Display alert based on value and session - php

Question

What I am trying to accomplish is if the user verified column is 0 it will echo out the message below if the users verified column is 1 it wont show the message.
so I have it working but if they close it I don't want it to show again for that session.
$db = dbconnect();
$stmt = $db->prepare("SELECT * FROM users WHERE ID = ?");
$stmt->bind_param('s', $_SESSION['ID']);
$stmt->execute();
$result = $stmt->get_result();
while ($row = mysqli_fetch_assoc($result)) {
$id = $row['ID'];
$verified = $row['Verified'];
if ($verified == 0) {
echo '
<div class="alert alert-warning alert-dismissible fade show" role="alert">
Your account has not been verified.
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>';
return true;
} else {
return false;
}
}

You should set a session variable to show the alert based off of the value retrieved from the database, like so :
PHP
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if (isset($_POST['verifymsg']) {
$_SESSION['VerifyMessage'] = false;
}
}
$db = dbconnect();
$stmt = $db->prepare("SELECT * FROM users WHERE ID = ?");
$stmt->bind_param('s', $_SESSION['ID']);
$stmt->execute();
$result = $stmt->get_result();
while ($row = mysqli_fetch_assoc($result)) {
$id = $row['ID'];
if (!isset($_SESSION['VerifyMessage']) {
$_SESSION['VerifyMessage'] = ($row['Verified'] == 0) ? true : false;
}
if ($_SESSION['VerifyMessage']) {
echo '
<form method="POST" action="yourscript.php">
<input type="hidden" name="verifymsg" />
<div class="alert alert-warning alert-dismissible fade show" role="alert">
Your account has not been verified.
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
</form>';
return true;
} else {
return false;
}
}
Here, I used a ternary operation to set a session variable called 'VerifyMessage' if it isn't already set. I also added a <form> and hidden input with the name verifymsg to the html.
When this script sees verifymsg as a post variable, it will set the session variable to false. This can work anyway you want, for example with ajax, but it shows a concept.
