Vamos pegar algumas partes para explicar.<\/p>\n\n\n\n
O arquivo get.php mostra o formul\u00e1rio de contato:<\/p>\n\n\n\n
<?php<\/font> if<\/font> (isset<\/font>($message<\/font>)) : ?><\/font>\n <div<\/font> class=<\/font>"alert alert-success"<\/font>><\/font>\n <?<\/font>= $message<\/font> ?><\/font>\n <\/div><\/font>\n<?php<\/font> endif<\/font> ?><\/font><\/pre>\n\n\n\nSegundo, preencha os campos de entrada com dados do array $inputs. Se o campo tiver dados inv\u00e1lidos, mostre a mensagem de erro do array $errors.<\/p>\n\n\n\n
Terceiro, adicione um honeypot ao formul\u00e1rio:<\/p>\n\n\n\n
<label<\/font> for=<\/font>"nickname"<\/font> aria-hidden=<\/font>
