The forum base URL should be a URL prefix to your forums without a script name. For example, http://forums.example.com is correct, while http://forums.example.com/index.php is incorrect. You can fix this using the config_editor.php script and then clear the Comcode page cache.
Most Composr resources with commenting enabled create comment topics in the configured comment forum. If the forum uses BBCode, Comcode features not supported by BBCode may not display correctly. Moderate comments from the forum as you would any other topic.
It's not easy to switch forums after installing Composr. The member and usergroup IDs referenced by Composr would lose their association. Check the "Importing data into Composr" tutorial for more information on this.
Conversr is Composr's built-in forum system. It offers seamless integration, allowing you to use Comcode for forum posts, a unified Admin Zone, shared themes and templates, and innovative features like Private Topics and in-post whispers. Using a third-party forum can be clunky and may lead to maintenance headaches.
Composr supports several forum drivers, including Invision Board, phpBB, myBB, vBulletin, Burning Board, and Simple Machine Forum. If your forum is not listed, professional developers can add support. Composr also provides converters for migrating from these forums to its own forum system, Conversr.
What are the PHP requirements for running Composr?
Answer
Composr requires PHP 7.2 or higher, but versions not officially supported by PHP developers are discouraged. The maximum tested version is PHP 8.3.
Required PHP extensions:
GD2 (gd) with PNG and JPEG support
MySQL extension (mysqli or pdo_mysql)
XML extension (xml)
Multibyte String (mbstring)
cURL extension (curl)
JSON support (usually available by default)
Sodium (libsodium)
ZIP extension (zip) if ZIP file support is needed
Additional recommendations:
posix extension for permission checks
zlib extension for faster upgrades, compressed backups, and page compression
ctype extension for slightly faster performance
IMAP extension (imap) for managing newsletter bounces
OpenSSL extension (openssl) for encrypted CPFs, DKIM, and SSL certificate expiry checks
Pspell (pspell) or Enchant (enchant) extensions for spell checking
Ensure the following PHP settings are configured:
File upload size limit of at least 5MB (or higher as needed)
Maximum execution time of at least 30 seconds
Memory limit of at least 128MB
The installer will warn you if any critical functions have been disabled via disable_functions or other PHP modifications. Avoid web hosts that heavily restrict standard PHP functionality.
To uninstall Composr, access the uninstall.php file in your web browser, enter your administrator password, and follow the prompts to remove the database data. Afterward, you can safely delete the Composr installation directory.
What are the recommended web hosting options for Composr?
Answer
Choosing a web host is crucial. Avoid the cheapest options and look for hosts with recent positive reviews and minimal credible complaints. Ensure they meet Composr's requirements, including adequate disk space, no restrictive file size limits, and support for required PHP extensions.
Composr is compatible with various hosting control panels like Plesk and cPanel, and works on Windows, Linux, or Mac OS servers.
Yes, you can install Composr on a Windows desktop using software packages like WampServer, XAMPP, EasyPHP, or ampps for simplified setup. Alternatively, you can manually install Apache, PHP, and MySQL, following the instructions provided in the respective documentation. Remember to configure file permissions appropriately and ensure the webserver isn't accessible from outside your network.
How does authentication work with the server-side API?
Answer
Authentication is handled automatically using cookies, similar to regular website requests. If cookies are not feasible, the response parameters device_auth_member_id_cn/device_auth_pass_hashed_cn/device_auth_member_id_vl/device_auth_pass_hashed_vl from the login endpoint can be resent as POST parameters in subsequent requests.
How do I access the server-side API for my mobile app?
Answer
The server-side API can be accessed via HTTP calls to http://yourbaseurl/data/endpoint.php. Results are returned in JSON format. The API utilizes endpoints with a 'hook' name and a 'hook type' categorization. Both REST-style and GET-parameter style requests are supported, with the latter recommended for simplicity.
What is the purpose of the Composr Mobile SDK Toolkit?
Answer
The Toolkit, part of the composr_mobile_sdk addon, aids in mirroring Composr website resources into a mobile app. It includes tools for generating iOS/Android string resources from language files and exporting theme images in a directory structure suitable for iOS/Android app image assets.
To connect to a Composr site, you will need to install the composr_mobile_sdk addon, which is not bundled. This addon provides scripting to generate app assets from the Composr site.
Composr Mobile SDK (CMS SDK) is a toolkit designed for experienced iOS and Android developers to build mobile apps that integrate with a Composr-powered website. It offers both Composr-specific integrations and a collection of standalone utilities for building apps, providing a common base between iOS and Android akin to the PHP and Composr APIs, enabling easier code porting while maintaining a native experience.
Composr follows a rolling release model. This means:
New major/minor versions are released as they are ready.
Patch releases, primarily containing bug fixes, are only released for the latest supported major/minor version branch.
Users are responsible for staying updated to the latest release or applying necessary hotfixes.
This policy allows developers to focus resources on the latest versions and encourages users to leverage the ongoing improvements. You can find the release status on the Composr maintenance status page.
Constructive design feedback is valuable. To provide effective feedback:
Be specific and detailed. Identify particular issues and provide clear examples.
Offer solutions. Suggest improvements or provide mockups demonstrating your ideas.
Avoid vague statements. General comments like "it looks dated" are unhelpful.
Understand design constraints. Consider factors like modularity, generality, feature density, compatibility, performance, and the subjective nature of design.
Directly reporting specific design bugs to the tracker or redesigning Composr interfaces yourself are excellent ways to contribute.
Be comprehensive and self-contained. Provide all necessary information and context for the developers to understand your suggestion.
Focus on widely beneficial features. Esoteric suggestions are less likely to be implemented.
Understand developer constraints. Feature development depends on factors like developer availability, funding, and project strategy.
Consider sponsoring features. Financial contributions can prioritize the development of desired features as it affords developers the time to implement it.
