  • Paste the data transfer identifier and save.
Question What payment gateways does Composr support?
Answer Composr supports PayPal, CCBill, and Authorize.Net for processing payments. While Composr could be extended to support other gateways, doing so may require professional development and customization.
Question What are the limitations for uploading large files?
Answer
  • 32-bit PHP build: Files larger than 2GB are not supported.
  • 64-bit PHP build: Files larger than 2GB are supported, but the file size will not be displayed.

For very large files, it's recommended to upload them manually and provide the URL instead of directly uploading them through the web form.
Question Can users search for specific downloads?
Answer Yes, the unified Composr search system allows users to find downloads based on keywords. This includes searching within download titles and descriptions, as well as within the content of certain file types like PDFs, text files, and even some binary formats (providing they are not too large in size).
Question Can I add images to my downloads?
Answer Yes, Composr automatically creates a gallery for each download (if the galleries addon is enabled). You can easily add images directly after creating the download or through the download-view screen. The download gallery is displayed within the download-view screen itself.
Question Are there security features to protect downloaded files?
Answer Yes, Composr includes security measures to protect downloads.
  • Protection from hackers: Uploaded files are stored with obscured filenames, preventing direct access and bypassing of the download system. Additionally, an anti-leech feature (when enabled) prevents direct download links from being shared on other websites (this is done by requiring a session ID which is validated against the person / device accessing it and only provided when Composr presents the download links to you on the site).
  • Basic security: Composr will not let anyone upload dangerous scripts (such as PHP files) which can be executed.
  • Rootkit detection: The rootkit detection tool under yourbaseurl/rootkit_detection.php can help scan files for shell scripts and backdoors. Composr's Health Check can also do this regularly. Note this only offers very basic detection and will not work for obfuscated backdoors (you should use antivirus to scan for those).

It is the responsibility of webmasters to run antivirus on their site to regularly scan files uploaded to it. Composr does not include antivirus software or virus scanning.

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.
