Is yii2 ignoring my configuration?
i’m have this in my web.php
'formatter' => [
'dateFormat' => 'dd/MM/yyyy',
'thousandSeparator' => '.',
'decimalSeparator' => ',',
'currencyCode' => 'ARS'
],
but when I put "20,50" in a input, still saying "…must be a valid number"
there is something missing in my config file?
Sorry for my poor English
I don’t think the validators use the formatter configuration for checking numbers etc (although they possibly should!). If you check the docs for the number validator, it has a pattern for “doubles”, which is ‘/^\s*[-+]?[0-9]\.?[0-9]+([eE][-+]?[0-9]+)?\s$/’ and which will not match the comma in European number formats. You can specify a different one in the validator configuration (and if you make it a static string, you can reuse it) and then you can set it to be whatever format you want, such as:
‘/^\s*[-+]?[0-9]\,?[0-9]+([eE][-+]?[0-9]+)?\s$/’
or more simply
‘/^[0-9]*\,?[0-9]+$/’
Which doesnt allow whitespace or the E notation.
Changing the validator so that 20,50 is allowed might work.
You could also use masked-input: http://demos.krajee.com/masked-input
But if 20,50 is stored into mysql you will get an error 
This money mask input will do the conversion "read from database -> input -> store to database":
