Well, Here is the code of my new project .. Actually it''s just s scrap or it..
I have made 2 files.
the 1st file is test.php with of course creating a new file called testdb.txt.
And the file called admin.php
here is the code.
Code of test.php
[php]
<?php
$db = "testdb.txt";
$name= $_POST["name"];
$like = $_POST["like"];
$submit = $_POST["submit"];
$full_mess = "<br> MY name is $name.<br>I like to $like.";
$seprate = "<br>..............";
if($submit == submit)
{
$f_handle = fopen($db,''a'');
fwrite($f_handle,$full_mess.$seprate."\n");
fclose($f_handle);
"<i>Message sent...";
}
else
{
echo "Message Can''t be sent...";
}
?>
<form name="beta_testing" action="test.php" method="post">
<br>
Name ; <input name="name" type="text" size="18">
<br>
Like ; <input name="like" type="test" size="20">
<br>
<input name="submit" type="submit" value="submit">
</form>
<?php
@include($db);
?>
[/php]
and admin.php
[php]
<?php
$db = "testdb.txt";
$pass = $_POST["pass"];
$line_to_del = $_POST["line"];
$log_in_form = "<form name=\"moderation_login\" action=\"admin.php\" method=\"post\">
<br>

$lines_del_form = "<form name=\"moderation\" action=\"admin.php\" method=\"post\">
<br>
Line Number to delete.. Lines are counted from Down to up...<input name=\"line\" type=\"text\" size=\"15\">
<input name\"submit\" type=\"submit\" value=\"submit\">
</form>";
if($pass == 123)
{
@include($db);
$file = file_get_contents($dbname);
$array = explode("\n", $file);
array_diff(array($array), array($line_to_del));
echo $lines_del_form;
}else
{
echo "<b> Please insert correct value into pass field...";
echo $log_in_form;
}
?>
[/php]
