The 404 handler shows custom content for missing pages but not resources like CSS or JS. The 403 handler redirects to a login URL on unauthorized access. 13.4(1y ago)518.9k↓64.3%4[3 issues](https://github.com/plan2net/sierrha/issues)GPL-2.0-or-laterPHPPHP >=8.2 Since Feb 19Pushed 1y ago4 watchersCompare [ Source](https://github.com/plan2net/sierrha)[ Packagist](https://packagist.org/packages/plan2net/sierrha)[ RSS](/packages/plan2net-sierrha/feed)WikiDiscussions master Synced 2d ago READMEChangelog (1)Dependencies (3)Versions (18)Used By (0) Ṣıẹrrḥa - Site Error Handler ============================ [](#ṣıẹrrḥa---site-error-handler) Enhanced error handlers for TYPO3's site error handling system. Features -------- [](#features) ### 404 Not Found Handler [](#404-not-found-handler) - Displays content from a configurable TYPO3 page or external URL - Falls back to standard TYPO3 error layout if content is unavailable - Optimized handling for web resources (CSS, JS, fonts, etc.) - Bandwidth-saving responses for static resources ### 403 Forbidden Handler [](#403-forbidden-handler) - Redirects unauthenticated users to a configurable login page - Optional fallback page for users with insufficient permissions - Configurable return URL parameter with marker support - Falls back to 404 handler in other cases Handlers -------- [](#handlers) ### Page Not Found (HTTP Status 404) [](#page-not-found-http-status-404) Displays content from a page or external URL. If the resource is unavailable or the content is empty, a message in the standard TYPO3 error layout is shown. When the requested URL denotes a web resource (eg a CSS file) only a small response is sent to save bandwidth ("Regular expression for resource file extensions", see [Extension Manager Configuration](#extension-manager-configuration)). The file extensions to be treated by default as web resources: - css - eot, ttf, woff, woff2 - gif, ico, jpg, jpeg, png, svg, webp - js - json - xml ### Forbidden (HTTP Status 403) [](#forbidden-http-status-403) Redirects to a login URL if access to page without a session is not permitted. If the user is already logged in, but has no access because of missing group rights he will be optionally redirected to a fallback page ("Show Content from Page on Missing Permissions", see [Site Configuration](#site-configuration)). In any other case a 404 "Not found" error is triggered. TYPO3 will invoke the configured error handler. Requirements ------------ [](#requirements) - TYPO3 13 LTS, PHP 8.2+ - 404: A page/URL that contains a human-readable "page not found" message - 403: A URL that performs a login and a redirect to a supplied URL (eg. extension "felogin") - the web server must be able to reach itself under the configured domain Installation ------------ [](#installation) Install via composer ``` composer require plan2net/sierrha ``` Extension Manager Configuration ------------------------------- [](#extension-manager-configuration) *Regular Expression for Resource File Extensions*: This is the default regular expression. `css|eot|gif|ico|jpe?g|js(?:on)|png|svg|ttf|webp|woff2?|xml` *Enable Debug Mode*: In case of configuration errors a detailed error will be shown when in *debug mode* or if the HTTP request comes from an IP listed in `$GLOBALS['TYPO3_CONF_VARS']['SYS']['devIPmask']`. Otherwise, the error will be passed on to be handled by TYPO3. Site Configuration ------------------ [](#site-configuration) ### 404 "not found" [](#404-not-found) On tab "Error Handling" create a new handler. **HTTP Error Status Code:** "404" **How to handle Errors:** "PHP Class" Save the configuration. **ErrorHandler Class Target (FQCN):** `Plan2net\Sierrha\Error\StatusNotFoundHandler`**Show Content from Page on Not Found:** TYPO3 page or external URL ### 403 "forbidden" [](#403-forbidden) On tab "Error Handling" create a new handler. **HTTP Error Status Code:** "403" **How to handle Errors:** "PHP Class" Save the configuration. **ErrorHandler Class Target (FQCN):** `Plan2net\Sierrha\Error\StatusForbiddenHandler`**Login Page:** TYPO3 page or external URL **Show Content from Page on Missing Permissions:** TYPO3 page or external URL **Return Parameter for Login Page URL:** URL query parameter of the login page without leading ? or & *Note:* The parameter for the login page used by the extension "felogin" is `return_url=###URL###`. ### URL Markers [](#url-markers) The return parameter of the URL supports marker substitution. MarkerDescription\###URL###current URL (URL encoded)\###URL\_BASE64###current URL base64 encoded (URL encoded)\###ISO\_639-1###current language as two letter ISO code (ISO 639-1)\###IETF\_BCP47###current language as IETF language tag (IETF BCP 47, RFC 5646/4646/3066/1766) aka "hreflang"Caching ------- [](#caching) Error pages are cached in TYPO3's page cache. For TYPO3 pages (not external URLs), the cache is automatically invalidated when page content changes.
