Question Can I display different content to different usergroups?
Answer Yes, you can achieve this by leveraging Tempcode within your templates. By using conditional statements like {$IS_IN_GROUP} and {$HAS_PRIVILEGE}, you can show or hide specific content sections based on the user's group membership or privileges. This technique allows you to "tease" premium content to non-paying users or tailor the user experience based on their access level.
Question What are match-key permissions and why would I use them?
Answer Match-key permissions provide a more granular level of access control beyond the standard zone, page, and category permissions. They allow you to restrict access based on specific "match-keys", which are unique identifiers for different actions or content within Composr. For instance, you could use match-key permissions to prevent guests from submitting banners or to restrict access to the member directory for all but specific usergroups. You can also specify custom access denied errors for each match-key.

A "match-key" is typically a page-link, such as cms:cms_banners:add.
Question How can I control who can view specific pages or categories?
Answer You can manage access control for zones, pages, and categories primarily through the Permissions Tree Editor (Admin Zone > Security > Permissions Tree Editor). This tool provides a central location to set view permissions for different usergroups. You can also edit individual zone and category permissions through their respective editing interfaces, but the Permissions Tree Editor offers a more streamlined and efficient approach.
Question What is the difference between access permissions and privileges in Composr?
Answer Access permissions control whether members of a certain usergroup can view specific areas of your site, such as zones, pages, and categories. A member only needs one of their usergroups to have access permission to view the content. But permissions work on a deny-first policy; if one of the permissions applicable to viewing something is denied for a usergroup, then the whole thing is denied for that usergroup (e.g. even if a download itself grants access, access will be denied if its category denies access).

Privileges, on the other hand, dictate what actions a usergroup is allowed to perform across the website, like using advanced Comcode or bypassing the word filter.
Question How can I change the news archive display to show summaries instead of just headlines?
Answer By default, the news archive screen shows only headlines. To display summaries like the news block, add :inline=1 to the page-link. For example, if your news archive page-link is site:news, modify it to site:news:inline=1. This will show summaries instead of just the headlines in the archive view.
Question What are Trackbacks and how do they work in Composr?
Answer Trackbacks are a blogging feature that creates a link from an article on one blog to an article on another, acting as a citation mechanism.

How Trackbacks Work:
  • The original article includes a "trackback" link in its HTML.
  • When another blogger writes an article referencing the original, their software uses the trackback link to inform the original site.
  • Composr receives the trackback and displays a list of articles linking back to the original.

To enable trackbacks, go to Admin Zone > Setup > Configuration > Feature options and check the "Trackbacks" option. You can then enable trackbacks for individual content items.
Question How can I filter the news archive to show specific content?
Answer The news system allows advanced filtering:
  • Blog vs. Non-Blog Posts: Choose to display blog posts only, regular news posts only, or both.
  • Category Filtering: Limit results to specific news categories.
  • Double Filtering: Apply a second category filter for a two-level categorization system (useful for large sites).

These filters are controlled through parameters passed to the news blocks and carried through navigation links. When viewing a news post, you can also filter by the categories associated with that post.
Question How do I display external RSS feeds on my Composr website?
Answer Composr offers two blocks for displaying RSS and Atom feeds in a news-like format:
  • main_rss block: Suitable for main content areas
  • side_rss block: Designed for sidebars and smaller spaces

To add a block, use the Block Construction Assistant or insert the following Comcode into your page:

[block="http://example.com/feed.xml"]main_rss[/block] [block="http://example.com/feed.xml"]side_rss[/block]
Replace "http://example.com/feed.xml" with the actual feed URL.

Important: Exercise caution when using external feeds. Ensure the source is trustworthy, as malicious feeds can contain harmful code.
Question What are RSS/Atom feeds and how do they benefit my website?
Answer Feeds, in formats like RSS and Atom, are XML files that syndicate your website content, making it accessible beyond your website. They can be viewed using feed reader applications (e.g., Feedly, Vienna) or integrated into other websites or web browsers.

Composr supports both RSS and Atom for syndicating news and other content. While RSS is more common, Atom is a cleaner, standardized format. Both effectively share your content updates.

Benefits:
  • Wider audience reach: Your content becomes accessible to those using feed readers and aggregators.
  • Content repurposing: Other websites can incorporate your feed, increasing visibility.
  • Increased traffic: Users discovering your content in feeds may visit your website directly.
  • Staying on top: Those who use your RSS feeds will see when you post new news articles.
Question What are Personal Categories/Blogs in Composr? How do I create one?
Answer Composr allows members of permitted usergroups to have their own personal news categories, also known as "blogs". These blogs appear as a tab on the member's profile (Conversr-only) and may also appear in the main news block depending on your configuration.

To create a blog, a member simply adds a news post and selects their personal category. If the category doesn't exist, it will be automatically created upon submission.

A dedicated "Blogs" CMS module (Admin Zone > Content > Blogs) is available if the "Separate blogs" configuration option is enabled. This simplified module focuses on blog posting and can be used to restrict members from submitting to general website news.

Question How can I customize Composr without modifying the core files?
Answer Composr offers a robust override system. Instead of altering the original files, create a parallel structure within _custom directories. For example, to modify site/pages/modules/polls.php, place your customized version in site/pages/modules_custom/polls.php.

The tutorials outline additional information on how to utilise overrides.
Question What are the main components of the Composr framework?
Answer Composr consists of:
  • Modules: PHP files that provide related screens, forming the building blocks of addons.
  • Comcode: Text files containing content written in a simplified markup language.
  • HTML: Files containing standard HTML for web pages.
  • Sources: PHP code files for the core API and functionality.
  • Hooks: PHP files enabling addons to interact and extend each other's functionality.
  • Blocks/Miniblocks: Reusable components for displaying dynamic content within pages.
  • Themes: Folders containing images, CSS, and templates to define the look and feel.
  • Language files: Files holding text strings for multilingual support.
Question How can I embed third-party widgets into my Composr pages?
Answer Composr supports embedding widgets from various websites, like Google Maps, Vimeo, and YouTube, by simply pasting the URL. For manually embedding widget code, you can paste it into the HTML source view of the WYSIWYG editor or within Comcode html tags if not using the WYSIWYG editor.
Question What is the difference between blocks and boxes in Composr?
Answer Boxes are visual elements that provide a container for content, while blocks are functional units that generate and display dynamic content. Although blocks often appear within boxes in the default templates, they are not inherently tied to any visual representation.
Question Can I customize the appearance of blocks?
Answer Yes, you can style blocks by editing the associated templates and CSS. Templates are typically named after the block they represent. For example, the main_news block uses the BLOCK_MAIN_NEWS.tpl template.
Question How do I create custom filter forms for my content?
Answer The main_content_filtering block can help you generate filter forms automatically. You can use it to create a default form and then customize the generated Filtercode string to refine the filtering options. Once satisfied, you can either continue using the block or extract the HTML and modify it further.
Question Where can I use Filtercode and Selectcode in Composr?
Answer Filtercode is supported in various blocks, such as main_multi_content, main_gallery_embed, and main_cc_embed. It's also actively used in modules like catalogues, downloads, galleries, members, and news.

Selectcode is supported in blocks and Comcode tags that explicitly mention it, including the main_multi_content block and the if_in_group Comcode tag.
Question What is the difference between Filtercode and Selectcode?
Answer Filtercode is used for querying content based on properties and values, while Selectcode is used for directly specifying a list of IDs or categories to include or exclude. Filtercode offers more complex filtering options, while Selectcode is more straightforward for simple selections.
Question How can I filter content in Composr?
Answer Composr provides two filtering systems: Filtercode and Selectcode.
  • Filtercode is used for selecting content based on defined filters, such as field values, ratings, or keywords. It utilizes a syntax of comparisons, separated by commas, where each comparison specifies a field and a matching condition.
  • Selectcode is a simpler syntax for specifying a list of IDs or categories to include or exclude from the results. It uses a comma-separated list of match-specifier tokens, such as individual IDs, ranges, or wildcard characters.
Question What are blocks in Composr and how can I use them?
Answer Blocks are dynamic elements that can be inserted into Comcode pages to add interactive and data-bound functionality to your website. They are essentially reusable components that automatically generate content, such as recent forum posts or information about the logged-in user.

You can add blocks to your pages using the block construction assistant, which allows you to select from a list of available blocks, set their parameters, preview them, and generate the necessary Comcode.
