Question | What is a "page-link," and how does it differ from a URL? |
---|---|
Answer | A page-link is a Composr-specific way to reference a page or screen within your website. It's a simplified, local representation of a URL, independent of the URL scheme you might be using. For example, the page-link site:downloads:browse:10 points to the download category with ID 10 in the site zone. This page-link remains consistent even if your URL scheme changes the way URLs are structured. Page-links also do not consider monikers, so if a URL moniker changes, page-links will stay the same. This is a powerful feature as you can use the Comcode [page="page-link"]Page title[/page] tag to generate URLs of local content. And these will always work regardless of URL scheme or moniker. |
Question | How do menus work in Composr, and can I customize them? |
---|---|
Answer | Composr has a flexible menu system that can be customized to your needs.
Menus can be added to panels (sidebars, headers, footers) or embedded directly within Comcode pages. The menu editor provides tools for adding branches, setting captions, tooltips, and URLs, and even defining context-sensitive behavior using "match-keys." |
Question | What are "zones" in Composr, and what are they used for? |
---|---|
Answer | Zones are like sub-sites within your Composr website. They provide a way to organize content and apply different settings, like permissions, themes, and navigation. Some default zones include:
|
Question | What are the different ways to control access in Composr? |
---|---|
Answer | Composr offers a robust permission system with various methods for controlling access:
|
Question | What happens when I add a new usergroup to a third-party forum integrated with Composr? |
---|---|
Answer | If you are not using Conversr as your forum, Composr won't automatically assign any permissions to the new usergroup. To rectify this, you can use the "Absorb usergroup-permissions" feature in the Admin Zone. This tool allows you to copy the permissions from an existing usergroup to the newly created one, ensuring consistent access and functionality. |
Question | What are some security considerations regarding super-moderators and super-administrators? |
---|---|
Answer | While super-moderators have extensive access to manage your site, certain sensitive privileges are reserved for super-administrators. This includes the ability to impersonate other users, execute arbitrary code, and view private content. These restrictions help prevent potential privilege escalation and ensure the overall security of your website. Exercise caution when granting super-moderator status and trust only reliable individuals. |
Question | What are some useful tools for debugging permission issues? |
---|---|
Answer | Composr provides a couple of tools to help pinpoint permission problems:
|
Question | How can I test if my permission settings are working correctly? |
---|---|
Answer | Composr's "SU" feature allows administrators to temporarily assume the identity of another user, enabling you to experience the site as they would. Simply enter the desired username in the "SU" box in the footer. You can also use "Guest" to browse as an unauthenticated visitor. Remember that using "SU" doesn't accurately reflect online status and retains administrator access to sensitive areas. |
Question | Can I display different content to different usergroups? |
---|---|
Answer | Yes, you can achieve this by leveraging Tempcode within your templates. By using conditional statements like {$IS_IN_GROUP} and {$HAS_PRIVILEGE}, you can show or hide specific content sections based on the user's group membership or privileges. This technique allows you to "tease" premium content to non-paying users or tailor the user experience based on their access level. |
Question | What are match-key permissions and why would I use them? |
---|---|
Answer | Match-key permissions provide a more granular level of access control beyond the standard zone, page, and category permissions. They allow you to restrict access based on specific "match-keys", which are unique identifiers for different actions or content within Composr. For instance, you could use match-key permissions to prevent guests from submitting banners or to restrict access to the member directory for all but specific usergroups. You can also specify custom access denied errors for each match-key. A "match-key" is typically a page-link, such as cms:cms_banners:add. |

Question | Should I use the bleeding edge releases or the git repository? | ||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Answer | That depends on several factors. Here are some pros and cons of each:
Click here to access the git repository. |
Question | Can I switch a v11 install from git over to using the releases from composr.app? |
---|---|
Answer | It is not recommended you do this because you may run into issues. For example, some changes were made in crypto_master.php and data/upgrader2.php prior to the first v11 alpha. These changes will result in a broken upgrade unless you already pulled these changes from git. Similar situations could happen in the future as well. It is recommended you either discard the git install and use a fresh install from the Downloads, or to maintain a git install and a bleeding-edge release install separately. Do not combine the two. |
Question | Should I update my non-bundled addons after updating to a newer release of version 11? |
---|---|
Answer | Absolutely! Frequent changes may be made to both bundled and non-bundled addons. Bundled addons will be updated via the upgrader. For non-bundled addons, you will have to update them through the addons management screen (Admin Zone > Structure > Addons). You will be informed which ones need updated. Once version 11 reaches release candidate, we do not expect frequent updates to non-bundled addons anymore. But it is still good practice to check after every update. |
Question | Can I upgrade a version 10 site to version 11? |
---|---|
Answer | Yes, for basic non-custom v10 sites. However, expect some issues to arise in the process. And please report those issues to the tracker. For v10 sites with non-bundled addons or customisations, upgrading to v11 will likely break the site until you update the non-bundled addons or temporarily remove the customisations. We aim to have the upgrader fully functional for a large majority of types of sites and for sites using non-bundled addons by the time version 11 reaches release candidate stage. We do not recommend upgrading production v10 sites at this time until v11 reaches stable. |
