Deprecation: #83252 - link-tag syntax processsing

Description

The old-fashioned way of storing links as <link>-tags in the database was migrated in TYPO3 v8, however, the code is still in place.

Using the following hooks is not encouraged:

• $TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_parsehtml_proc.php']['modifyParams_LinksRte_PostProc']
• $TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_parsehtml_proc.php']['modifyParams_LinksDb_PostProc']

The following public methods in RteHtmlParser have been marked as deprecated:

• TYPO3\CMS\Core\Html\RteHtmlParser->TS_links_rte()
• TYPO3\CMS\Core\Html\RteHtmlParser->transformStyledATags()

The second argument of the PHP method TYPO3\CMS\Core\Html\RteHtmlParser->TS_AtagToAbs() has been marked as deprecated.

Impact

Transforming any content with a <link> tag will trigger deprecation warning. Additionally, calling one of the deprecated methods or triggering any of the hooks within RteHtmlParser will trigger a deprecation warning.

Using the method TS_AtagToAbs() with a second argument set will trigger a deprecation warning.

Affected Installations

Any installation which makes use of the legacy <link> syntax or hasn't fully migrated to TYPO3 v8 yet.

Migration

Migrate all content to proper anchor-tags, so the hooks are not necessary anymore.
