Summary: Set and flush global session messages in Kirby CMS with PHP: add, display, and remove user messages using code examples for dialog popups.

## Set a global message

You can set a single message within your PHP code in the current user session. Adding new messages will overwrite any previous ones.

Code (php):  
```
kart()->message('Your message');
```

Code (php):  
```
<?php if ($msg = get('msg', kart()->message())) { ?>
    <dialog>
        <p><strong>Hi <?= kirby()->user()?->nameOrEmail() ?></strong>,</p>
        <p><?= strip_tags(urldecode($msg)) ?></p>
        <form method="dialog">
            <button autofocus><?= t('close') ?></button>
        </form>
    </dialog>
    <script defer>
        // otherwise the ::backdrop pseudo attribute will not work
        setTimeout(() => {
            document.querySelector('dialog').showModal();
        }, 100);
    </script>
<?php } ?>
```
