I'm trying to create a theft to automate a process, as post here: Automate process - Robot?

Given the suggestions, I'm following using cURL. What is happening is the following: It manages to login, goes to the second page where the form is that I want the POST to be done but it does not return anything to me. My question is if I have to use some command that saves the login session. Because of what I'm seeing it is returning a link that displays User and invalid password or Invalid Session in the second POST. Here is my code:

    // Inicia o cURL
   $ch = curl_init();

// Define a URL original (do formulário de login)
curl_setopt($ch, CURLOPT_URL, 'http://site.com/consulta/index.php');

// Habilita o protocolo POST
curl_setopt ($ch, CURLOPT_POST, 1);
// Define os parâmetros que serão enviados
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'usuario=teste&senha=teste');
// Imita o comportamento patrão dos navegadores: manipular cookies
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
// Define o tipo de transferência (Padrão: 1)
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
// Executa a requisição
$store = curl_exec ($ch);

// Define uma nova URL para ser chamada (após o login)
curl_setopt($ch, CURLOPT_URL, 'http://site.com/consulta/forms.php');
// Habilita o protocolo POST
curl_setopt ($ch, CURLOPT_POST, 1);
// Define os parâmetros que serão enviados
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'campoNome=Joao');

// Executa a segunda requisição
$content = curl_exec ($ch);

//show information regarding the request
print_r(curl_getinfo($ch));
echo curl_errno($ch) . '-' . 
                curl_error($ch);

// Encerra o cURL
curl_close ($ch);

If I put an echo of the $ content exits the form page, but without any information or typed fields ..

You do not reuse cookies and therefore do not have the correct answer. One tip is to create methods for each type of request, where they will reuse cookies:

function getRequest($url, $myCookieFile) {
    $ch = curl_init();
    curl_setopt_array($ch, [
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_COOKIEJAR => $myCookieFile,
        CURLOPT_COOKIEFILE => $myCookieFile
    ]);

    $response = curl_exec($ch);
    return $response;
}

function postRequest($url, $data, $myCookieFile) {
    $ch = curl_init();
    curl_setopt_array($ch, [
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => $data,
        CURLOPT_COOKIEJAR => $myCookieFile,
        CURLOPT_COOKIEFILE => $myCookieFile
    ]);

    $response = curl_exec($ch);
    return $response;
}

With the methods implemented above you can maintain session persistence between pages. An example usage would be as follows:

// Primeira requisição para postar data e ter minha sessão
postRequest('http://site.com/sessao-para-pegar-os-cookies', 'usuario=teste&senha=teste', 'cookies.txt');

// Segunda requisição com os cookies da primeira requisição
$resposta = getRequest('http://site.com/pagina-para-usuarios-autenticados', 'cookies.txt');
