Her er en jeg lavede for lang tid siden:
Kan nok laves anderledes! :O)
<?php
session_start();
$message = "Feltet er ikke udfyldt!";
function tjekform($var) {
global $message;
if(isset($_SESSION[$var])) {
if($_SESSION[$var] == $message) {
echo" * <font color=\"red\" size=-1\">". $_SESSION[$var] ."</font>";
}else{
echo" value=\"". $_SESSION[$var] ."\"";
}
unset($_SESSION[$var]);
}
}
if(isset($_POST["formsubmit"])) {
$_SESSION["fejlnr"] = 0;
$_SESSION["antal"] = 0;
foreach($_POST as $key=>$value) {
$_SESSION["fejlnr"]++;
if(trim($value) == "") {
$_SESSION["antal"]++;
$_SESSION[$key. $_SESSION["fejlnr"]] = $message;
}else{
$_SESSION[$key] = $value;
}
}
header("Location:". $_SERVER["PHP_SELF"] ."");
exit;
}
?>
<html>
<head>
<title>Tjek formfelter</title>
</head>
<body>
<center>
<?php
if(isset($_SESSION["antal"]) && $_SESSION["antal"] != 0) {
echo"<b>Du mangler at udfylde ". $_SESSION["antal"] ." felter!</b><p>";
unset($_SESSION["antal"]);
}
?>
<form method="post" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
<input type="hidden" name="formsubmit" value="true">
