I'm working on a help ticket project and I have a good portion of it already working except this one aspect. I would like to display all ticket information (from a XML file) to the screen but then be able to append the comments with new comments to the ticket. I print all the ticket information without a problem it's appending it that is the problem. One, because my $_GET array is gone after submit I lose the ticket information, two I can't figure out how to just add new comments to the comments section for the particular ticket in my XML. Below is the code.
<!DOCTYPE html>
<html lang="en">
<head>
<title>
Kapsiak's Ticket Closer
</title>
<meta charset="utf-8">
<link rel="stylesheet" href="site.css">

<body>
<?php include 'header.php'; ?>
<?php include 'nav.php'; ?>

<div class="row">
<div class="sidel">

<main>
<div class="row">
<div class="sidel">
</div>
<div class="main">
<?php
// read all the ticket information to screen
$xml=simplexml_load_file("tickets.xml") or die ("Error: Cannot Display Tickets");
foreach($xml->children() as $ticket) {
if ($ticket['id'] == $_GET['id']) {
echo "<div class='helpLeft'>";
echo "<h3>Requester</h3>";
echo "<p>First Name: " . $ticket->fname . "</p>";
echo "<p>Last Name: " . $ticket->lname . "</p>";
echo "<p>Phone: " . $ticket->phone . "</p>";
echo "<p>School: " . $ticket->loc . "</p>";
echo "<p>Room: " . $ticket->room . "</p>";
echo "</div>";
echo "<div class='helpLeft'>";
echo "<h3>Device Information</h3>";
echo "<p>Device Type: " . $ticket->device . "</p>";
echo "<p>Manufacturer: " . $ticket->manu . "</p>";
echo "<p>Model: " . $ticket->model . "</p>";
echo "<p>Serial: " . $ticket->serial . "</p>";
echo "<p>Status: " . $ticket->status . "</p>";
echo "</div>";
echo "<div class='comments'>";
echo "<h3>Comments</h3>";
// check for new comments
if (!empty($_POST)){
$ticket->appendChild('comments', $_POST(comments));
}
echo "<p>" . $ticket->comments . "</p>";
echo "</div>";
}
}
echo "<br>";
?>
<div class="comments">
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<textarea name="comments" id="comments" cols="60" rows="10" required> </textarea><br>
<select size="1" name="status" id="status" required>
<option value="open">Select New Status </option>
<option value="In Progess">In Progress </option>

With the help of Blauharley I was able to figure out the rest of this issue. appendchild() and addchild() are not needed for SimpleXML. I had to just write the new variable to the XML using
$ticket->comments = $oldCom . " " . $_POST['comments'];
I then just had to save the XML using
file_put_contents("tickets.xml", $xml->asXML());
