Hi RainLab, Prompt how to display the contents of the "Excerpt" in "meta=Description" on page post?

Hi, try this:

{{ blogPost.excerpt }}

Sorry, I just realized that you wanted to know how to display it in the meta tag. There is a solution for it. Use the onEnd() function in the page PHP section to access the loaded post object. Load the excerpt from the post and inject it to the page as a new variable:

function onEnd()
{
    if (isset($this['blogPost'])) {
        $this->page->title = $this['blogPost']->title; // Example - override the page title
        $this['metaDescription'] = $this['blogPost']->excerpt;
    }
}

Example page (or layout) HEAD tag contents:

<head>
    ...
    <title>{{ this.page.title~' - October CMS' }}</title>
    <meta name="description" content="{{ metaDescription }}">
    ...
</head>

If I'm using
{% component 'blogPost' %}
on Markup side to render it's contents, how can I access it in Code section on the same page?
in onEnd() function isset($this['blogPost']) returns false
