After the click does not appear in bold

I created an internal email system within the project. When I receive a new message the column with the subject name in my table is bolded to inform that the message has not yet been read.
code:
<?php
while($row = mysqli_fetch_array($result))
{
?>
<section id="s1">
<div class="div1" id="minhaDiv" style="float: left;">
<table class="table table-bordered">
<tr>
<th width="20%">De</th>
<th width="60%">Assunto</th>
<th width="10%">Prioridade</th>
<th width="10%">Recebido</th>
</tr>
<tr>
<th width="10%" colspan=4>Recebido: <?php echo $row["Data"]; ?></th>
</tr>
<tr>
<td><?php echo $row["De"]; ?></td>
<td class="td-info view_data" id="<?php echo $row["Id"]; ?>" data-toggle="modal" href="#dataModal" width="20%" style="font-weight:bold" onclick="this.style['font-weight'] ='normal'"><?php echo $row["Assunto"]; ?></td>
<td><?php echo $row["Prioridade"]; ?></td>
<td><?php echo $row["Hora"]; ?></td>
</tr>
<tr>
<?php
}
?>
</table>
</div>
</section>
In the image, which is surrounded by green already clicked to read, the red has not yet vliquei to read, so it is bold:
I use this code to put bold inside the td:
width="20%" style="font-weight:bold" onclick="this.style['font-weight'] ='normal'"
The problem is that if you refresh the page, even after reading the messages, they come back in bold and should not. After clicking once, they can not be left in bold

Solution to achieve the condition.
I created a Status field in the database table, where 1 is unread message and 0 message is read, now is to create the condition in td with if. In the javascript with which I open the modal I made the following change:
$('.td-info').click(function(){
var item_id = $(this).attr("id");
var status = $(this).attr("Status");
$.ajax({
url:"./fetchRAD",
method: "POST",
data:{item_id:item_id, status:status},
success:function(data){
}
});
});
In td I indicated the id of the record in the id of td:
id="<?php echo $row["Id"]; ?>"
file with php:
if(isset($_POST["item_id"]))
{
$query = "Update centrodb.Alertas SET Status = '0' WHERE Id = '".$_POST["item_id"]."'";
$result = mysqli_query($conn, $query);
}
Pata check in the td we put like this:
width="20%" <?php echo $row["Status"] == '1'?' style="font-weight:bold" ':' style="font-weight:normal" '?>
td complete:
<td class="td-info view_data" id="<?php echo $row["Id"]; ?>" data-toggle="modal" href="#dataModal" width="20%" <?php echo $row["Status"] == '1'?' style="font-weight:bold" ':' style="font-weight:normal" '?>><?php echo $row["Assunto"]; ?></td>

Changing value in html table dynamically

I have an html table where i retrieve data from a database using PHP. The table is quite simple, i have three fields: Name, Quantity and Price. At the end of the table i have an additional field, Subtot, that shows the final cost (SumOfAllItems(Quantity*Price)).
I need to be able to change the "Quantity" value in each row and the "Subtot" should update accordingly. I also need to be able to set min/max value the user can use to update the cell.
I was thinking to add something like a button or any kind of list/input by the "Quantity" value in each row.
I think i need to use javascript but i am not sure, any suggestion is welcome.
Following my code.
Thanks
<table>
<tbody>
<tr>
<th>Name</th>
<th>Quantity</th>
<th>Price<th>
</tr>
<?php
while($row2 = $result->fetch_assoc())
{?>
<tr>
<td><?php echo $row2["Name"] ?></td>
<td><?php echo $row2["Quantity"] ?></td>
<td><?php echo $row2["Price"]?></td>
</tr>
<?php
$subtot = $subtot + ($row2["Price"] * $row2["Quantity"])
} ?>
<td></td>
<td><b>Subtot.</b></td>
<td><b><?php echo $subtot2 ." Euro"; $tot = $subtot1 + $subtot2;?> </b></td>
</tbody>
</table>

The following should work, however i do not recommend this method (any method btw) without any validation on server side.
You need this on top of your php file:
<?php
$total = 0;
Then your table like:
<table>
<thead>
<tr>
<th>Name</th>
<th>Quantity</th>
<th>Price<th>
</tr>
</thead>
<tbody>
<?php while($row2 = $result->fetch_assoc()) { ?>
<tr>
<td><?php echo $row2['name'] ?></td>
<td><input class="row" min="0" onchange="myFunction()" data-price="<?php echo $row2['price'] ?>" type="number" value="<?php echo $row2['quantity'] ?>"/></td>
<td><?php echo $row2['price'] ?></td>
</tr>
<?php
$total += $row2['price'] * $row2['quantity'];
}
?>
<td></td>
<td>
<b>Subtot.</b>
</td>
<td>
<b id="total"><?php echo $total; ?></b>
</td>
</tbody>
</table>
And you need the following script tag:
<script>
function myFunction(){
var total = 0;
var elements = document.getElementsByClassName("row");
for(var i = 0; i < elements.length; i++) {
total += elements[i].value * elements[i].dataset.price;
}
var totalEl = document.getElementById("total");
totalEl.innerHTML = total;
}
</script>
Again.. this is a very simple solution, but it should work.

how to update accept/reject of table of db in PHP

i created an appointments table where user1 would add appointments and user2 would accept/reject the appointment. now my problem is when the accept and reject are clicked it is displayed in the table but it is not updated in the db I've did a lot of research over this but hit a road block after road block, so I really hope your help in this, many thanks!
Here is an image of my appointments table:
Here is my code:
<table cellpadding="0" cellspacing="0" border="0" class="table table-condensed" id="example">
<thead>
<tr>
<th>appoinment ID</th>
<th>Date</th>
<th>time</th>
<th>teacher</th>
<th>parent</th>
<th> accept/reject </th>
<th>state</th>
</tr>
</thead>
<tbody>
<?php
$query=mysqli_query($conn, "select * from `app` left join `par` on par.par_id=app.par_id
left join `tea` on tea.tea_id=app.tea_id
ORDER BY app_id DESC");
if($query === false)
{
throw new Exception(mysqli_error($conn));
}
while($row=mysqli_fetch_array($query))
{
$ann_id=$row['app_id'];
$date=$row['date'];
$msg=$row['time'];
$username = $row['username'];
$username = $row['p_username'];
?>
<tr>
<td><?php echo $row['app_id'] ?></td>
<td> <?php echo date('j/m/y',strtotime($row['date'])); ?></td>
<td><?php echo $row['time'] ?></td>
<td><?php echo $row['p_username'] ?></td>
<td><?php echo $row['username'] ?></td>
<td>
reject
accept
</td>
<td>
<div class="chgtext">PENDING</div>
</td>
</tr>
<?php
if (isset($_GET['state'], $_GET['app_id'])) {
$stmt = mysqli_prepare($conn, "UPDATE app SET state = ? WHERE app_id = ?");
mysqli_stmt_bind_param($stmt, "sd", $_GET['state'], $_GET['s.app_id']);
$stmt->execute();
$stmt->close();
}
}
?>
</tbody>
</table>
</div>
</form>

You have an error there. You are using $_GET request with setting it in url. Change your html tag like below
reject
accept <!-- I assumed that column names in database were app_id and state
And in php code
if (isset($_GET['state'], $_GET['app_id'])) {
$stmt = mysqli_prepare($conn, "UPDATE app SET state = ? WHERE app_id = ?");
mysqli_stmt_bind_param($stmt, "sd", $_GET['state'], $_GET['app_id']);
$stmt->execute();
$stmt->close();
}
}
I hope it will help you. If there is any problem then kindly tell me

Edit source data of HTML table

I wrote this part of code:
<table class="table table-hover">
<thead>
<tr>
<th>Status</th>
<th>MPK</th>
<th>Full Name</th>
<th>Phone Number</th>
<th>Project Start Date</th>
<th>Project End Sales Date</th>
<th>Project Installation Date</th>
<th>Project End Date</th>
<th>General Manager</th>
<th>IT Project Manager</th>
<th>Notes</th>
</tr>
</thead>
<?php
$file = '/var/lib/jenkins/workspace/Update_JSON/terminarz.json';
$fp_terminarz = fopen($file, 'r');
$toecho = fread($fp_terminarz, filesize($file));
$data = json_decode($toecho, true);
fclose($fp_terminarz);
foreach($data as $key=>$value){ ?>
<tbody>
<tr>
<td>Opening process</td>
<td><?php echo $value["MPK"]; ?></td>
<td><?php echo $value["Restaurant Name"]; ?></td>
<td><?php echo $value["Phone Number"]; ?></td>
<td><?php echo $value["Project Start Date"]; ?></td>
<td><?php echo $value["Project End Sales Date"]; ?></td>
<td><?php echo $value["Project Installation Date"]; ?></td>
<td><?php echo $value["Project End Date"]; ?></td>
<td><?php echo $value["Restaurant Manager"]; ?></td>
<td><?php echo $value["IT Project Manager"]; ?></td>
<td><?php echo $value["Notes"]; ?></td>
</tr>
<?php } ?>
</tbody>
</table>
I show JSON content in HTML table using PHP script.
My problem is - I want to have possibility to edit any row (one at a time) and after saving changes update file terminarz.json.
What is the best way to do this? I was thinking about js scripts, which would change css style of row and show Edit button near row (after pointing it with mouse cursor).
Is this good approach to this task? Or how should I do this? I would appreciate any advice.

For the UI/UX part:
Why not have an edit icon in the last column of table with a column heading Edit.
Have hidden input fields with proper names and value pre-filled.
On click of the edit icon, simply hide the data and show the input fields, so the user can edit the data. Also, switch the edit icon to save and also give an option to cancel out.
Something like this: http://nathancahill.github.io/table-edits/
For updating the data:
$jsonString = file_get_contents('terminarz.json');
$data = json_decode($jsonString, true);
foreach ($data as $key => $entry) {
if ($entry['id'] == $updated_row_id) {
$data[$key]['name'] = "value";
}
}
And then save it back using:
$newJsonString = json_encode($data);
file_put_contents('terminarz.json', $newJsonString);

Its a good approach just do one more thing wrap table in form and make input hidden element for each field when you edit a single row then update that hidden element with new entry and at last submit the form which contain all the entries and on server side catch that data and convert into json and save it

Click function showing div elements when not clicked out

I have an admin panel that I am creating. I have a left panel section and then the right side which shows the div when the panel button is clicked. I created a fiddle to show what it looks like and to help me explain this...
https://jsfiddle.net/jq8c51c9/
In the Fiddle it works just like it should, but I took out all of my php. The problem is around the Announcements div, it shows the div for the League Dues under it. Also once you click on announcements and then click on another panel button, if I click on Announcements again the only thing that will show up is this..
Announcements Current Announcements
League Dues
Again this is NOT doing this in the Fiddle.
Here is the full code for the area that the issue resides in. I have been stuck on this forever and cannot figure out why I am having difficulties with only these two divs.
Does anyone see what it is that I am doing wrong?
Announcements
try {
//Prepare
$con = mysqli_connect("localhost", "", "", "");
if ($user_stmt = $con->prepare("SELECT `id` FROM users")) {
$user_stmt->execute();
$user_stmt->bind_result($user_id);
if (!$user_stmt) {
throw new Exception($con->error);
}
$user_stmt->store_result();
$user_result = array();
//while ($user_row = $user_stmt->fetch()) {
?>
<div class="announcement_success"></div>
<p>Add New Announcement</p>
<form action="" method="POST" id="insert_announcements">
<input type="hidden" value="<?php echo $userid; ?>" id="approved_id" name="user_id" />
<textarea rows="4" cols="50" id="announcement_message" name="message" class="inputbarmessage" placeholder="Message" required></textarea>
<label for="contactButton">
<button type="button" class="contactButton" id="submit_announcement">Add Announcement</button>
</label>
</form>
<?php
if ($announcements_stmt = $con->prepare("SELECT * FROM announcements")) {
$announcements_stmt->execute();
$announcements_stmt->bind_result($announcements_id, $announcements_user_id, $announcements_messages, $announcements_date);
if (!$announcements_stmt) {
throw new Exception($con->error);
}
$announcements_stmt->store_result();
$announcements_result = array();
?>
Current Announcements
<table>
<tr>
<th>ID</th>
<th>Username</th>
<th>Message</th>
<th>Date</th>
</tr>
<?php
while ($row = $stmt->fetch()) {
?>
<tr>
<td><?php echo $announcements_id; ?></td>
<td><?php echo $announcements_username; ?></td>
<td><?php echo $announcements_messages; ?></td>
<td><?php echo $announcements_date; ?></td>
</tr>
</table>
<?php
}
}
}
}
catch (Exception $e)
{
echo "Error: " . $e->getMessage();
}
?>
</div>
<div id='dues'>League Dues</div>
</div>

You have an error when building the announcement-table.
The closing </table> tag is inside the while loop, so the html will be screwed up, making everything after the closed table disappear.
So change the while loop to:
....
<?php
while ($row = $stmt->fetch()) {
?>
<tr>
<td><?php echo $announcements_id; ?></td>
<td><?php echo $announcements_username; ?></td>
<td><?php echo $announcements_messages; ?></td>
<td><?php echo $announcements_date; ?></td>
</tr>
<?php
}
?>
</table>
<?php
....
Anyway, I recommend to build your html first in a variable and echo it out later alltogether. That makes cleaner code and reduces risk of inconsitency of html tags. When using with HEREDOC you even don't have to bother about quotes.
In your case that could for example look like that:
<?php
$table_head = <<<EOT
<tr>
<th>ID</th>
<th>Username</th>
<th>Message</th>
<th>Date</th>
</tr>
EOT;
$table_content = "";
while ($row = $stmt->fetch()) {
$table_content.= <<<EOT
<tr>
<td>$announcements_id</td>
<td>$announcements_username</td>
<td>$announcements_messages</td>
<td>$announcements_date</td>
</tr>
EOT;
}
$announcement_table = "<table>".$table_head.$table_content."</table>";
echo $announcement_table;
