Send user name in SESSION with form

Question

I am sending a form as follows:

After uploading the video, I would like the uploaded video table to include the name of the uploaded user as well.

I tried with post and get method as follows:

$monitor = $_GET["nomecomp"];

However, the Undefined Index.

Anyway, how can I pull php’s SESSION username, and send it to mysql through:

$sql_logar = "INSERT INTO video_monitor (titulo_video, disciplina, link_video, coment_video, arquivo, data, monitor)
      VALUES ('$nome_video', '$disciplina', '$link_video', '$coment_video', 'Nenhum arquivo', NOW(), '$monitor')";

Answer 1

If the user data is written to variables in the Session, you can for example send the data to the code that runs the Insert in the table like this for example:

<form action="" method="post">

<!-- AQUI OS CAMPOS DO SEU FORMULÁRIO -->

<input id="id_usuario" name="venda['id_usuario']" type="hidden" class="form-control" value="<?php echo $_SESSION['id_usuario']; ?>">

<input id="nome_usuario" name="nome_usuario" type="hidden" class="form-control" value="<?php echo $_SESSION['nome_usuario']; ?>">

</form>
