Someone could help me find my error, I thought I'd put it in the event.php $sql = "insert into produto values(0,'".$atrProduto."','".$atrPreco."',1)"; that way, but I was going to register everything in User 1, and I wanted to when I changed the session and put it, let's say a user who in id 2, the id at the time of registration appears 2 and so on. could anyone help me at this point too? I really do not have any idea what to do. I really need the help of my friends. Thank you in advance.

The error is in line mysql_query($sql,$con);

By looking at the structure of your table, we can see that the id_funcionario field is of type not null , so you should fill in a value number.

You can do:

$userId = isset($_SESSION["id"]) ? $_SESSION["id"] : 1;

$sql = sprintf("INSERT INTO 'produto' SET 'nome' = \"%s\", 'preco' = \"%s\", 'id_funcionario' = \"%d\";",
    $atrProduto,
    $atrPreco,
    $userId);

If you are still unable to register the product, use the mysql_error function below insert to view the problem.

die( mysql_error($link) );

Ps: Just remembering that mysql_ is no longer used. If possible, switch to mysqli_
