I have form in my site example.com/pp.php and that form´s action is pp.php because that script is not some external file, but inside of that page. The problem is I need to put header("Location: http://example.com/pp.php#contactForm"); because after pressing Send button I want to reload page on exact position which is /pp.php#contactForm. But header Location is not working.
<form action="pp.php" method="post">
<label>Name:</label>
<input type="text" name="name" value="<?php if($_POST['name']) {
echo $_POST['name']; } ?>" />
<label>Email:</label>
<input type="text" name="email" value="<?php if($_POST['email'])
{ echo $_POST['email']; } ?>" />
<label>Message:</label><br />
<textarea name="message" rows="20" cols="20"><?php
if($_POST['message']) { echo $_POST['message']; } ?></textarea>
<label><img src="captcha.php"></label>
<input type="text" name="code"> <br />
<input type="submit" class="submit" name="submit" value="Send
message" />
</form>
This is php
<?php
if (isset($_POST['submit'])) {
$error = "";
if (!empty($_POST['name'])) {
$name = $_POST['name'];
} else {
$error .= "You didn't type in your name. <br />";
}
if (!empty($_POST['email'])) {
$email = $_POST['email'];
if (!preg_match("/^[a-z0-9]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*
(\.[a-z]{2,3})$/i", $email)){
$error .= "The e-mail address you entered is not valid. <br/>";
}
} else {
$error .= "You didn't type in an e-mail address. <br />";
}
if (!empty($_POST['message'])) {
$message = $_POST['message'];
} else {
$error .= "You didn't type in a message. <br />";
}
if(($_POST['code']) == $_SESSION['code']) {
$code = $_POST['code'];
} else {
$error .= "The captcha code you entered does not match. Please try
again. <br />";
}
if (empty($error)) {
$from = 'From: ' . $name . ' <' . $email . '>';
$to = "mail#gmail.com";
$subject = "New contact form message";
$content = $name . " has sent you a message: \n" . $message;
$success = "<h3>Thank you! Your message has been sent!</h3>";
mail($to,$subject,$content,$from);
}
}
?>
<?php
if (!empty($error)) {
echo '<p class="error"><strong>Your message was NOT sent<br/> The
following error(s) returned:</strong><br/>' . $error . '</p>';
} elseif (!empty($success)) {
echo $success;
}
header("Location: http://example.com/pp.php#contactForm");
?>

Answer 1

You can't redirect with header() after outputting to the DOM:
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.
As such, you'll need to remove the echo statements in your lines:
if (!empty($error)) {
echo '<p class="error"><strong>Your message was NOT sent<br/> The
following error(s) returned:</strong><br/>' . $error . '</p>';
} elseif (!empty($success)) {
echo $success;
}
Before calling:
header("Location: http://example.com/pp.php#contactForm");

Answer 2

Try this:
header('Location: pp.php#contactForm');
And make sure you do not output any html tag through anyway before this line.
like the echo $success;
