Trying to write html form program that calls php prog. If php prog has
problem with what was entered would like to return from php to html program.

Is this possible and if so, how?

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("Location: http://www.example.com/error.html");
exit;
}

// do your normal processing here.

?>

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>testing 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">First Name</option>
<Option VALUE="lname">Last Name</option>
<Option VALUE="info">Profile</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_globals.
$searching is empty in your example.

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

echo "<h2>Results</h2><p>";
}

//If they did not enter a search term we give them an error

The back button works.

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

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

Thanks to all
