Why this form submit isn't working as expected

Question

I have this code in test.php .

When I access the script just by typing it, I want to see just the form
but when I click the form submit button, the next time the page loads, I want to see the form and some comment that says that the form has been submitted.

For some reason, even when I click submit, I don't get the message that it's posting. Anyone can explain why? and how can I get it to work.

<body>
    <form action="" method="post">
        <input type="text" id="inp" />
        <input type="submit" value="submit" />      
    </form>

    <?php
    if (isset($_POST['submit'])) {
        echo "posting";
    }

    ?>
</body>

Answer 1

给输入一个名字：

<input type="submit" name="submit" value="submit" />

Answer 2

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    echo "posting";
}

Answer 3

Try this:

<body>
    <form action="" method="post">
        <input type="text" id="inp" />
<input type='hidden' name='submit' value=''>
        <input type="submit" value="submit" />      
    </form>

    <?php
    if (isset($_POST['submit'])) {
        echo "posting";
    }

    ?>
</body>
