为什么我不能在此代码中打印$_POST的比赛？我尝试使用print_r($_POST), echo $_POST, var_dump($_POST)，但屏幕上没有显示任何内容。
这是整页：
<?php
session_start();
include("../controller/loginFuncs.php");
\asc\checkLogin();
require_once '../controller/database/MySQL_DataMapper.php';
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
try {
$mapper = \asc\MySQL_DataMapper::getInstance();
$result = $mapper->fetchAllOMs();
} catch (\Exception $e) {
echo $e->getMessage(), "\n";
}
if (isset($_POST['submit'])) {
var_dump($_SESSION);
// $militar = new \asc\Militar($_POST['cpf'], $_POST['fname'], $_POST['lname'], $_POST['organizacao_militar'], $_POST['posto']);
// $mapper->cadastrarMilitar($militar);
}
?>

到目前为止，其他所有方法都可以正常工作，现在我正尝试使用方法post获取表单的内容，并在尝试将其保存到数据库之前将其打印出来。但是什么也没显示给我。
