How to create a PHP form that submits to itself?
Question:
How to create a self-posting/self-submitting form, i.e. one that submits the results to itself rather than to another form ?
Answer:
The correct approach is to use $_SERVER["PHP_SELF"] (in combination with htmlspecialchars to avoid possible exploits). You can also skip the action= part if it's empty, which is invalid in the W3C but currently works in most (all?) browsers - by default, if it's empty, commit to itself.
Here is an example form that gets a name and email and then displays the value you entered after submission:
<code class="php"><?php if (!empty($_POST)): ?>
Welcome, <?php echo htmlspecialchars($_POST["name"]); ?>!<br>
Your email is <?php echo htmlspecialchars($_POST["email"]); ?>.<br>
<?php else: ?>
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
Name: <input type="text" name="name"><br>
Email: <input type="text" name="email"><br>
<input type="submit">
</form>
<?php endif; ?></code>The above is the detailed content of 以下是幾個可能的標題： * How to Create a Self-Submitting PHP Form? * How to Make a PHP Form Submit to Itself? * How to Create a PHP Form That Posts Back to Itself? * How to Create a PHP Form That Submits Data t.

How do I destroy a session in PHP using session_destroy()?
Jun 20, 2025 am 01:06 AM
To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
