Question	How can I customize Composr without modifying the core files?
Answer	Composr offers a robust override system. Instead of altering the original files, create a parallel structure within _custom directories. For example, to modify site/pages/modules/polls.php, place your customized version in site/pages/modules_custom/polls.php. The tutorials outline additional information on how to utilise overrides.

Question	What are the main components of the Composr framework?
Answer	Composr consists of: Modules: PHP files that provide related screens, forming the building blocks of addons. Comcode: Text files containing content written in a simplified markup language. HTML: Files containing standard HTML for web pages. Sources: PHP code files for the core API and functionality. Hooks: PHP files enabling addons to interact and extend each other's functionality. Blocks/Miniblocks: Reusable components for displaying dynamic content within pages. Themes: Folders containing images, CSS, and templates to define the look and feel. Language files: Files holding text strings for multilingual support.

Question	How can I embed third-party widgets into my Composr pages?
Answer	Composr supports embedding widgets from various websites, like Google Maps, Vimeo, and YouTube, by simply pasting the URL. For manually embedding widget code, you can paste it into the HTML source view of the WYSIWYG editor or within Comcode html tags if not using the WYSIWYG editor.

Question	What is the difference between blocks and boxes in Composr?
Answer	Boxes are visual elements that provide a container for content, while blocks are functional units that generate and display dynamic content. Although blocks often appear within boxes in the default templates, they are not inherently tied to any visual representation.

Question	Can I customize the appearance of blocks?
Answer	Yes, you can style blocks by editing the associated templates and CSS. Templates are typically named after the block they represent. For example, the main_news block uses the BLOCK_MAIN_NEWS.tpl template.

Question	How do I create custom filter forms for my content?
Answer	The main_content_filtering block can help you generate filter forms automatically. You can use it to create a default form and then customize the generated Filtercode string to refine the filtering options. Once satisfied, you can either continue using the block or extract the HTML and modify it further.

Question	Where can I use Filtercode and Selectcode in Composr?
Answer	Filtercode is supported in various blocks, such as main_multi_content, main_gallery_embed, and main_cc_embed. It's also actively used in modules like catalogues, downloads, galleries, members, and news. Selectcode is supported in blocks and Comcode tags that explicitly mention it, including the main_multi_content block and the if_in_group Comcode tag.

Question	What is the difference between Filtercode and Selectcode?
Answer	Filtercode is used for querying content based on properties and values, while Selectcode is used for directly specifying a list of IDs or categories to include or exclude. Filtercode offers more complex filtering options, while Selectcode is more straightforward for simple selections.

Question	How can I filter content in Composr?
Answer	Composr provides two filtering systems: Filtercode and Selectcode. Filtercode is used for selecting content based on defined filters, such as field values, ratings, or keywords. It utilizes a syntax of comparisons, separated by commas, where each comparison specifies a field and a matching condition. Selectcode is a simpler syntax for specifying a list of IDs or categories to include or exclude from the results. It uses a comma-separated list of match-specifier tokens, such as individual IDs, ranges, or wildcard characters.

Question	What are blocks in Composr and how can I use them?
Answer	Blocks are dynamic elements that can be inserted into Comcode pages to add interactive and data-bound functionality to your website. They are essentially reusable components that automatically generate content, such as recent forum posts or information about the logged-in user. You can add blocks to your pages using the block construction assistant, which allows you to select from a list of available blocks, set their parameters, preview them, and generate the necessary Comcode.

Question	What is the purpose of "confirmed" and "non-confirmed" sessions?
Answer	Composr distinguishes between confirmed and non-confirmed sessions for added security: Confirmed: When you actively log in with your credentials. Non-confirmed: When you return to the site and are automatically logged in via cookies. You can configure zones to require confirmed sessions, preventing access from cookie-based logins alone. The Admin Zone uses this by default.

Question	How can I enhance the security of my Composr installation on shared hosting?
Answer	Shared hosting environments can be inherently less secure. Here are some tips: Choose a Secure Host: Opt for hosts that offer suEXEC and open_basedir for better account isolation. Test Security: Verify the host's security measures with the provided filesystem_browser.php script. Restrict _config.php: Remove world-writable permissions from _config.php after installation.

Question	How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer	Composr utilizes multiple layers of defense against XSS attacks: HTML Filtering: Configurable levels of filtering prevent malicious script injection. Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded. Input Sanitization: Data is sanitized before being processed to prevent malicious code execution. Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.

Question	What are the different types of security alerts in Composr?
Answer	Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include: DODGY_GET_HACK: Suspicious URLs with potentially harmful characters. EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions. SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious. DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files. BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts. SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction. You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).

Question	What are some tips for secure website maintenance?
Answer	Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer. Secure Email: Enable SSL for IMAP and POP3 email protocols. Strong Passwords: Use unique and complex passwords for different services. Secure Computers: Keep your own devices patched and secure. Maintenance Password: Remove the maintenance password from _config.php when not in use.

Question	What are the main security features of Composr?
Answer	Composr has a robust set of security features to protect your website, including: Passwords: Visual representation of password quality and enforcement of complexity rules. Password expiry and prevention of re-use. Secure password hashing, even if the database is compromised. Temporary passwords for staff setup. Login Restrictions: Two-factor authentication via IP address approval. IP address banning, including wildcard banning. Session locking to IP addresses. Configurable session expiry times. Ability to prevent privileged actions from auto-logged in sessions. Optional member approval process. Auditing Systems: Comprehensive audit logging of administrative actions. Logging of user actions and IP address history. Tools to analyze audit logs. Failed login logging. Hack attack detection, logging, and banning. Email notifications for changes to user credentials. Framework Security: Protection against CSRF attacks. Click-jacking prevention via CSP implementation. Secure coding standards and scanning techniques. Configurable HTML filtering to prevent XSS attacks. Secure code modularization standards. Other features: Granular privileges and access permissions. Content submission validation process. Rootkit detection system. Spam prevention systems. Web application firewall rules. Moderation systems.

Question	Why are my searches slow, and how can I improve search speed?
Answer	Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions: MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed. Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet. Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.

Question	How does the search engine handle different languages?
Answer	Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.

Question	What are quoted phrases and how do they work?
Answer	Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.

Question	How do stop words affect search results?
Answer	Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.
