DEPRECATION WARNING

This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

Introduction¶

In TypoScript templates there exists a function called getText, which makes it possible to retrieve values from a great number of sources (GET/POST, TSFE, rootline, etc.). This extension provides a library which aims to reproduce this capability, so that it can be used by developers in their own extension.

This can be useful in cases where you have some kind of configuration but are not using TypoScript, for whatever reason.

So what is an expression?¶

Like for the TypoScript function, an expression – at a minimum – is comprised of a key, a colon (:) and a value. Example:

gp:no_cache

The above syntax will instruct the parser to look for a GET/POST variable called "no_cache". The key represents the "space" where to look for the value. With some special keys, the value takes a different meaning. This is documented below.

The parser library can either parse a single expression or parse expressions inside strings, provided expressions are placed between curly braces. Example:

This is the value of no_cache: {gp:no_cache}

Questions?¶

If you have any questions about this extension, please ask them in the TYPO3 English mailing list (typo3.english), so that others can benefit from the answers.

Keeping the developer happy¶

If you like this extension, use the social functions of the TER to make some buzz about it. Alternatively, if you want to give something back, you may consider my Amazon wish list: http://www.amazon.co.uk/registry/wishlist/G7DI2AN99Y4F

You may also take a step back and reflect about the beauty of sharing. Think about how much you are benefiting and how much yourself is giving back to the community.
