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 } ?>
You shouldn't put the rendering of the form in the else of your if structure. This is the reason your form isn't loaded when you submit the form.
Remove the else { ?> and <?php } ?> at the end of your file and it should work fine.
