Multi Language Tool.
This is the Language Administration page in OpenEMR (Adminstration->Language). This is where you can customize languages and language definitions. You can add new languages, ,add new English Constants, and modify/add language definitions. (Please note you can also enter your translations into the official OpenEMR Language Translation GoogleDoc spreadsheet; see section II. for details)
The following is an explanation of the options in this tool: Add Language: You get a box to enter a new language. Add Constant: You get a box to add a new string to be used in the translation function, this one should be used only if you know what you are doing, mostly, if you added some custom programming with new text output. The "constant" string can be literally what you want to say or a shorter reference to it. Edit Definitions: English is used as the reference language, if you click the English label you'll get a set of all constants and the English definitions at the side. If no definition is loaded yet for a given constant then a blank box is shown, by entering a definition and clicking "Load Definition" you save whatever changes you made. If you click other label than English, you get a set of all constants, the English definition at the side, and an input box to enter/modify the definition in the selected language.
Official OpenEMR Language Translations
The OpenEMR language translations are built from a collaborative Google Doc. If you would like to add a language or help with a current language, please contact us. You could then enter your translations into this spreadsheet, which will then become a permanent part of OpenEMR. This process has become very streamlined with a fast turnaround time, so we would suggest you enter data on this collaborative spreadsheet rather than entering into your local OpenEMR installation only. Note that the translations sets are built daily. To download the most uptodate set of translations, go HERE.
Language Translations Setting
These are configured in the openemr/interface/globals.php file. Mainly, you can configure the default language and what is displayed in the login language selection menu (you can also disable this menu). There are also more advanced setting to turn off certain parts of the translation engine. Please see the Language section of openemr/interface/globals.php for more details.
The translation is done by the xl() custom function, which can be found at openemr/library/translation.inc.php. Its semantics are very simple.
Which with examples means:
By default the function will return the translation.
First it uses the LANGUAGE constant defined to pick the translation.
Second it goes for the translation, if none is found, then the same string entered is used and returned as is.
Another example of use includes:
echo ("this and " . xl('translate this') . " that too");
Further details and rules on use can be found on the wiki here: http://www.openmedsoftware.org/wiki/Development_Policies#Internationalization
There are also wrappers to the xl() function that are used infrequently in specific situations. Please refer to openemr/library/translation.inc.php for more details.
