opeta,

I ran some tests here and I think I figured out the problem. If you notice, only your values of the kind String are not being sent. This is because you are using the +descricao instead of descricao.

Run a test, assign a string to a variable and run the expression +variavel, the return will be NaN.

So for your code to work, just remove the +:

 function SalvarRegistro(){
    $(this).ready(function(){
        var cursodisciplina_id = $("#disciplina option:selected").val();
        var descricao = $("#disciplina option:selected").text();
        var link = $("#link").val();
        var usuario_lancamento = $("#usuario_lancamento").val();
        var adicionar = 1;

        $.ajax({
            type: "POST",
            dataType: "json",
            url: "cursodisciplinaemena_acao.php",
            data: {cursodisciplina_id: cursodisciplina_id, descricao: descricao, link: link, usuario_lancamento: usuario_lancamento, adicionar: adicionar},
            success: function(data) {
                    alert(data[0].msg);
            },
            failure: function() {
            alert("Ocorreu um erro, tente novamente!");
            }
        });
});
return true;
