The Composr repository is a user-friendly representation of Composr's data, which is typically stored in a database and on the filesystem. It presents the data in an easily accessible format using the JSON standard and can be accessed as a folder on your computer via WebDAV.
Commandr is a command-line interface designed for experienced system administrators who prefer using a command line over a GUI. It supplements the Composr Admin Zone, allowing you to execute commands in the form of:
PHP code (prefix :)
SQL database queries (prefix @) (queries must be executed one at a time; semi-colon separation is not supported)
Shell commands (prefix #)
Commandr-code scripts (store in the Composr filesystem's bin directory, and just type the name of the script)
Commandr-code commands (no prefixes)
You can access Commandr via the Admin Zone > Tools > Commandr or using the Commandr button in the footer.
Are there alternative chat solutions that integrate with Composr?
Answer
Yes, you can integrate third-party chat solutions with Composr. For example, CometChat is a commercial chat system that provides a Composr integration. You can also leverage video chat services like Talky, Jitsi, or appear.in by embedding links within your chat templates. For sales-chat needs, consider integrating a dedicated live chat platform like Comm100.
Are there any limitations to the Composr Chat system?
Answer
While the Composr Chat system provides robust chat and IM features, it does have some limitations. Currently, it does not support video chat, sales-focused chat features, desktop app integration, or optimal performance for very high volumes of concurrent users. Additionally, it is only near real-time as Composr queries for new messages using AJAX at a set interval.
Are there any safety guidelines for younger users?
Answer
It's crucial to emphasize safety, especially for younger users. Encourage them to follow these guidelines: never arrange to meet anyone from a chatroom in person, be cautious about sharing personal information, and report any suspicious behavior to moderators.
Yes, you can download logs of any chat conversation. Simply navigate to the chatroom, click on the "Download chat logs" link, specify the desired date/time range, and the system will generate a downloadable log file for you.
Composr offers a range of moderation features. Moderators can edit or delete messages, ban disruptive users, and delete entire chatrooms if necessary. Inline moderation links are available within chatrooms for quick actions, while the Admin Zone provides comprehensive moderation tools for managing chat content and user behavior.
Chatcode is a system of simple commands that you can embed within your chat messages to perform advanced actions. These actions include sending private messages to specific users within a chatroom, interacting with automated bots, sending chatroom invitations, and even creating new chatrooms.
The chat system utilizes AJAX technology, enabling dynamic updates without requiring page reloads. It includes a "Chat Lobby" where users can view available chatrooms and manage their friend lists for instant messaging. Users can join chatrooms to participate in group conversations or engage in private conversations with friends.
Composr Chat is a feature built into the Composr CMS that provides both chatrooms and instant messaging capabilities. It offers real-time, text-based communication for users on your website.
How does Composr ensure printed web pages look appropriate?
Answer
Composr uses a combination of approaches to ensure printed web pages have a suitable layout:
Automatic browser behavior: Browsers typically disable background images when printing.
CSS print stylesheets: Composr utilizes CSS to define specific display rules for printed versions of pages, such as removing margins and hiding social media links.
wide_print parameter: This parameter, activated through specific links or specifying it in the URL, further influences page layout for printing.
How can I test my website's compatibility across different browsers and devices?
Answer
Testing your website on different browsers and devices can be challenging due to operating system limitations and device availability. Here are some solutions:
Virtual Machines: Use virtual machines to run different operating systems and test various Internet Explorer versions.
Device Emulation: Use built-in device emulation features in browsers like Chrome to simulate mobile devices.
Online Testing Services: Employ commercial online testing services like BrowserStack to access a wide range of browsers and devices hosted in the cloud.
Real Devices: Conduct testing on physical mobile devices for a more realistic user experience.
What are the recommended desktop settings for viewing a Composr website?
Answer
A minimum screen resolution of 1024x768 is strongly recommended for viewing a Composr website. This is the minimum resolution for which the default theme is designed. Using a lower resolution might lead to display issues or an unsatisfactory browsing experience. As of version 11, smaller resolutions will often trigger the mobile layout automatically (responsiveness) to ensure a better UI for smaller displays.
Composr aims to support all modern browsers, including the latest versions of Chrome, Firefox, Safari, Edge, and Internet Explorer 11. It is designed to work seamlessly with browsers that automatically update, like Chrome and Firefox. For browsers with manual updates, Composr generally supports the last two releases.
While not explicitly supported, Composr will often address bug reports for other popular browsers like Opera, Chromium, and Konqueror. Additionally, Composr strives to provide an accessible experience for text-mode browsers and those designed for users with disabilities.
What is CSS and how does it impact website design?
Answer
CSS (Cascading Style Sheets) is a language used to describe the visual presentation of a web page written in HTML or XHTML. It controls aspects like:
Fonts and typography: Defining font families, sizes, weights, and styles.
Colors and backgrounds: Setting colors for text, backgrounds, borders, and other elements.
Layout and positioning: Controlling the placement and arrangement of elements on a page.
Visual effects: Adding shadows, gradients, transitions, and other visual enhancements.
By separating content structure (XHTML) from visual presentation (CSS), websites become easier to maintain and update. Changes to the design can be made without altering the underlying HTML structure.
Composr utilizes CSS extensively for theming, allowing users to manipulate the website's visual appearance.
Why is understanding XHTML important for website customization?
Answer
XHTML (Extensible HyperText Markup Language) is the language used to structure web page content. It defines the various elements of a webpage, such as headings, paragraphs, images, and links.
Understanding XHTML is crucial for website customization because it allows you to:
Modify page layout: Change the arrangement and positioning of elements on a page.
Add new content: Insert additional text, images, or other multimedia elements.
Customize the appearance of existing elements: Change fonts, colors, sizes, and other visual styles.
Integrate interactive features: Embed JavaScript code for dynamic functionality.
Composr uses XHTML for its templates, allowing users to extensively customize the website's design and layout.
What is the difference between cookies and sessions?
Answer
While both cookies and sessions are used for user identification and maintaining state, there are key differences:
Storage: Cookies are stored on the user's computer, while sessions are stored on the server.
Expiration: Session cookies expire when the browser is closed, while persistent cookies have a set expiration date. Sessions typically expire after a period of inactivity.
Data sensitivity: Sessions are generally used for more sensitive data, as the information is not stored on the user's computer and therefore less likely to be stolen by a hacker.
Composr uses both cookies and sessions. Session cookies are primarily used for user identification (such as anonymously matching a user to a session in the server database), while persistent cookies can be used for remembering login details if the user chooses.
A cookie is a small piece of data that a website stores on a user's computer. It is sent from the user's web browser to the web server each time a page is viewed. Cookies are used for various purposes, including:
User identification: Cookies can be used to identify a specific user, even if they are not logged in. This allows websites to remember user preferences, shopping cart contents, and other information.
Tracking user behavior: Cookies can be used to track user behavior on a website, such as the pages they visit and the links they click. This information can be used to improve the website's design and content.
Advertising: Cookies can be used to deliver targeted advertising to users based on their browsing history.
There are two main types of cookies:
Session cookies: These cookies are temporary and are deleted when the user closes their web browser. They are often used to store information about the user's current session, such as the items in their shopping cart.
Persistent cookies: These cookies are stored on the user's computer for a longer period. They can be used to remember user preferences, such as their login details or language settings.
