PHP: Validating Form When Routing - php

Question

I'm trying to validate a form that's being submitted through a PHP router.
All my traffic is sent to index.php via htaccess. to index.php:
RewriteEngine On
RewriteBase /router
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /divbase/index.php?/$1 [L]
index.php then provides the appropriate content:
<?php
Router::get('/form', function() {
include 'content/form.php';
});
?>
so when you go to example.com/form, the form page is loaded:
<?php
$errorMessage = false;
if (isset($_POST['submit'])) {
if (!isset($_POST['name']) || $_POST['name']=='') {
$errorMessage = 'Please enter your name';
}
else {
// do something with the data
echo "Success!!";
}
}
?>
<form method="post">
<input type="name" value="" name="name" placeholder="Your Name" />
<input type="submit" name="submit" />
</form>
<p><?php if ($errorMessage) echo $errorMessage; ?></p>
However, when I try to submit the form on that page it 404s. After doing some troubleshooting, it looks like the PHP thinks that the form is being submitted to index.php rather than form.php.
I've tried to set the form action to:
<?php "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; ?>
But it still 404s. Does anyone have any suggestions for this?

You need to add another route for POST, for example...
Router::get('/form', function() {
include 'content/form.php';
});
Router::post('/form', function() {
echo 'Hello world';
});
Your form is using method="post" so you need to add a POST route
