I'm very new to PHP and I've cobbled this together from some other answers on here. Can anyone show me how to get the $errMsg to display? At present, a blank or incorrect name leads to a blank page. Is this because the form isn't being displayed again? If so, how should I go about 'reloading' the form with the error message?
<?php
$name = "Fred";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (!empty($_POST["name"])) {
if ($_POST["name"] == $name) {
include("welcomeFred.php");
}
else {
$errMsg = "Incorrect name";
}
}
else {
$errMsg = "Name required";
}
}
else { ?>
<html>
...
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<input type="text" name="name" required>
<span><?php echo $errMsg;?></span>
<input type="submit" value="Submit">
</form>
...
</html>
<?php } ?>
