Closed 2 years ago.
i am trying to display and update read/unread messages. I have a column in database msg_read, that is by default has a value of 0. 0 means read, and 1 means unread. Need guidance to update the status when the message is read. With the guidance of Mr. Andre, the unread messages are showing Bold now, but when read, messages become normal (not bold).

I found some errors in your code and some structural failures.
if you are working with PHP in a HTML page, use alternative syntax
see:
https://www.php.net/manual/en/control-structures.alternative-syntax.php
you don't need to rewrite the complete row again for the read message, only put a condicional on the style attribute.
you was calling read_msg instead of $read_msg
new code:
<div class="tab-pane userprof-tab" id="tab-10">
<div class="table-responsive border-top">
<table class="table table-bordered table-hover mb-0 text-nowrap">
<thead>
<tr>
<th>Name</th>
<th>Jetski</th>
<th>Sender Email</th>
<th>Phone</th>
<th>Post Code</th>
<th>Message Date</th>
<th>Message</th>
</tr>
</thead>
<tbody>
<?php while ($row = mysqli_fetch_assoc($SelectBoat)) : ?>
<?php
$full_name = $row['full_name'];
$boatname = $row['boatname'];
$sender_email = $row['sender_email'];
$phone = $row['phone'];
$post_code = $row['post_code'];
$message = $row['message'];
$msg_date = $row['msg_date'];
$seller_id = $row['seller_id'];
$msg_read = $row['msg_read'];
?>
<tr <?= ($msg_read == "0") ? 'style="font-weight:900"' : '' ?>>
<td><?php echo $row['full_name']; ?></td>
<td><?php echo $row['boat_name']; ?></td>
<td><?php echo $row['sender_email']; ?></td>
<td><?php echo $row['phone']; ?></td>
<td><?php echo $row['post_code']; ?></td>
<td><?php echo $row['msg_date']; ?></td>
<td>
<!-- View Message -->
<i class="fa fa-eye"></i>
<!-- View Message -->
<!--****** View Message Modal ******-->
<div class="modal fade" id="view<?php echo $row['id']; ?>" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-md" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title"><strong>From <?php echo $row['sender_email']; ?></strong> </h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p style="word-wrap: break-word; white-space: initial;"><?php echo $row['message']; ?></p>
</div>
</div>
</div>
</div>
<!--****** End View Message Modal ******-->
</td>
</tr>
<?php endwhile; ?>
</tbody>
</table>
</div>
</div>
UPDATE:
to update the status of the message just like i told you in the commnent. add this to your code:
add this sttribute to your view button:
onclick="readMSG(this, '<?php echo $row['id']; ?>')"
add this script and modify to work in your case:
<script>
function readMSG(attribute, id) {
$(attribute).parent().parent().css('font-weight', 'normal')
$.ajax({
type: "GET",
url: "readmsg.php",
data: {
id: id
},
success: function (){
$(attribute).parent().parent().css('font-weight', 'normal')
}
});
}
</script>
the php controller file readmsg.php:
$update = mysqli_query($con, "UPDATE `seller_contact` SET `read_msg`=1 WHERE `id` =" . $_GET['id']);
if ($update) {
return ['success' => 'success'];
} else {
return ['error' => 'error'];
}
try to understand the code and adapt to work in your case. if work, don't forgot to accept the answer ;)
