Hi,

Plain html pages are not refered to as programs, just html files.
Unless the Javascript in them is worth calling a program. ;-)

What you need is something like this:
<?php
// just an example, we expect a formelement named firstname
// If not set, redirect to error.html
if (!isset($_POST["firstname"])){
// refuse
header("Locatio n: http://www.example.com/error.html");
exit;
}

// do your normal processing here.

?>

Re: return to html

Erwin,

Thanks for the post. Maybe you could help me with this code. The code is
not transfering to variables to the search.php program.

<html>
<head>
<title>testin g downloaded query form</title>
</head>
<body>

<h2>Search</h2>

<form name="search" method="post" action="search. php">
Seach for: <input type="text" name="find" /in
<Select NAME="field">
<Option VALUE="fname">F irst Name</option>
<Option VALUE="lname">L ast Name</option>
<Option VALUE="info">Pr ofile</option>
</Select>
<input type="hidden" name="searching " value="yes" />
<input type="submit" name="search" value="Search" />
</form>

</body>
</html>

none of the variable are set in search.php

How are you accesing the variables there?

Stop here.

I think you are relying on old (bad) PHP examples that use register_global s.
$searching is empty in your example.

Use: $_POST["searching"] instead.
That contains the the value of the formelement named "searching" .
(They are case sensitive.)

But users aren't to be trusted to know that a back button exists :P

Re: return to html

My mistake. The copied program was severly lacking. Have made all
patches. Search program had no POST statements amoung other things.

Thanks to all
