount() > 0){
$r=$stmt->fetchAll();
echo "<table class='tablesorter-dropbox' id='myTable' style='width:97%; table-border: 1'>";
echo "<thead>";
echo "<tr style='text-align: center;'>";
echo "<th style='text-align: center;'>No.</th>";
echo "<th style='text-align: center;'>Conference Name</th>";
echo "<th style='text-align: center;'>Conference Sponsor</th>";
echo "<th style='text-align: center;'>Date (Start)</th>";
echo "<th style='text-align: center;'>Date (End)</th>";
echo "<th style='text-align: center;'>Budget</th>";
echo "<th style='text-align: center;'>Status</th>";
echo "<th style='text-align: center;'>Approve</th>";
echo "<th style='text-align: center;'>Reject</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
//echo "<td><a href='reject.php?idstudent=".$row['matricno']."&idbook=".$row['serialno']."'><img src='pic/remove-icon-png-15.png' width=15px></a></td>";
foreach ($r as $row){
echo "<tr align='center'><td>".$row['id']."</td><td>". $row['conf_name'] ."</td><td>". $row['conf_sponsor'] ."</td><td>". $row['conf_fDate'] ."</td><td>". $row['conf_lDate'] ."</td><td>RM ". $row['conf_budget'] ."</td><td>". $row['conf_status'] ."</td><td><a href='#' onclick='this.href='indexSuperUser.php?idconf=".$row['id']."' role='button' data-toggle='modal' data-target='#login-modal3?idconf=".$row['id']."'><img src='images/good.png' width=15px></a></td><td><a href='#?idconf=".$row['id']."' role='button' data-toggle='modal' data-target='#login-modal4'><img src='pic/remove-icon-png-15.png' width=15px></a></td></tr>";
//$startrow++;
}
echo "</tbody>";
echo "</table>";
}
else{
echo "<p align='center'>Nothing to show you :( I am really sorry for this T_T </p>";
}
Example #2 (dialogmodal.php)
Now here is where i want to display the variable from the table. Just for testing purpose i am trying to display the idconf to see if the id displayed successfully.
<!-- BEGIN # MODAL LOGIN -->
<div class="modal fade" id="login-modal3" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="display: none;">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header" align="center">
<img style="position:relative; LEFT:20px; WIDTH:100px; HEIGHT:100px" id="img_logo" src="images/logofpeNEW2.png">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
</button>
</div>
<!-- Begin # DIV Form -->
<div id="div-forms">
<!-- Begin # Register Super User Form -->
<form id="approved-form">
<div class="modal-body">
<div id="div-register-msg">
<div id="icon-register-msg" class="glyphicon glyphicon-chevron-right"></div>
<span id="text-register-msg">Approve this event?.</span>
</div>
<input type="text" id="idconf" class="form-control" value="<?php echo $_GET['idconf']; ?>">
</div>
<div class="modal-footer">
<div>
<button type="submit" class="btn btn-primary btn-lg btn-block" style="background-color: green">Approve</button>
</div>
</div>
</form>
<!-- End # Register Super User Form -->
</div>
<!-- End # DIV Form -->
</div>
</div>
</div>
<!-- END # MODAL LOGIN -->
<!--END LOGIN AREAD--------------------------------->
Result
The result? Its either undefined index: idconf or nothing. Means that im trying to send variable like this #?idconf=".$row['id']."....... since if i put like this dialogmodal.php?idconf=".$row['id'].".. my dialog ends up opening another dialog that is weird to say.
Flow
The flow is simple. Start from the table.php where it will grab the data from my database and display using tablesorter plugins. Then it will open at the dialog modal. Right side of the table have approved and rejected. So this two things comes from the href itself. Just like on the picture.
Duplicated?
Maybe yes. but its a little bit different. I give here two link almost the same problem as me:
Dynamically load information to Twitter Bootstrap modal
Send parameter to Bootstrap modal window?
However. My problem a bit slightly difficult i think. Mine is not about show the data when button clicked. But instead, i need to click the button to open the modal dialog first then clicked href button to open each row with unique id.
my stackoverflow account could be blocked at any time since i got many downvoted question. I dont know what happen to people nowadays. So i try to do proper and detailed here. If still downvoted, it will be my last here.. :)

Oh never mind. I got it work out by using from someone. I can't remember the link but credit to him for mentioning about using "data-your variable" and call it using jquery and send it back to the modal dialog id. Like this
<a id='approved' href='#' role='button' data-toggle='modal' data-target='#login-modal3' data-id='".$row['idconf']."' data-confname='".$row['conf_name']."' data-confsponsor='".$row['conf_sponsor']."' data-conffdate='".$row['conf_fDate']."' data-confldate='".$row['conf_lDate']."' data-confbudget='".$row['conf_budget']."' data-confstatus='".$row['conf_status']."' data-useremail='".$row['email']."' data-username='".$row['name']."' data-balanceuser='".$row['balance']."' data-m='".$row['matricNo_fk']."'><img src='images/good.png' width=15px></a>
See how many data i send? Then call it using jquery like this..
$(document).on("click", "#approved", function () {
var idconf = $(this).data('id');
var confname = $(this).data('confname');
var confsponsor = $(this).data('confsponsor');
var conffdate = $(this).data('conffdate');
var confldate = $(this).data('confldate');
var confbudget = $(this).data('confbudget');
var confstatus = $(this).data('confstatus');
var useremail = $(this).data('useremail');
var username = $(this).data('username');
var balanceuser = $(this).data('balanceuser');
var m = $(this).data('m');
After declare this variable, then on the next line of this code, send it to the modal dialog id such as this.
$(".modal-body #idconf").val( idconf );
$(".modal-body #nameconf").val( confname );
$(".modal-body #sponsorconf").val( confsponsor );
$(".modal-body #dateSconf").val( conffdate );
$(".modal-body #dateEconf").val( confldate );
$(".modal-body #budgetconf").val( confbudget );
$(".modal-body #statusconf").val( confstatus );
$(".modal-body #emailuser").val( useremail );
$(".modal-body #nameuser").val( username );
$(".modal-body #balanceuser").val( balanceuser );
$(".modal-body #m").val( m );
$('#addBookDialog').modal('show');
On the modal dialog, use the id mentioned.
<form id="approved-form">
<div class="modal-body">
<div id="div-register-msg">
<div id="icon-register-msg" class="glyphicon glyphicon-chevron-right"></div>
<span id="text-register-msg">Approve this event?.</span>
</div>
<input type="hidden" id="idconf" class="form-control" value="" disabled>
<input type="text" id="nameconf" class="form-control" value="" disabled>
<input type="text" id="sponsorconf" class="form-control" value="" disabled>
<input type="text" id="dateSconf" class="form-control" value="" disabled>
<input type="text" id="dateEconf" class="form-control" value="" disabled>
<input type="text" id="balanceuser" class="form-control" value="" disabled>
<input type="text" id="budgetconf" class="form-control" value="" disabled>
<input type="text" id="statusconf" class="form-control" value="" disabled>
<input type="text" id="emailuser" class="form-control" value="" disabled>
<input type="text" id="nameuser" class="form-control" value="" disabled>
<input type="hidden" id="m" class="form-control" value="" disabled>
</div>
I am not saying this is efficient in terms of speed or whatever. but it solved my problem and user problem. Case solved

using jquery in php post method

I am not very experienced in jquery and ajax but I need the following. After users have successfully logged in they can download pdf files from the page. The site has a collapse div from where they can choose which file to download. Everything is done in php and works ok. However, if the file is not found the collapse div is closed back. In other words the web page gets reloaded. So the user has to make a new selection newly which is inconvenient. So I would the following. If the file is not found then the div should stay collapsed and the previous value in the input field 's' on the form. I know this should be done via jquery or javascript. I have tried the following but it does not work.
//PHP
<?php
//if download is clicked
if (isset($_POST["download"])) {
$data = $_POST["s"];
//if file is found
if (fileexists($data){
// We'll be outputting a PDF
header('Content-type: application/pdf');
// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');
// The PDF source is in original.pdf
readfile($data);
}
//else the div should remain open
else{
echo "<script> if ($('#collapseOne').is(':hidden')) {
$('#collapseOne').show();
}</script>";
}
}
?>
<div id="collapseOne" class="panel-collapse collapse">
<div class="panel-body">
<form id='searchForm' method="post" action=''>
<p><label>Select Month</label></p>
<input id='s' name = 's' type='text' required><br><br>
<button type="submit" id='download' name='download' class='btn btn-default btn-lg'>
<span class='glyphicon glyphicon-download-alt'></span> Download
</button>
<br> <br>
<button id='download1' name = 'download1' class='btn btn-default btn-lg'>
<span class='glyphicon glyphicon-download-alt'></span> Download All
</button>
</form>
</div>
</div>

In short, you echo PHP into Javascript
<script>
$(document).ready(function(){
var hasDownload = "<?php echo $_POST['download']; ?>";
var oldInput = "<?php echo $_POST['s']; ?>";
if(hasDownload == false) {
$('#collapseOne').show();
$('input#s').val(oldInput);
}
})
</script>
When the server serves your file, those values will be present for your Javascript. Place you're jQuery at the bottom in another if statement & a doc ready block so that the dom is loaded first and echo your PHP variables into Javascript variables to perform your jQuery logic.
<?php
if (isset($_POST["download"]) && fileexists($_POST["s"]) {
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="downloaded.pdf"');
readfile($_POST["s"]);
}
?>
<div id="collapseOne" class="panel-collapse collapse">
<div class="panel-body">
<form id='searchForm' method="post" action=''>
<p><label>Select Month</label></p>
<input id='s' name = 's' type='text' required><br><br>
<button type="submit" id='download' name='download' class='btn btn-default btn-lg'>
<span class='glyphicon glyphicon-download-alt'></span> Download
</button>
<br> <br>
<button id='download1' name = 'download1' class='btn btn-default btn-lg'>
<span class='glyphicon glyphicon-download-alt'></span> Download All
</button>
</form>
</div>
</div>
<?php if(isset($_POST["download"]) == false && fileexists($_POST["s"] == false) : ?>
<script>
$(document).ready(function(){
var hasDownload = "<?php echo $_POST['download']; ?>";
var oldInput = "<?php echo $_POST['s']; ?>";
if(hasDownload == false) {
$('#collapseOne').show();
$('input#s').val(oldInput);
}
})
</script>
<?php endif; ?>

Try using this!
$.ajax({
url:"/path/to/your/script/",
type: "post",
data: //fetch the data which you want to pass
}).done(function(status){
//status is the data returned from the script called
});
