Hi,
Simply put in the values in the form again.
A simple way to convey the idea:
From receiving PHP-script:
$url="http://www.example.com/myForm.php";
// do formchecking here
if ((isset($_POST["title"])) && (strlen($_POST["title"]) < 10)){
// title too short!
$url .= "?oldtitle=".urlencode($_POST["title"]);
header("Location: $url");
exit;
}
Then from the form-page:
<form action=".." Method="POST">
Title:
<input type="text" name="title" value="<?php echo
((isset($_GET["title"]))? $_GET["title"]: ""); ?>">
</form>
Simple example to show the idea.
If you want to send back multiple formelement, just add them together
with & (&).
