Translate your web pages easily

HOW TO CONFIGURE:

Create a txt file for each language you want to use and save it into languages folder under filename 'code for language.txt' using lowercase an the code for language thats it 'es' for spanish, 'en' for english, fr for french, and so on. Make a web search for languages codes... - You can now translate one of those languages files, for instance 'en.txt', to the rest of the languages with google translator using the function translate files. - The name of the file will be used to show the flag image related to the language - The fisrt line of the txt file define the language - The second line define the language name - Use a single line for each text to translate - You can include html tags in the file for example:

1 en
2 english
3 <span style="font-size:20px;color:red;" trans="15">This is a code expample used in this demo</span>
4 ...
5 ...

Once you done crating those languages files run the php file class_traslationfilestojs.php located in php folder. This class will process all language files included in languages folder and will create the language.js file that have to be include in your html file.

	$('.flagslist').html(flagsSelector);
	$('.flags').html(langDownLst);
    lang = (navigator.language || navigator.userLanguage).substr(0,2);
    cookies=(document.cookie).split(';');
    for(i=0;i<cookies.length;i++)
    {
       acookie=cookies[i].split("=");
       if (((acookie[0]).trim()).trim()=='lang'){
           if (acookie[1]!='undefined'){
                lang=acookie[1];
           }
       }
    }
	translate(lang);
});

	function trans(alang){
		translate(alang);
