How do I get an input form to reload itself

@Swashbuckler — quick diagnosis and practical fixes based on the replies from @pcschrottie, @GaryKing and @mcldev.

Dreamweaver’s Insert Record server behavior often writes a “success” redirect into the generated code (it may also add a hidden field with the URL). Search the generated files for the literal filename shown after submit (for example data.htm) or for Dreamweaver’s redirect variable (commonly MM_redirectTo). Edit that server behavior or remove/change the redirect so the form does not send users to the .htm file.

A more robust pattern is Post/Redirect/Get (PRG): process the POST, then redirect back to the form page so a fresh form appears and browser refresh won’t resubmit the data. Example:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // validate and insert into DB here

    header('Location: /path/to/form.php'); // redirect to fresh form
    exit;
}

To show a one-time success message after the redirect, use a session “flash”:

session_start();
$_SESSION['flash'] = 'Record saved.';
header('Location: /path/to/form.php');
exit;

Then on the form page:

session_start();
if (!empty($_SESSION['flash'])) { echo $_SESSION['flash']; unset($_SESSION['flash']); }

Troubleshooting checklist: search all generated files for data.htm or MM_redirectTo; confirm the form’s action points to the correct PHP URL; make sure the form page is served via HTTP from a PHP-enabled server (not opened as a local .htm file); avoid any output (including BOM/whitespace) before calling header(); and guard redirects so they only run after a successful insert to prevent redirect loops.
