Form submission data not reaching PHP script using custom Driver file

[adaptpatrick]

Hi Valet community,

I'm encountering what seems to be a very bizarre issue related to POST data from a form submission being cleared after the request passes through our custom Driver.

The background

I have a bespoke PHP CMS project that we've adopted from a client. This CMS uses Apache URL rewrites to handle routing. As Valet uses Nginx under the hood instead of Apache, the rules present in the .htaccess file don't run.

What I've done so far

In order to recreate the URL rewriting effect in Valet, I've created the following custom Driver:

<?php

class MintCMSValetDriver extends ValetDriver
{
	/**
	 * Determine if the driver serves the request.
	 *
	 * @param  string  $sitePath
	 * @param  string  $siteName
	 * @param  string  $uri
	 * @return bool
	 */
	public function serves($sitePath, $siteName, $uri)
	{
		return is_dir($sitePath . '/mint-admin');
	}

	/**
	 * Determine if the incoming request is for a static file.
	 *
	 * @param  string  $sitePath
	 * @param  string  $siteName
	 * @param  string  $uri
	 * @return string|false
	 */
	public function isStaticFile($sitePath, $siteName, $uri)
	{
		if (
			file_exists($staticFilePath = $sitePath . $uri) &&
			!is_dir($sitePath . $uri) &&
			pathinfo($sitePath . $uri)['extension'] != 'php'
		) {
			return $staticFilePath;
		}

		return false;
	}

	/**
	 * Get the fully resolved path to the application's front controller.
	 *
	 * @param  string  $sitePath
	 * @param  string  $siteName
	 * @param  string  $uri
	 * @return string
	 */
	public function frontControllerPath($sitePath, $siteName, $uri)
	{
		if ($this->requestIsAdmin($uri)) {
			return $sitePath . '/mint-admin/index.php';
		}

		if (file_exists($sitePath . $uri)) {
			return $sitePath . $uri;
		}

		if ($uri !== '/') {
			$_GET['quer'] = substr($uri, 1);
		}

		return $sitePath . '/index.php';
	}

	private function requestIsAdmin($uri)
	{
		return strpos($uri, '/admin') !== false;
	}
}

The issue I'm experiencing

You'll notice in my frontControllerPath method, I'm checking to see if the URI is attempting to resolve to a file directly using the following logic:

if (file_exists($sitePath . $uri)) {
	return $sitePath . $uri;
}

This works successfully & routes the form submission through to the intended PHP script. However, I'm finding that the form data (accessed via $_POST) whilst able to be read in my frontControllerPath method, doesn't reach the final PHP script. $_POST gets emptied after it's routed by the custom Driver.

When running the following inside the if conditional statement above:

echo '<pre>';
print_r($_POST);
die;

We get the following output (values of keys changed to 'xxx' for security purposes):

Array
(
    [crossCheck] => xxx
    [crossCheck2] => xxx
    [crossCheck3] => xxx
    [name] => xxx
    [pass] => xxx
    [login] => xxx
)

However running this in the PHP script & resubmitting the form (to ensure the request doesn't change to a $_GET), we just get an empty array:

Array
(
)

Other things I can confirm:

• The request method being used to access the PHP script is still a "POST"
• "GET" params can be set in the custom Driver and accessed in the PHP script but not "POST"
• Submitting the initial form with a method of GET does result in the data reaching the final PHP script. So this issue seems to relate to POST data only. 🤨

Bump... Any chance anybody has experienced something similar with this & may be able to help? 🙏

So it turns out my sleep deprivation after recently having a child was the culprit on this occasion. 🙄🤦‍♂️ The issue had nothing to do with Valet & it was in fact at the application layer where the $_POST data was being emptied. 😑

There's at least 2 days of my life I'm not getting back! 😩
