I have a form and I need to pass the session value via post method. I'm using the code below, but it's not working.
<input type="hidden" name="cod_usuario" value="<?php session_start(); $_SESSION['login']; ?>" class="input-medium" id="txtFuncionario" title="Nome do Funcionário"/>
First place at the beginning of your file.
<?php
session_start();
?>
Second, even though it is a session variable, to be populated in a form field, it is necessary to give ECHO to it. In your case:
<input type="hidden" id="txtFuncionario"
name="cod_usuario" value=" <?php echo $_SESSION['login']; ?>" >
