Question How do I set the correct file permissions for Composr?
Answer If you're using the quick installer, it will handle file permissions automatically. On a suEXEC-style server, default permissions (744 for directories and 644 for files) are usually sufficient. However, _config.php should have 600 permissions for security.

Without suEXEC, specific directories (e.g., caches, uploads) and files (e.g., _config.php) require 777 (full access) or 666 (read/write) permissions. The fixperms.php script can automate this process on Linux and Windows.
Question How do I install Composr on Linux?
Answer After ensuring your web host meets the requirements and you have a database ready, you can install Composr on Linux using the following steps:
  • Upload the Composr files to your web directory.
  • Navigate to the install.php file in your web browser.
  • Follow the on-screen instructions, providing the required information, such as database details and administrator credentials.
  • After the installation is complete, delete the install.php file for security reasons.
Question What are the prerequisites for installing Composr?
Answer Before installing Composr, ensure your web host meets the minimum requirements. Familiarize yourself with your web host's control panel (e.g., Plesk, cPanel), which you'll use to manage databases, subdomains, and other settings. Gather your SFTP/FTP credentials (hostname, username, password), usually emailed upon signup. Set up a MySQL database and note its details: hostname (often 'localhost'), username, password, and database name. Ensure the database user has full read/write/administer access to the database.
Question What tools are available for debugging Composr code?
Answer Composr offers a code quality checker addon that helps identify various types of errors, including parser errors, run-time errors, and logical errors. This tool can significantly reduce debugging time and enhance code reliability. It is available through the testing_platform addon.
Question What are some key coding standards in Composr?
Answer Composr emphasizes clean, well-structured code with a focus on readability and maintainability. Key standards include proper indentation, consistent use of comments, and clear function headers with type definitions. Remember: beautiful code leads to better functionality and collaboration!
Question Where can I find resources for learning PHP programming?
Answer While Composr documentation doesn't cover basic PHP, resources like the official PHP documentation (

PHP: Hypertext Preprocessor

PHP is a popular general-purpose scripting language that powers everything from your blog to the most popular websites in the world.

), online tutorials, and the Composr API guide can help you learn.
Question What is the purpose of the Code Editor?
Answer The Code Editor is a web-based tool for editing Composr code files directly on the server. It requires password authentication and automatically manages overrides within _custom directories.

To access it, go to yourbaseurl/code_editor.php.
Question How can I export and import custom addons?
Answer Composr allows exporting addons as TAR files, containing all necessary files and an addon.inf file for metadata. You can import these addons to share and reuse them across different Composr installations.

To do this, make your necessary files for the addon in the Composr installation, and then go under Admin Zone > Structure > Addons > Export addon. You can select the relevant files for the addon, provide information about the addon, and then download the TAR file (which can then be imported on other Composr sites).
Question Can you give an example of creating a new module?
Answer Imagine creating a "Testing" module to manage collaborative testing:
  • Define purpose: Allow testers to add, assign, and track tests, with security and forum integration.
  • Design database: Plan the necessary database tables and fields to store the module's data.
  • Create module shell: Write the basic module structure based on standard Composr modules.
  • Define screens: Identify the module's screens and code their corresponding functions.
  • Utilize API functions: Use Composr's built-in API functions like create_table, add_privilege, and do_template to implement functionality.
Question What are the different ways to extend Composr functionality?
Answer You can extend Composr through:
  • File overrides: Replacing existing source files with modified versions in _custom directories.
  • New Modules/Mini-modules: Creating new modules for complex functionalities or mini-modules for simpler ones.
  • New Blocks/Miniblocks: Adding reusable content blocks.
  • New API code: Adding new PHP files to the sources_custom directory.
  • Hooks: Writing hooks to add features to specific areas of functionality.

Question How can I improve my search results?
Answer Here are some tips for improving search results:
  • Use specific keywords: The more specific your keywords, the better your results.
  • Use boolean operators: Use "+", "-", and quotation marks to refine your search.
  • Optimize content titles and meta keywords: These fields are given priority during search, so make sure they accurately reflect your content.
  • Consider enabling the fast custom index: Especially beneficial for large websites or frequent filtered searches.
Question What is the fast custom index and why should I use it?
Answer The fast custom index is Composr's own search engine, designed to be faster and more efficient than MySQL full-text search, especially for large websites and filtered searches.

Benefits of the fast custom index:
  • Faster filtered searches: Significantly improves search speed when you add filters like category or author.
  • Configurable stop words: Control which common words are ignored during search.
  • Better stemming: More accurately recognizes variations of words (e.g., "like" and "liking").
  • Multilingual support: Indexes content based on different language translations.

Downsides of the fast custom index:
  • Slight lag in indexing new content: New content takes a short time to be indexed.
  • Less accurate ranking: Ranking is based on the most obscure keyword, not a blend of all keywords.
  • Cannot perform blank searches: You must enter at least one keyword.
Question Can I filter my search results?
Answer Yes, you can filter your search results by:
  • Content type: Choose to search specific content types like news, forum posts, or Comcode pages.
  • Author/Submitter: Search for content submitted by a specific member.
  • Date: Limit your search to content submitted within a specific time frame.
  • Category (for certain content types): Narrow down your search to specific categories within a content type.
Question What is the difference between natural and boolean searching?
Answer Natural search is a more relaxed approach where you type in your search terms and Composr tries to find the most relevant results, even if they don't contain all the words. It's like a Google search.

Boolean search requires more precision and uses operators like "+", "-", and quotation marks to define exactly what you're looking for. For example, searching for "+car -maintenance" will only return results that contain the word "car" but not "maintenance".
Question How do I search my Composr website?
Answer There are a few ways to search your Composr website:
  • Using the search bar in the header: This is the simplest way to search. Just type your search term in the box and click the search button.
  • Using the 'Search' module: This module offers more detailed search options. You can access it via the 'site:search' page-link (usually under About > Search in the default menu).
  • From the Forum: Click the 'Search' button on the forum or use the contextual search box on the forum member bar. This will search within your current forum or topic.
Question How do I mark correct answers in a quiz?
Answer For questions with predefined answers, you can mark correct answers by adding [*] after the answer. If no answer is marked correct, the question will require manual marking. You can also use the [UNMARKED] tag after a question to exclude it from scoring.
Question What is the input syntax for quiz questions?
Answer Quiz questions are inputted in blocks, separated by blank lines. The first line is the question, followed by potential answers on subsequent lines. Different question types are indicated by tags after the question, such as [MULTIPLECHOICE], [MULTIMULTIPLE], [LONG], [SHORT], and [SHORT_STRICT].
Question Can I create complex, multi-screen quiz interfaces in Composr?
Answer While Composr's built-in quiz system is excellent for standard formats, creating intricate multi-screen quizzes might require custom development using Composr's decision tree framework or other programming tools. This allows for highly customized quiz structures and advanced branching logic.
Question How can I analyze quiz results effectively?
Answer Composr enables you to export quiz results to a spreadsheet file, facilitating in-depth data analysis. This is especially useful for manually marked questions, identifying competition winners, and processing data for marketing or research purposes.
Question What are Quiz Sets and how can I use them?
Answer Quiz Sets are a helpful organizational feature in Composr. By prefixing quiz names with "Example: ", you can group related quizzes together. This allows for combined scoring and percentage calculations, particularly beneficial for multi-part questionnaires or tests.
