PHP form fills with ones after submission - php

Question

I am stumped....
I have created a PHP form to gather some user information and email it to the site owner, after the form is submitted, the fields auto complete with a '1' I am assuming this means the field was true and submitted.
Does anyone have any suggestions on how to hide or remove the 1 after the form is submitted? I just want the form to be blank after submission. Here is the code, Sorry for the poor formatting and eye bleeding wall of code.
Thank you in advance for any help!
PHP Code
$errName = "";
$errcatBreed = "";
$errEmail = "";
$errMessage = "";
$result = "";
if (isset($_POST['submit'])) {
$name = $_POST['name'];
$catBreed = $_POST['catBreed'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'PearTreeHill Contact Form';
$to = 'test#domain.com';
$subject = "New furbaby enquiry from $name";
$body ="From: $name\n Cat Breed: $catBreed\n E-Mail: $email\n Message:\n $message";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Please enter your name';
}
// Check if cat breed has been entered
if (!$_POST['catBreed']) {
$errcatBreed = 'Please enter either Ragdoll or British ShortHair';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Please enter a valid email address';
}
//Check if message has been entered
if (!$_POST['message']) {
$errMessage = 'Please enter your message';
}
// RECAPTCHA
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response']))
{
$secret = 'Private Key';
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
$responseData = json_decode($verifyResponse);
if($responseData->success)
{
$succMsg = 'Your contact request have submitted successfully.';
}
else
{
$errMsg = 'Robot verification failed, please try again.';
}
}
// If there are no errors, send the email
if (!$errName && !$errcatBreed && !$errEmail && !$errMessage) {
if (mail ($to, $subject, $body, $from)) {
$result='<div class="alert alert-success">Thank You! I will be in touch</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again.</div>';
}
}
}

Answer 1

<?php echo htmlspecialchars(isset($_POST['email'])); ?>
Here you display the result of isset() (TRUE or FALSE).
You should do :
<?php if ( isset($_POST['email']) ) echo htmlspecialchars($_POST['email']); ?>
And this for each field :-)

Answer 2

change
echo htmlspecialchars(isset($_POST['name']));
to
echo htmlspecialchars ($_POST['name'])
I mean remove isset();
