Question How do I set up the system scheduler in Composr?
Answer The system scheduler is crucial for scheduled tasks like sending notifications, running backups, and processing reports. To set it up, you need to schedule a system-level task to run the data/cron_bridge.php file at least every 10 minutes. This links Composr's scheduler with your server's scheduler (like Cron on Linux).

Composr can often detect the correct command to use for your setup. You can check by visiting http://yourbaseurl/data/cron_bridge.php?query_mode=1, which should display the suggested Cron command. Note that you may need to replace the php command with the absolute path to PHP if you cannot use the php command directly.

If your hosting doesn't support Cron or scheduled tasks, you can enable scheduled tasks to run when visitors access your site. Navigate to Admin Zone > Setup > Configuration > Performance options and check "Web requests run scheduled tasks". Keep in mind that this method relies on visitor traffic and isn't as reliable as a dedicated scheduler.

Alternatively, consider using external services like EasyCron, setcronjob.com, or onlinecronjobs.com. These services allow you to schedule calls to the data/cron_bridge.php script by URL at specified intervals.
Question What are the different security levels in Composr's Setup Wizard and what do they affect?
Answer Composr offers five security levels in the Setup Wizard: Minimum, Low, Medium, High, and Ultra High. Each level sets various security configurations that you can later customize under Admin Zone > Setup > Configuration.

The security levels influence settings such as:

  • Content Security Policy
  • Session expiry time
  • Password reset process
  • Password expiry days
  • Minimum password length and strength
  • Login error secrecy
  • IP strictness for sessions
  • Cryptographic ratchet
  • CAPTCHA usage
  • Brute force threshold
  • Audio CAPTCHA
  • URL Monikers
  • .htaccess restrictions on maintenance scripts
  • Enquiry on new IP addresses

The higher the security level, the more stringent the security measures, with Ultra High offering the most robust protection but the most potential inconvenience to users.

Generally, you should use these settings depending on your site:
  • Minimum: Very bare-bones informational-only sites
  • Low: Sites which do not allow public registrations and do not use eCommerce but have content managed by different staff, and are not concerned with privacy or data
  • Medium: Sites with social features / public accounts but do not use eCommerce.
  • High: Sites which use eCommerce.
  • Ultra High: Sites containing very sensitive data, such as but not limited to cybersecurity sites, government departments, banks, healthcare, etc.
Question How do I change my website's logo?
Answer You can change your site's logo manually or by using the Logo Wizard. To change it manually, go to Admin Zone > Style > Themes. Choose "logo/-logo" from the dropdown list, which represents the logo for the Welcome Zone and any zone without a specific logo. Replace the current image by uploading a new .jpeg, .gif, or .png file. Ensure that the 'Name' field remains unchanged.
Question What are Composr addons and how do I manage them?
Answer Composr is built using a series of addons that provide different functionalities. All "bundled" addons are installed by default. Once you are familiar with Composr, it's recommended to remove any bundled addons you don't need to simplify your site and prevent accidental exposure of unconfigured features to visitors (the Setup Wizard can also uninstall these addons based on your preferences). You can manage addons by navigating to Admin Zone > Structure > Addons. Uninstalled addons are archived and can be restored later, but any associated data will be permanently lost.

Composr also offers non-bundled addons. These addons are not bundled because they are not considered mainstream, rely on third-party services, haven't been vetted to Composr standards, or don't fully conform to those standards.

You can install non-bundled addons by going to Admin Zone > Structure > Addons, scrolling to the bottom and clicking "Import non-bundled addon(s)". You will need to browse to the addon file and click the import button. Once imported, review the warnings and proceed to install the addon.

You can also download and import addons from this website under the Downloads section.
Question What are some of the default Comcode pages in Composr?
Answer Composr includes several default Comcode pages, each serving a specific purpose:

  • home (Welcome and Site zones): The default front pages for the respective zones.
  • sitemap (Welcome zone): Displays the sitemap, typically generated automatically.
  • _rules (Welcome zone): Outlines the site rules, also displayed during registration. The "rules" page (no underscore) is a wrapper for this page.
  • privacy (Welcome zone): Provides privacy policy information. By default, this is generated automatically with Composr's privacy policy generator block.
  • 404 (Welcome zone): The page shown for 404 errors (page not found) and includes a sitemap.
  • help (Site zone): Contains general help information.
  • userguide_comcode (Site zone): A basic guide to Comcode for users.

Remember that you can edit these default pages or create entirely new ones to tailor your site's content to your specific needs.
Question How do I hide a Comcode page from the sitemap?
Answer If you want to prevent a Comcode page from appearing in your sitemap, you can simply prefix its name with an underscore (_). For example, pages named "_test" or "_example" would be excluded from the sitemap. Note that this generally does not hide the page from your site itself (to do that, use the validation addon to turn validated to "OFF" for the pages); it only hides them from the sitemap / search engines.
Question Can I organize Comcode pages in a hierarchical structure?
Answer Yes, Composr allows you to simulate a hierarchical structure for your Comcode pages using multi-part paths in the page monikers. By editing the page monikers to include slashes (e.g., "about/team"), you can create a virtual directory structure within a single zone, enhancing your site's organization and navigation.
Question How do I embed content from other modules into a Comcode page?
Answer You can use various blocks to embed content from different modules:

  • main_content block: Allows you to feature individual entries from modules/content like news or articles.
  • main_multi_content, main_cc_embed, main_gallery_embed, main_news blocks: Enable you to pull in and display multiple entries based on categories or other criteria.
  • main_include_module block: Provides a powerful way to integrate any module screen directly into a Comcode page.
Question What is the difference between blocks and boxes in Composr?
Answer While both terms may seem similar, they have distinct meanings in Composr:
  • Blocks are functional units that generate dynamic content or provide specific features. They don't inherently have a visual form and their output can vary widely.
  • Boxes are a visual design element in Composr, essentially containers that visually group content on a page and often with a title at the top.

In practice, blocks often place their content within a box, but this isn't a requirement / standard.
Question Can I customize the appearance of blocks?
Answer Yes, you can customize the appearance of blocks by editing the associated templates and CSS. Each block typically has a corresponding template file (e.g., BLOCK_MAIN_NEWS.tpl for the main_news block) that controls its HTML structure. You can modify this template to change the layout and styling of the block's output.

An easy way to do this is through the template editor in Admin Zone > Style > Themes, and click edit templates for the relevant theme.

Question How can I ensure my website complies with email marketing laws?
Answer Email marketing laws like CAN-SPAM protect recipients' rights to unsubscribe. Your website must include a clear 'List-Unsubscribe' header in every email, offer an easy unsubscribe process, and respect unsubscribe requests promptly. Composr provides built-in mechanisms, including an unsubscribe endpoint and support for the List-Unsubscribe header, to facilitate compliance.
Question What are my responsibilities regarding user privacy?
Answer You must have a comprehensive privacy policy that details the personal data you collect, its usage, and if it's shared with third parties. Laws like GDPR have strict requirements, including logging data access, data purging, and security measures. California law mandates specific elements in your policy, like handling "Do Not Track" requests and a clear process for communicating changes.

Composr has an automatic Privacy Policy generator block to help you get started. This is used by default.
Question How can I create effective website rules?
Answer A well-defined rules page is crucial for setting expectations for user behavior and outlining consequences for violations. It should cover a range of offenses with appropriate punishments, reference relevant laws, and assign legal responsibility to users. Composr provides default rules pages that can be customized, and this page is displayed to users upon joining the site.
Question What are the key legal considerations for running a website?
Answer Several legal aspects need careful attention when operating a website, especially for large or corporate sites. These include establishing clear rules and terms of service, adhering to privacy laws like GDPR and California's regulations, managing personal data responsibly, complying with email marketing regulations like CAN-SPAM, ensuring website accessibility, addressing eCommerce regulations, and understanding liability for content and user actions.
Question How do data-tpl and data-view behaviors work in Composr's JavaScript?
Answer Composr uses data-tpl and data-view behaviors for associating HTML templates and JavaScript views, respectively. This facilitates clean separation of presentation and logic:
  • data-tpl: Used with the $cms.behaviors.initializeTemplates function and PARAMS_JSON tempcode directive to bind JavaScript logic to HTML templates.
  • data-view: Used with the $cms.behaviors.initializeViews function to associate JavaScript view classes (inheriting from $cms.View) with specific HTML elements.
Question What are the advantages of using Composr's JavaScript libraries?
Answer Composr's JavaScript libraries like $cms, $util, and $dom offer several advantages:
  • Organization: They provide a structured way to access Composr-specific functionalities, avoiding global namespace pollution.
  • Abstraction: They encapsulate common tasks, simplifying DOM manipulation, form handling, and interaction with Composr's UI.
  • Consistency: They offer a consistent API across different parts of Composr.
Question How does Composr implement the Model-View-Controller (MVC) pattern?
Answer
  • Model/API: The sources directory primarily houses scripts forming the Model/API, handling data logic and business rules.
  • View: Templates in themes/default/templates represent the View, responsible for presenting data to the user. Comcode pages can also be considered part of the View.
  • Controller: Entry scripts like index.php and site/dload.php act as front controllers, directing requests. Modules and blocks, residing in */pages/modules and sources/[mini]blocks, respectively, serve as controllers, managing user interactions and determining which View to render.
Question Can I translate my content into multiple languages?
Answer Yes, Composr supports multi-language content. You can enable this feature by:
  • Installing multiple language packs: Make sure you have at least two language packs installed.
  • Enabling the Conversr multi-language option: Go to Admin Zone > Setup > Configuration > Site options > Internationalisation.
  • Running a Commandr command: Execute the necessary command to set up the database structure for multi-language content (unless you already enabled Support content translations when installing).
Once enabled, you can translate your content into different languages and allow visitors to choose their preferred language.
Question My language uses gendered descriptors. How can I handle this in Composr?
Answer Composr offers solutions for languages with gendered descriptors:
  • Template editing: You can modify templates to use different language strings based on user gender. This involves adding Tempcode logic to dynamically select the appropriate string.
  • Custom Profile Fields: Create a Custom Profile Field for "Gender" and use it to conditionally display gendered language strings in templates.
These methods allow for flexible handling of gendered language variations.
Question What are language strings, and how are they used?
Answer Language strings are phrases or pieces of text used throughout Composr. They're identified by unique codenames, like WELCOME_MESSAGE. These strings are stored in .ini language files and used to display text in the user interface.

By translating language strings, you change the text displayed on your website without modifying the underlying code.
