Setting title dynamically in component - How to?

[helmutkaufmann]

In my layout file for use in a CMS page, I have the following line

<meta name="description" content="{{ this.page.settings.meta_description | default(this.page.title) }}"/>

I would like to dynamically set this.page.settings.meta_description in a plugin's component I have written and basically set it to one of the parameters passed to the page the component is on (using input("p")). I seem not to be able where to add that to the component's code so it gets executed before the page is rendered. I have gone through the page execution lifecycle manual pages but still... to no avail.

Any help is appreciated.

@helmutkaufmann I'd recommend trying out the Winter.SEO plugin
