Gentlemen, I have a problem sending data to the database, because it is learning and testing (first time I connect to the database and send data) I will leave, servername,database,username,.

in the briefcase Uvidoria, I took a form in which I saw in that post in Stackoverflow I created the same database as his because it is the same thing I want to do (I want to get comments and complaints about the site) so I left the same as his changing only the last line (testimony, for comment)

ultima imagem do post é o erro que aprensenta depois de clique em enviar

The files are all in the same folder (in the /public_html) as shown in the image below follows the page Ouvidoria.html where is the client’s fill

Follow what you have in the connection2.php file (where you have password and user and location)

<?php
//verifica se existe conexão com bd; caso não tenta, cria uma nova
if ((isset($_POST['email'])) && (!empty($_POST['email']))) {

    //porta, usuário, senha, nome data base
    //caso não consiga conectar mostra a mensagem de erro mostrada na conexão
    $conexao = mysqli_connect("localhost", "id3774441_test123", "teste", "id3774441_test") or die("Erro na conexão com banco de dados " . mysqli_error($conexao));

    //Abaixo atribuímos os valores provenientes do formulário pelo método POST
    $nome = $_POST['nome'];
    $email = $_POST['email'];
    $comentario = $_POST['comentraio'];

    $string_sql = "INSERT INTO teste (id,nome,email,comentario) VALUES (null,'$nome','$email','$comentario')";
    $insert_member_res = mysqli_query($conexao, $string_sql);
    if (mysqli_affected_rows($conexao) > 0) { //verifica se foi afetada alguma linha, nesse caso inserida alguma linha
        echo "<p>reclamacao Registrado</p>";
        echo '<a href="index.html#sobre">Voltar para formulário de cadastro</a>'; //Apenas um link para retornar para o formulário de cadastro
    } else {
        echo "Erro, não foi possível inserir no banco de dados";
    }
    mysqli_close($conexao); //fecha conexão com banco de dados
} else {
    echo "Por favor, preencha os dados";
}
?>

Check that the connection parameters are, https://www.php.net/manual/en/mysqli.construct.php . In order, host, username, passwd, db_name.

My dear, to find the error, I recommend treating by pieces, until I identify the real problem.

Write only one echo "Hello word"; in your connection2.php file.
Check if the form redirect URL is correct.

After this simple 'Hello word' is displayed on the screen, you can check if the form is being sent with a var_dump($_POST). If the form is sent normally, do all your processing of the form and display your message.

Not running from your code, something like:

if ((isset($_POST['email'])) && (!empty($_POST['email']))) {
   echo "Formulário enviado com sucesso";
} else {
    echo "Por favor, preencha os dados";
}

If everything worked, validate your connection to the database and run the query without depending on variables.

$conexao = mysqli_connect("localhost", "id3774441_test123", "teste", "id3774441_test") or die("Erro na conexão com banco de dados " . mysqli_error($conexao));

$string_sql = "INSERT INTO teste (id,nome,email,comentario) VALUES (null,'teste','teste','Testando insert')";
$insert_member_res = mysqli_query($conexao, $string_sql);

if (mysqli_affected_rows($conexao) > 0) {
    echo "Inserido com sucesso".
} else {
    echo "Erro, não foi possível inserir no banco de dados";
}

Well, I believe that validating step by step what happens in your application will be better to identify and treat your error.
