redaxo-addon-article2json

Adds optional JSON-Output to Redaxo-CMS-Sites which can be configured in the backend.

##Install Put all files in a separate folder and copy the whole folder to the /redaxo/addons/ directory.
After that log into your backend and activate the addon.

##Backend (add JSON-schemes) You will see a new menuitem on the sidebar which is called "REX2JSON".
If you click on it you will be able to declare a specific JSON-Output to every module that is defined in your backend.

NOTE: If there are no modules available nothing can be edited!

If there are modules available you can now press the "Schema zuweisen/ändern" button for one of these. You will see an empty textarea.
Now you can add a specific JSON-Output for the selected module, e.g.:

{
   "image": "#if#file1####file1####if#file1#",
   "title": "#if#1####1####if#1#",
   "category": "#if#6####6####if#6#",
   "date": "###2###",
   "text": "#if#3####3####if#3#",
   "link1": "#if#4####4####if#4#",
   "link2": "#if#5####5####if#5#"
}

As you can see you can define JSON-attributes for every value you need to get from Redaxo. The module-values can be retrieved by using a hashtag-syntax:

##Hashtag-Syntax

###N### => will resolve to REX_VALUE[N]
###fileN### => will resolve to REX_FILE[N]
###linkN### => will resolve to REX_LINK[N]

#if#N# ... #if#N# => will check if the value exists, otherwise if you just resolve ###N### there may be a php-error occuring
#if#fileN# ... #if#fileN# => same as above but for file-values

I know that the syntax is far from intuitive - sorry, could be done better but the plugin had to be created fast. :-)

##Frontend (get JSON-Output for articles) If you want to test your JSON-output you can open any article which contains the selected/edited modules and just add the parameter "&asjson=1" at the end of the URL.
This surely only works if you call the "index.php?article_id=X" URLs and not the SEO-optimized ones.

Please feel free to contribute and improve!
