I am trying to send data with POST, but the result is array(0) when the var_dump function is called.

Other forms using post method with AJAX results on a correct value of the variables, and the HTML does not work.

Why could this be happening?

The form:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
      <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
      <title>Untitled Document</title>
      </head>

      <body>
      <form target="_new" enctype='application/x-www-form-urlencoded' action="include/php/produtos/romaneio/prueba.php" method="post">
      <input type="text" value="12" id="a" />
      <input type="submit" />
      </form>
      </body>
      </html>

The php:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <title>Untitled Document</title>
    </head>

    <body>
    <? var_dump($_POST);
    ?>
    </body>
    </html>

    The value of form elements will only be added to $_POST if the elements are named using name=. So, add name="d" instead of id="d".
