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.
Monetary payments: Issue refunds through your payment gateway.
Point payments: Manually refund points through the points system.
Cancellations: Cancel purchases in the Admin Zone to allow repurchasing. Remember to manually undo any associated actions (e.g., removing name highlighting).
Composr supports PayPal, CCBill, and Authorize.Net for processing payments. While Composr could be extended to support other gateways, doing so may require professional development and customization.
Yes, the unified Composr search system allows users to find downloads based on keywords. This includes searching within download titles and descriptions, as well as within the content of certain file types like PDFs, text files, and even some binary formats (providing they are not too large in size).
Yes, Composr automatically creates a gallery for each download (if the galleries addon is enabled). You can easily add images directly after creating the download or through the download-view screen. The download gallery is displayed within the download-view screen itself.
Are there security features to protect downloaded files?
Answer
Yes, Composr includes security measures to protect downloads.
Protection from hackers: Uploaded files are stored with obscured filenames, preventing direct access and bypassing of the download system. Additionally, an anti-leech feature (when enabled) prevents direct download links from being shared on other websites (this is done by requiring a session ID which is validated against the person / device accessing it and only provided when Composr presents the download links to you on the site).
Basic security: Composr will not let anyone upload dangerous scripts (such as PHP files) which can be executed.
Rootkit detection: The rootkit detection tool under yourbaseurl/rootkit_detection.php can help scan files for shell scripts and backdoors. Composr's Health Check can also do this regularly. Note this only offers very basic detection and will not work for obfuscated backdoors (you should use antivirus to scan for those).
It is the responsibility of webmasters to run antivirus on their site to regularly scan files uploaded to it. Composr does not include antivirus software or virus scanning.
