Well, basically djr33 and I made up this code for saving/restoring fields using images.
Just two issues that we need to fix (and need help):
- When you put a line break into a textarea, and restore it, it won't use line breaks
- When you save the new data, it doesn't overwrite it, it shoves it aside (Try it)
index.php

session_start();
include("settings.inc.php");
$user.=".txt";
$loc = $folderloc."/".$user;
/*
Delete file contents
*/
if (isset($_GET['cmd']) && $_GET['cmd'] == "delete") {
$fp = fopen($user,"w");
fwrite($fp,"");
fclose($fp);
//header("location:index.php");
echo "File Contents Deleted";
}
if (isset($_GET['cmd']) && $_GET['cmd'] == "content") {
echo "<strong>File Contents</strong><br>";
echo nl2br(file_get_contents($loc));
}
/*

*/
$parts = file($loc);
foreach ($parts as $part) {
$part = explode('=',$part);
$fields[$part[0]] = htmlentities(stripslashes($part[1]));
}
