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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
