Determining if a Translation Exists

Problem

You want to determine if a translation exists for a particular key.

Solution

Use the Lang::has() method.

To check if a translation exists for the current locale pass a single argument to the method. The argument is the key you’re checking.

if (Lang::has('message.welcome'))
{
    echo "The welcome message translation exists for the current locale";
}

Discussion

You can specify the locale to check with the second argument.

if (Lang::has('message.welcome', 'es'))
{
    echo "The welcome message translation exists for Spanish";
}

If the second argument isn’t used then the current locale is used.
