使用 mod_rewrite 规则后 HTML 表单在提交后未设置 `$_POST`

Question

我有 2 个简单的文件 register.php 和 user-insert.php。

register.php 文件保存 HTML 表单，方法为 POST，提交按钮命名为 submit，如下：

<form action="user-insert.php" class="contact-form" method="post">
    <ul>                         
        <li>
            <label for="who-are-you" class="first-col">Who are you?</label>
            <select name="who-are-you" id="who-are-you" class="select">
                <optgroup label="Who are you?">
                    <option value="1">Employer</option>
                    <option value="0">Employee</option>
                </optgroup>
            </select>
        </li>
        <li>
            <label for="email" class="first-col">Email</label>
            <input id="email" type="email" name="email" placeholder="name@example.com" required />
        </li>               
    </ul>
    <input type="submit" name="submit" value="Sign Up" class="btn btn-primary" />
</form>

还有user-insert.php文件：

session_start(); // tried to remove this, but It do nothing with this problem

// there checking for an errors
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

require_once("connect.php");

if(isset($_POST['submit'])) {
    // do something
} else {
    echo "POST false";
}

它总是返回我POST false。没有任何错误。只有POST 没有设置。

问题

问题在于.htaccess，如果我从该文件中删除内容，它就会开始工作。 .htaccess 现在从 www.mysite.com/any-file.php 重定向到 www.mysite.com/any-file/。也许你知道它有什么问题？

.htaccess 文件看起来像：

使用 302 重定向，重定向后不发送帖子数据。您可以使用 307 作为重定向代码来重定向帖子数据。
