Add SEO Title to Articles

[nigelcopley]

This is useful when you have a page that contains multiple articles with read more as it gives you more flexibility and control over your SEO params. We've done it by extending the DCA (tl_article.php) and the Module (ModuleArticle.php) but would be useful for others as part of the core

How exactly would this work?

[nigelcopley]

Add a field into article for SEO Title

This then overrides page title when article is rendered as page. I can share the code we used to extend the moduleArticle.php with you if you want.

What if there are multiple articles?

[fritzmg]

I think he means for the detail page of an article.

[aschempp]

I guess he means if you use /…/article/alias.html url where one article is rendered.

[nigelcopley]

As fritz and andreas say it's only applicable when the article is rendered
