Why this form submit isn't working as expected
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>

if (isset($_POST['submit'])) {
echo "posting";
}
?>
</body>
Give a name to the input:
<input type="submit" name="submit" value="submit" />
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
echo "posting";
}
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>
加载中,请稍侯......
