TYPO3 Extension link_alchemy

What does it do?

The link_alchemy extension rewrites external links in RTE text fields that refer to internal TYPO3 pages or files. These links are converted to internal TYPO3 links (t3://page..., t3://file...).

Installation and configuration

To install the extension, use Composer:

composer require plan2net/link-alchemy

No configuration is required. The extension automatically hooks into the RTE content transformation process.

Compatibility

Versions 12.0.0 and higher are compatible with the corresponding TYPO3 versions.

If you already overwrite the class RteHtmlParser in your project, you may need to adjust the XCLASS configuration in ext_localconf.php.

Usage

The extension automatically hooks into the RTE content transformation process. No additional setup is required. When RTE content is processed, external links that refer to internal pages or files will be rewritten to use TYPO3's internal link format.

Example

Here is an example of how the extension transforms a link:

• Before: <a href="https://example.com/internal-page">Link</a>
• After: <a href="t3://page?uid=123">Link</a>

This ensures that links are correctly handled within the TYPO3 CMS environment, providing better integration and consistency.

Limitations

The extension only works with RTE content transformations. It does not handle links in other contexts, such as content element input fields. You may use the already existing uri2link extension for for other fields of renderType=inputLink.
