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 Where are download galleries located, and can I move them?
Answer By default, download galleries (to contain screenshots of a download) are placed under the root gallery. You can move them to a different gallery for better organization. Here's how:

  • Create a new container gallery (e.g., with codename "downloads").
  • Change the "Create download galleries under" configuration option to your new gallery's codename.
  • Use Commandr to move existing galleries to the new location.
Question Can I sell downloads on my Composr site?
Answer Yes, the download system integrates with the points system, allowing you to charge for downloads. This is particularly useful for communities where members create and share content, like game modifications. You can set prices for downloads and creators earn points when users purchase them. Additionally, you can create a subscription-based system by requiring points for downloads, which users can purchase via methods like PayPal.
Question What does it mean to "outmode" a download?
Answer Outmoding means marking a download as superseded or replaced by a newer version. When editing the older download, you link it to the new one in the "outmode" field. This makes it clear to users that there is a newer version available. This is handy especially if you provide software.
Question What are the different ways to add downloads to my Composr site?
Answer Composr offers several methods for adding files to the download system:

  • Uploading via web form (when adding a download in the Content Management Zone): This is the simplest method, where you attach the file directly when defining the download details. However, it's not suitable for large files and can be affected by unreliable internet connections.
  • Uploading and referencing the URL: You can manually upload the file using FTP/SFTP/SCP and then provide the URL to the file in the 'Add download' form. While this is better for large files, it requires additional
 access, and the file isn't managed directly by Composr.
  • Batch adding from an FTP server: This allows staff to add multiple downloads from an FTP server in one go using FTP URLs. It's efficient for bulk uploads but requires separate addition of descriptions.
  • Batch adding from a directory: Similar to the FTP method, staff can add downloads from a web server directory accessible by URL.
  • File/media library (filedump): Webmasters can use any of the above methods to upload a file to uploads/filedump and then reference it in a download. This is especially handy if you are going to reference the file more than once on your site.
Question What is the Composr Setup Wizard and what does it do?
Answer The Setup Wizard is a guided process to help you configure essential settings for your Composr website after installation.

It can:
  • Generate a default theme and logo
  • Set initial site options
  • Remove predefined content and unnecessary addons
  • Place initial blocks on your pages

While convenient, be aware that re-running the Setup Wizard may overwrite existing settings and customizations if you already configured your site.
Question How can I change the structure of my Composr website's pages?
Answer You can delete and move pages using the Admin Zone > Structure > Sitemap editor. However, moving pages between zones might invalidate existing page-links unless specified using the _SEARCH zone in the link.

To avoid issues with existing links and search engine indexing, consider setting up redirects when moving pages. This can be done through Admin Zone > Structure > Redirects.

It is recommended not to move default Composr pages as it can complicate future upgrades.
Question What are Installation Options and how can I change them?
Answer Installation Options are low-level settings for Composr, such as database details and default language.

You can access the Installation Options editor through:

  • The script: http://yourbaseurl/config_editor.php
  • The Admin Zone: Admin Zone > Setup > Configuration > Installation Options

Remember that you'll need your maintenance password, specified during installation, to access and modify these options.
Question How do I open or close my Composr website to the public?
Answer By default, your Composr site is closed after installation. To open it to the public (or to close an opened site), go to Admin Zone > Setup > Configuration > Site options > Closed site and adjust the setting accordingly. You can also configure a closed site message.

While a closed site prevents public access, it's worth noting that users can still join a closed Conversr-powered site if they have access to the join module URL. However, they won't be able to log in unless they're assigned to a usergroup with "Access closed site" permissions. You can modify the join module's permissions to restrict access further.
Question What is the .htaccess file and how does it relate to Composr?
Answer The .htaccess file is a configuration file for the Apache web server. It allows you to define settings that apply to the directory where it's located and its subdirectories.

Composr can leverage .htaccess to enhance security and enable features like "URL Schemes." You can try renaming the provided recommended.htaccess file to .htaccess. This file includes recommended options that tighten security and ensure Composr has necessary PHP and Apache features activated.

Note that some web hosts might restrict the use of .htaccess files.

You should regularly review recommended.htaccess for changes between Composr updates.
Question How do Composr permissions work?
Answer Composr employs a multi-layered permission system with two main types: privileges and access permissions. The system grants users the best possible access based on the combination of their usergroups.

Privileges define broad permissions, such as accessing a closed site or content manipulation abilities based on impact level (low, medium, high). You can set privileges for usergroups via checkboxes, with the option to override them for specific pages or categories. Go to Admin Zone > Security > Global privileges.

Access permissions control what content users can view. These permissions are layered:

  • Zone access permissions
  • Page (or content entry) access permissions
  • Catalogue access permissions
  • Category access permissions

To configure access permissions, you can edit the specific resource or utilize the Permissions Tree Editor under Admin Zone > Security > Permissions Tree Editor.
