Question What are the different ways to target recipients for my newsletters?
Answer Composr offers several targeting options:
  • Subscriptions: Users can specifically subscribe to newsletters, separate from site membership.
  • Usergroups (Conversr only): You can send newsletters to members of specific usergroups, regardless of their newsletter subscriptions.
  • CSV imports/exports: You can import subscribers from a CSV file or export your subscriber list for custom targeting.
Question How can I prevent my emails from being marked as spam?
Answer Here are some tips to reduce the likelihood of your emails being flagged as spam:
  • Set up SPF records: SPF (Sender Policy Framework) helps verify that your server is authorized to send emails from your domain.
  • Ask users to whitelist your email address: Encourage recipients to add your email address to their contacts list or "Safe Senders" list.
  • Configure DKIM: DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, increasing their legitimacy.
  • Use a reputable email service provider: Consider using a third-party email service if you're struggling with email deliverability.
Question Why are my emails being blocked by spam filters?
Answer Several factors can cause emails to be blocked:
  • Server issues: Your server might be on a spam blacklist, or there may be problems with your server's reverse DNS or HELO settings.
  • Content issues: Your email content might trigger spam filters due to factors like an unreasonable image-to-text ratio, broken reply-to addresses, or inconsistent text and HTML versions.
  • SPF records: Your "Website email address" might be hosted on a different server with an SPF record that doesn't authorize your web server to send emails from that address.
Question How do I configure SMTP settings in Composr?
Answer Composr can use either its own SMTP connection code or PHP's built-in SMTP functionality. Using PHP's SMTP settings is generally recommended and can be managed at the server level. However, if your SMTP server requires authentication (which PHP doesn't support natively) or if your server lacks an SMTP server, you'll need to use Composr's SMTP connection code, configurable in the Configuration module.
Question How does Composr send emails?
Answer Composr constructs emails using language strings and templates written in Comcode. It sends emails in both HTML and plain text formats to ensure compatibility with different email clients. To minimize the chance of emails being marked as spam, Composr embeds CSS and images directly into the email instead of linking to them externally.
Question How can I make my website design more appealing to different thinking styles?
Answer Different individuals process information differently. Some are more visual, while others are more analytical. To appeal to diverse thinking styles, a website design should incorporate a balance of elements. For instance, using a striking header image coupled with well-structured, informative text can cater to both visual and analytical thinkers. Understanding your target audience and their thinking styles is key to creating a design that resonates with them.
Question What considerations are necessary when designing for different user levels on a website?
Answer User levels often necessitate different content or functionalities. For instance, administrators might need access to content creation tools, while regular visitors only view published content. Consider these factors during design:
  • Visibility: Some elements might need to be hidden or displayed based on user roles (e.g., admin-only links).
  • Permissions: Design elements and interactive features should reflect the permissions granted to different user levels.
  • Customization: Consider allowing users to customize their experience based on their preferences and roles.

Remember, a well-designed website should cater to all user levels while maintaining security and a cohesive experience.
Question How do I make my website theme mobile-friendly in Composr?
Answer Composr offers several features to optimize themes for mobile:
  • Mobile mode: You can design separate layouts and CSS styles specifically for mobile devices, which Composr automatically activates when a mobile user visits your site.
  • Tempcode's 0 symbol: This symbol helps conditionally display content based on whether the user is on a mobile device or desktop.
  • CSS media queries: By using media queries, you can target specific screen sizes and adjust styles accordingly, making your theme responsive.
  • Viewport meta tag: This tag controls how the browser scales and displays the webpage on mobile devices, ensuring a properly sized and zoomable experience.
Question What is responsive design, and why is it essential for mobile devices?
Answer Responsive design ensures a website adapts seamlessly to different screen sizes, providing an optimal viewing experience across devices, particularly mobile phones and tablets. It utilizes techniques like flexible grids, fluid images, and CSS media queries to adjust layout and content based on screen dimensions.

This is crucial because mobile device usage is significant, and a non-responsive site leads to a poor user experience on smaller screens, potentially driving visitors away.
Question How can I create a theme pack for release in Composr?
Answer After designing your theme, go to the admin panel's "Addons" section. You'll find an option to export your current theme as an addon. Composr will package the necessary files into a downloadable archive, ready to be shared with others or submitted to the Composr community for installation on other sites.

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.
