Detailed Description

This is the main entry point of the TypoScript driven standard front-end.

"handle()" is called when all PSR-15 middlewares have been set up the PSR-7 ServerRequest object and the following things have been evaluated

‪correct page ID, page type (typeNum), rootline, MP etc.
‪info if is cached content already available
‪proper language
‪proper TypoScript which should be processed.

Then, this class is able to render the actual HTTP body part built via TypoScript. Here this is split into two parts:

‪Everything included in <body>, done via page.10, page.20 etc.
‪Everything around.

If the content has been built together within the cache (cache_pages), it is fetched directly, and any so-called "uncached" content is generated again.

Some further hooks allow to post-processing the content.

Then the right HTTP response headers are compiled together and sent as well.

◆ generateHtmlTag()

string TYPO3\CMS\Frontend\Http\RequestHandler::generateHtmlTag	(	array	$htmlTagAttributes,
		array	$configuration,
		ContentObjectRenderer	$cObj
	)

protected

Generates the <html> tag by evaluating TypoScript configuration, usually found via:

‪Adding extra attributes in addition to pre-generated ones (e.g. "dir") config.htmlTag.attributes.no-js = 1 config.htmlTag.attributes.empty-attribute =
Adding one full string (no stdWrap!) to the "<html $htmlTagAttributes {config.htmlTag_setParams}>" tag config.htmlTag_setParams = string|"none"

If config.htmlTag_setParams = none is set, even the pre-generated values are not added at all anymore.
‪"config.htmlTag_stdWrap" always applies over the whole compiled tag.

Parameters

array	$htmlTagAttributes	‪pre-generated attributes by doctype/direction etc. values.
array	$configuration	‪the TypoScript configuration "config." array
ContentObjectRenderer	$cObj

Returns: ‪string the full <html> tag as string

Parameters

◆ processHtmlBasedRenderingSettings()

TYPO3\CMS\Frontend\Http\RequestHandler::processHtmlBasedRenderingSettings	(	TypoScriptFrontendController	$controller,
		SiteLanguage	$siteLanguage,
		ServerRequestInterface	$request
	)

protected

At this point, the cacheable content has just been generated (thus, all content is available but hasn't been added to PageRenderer yet). The method is called after the "main" page content, since some JS may be inserted at that point that has been registered by cacheable plugins. PageRenderer is now populated with all <head> data and additional JavaScript/CSS/FooterData/HeaderData that can be cached. Once finished, the content is added to the >addBodyContent() functionality.

Parameters

TypoScriptFrontendController	$controller
SiteLanguage	$siteLanguage
ServerRequestInterface	$request

◆ resetGlobalsToCurrentRequest()

TYPO3\CMS\Frontend\Http\RequestHandler::resetGlobalsToCurrentRequest ( ServerRequestInterface $request )

protected

Sets the global GET and POST to the values, so if people access $_GET and $_POST Within hooks starting NOW (e.g. cObject), they get the "enriched" data from query params.

This needs to be run after the request object has been enriched with modified GET/POST variables.

Parameters

ServerRequestInterface $request

this safety net will be removed in TYPO3 v10.0.
