Sending formdata to PHP

Anon

How do I create a form where I can enter a URL and some more data that will be send to the following script. I also want to enter <start grab text> and <stop grab text> in the form.
The text that is finally created shouldn't be displayed, but saved to a file with a name that was also entered in the form. (A total of 4 form fields that are send to the script). Thanks for the help.

<?php

$fd= fread(fopen("http://URL.to/GRAB/", "r"), 100000);

if ($fd)
{
$start= strpos($fd, "<start grab text>");
$finish= strpos($fd, "<stop grab text>");
$length= $finish-$start;
$code=Substr($fd, $start, $length);
}

echo $code;

This should do the trick:

<head>
<title>Formulier</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<form name="form1" method="post" action="post.php">
<p> Website url:
<input type="text" name="website">
</p>
<p> Start text:
<input type="text" name="start">
</p>
<p> Stop text:
<input type="text" name="stop">
</p>
<p> Filename:
<input type="text" name="filename">
</p>
<p>
<input type="submit" name="Submit" value="Submit">
</p>
</form>
</body>

and post.php:

<?php

$fd= fread(fopen("$website", "r"), 100000);

if ($fd)
{
$start= strpos($fd, "$start");
$finish= strpos($fd, "$stop");
$length= $finish-$start;
$code=Substr($fd, $start, $length);
}

$data = $filename;
$file = fopen($data, "a+");
fputs($file, "$code");
fclose($file);

echo "Here's your file <META HTTP-EQUIV=\"REFRESH\" CONTENT=\"1; URL=$filename\">";
?>
