Below is code I've created (Well, I borrowed the skeleton from someone else and added more functionality)

 

At one point, all of the options listed were working, but when I tried to integrate them all into one file, I have issues.

 

The only functional button, once a file is "loaded" into the editor, is the "Close File" button.  All the other buttons are essentially functioning as a close button.

 

Once I can get my buttons functional again, I plan to clean it up a bit, so fear not.  Anyway, please take a look and let me know what stupid mistake I made this time...

 

<?php 
function select_file() {
    //Establish which is the current directory (Just the current folder) and set to $value
    $dir = explode("\\",getcwd());
    $value = array_pop($dir);

    //Create a drop-down list with all of the files in the current directory (housing edit.php)
    echo "<form method=post><select name=\"file\" size=1>";
    $dir2 = scandir("..\\$value");
    foreach ($dir2 as $value2) {
        if (is_file($value2)) {
            echo "<option>$value2</option>";
        }
    }
    echo "</select><input type=\"submit\" name=\"open\" value=\"Open\"></form>";
    die;
}
if (!$_SESSION) {
    session_start();
}
echo "<html><head></head><body>";
$file = $_POST[file];
$_SESSION[file] = $file;

$loadcontent = $file; 
// Make sure a valid filename was given
if (strlen($loadcontent)>4) {
    // If save button was pressed
    if($_POST[save_file]) {
        $savecontent = stripslashes($_POST['savecontent']); 
        $fp = @fopen($loadcontent, "w"); 
        if ($fp) { 
            // Write contents of new file to $file
            fwrite($fp, $savecontent); 
            fclose($fp);
            // Refresh the page (loads the new file information)
            print "<html><head><META http-equiv=\"refresh\" content=\"0;URL=$_SERVER[php_SELF]\"></head><body>"; 
        }
