Validating Jquery Price Format Output Money

Question

I am using Jquery Price Format to format money using ,(vírgula)

to separate pennies and the .(ponto) to separate thousands, leaving something like this:

How can I validate this by only accepting numbers, dots and commas?

Obs: the prefix code R$ is not sent.

Answer 1

one of the solutions is to use a Pattern in the input field

follows an ex:

<input type="number" pattern="^[R$\-\s]*[\d\.]*?([\,]\d{0,2})?\s*$" />

this validates the following entries

1 => true
1,00 => true
R$1 => true
R$1000 => true
0,1 => true
1.000,00 => true
R$1.000.000 => true
5678 => true

and invalidates these other

1,001 => false
02,0 => false
22.42 => false
001 => false
192,168,1,2 => false
. => false
,55 => false
2000.000 => false

also you work with the mask of the field to force the use of this data.

Answer 2

In PHP you can use a regex to validate the data:

$valid = preg_match('/^(\d{1,3}\.)*?(\d{1,3}),\d{2}$/','99.999,99');

The variable $valid will store the boolean value that will inform you if the value is correct (true), or if it is not correct (false).
