If userX try to add an address that is already in the file, it while generate an errormsg. And if userX try to remove an address that is not in the file, it while result in an errormsg.
Well, I thought that I had solved it... but it seems to me that the driectory that I have my file in is accessed (at least the directory seems to been "touched").
Wanna see the code? (some of the comments are in swedish)
Code:
if ($alltOK) {
$file = "./temp/test"; // Filen som innehåller adresser.
$lock = $file . ".lock"; // Låsfilen som ev. låser upp användadet av "Filen".
$temp = $file . ".temp"; // Tempfilen som använd vid
$mailAdmin = "list-admin@skaraborg.nsf.scout.se";
$mailExtra = "From: list-admin@skaraborg.nsf.scout.se";
if (!file_exists($lock)) {
// SKAPA LÅSFILEN
if (!copy($file,$lock)) die ("Ett internt fel har uppstått! Försök igen senare."); // Skapa låsfilen.
$notInFile = true;
// KONTROLLERA FILINNEHÅLL
$content = @file($file) or die ("Kunde inte öppna en för detta nödvändig fil...");
foreach ($content as $line_num => $line) {
if (preg_match("/\^$email$/i", $line)) {
$notInFile = false;
}
}
// LÄGG TILL I FILEN!
if ($action=="subcribe") {
if ($notInFile) {
$fh = fopen($file, "a");
flock($fh, 2);
fwrite($fh, "$email\n");
flock($fh, 3);
fclose($fh);
// SKAPA MAIL TILL ADMIN
$mailSubject = "$name har lagts till i e-postlistan";
$mailMsg = "$name från $group har med e-postadressen \"$email\" lagts till i e-postlistan.";
// SKICKA MAIL TILL ADMIN
mail($mailAdmin, $mailSubject, $mailMsg, $mailExtra);
// SKAPA MAIL TILL USER
$mailSubject = "Bekräftelse: Du har lagts till i vår e-postlista";

lol... Glad to hear you kept working on it and didn't just sit around waiting for someone to give you an answer. But, as you see, there is no need to use a temp file... What you do is up to you...
