Problem

[xwin]

Posted this awhile back, hasen't been fixed, but I tried and tried my best, no luck, so now, I cleaned it down to just the bare bones to make debugging easier, and need your help.

<?php
if ($userid <> "NULL") 
{ 
if(isset($_POST["newtopic"])) 
{ 
$f = $_POST["fid"]; 
$post = $_POST["reply"]; 
$topicname = $_POST["tname"]; 
$description = $_POST["tdesc"]; 
$replyFile = fopen ("../data/forum{$f}.txt", "r"); 
foreach($replyFile as $reply) { 
$replyparts = explode ("|", $reply); 
$tid = trim($replyparts[0]); 
$tid = $tid + 1;
fclose($replyFile); 
$postFile = fopen ("../data/forum".$f.".txt", "r+"); 
fwrite($postFile, "\n$tid|$topicname|$description|$post|$id|0|0|-"); 
fclose($postFile); 
header("Location: ".$HTTP_SERVER_VARS['HTTP_HOST']."/forums/index.php?act=rtopic&f={$f}&id={$tid}"); 
}
}
} 
else
{ 
echo "<div align='center'>"; 
echo "<table border='1' cellspacing='0' width='158' height='36'>"; 
echo " <tr>"; 
echo " <td width='158' height='36'><p align='center'>Error: Not logged in!</td>"; 
echo " </tr>"; 
echo "</table>"; 
echo "</div>"; 
echo "</font>";
}
?>

Here's the error: Warning: Invalid argument supplied for foreach() in /home/virtual/site18/fst/var/www/html/forums/process/newtopic.php on line 11

I really need help on this. Thanks.

Perhaps you meant
$replyFile = file("../data/forum{$f}.txt");
?

Check out the difference:

http://www.php.net/file

Thanks so much!

Now it's just the problem that it overwrites the last entry.

But I -need- the file pointer to be at the top. Any way to do this?

If you want to add the line to the top of the text file, you'll need to read in the whole file, then write out the new line, then write out the whole rest of the file again.

Basically, with text files, you can either append stuff to the end, or rewrite the whole thing.
