Submitted comment edit in textarea then save - php

Question

SO, I am working on a short script that takes a user's "bug report" and saves it. Showing the comment at the bottom of the page with an Edit button for editing. I want for that button to take the user to another page with a textarea, their comment would be editable here and a Save button to save their report. I am not sure how to link to the exact comment the user would upload.
Like this:
This is what I have so far:
Bug Reports
<form method="POST" action="Bugs.php">
<p>Bug Name <input type="text" name="name" /><br />
Hardware Type <input type="text" name="hw" /><br />
OS <input type="text" name="os" /> <br />
Frequency of Occurence <input type="text" name="freq" /></p>
<p>Proposed Solutions<br />
<textarea name="sol" rows="6" cols="100"></textarea>
<input type="submit" name="submit" value="Create New Bug Report" /></p>
</form>
<?php
$Dir = "comments";
if (is_dir($Dir)) {
if (isset($_POST['submit'])) {
if (empty($_POST['name'])) {
$String = "Unknown Visitor";
}
else
$String = stripslashes($_POST['name']) . "|";
$String .= stripslashes($_POST['hw']) . "|";
$String .= stripslashes($_POST['os']) . "|";
$String .= stripslashes($_POST['freq']) . "|";
$String .= stripslashes($_POST['sol']);
$CurrentTime = microtime();
$TimeArray = explode(" ", $CurrentTime);
$TimeStamp = (float)$TimeArray[1] + (float)$TimeArray[0];
/* File name is " Comment.seconds.microseconds.txt" */
$SaveFileName = "$Dir/Comment.$TimeStamp.txt";
if (file_put_contents($SaveFileName, $String)>0)
echo "File \"" . htmlentities($SaveFileName) . "\" successfully saved.<br />\n";
else
echo "There was an error writing \"" . htmlentities($SaveFileName) . "\".<br />\n";
}
}
if (is_dir($Dir)) { //show submitted reports on page
$CommentFiles = scandir($Dir);
foreach ($CommentFiles as $FileName) {
if (($FileName != ".") && ($FileName != "..")) {
echo "From <strong>$FileName</strong><br />";
echo "<pre>\n";
$Comment = file_get_contents($Dir . "/" . $FileName);
echo $Comment . "<a href=edit.php>Edit</a>";
echo "</pre>";
echo "<hr />";
}
}
}
?>

You really need to put all this into a database it would be much easier.
However.. when you foreach all the comments in the folder add a $_GET variable with the file name like this:
echo $Comment . "Edit";
Then with edit section you can call urldecode($_GET['com_id']) to access the file name and edit the comment.
