Retrieving Articles Outside of Articles
Articles are stored as Resources in MODX, allowing you to easily utilize them in other MODX Extras. The only thing to note is that Articles have "hidemenu" set to 1 (they are hidden from menus) by default - the reason being to prevent them from showing in menus across your site (Imagine a site with 10,000 Articles - that'd be a big menu!).
For example, this getResources call grabs the latest 8 Articles for you in your Container with ID 10:
[[getResources? &parents=`10` &tpl=`myTpl` &showHidden=`1` &limit=`8` ]]
That's all there is to it!
The Articles Snippet
Articles 1.4+ comes with a snippet called "Articles" that you can use to get Articles-specific placeholders for a Container on any Resource in your site. For example, putting this call on your Home page, targeting the Container with ID 10:
[[Articles? &container=`10`]] [[+latest_posts]]
...will show the latest Articles posts for that Container. The snippet makes available all the placeholders in the default Template, which are:
[[+latest_posts]]- This shows the "Latest Posts" widget on the right-hand side of the sample template.
[[+latest_comments]]This shows the "Latest Comments" widget on the right-hand side of the sample template.
[[+comments_enabled]]This will be 1 or 0, depending on if you enabled comments for this container.
[[+tags]]This shows a list of the most commonly used tags across your blog.
[[+archives]]This shows a list of the latest months (or years) in archive format that you've made posts to.
Also, you can use the &placeholderPrefix property on the Articles snippet to add a prefix to the above placeholders, allowing you to have multiple Articles snippet calls on one page.
