Language extension

[eluser]XMadMax[/eluser]
I have made some improvements to the language helper, to allow multiple substitutions.

Yo can have this on your english (dolar) language file:

$lang['price'] = '$ %6.0d';
$lang['is_lower_than'] = '%s is lower than %s';
$lang['must_to_be_as'] = '%s must to be as %s';

Yo can have this on your spanish (euro) language file:

$lang['price'] = '%6.2f €';
$lang['is_lower_than'] = '%s es más pequeño que %s';
$lang['must_to_be_as'] = '%s debe ser como %s';

To call slang function, you must to load your language file, load the language helper and call the slang function as:

$this->lang->load('pagination','english'); // Can be declared in your controller
$this->load->helper('language'); // Can be declared in any template

// inside your template
echo slang("price",$data["price"]);
echo slang("is_lower_than",array('1','2'));
echo slang("is_lower_than",array($data["val1"],$data["val2"]));

I have put a language_helper.php in my application/helper directory. The lang function still in the code to allow normal use of it, and added a new slang function.

Here the language_helper.php code:

Revision.

Forgot to include improvements to slang function when ID parameter present.

Perfect! Thank you so much! :-D

Works nicely with CI 2.0.
