Hi there,

For a project, I’ve created global fields like “maximum respond date,” “average shipping date,” and “fee,” etc. in site.yml

Now, I need to build out the terms and conditions, as well as some legal pages, and reference these variables throughout the text.

In the legal.yml file, I have a text area.

My question is: how can I ensure that {{ site.shipping\_date }} is populated with the actual value?

For example, here’s what my panel text looks like:

`We are pleased to inform you that your order will be shipped by {{ site.shipping_date }}. Please ensure that you are available for delivery on or after this date. Thank you for choosing us!`

However, I’m having trouble figuring out how to get it to display the actual value. I perfectly can see all the markup bold, italic, lists, etc… but not the actual Shipping\_date or other variables.

In my legal.php file, I’m using, so it keeps the styling of the textarea:

`<?= $page->text()->kt() ?>`

Any insights would be greatly appreciated!

Thanks.

In a `textarea` field that you display in the template via `->kt()` you could use a custom [Kirbytag](https://getkirby.com/docs/reference/plugins/extensions/kirbytags) to achieve want you’re after.

Within your Kirbytag you can basically program whatever you want to happen.

You can use Str::template to replace those placeholders

> Use placeholders for recurring text snippets and more

Thank you both, after some experimentation, placeholders seems the way to go. I will experiment later with tags!

Thank you!

Thank you.  
Good to know about kirbytags. However I will probably go with placeholders as it is easier to define in the panel. I have this client that wants to change basically everything themselves for those legal pages.

All the best.

Great! It might be interesting to know about `i18n::template()` too, in case the website needs to be multilingual!
