When I click submit in the form, I wanted it to validate the fields, with PHP, but not reload the page.
I’m using this code:
<?php
if (isset($_POST["submit"])) {
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$human = intval($_POST['human']);
$from = 'Contato do site';
$to = 'giovanni@';
$subject = 'Formulário de contato - ';
$body ="Enviado por: $name\n E-Mail: $email\n Menssagem:\n $message";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Por favor, insira o seu nome';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Por favor, insira um endereço de e-mail válido';
}
//Check if message has been entered
if (!$_POST['message']) {
$errMessage = 'Por favor, insira a sua mensagem';
}
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage) {
if (mail ($to, $subject, $body, $from)) {
$result='<div class="alert alert-success">Obrigado! Entraremos em contato em breve!</div>';
} else {
$result='<div class="alert alert-danger">Desculpe, houve um erro ao enviar a sua mensagem. Por favor tente de novo mais tarde.</div>';
}
}
}
?>

I usually leave in another page PHP and call by the action, but I decided to leave everything in one page to see if it worked, but it did not work.
Good afternoon Giovanni, you know what ajax is?

@Guilhermenascimento I know, but I would give me about 30% of notion about ajax. But you can say there William, that I run behind knowing!!

To do the validation on the same page it is necessary that the validation is done by javascript without necessarily sending the data. For this there are plugins that do the validation task, I use quite the validate jquery -> http://jqueryvalidation.org/ which is very good. Take a look at it.

Ajax does not refresh the page as @Guilhermenascimento said
