What you need to do is incorporate a login. This'll then pick up the $logged[username] and only let you post as that. Also flatfile ain't exactly secure =/

[Invent]

Add the following code near something like this:

if ($_GET['do] == "post") { << Im guessing its like that im not sure (im not gd at php)

--

Then add:

$user = $_POST[form_name_of_the_username_form];
$user = strtolower($user);

if($_POST[$user] == "colin") {
die(SOZ! ya cnt use dis pas lOLOl!)
}

Then have a clone of this file without the above stuff for you to post using.

NOTE: This is the most LAZY way to do it, you can do it much better but I just cba doing that now x)

[Colin-Roberts]

i would do it minimans way but it be a pain ill look into mysql..$user = $_POST[form_name_of_the_username_form];
$user = strtolower($user);

if($_POST[$user] == "colin") {
echo(Please enter your pass form here then it checks form against a text file to see if correct pass and if is continues)
}

Right. Ive tried to expand on my code, but as I said I dont really know PHP so I bet it wont work.

Anyway, here we go:

$user = $_POST[form_name_of_the_username_form];
$user = strtolower($user);

if($_POST[$user] == "colin") {
echo("<form method="POST" action="?do=login">user:<input type="text" name="user"><br>pass:<input type="password" name="pass"><br><br><input type="submit" value="Login"></form>");
die();
}

if($_GET['do'] == "login") {

$user = $_POST[user];
$pass = $_POST[pass];
$usermain = "put user here";
$passmain = "put pass here";

if($user == $usermain) && if($pass == $passmain) {
// continue with script
}
else {
die(LoL!&#172; did ya rly think ya cud gess teh l33tage pas!?);
}

// continue with script

Probs needs altering, etc

ill check it out miniman thanx
and can anyone fix the errors in minimans script
or would i put it in the file that has the form.
Edit were in this would i put it:

<?php

$name = $_POST['name'];
$website = $_POST['website'];
$message = $_POST['message'];

if(empty($name) OR empty($message))
{
echo "

<script language='javascript'>

alert('You need to fill out both of the form fields...');

</script>
";

}
else
{

echo "
";
$name = htmlspecialchars($name);
$message = htmlspecialchars($message);
$tag = ("<font size=\"1\" face=\"Verdana\">
<b>$name</b>: $message </font><br><br>");
function filter($tag)
{
$bad_words = explode(',', "tomato,lettuce,carrot,potato,broccoli,cucumber,pea" );
foreach ($bad_words as $naughty)
{
$tag = eregi_replace($naughty, "****", $tag);
}
return $tag;
}
function filter2($contents)
{
$bad_words = explode(',', "tomato,lettuce,carrot,potato,broccoli,cucumber,pea" );
foreach ($bad_words as $naughty)
{
$contents = eregi_replace($naughty, "****", $contents);
}
return $contents;
}

$read = fopen("content.txt", "r");
$contents = fread($read, filesize('content.txt'));
fclose($read);

$write = fopen("content.txt", "w");
fwrite($write, "$tag $contents");
fclose($write);
}
$input = $contents;
$output = filter($input);
echo $output;
$input = $tag;
$output = filter($input);
echo $output;
