如何防止非法提交请求?

I am new to PHP so as I am learning I just discovered that you can go directly to a page like domain.com/process.php and the page would still run.

How can I prevent a user from directly accessing the page and make sure they got to the process.php after they have submitted the form?

    Simply, use this code :

    <?php
    if(!isset($_POST['submit']))
    {
    echo 'Try accessing this page by pressing submit button'. '<br />';
    echo "<a href='form.html'>Goto Form Page</a>";
    exit();
    }
    ?>
    
    // here 'submit' is the name attribute within your input tag for submit button
    /*
    It simply means if submit button is not pressed, echo the following message and 
    exit don't run anything else. You can also use die('Your message here') 
    instead of exit();
    */
