How can I use lang() function in helper class - El Forum - 08-30-2008

Is it posible?
I made helper for building color-picker and I need to translate it dynamicly

Of course it's possible. It's just a function. Call it when and where you need to.

It's better to use
Code:
$CI =& get_instance();
$CI->lang->line('some_line');How can I use lang() function in helper class - El Forum - 08-31-2008

Or just autoload the lang helper...

You can do that but then you have to do it for each application you want to use the helper in. I think for helper it's saver to use language library which is loaded by default.

By that same token, xwero, he can load the helper with the Loader::helper() function. The benefit is that the syntax of lang() is much cleaner.

True you have to type less but if he wants to contribute the helper then he has to put in the requirements load language helper. Which is restrictive IMO.

Not if he loads it in his helper.. I don't think you're following me.
Code:
$ci =& get_instance();
$ci->load->helper('language');
function color_picker()
{
$title = lang('cp_title');
$red = lang('cp_red');

Ok you got a point there but what if people use a version where the helper isn't present. It's a recent addition, 1.6.1 i believe. This means you have to add the language helper too with his helper. I believe you should strive to create as less dependencies as possible.
The lang() function is nothing more than a wrapper for the lang->line method.

Is it not in your fabric to not find a problem with an alternative suggestion?
If pre-language helper support is a goal of yours, fuksito, use the language class like xwero mentioned. Or, better yet, define your own language class wrapper:
Code:
function color_lang($line, $id = '')
{
$CI =& get_instance();
$line = $CI->lang->line($line);
if ($id != '')
{
$line = '<label for="'.$id.'">'.$line."</label>";
}
return $line;
}
function color_picker()
{
$title = color_lang('title');
}
