How to add locale into the Facebook Registration Plugin via iframe -

I am using the Facebook registration plugin through IFrame and I tried to change the language of the form using the locale parameter:

ex> & lt; Iframe src = "https://www.facebook.com/plugins/registration? Client_id = 650161075012011 and locale = 'spa_EC' and amp; redirect_uri = https% 3A% 2F% 2Fdevelopers.facebook.com% 2 floors% 2fco% {'Name': 'name'}, {'name': 'email'}, {'name': 'location'}, {'name': 'birthdays'}, {'name'}, : 'Phone', 'description': 'phone number', 'type': 'text'}] "scrolling =" auto "frameborder =" no "style =" border: none "transparency =" true "width = "100%" height = "330" & gt; & Lt; / Iframe & gt;

But that does not work, what is the correct way to always change the language of using the iframe form?

Thank you!

The locale parameter spa_EC you entered is not valid because no < Code> spa is not inside the language code.

The quotation should not be surrounded by numbers here. and Locale = 'spa_EC'

from Facebook

Set a localic parameter, which is a posix locale, which is 2 characters a _ After the 2 letter uppercase country code.

then it should be and locale = es_EC .
