Combine Controllers for 'Contact' page and 'Site'

1

I have an ‘Site’ Controller for managing SEO:

<?php
return function ($page, $kirby, $site) {
  $seo = $kirby->controller('seo' , compact('page', 'site', 'kirby'));
  // Override Meta Title
  $metatitle = $page->seotitle();
  $data = compact('metatitle');
  return a::merge($seo, $data);
};

On my Contact page I have a controller to manage the contact form.

<?php
return function($kirby, $pages, $page, $site) {
  

    $alert = null;

    if($kirby->request()->is('POST') && get('submit')) {

        // check the honeypot
        if(empty(get('website')) === false) {
            go($page->url());
            exit;
        }

        $data = [
            'name'  => get('name'),
            'email' => get('email'),
            'tel' => get('tel'),
            'text'  => get('text')
        ];

        $rules = [
            'name'  => ['required', 'minLength' => 3],
            'email' => ['required', 'email'],
            'tel' => ['required', 'minLength' => 11],
            'text'  => ['required', 'minLength' => 3, 'maxLength' => 3000],
        ];

        $messages = [
            'name'  => 'Please enter a valid name',
            'email' => 'Please enter a valid email address',
            'tel' => 'Please enter a valid telephone number',
            'text'  => 'Please enter a text between 3 and 3000 characters'
        ];

        // some of the data is invalid
        if($invalid = invalid($data, $rules, $messages)) {
            $alert = $invalid;

            // the data is fine, let's send the email
        } else {
            try {
                $kirby->email([
                    'template' => 'email',
                    'from'     => 'website@moore-dm.co.uk',
                    'replyTo'  => $data['email'],
                    'to'       => 'david@moore-dm.co.uk',
                    'subject'  => esc($data['name']) . ' sent you a message from your website contact form',
                    'data'     => [
                        'text'   => esc($data['text']),
                        'sender' => esc($data['name']),
                        'tel' => esc($data['tel']),
                        'email' => esc($data['email'])
                    ]
                ]);

            } catch (Exception $error) {
                if(option('debug')):
                    $alert['error'] = '<span class="error">The form could not be sent: <strong>' . $error->getMessage() . '</strong></span>';
                else:
                    $alert['error'] = '<span class="error">The form could not be sent!</span>';
                endif;
            }

            // no exception occurred, let's send a success message
            if (empty($alert) === true) {
                $success = '<span>Your message has been sent, thank you. We will get back to you soon!</span>';
                $data = [];
            }
        }
    }
    
    return [
        'alert'   => $alert,
        'data'    => $data ?? false,
        'success' => $success ?? false
    ];
};

How can I add / combine the Site SEO controller to my contact page Controller?

See: Shared Controllers | Kirby CMS

Personally, I would move this logic into a plugin.

The SEO controller is from a plugin I downloaded. The contact Controller is from your tutorial. Email contact form | Kirby CMS

However, I don’t know how I can use the two controllers together. It’s a shame I can just add them like snippets.

But in your contact controller you can do it in the same way as you merge them in your site controller where you already merge the seo controller?
