updating sql with php - php

Question

I need to be able to update my sql table from open to close task.
I already wrote code for this but it is not working properly. On the modal it shows 2 'continue' buttons and right now the task table contains two tasks. Can somebody help me?
This is what the modal looks like:
and this is my code:
<?php
if (isset($_POST["closetask"])) {
$close_task_id = mysqli_real_escape_string($con, $_POST["close_task_id"]);
$sql = "UPDATE task SET task_status='closed' WHERE id_task='$close_task_id'";
$result = mysqli_query($con, $sql);
if ($result) {
$_SESSION['success'] = "Task closed";
$_SESSION['text'] = "Task has been closed successfully";
$_SESSION['icon'] = "success";
} else {
$_SESSION['success'] = "Error";
$_SESSION['text'] = "Unkown error, please try again";
$_SESSION['icon'] = "error";
}
}
?>
<?php
$query = "SELECT * FROM task ORDER BY id_task DESC";
$result = mysqli_query($con, $query);
?>
<!-- reject button -->
<form action="task-view.php" method="post" enctype="multipart/form-data">
<div id="rejectModal" class="modal fade" role="dialog" >
<div class="modal-dialog modal-lg">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Close this task?</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<div class="d-flex align-items-center justify-content-center form-group" >
<p class="align-items-center text-center" for="company">This button means closing the task. Are you sure you want to continue?</p>
</div>
</div>
<div class="modal-footer">
<?php
while ($row = mysqli_fetch_array($result)) {
if ($row['task_status'] == 'open'){
$check_task = '
<input type="text" name="close_task_id" class="form-control" value="' . $row["id_task"] . '" hidden>
<button class="btn btn-success" type="submit" name="closetask" class="btn btn-success">Continue</button>
</button>
';
}
echo '
<br>
' . $check_task . '
';
}
?>
</div>
</div>
</div>
</div>
</div>
</form>
<!-- end of reject button-->
<?php
if (isset($_SESSION['success']) && $_SESSION['success'] != '') {
?>
<script>
swal({
title: "<?php echo $_SESSION['success']; ?>",
text: "<?php echo $_SESSION['text']; ?>",
icon: "<?php echo $_SESSION['icon']; ?>",
button: "OK",
});
</script>
<?php
unset($_SESSION['success']);
}
?>

Answer 1

Well, after going through your code snippet,
I could see this query
$query = "SELECT * FROM task ORDER BY id_task DESC";
$result = mysqli_query($con, $query);
meaning this fetches all records in the task table, the two continue buttons you see are coming from the while loop
while ($row = mysqli_fetch_array($result)) {
....
}
it logically implies you have two records or rows in your database task table and all the records where retrieved from the table.
