Why is HTML in php function not visible in view source - php

Question

function that runs when i want to edit a client status.
// deletes (sets inactive) client
function setClientStatus($client) {
if ($_GET['action'] == "setinactive") {
//database functions
$sql = 'UPDATE clients SET active="0" WHERE id="'. $client .'"';
$result = query($sql);
confirmQuery($result);
//set message to user to display
$_SESSION['error'] = false;
$msgs[] = "Client was set to inactive and removed from the list!";
$_SESSION['userMsg'] = $msgs;
}
if ($_GET['action'] == "setactive") {
//database functions
$sql = 'UPDATE clients SET active="1" WHERE id="'. $client .'"';
$result = query($sql);
confirmQuery($result);
//set message to user to display
$_SESSION['error'] = false;
$msgs[] = "Client was successfully restored!";
$_SESSION['userMsg'] = $msgs;
}
//display clients page with changes made
redirect('?page=clients');
}
function that displays the message.
//function that shows message and styles accordingly
function message($msgs) {
if(!empty($msgs)) {
foreach ($_SESSION['userMsg'] as $msg) {
if ($_SESSION['error'] == false) {
echo '<div class="noError">'.$msg.'</div>';
} else {
echo '<div class="error">'.$msg.'</div>';
}
}
}
unset($_SESSION['userMsg']);
unset($_SESSION['error']);
echo "hello";
}
here is where i call it in my page....
div class="pageContainer">
<?php
//display messages
message($_SESSION['userMsg']);
?>
</div>
Now when everything is run and i select to edit and client status (or add client, edit client as they all have the same message section, just with different message) i can see the message displayed on the screen. i have a javascript script that will hid the message after 5 seconds, but it doesn't hide. after viewing the page source i notice that the section of code is not visible. again, i can see it clearly see the message that is suppose to be there "Client was set to inactive and removed from the list!" (or whatever message is set to display) but it is NOT show in the view source html.
pic of page loaded with message
here is the view source.....
<div class="pageContainer">
<div>
** updated **
this small example script renders the html, but my above script doesn't...
function setError() {
$error[] = "Password field is to short";
$_SESSION['userMsg'] = $error;
//return $_SESSION['msg'];
}
function message($errors){
if(!empty($errors)) {
foreach ($_SESSION['userMsg'] as $error) {
echo $error.'<br>';
}
}
unset($_SESSION['userMsg']);
}

If I get you right, you want to display $msgs, so why you iterate $_SESSION['userMsg'] ?
Probably the $_SESSION['userMsg'] is null or empty. If you want to display the $msgs just iterate it. And later add to session if really needed. In you code, you always unset the $_SESSION['userMsg'] in the end of function, probably it is always null then. I didn't see the $_SESSION['userMsg'] needed here :
//function that shows message and styles accordingly
function message($msgs) {
if(!empty($msgs)) {
foreach ($msgs as $msg) {
if ($_SESSION['error'] == false) {
echo '<div class="noError">'.$msg.'</div>';
} else {
echo '<div class="error">'.$msg.'</div>';
}
}
}
unset($_SESSION['error']);
echo "hello";
}

After reading your comments, this is related to javascript problem. You should add the id in <div> in order for it's works.
if ($_SESSION['error'] == false) {
echo '<div id="noError" class="noError">'.$msg.'</div>';
} else {
echo '<div id="error" class="error">'.$msg.'</div>';
}
