Hi experts

Could you point what must be changed in this regex to accept two decimal places?
regex:/^[0-9]{1,2}([,.][0-9]{1,2})?$/

Open in new window


When using this it accepts correctly only digits with ","   and "."  but when saved to DB table the decimal part is truncated.

Thanks in advacne.

Hi

It is DOUBLE. But I guess comma is not acceptable in db as decimal separator... Is it configurable at MySQL?

Not sure what your code is doing that's processing the data but it could have to do with the fact that the decimal part is in a numbered capture group and the whole part is not. Try this:?

^([0-9]{1,2}(?:[,.][0-9]{1,2}))?$

This puts the entire expression into a single numbered capture group. If that doesn't work you can try putting the entire expression outside a capture group like this:

^[0-9]{1,2}(?:[,.][0-9]{1,2})?$

Is just a matter to use str_replace  changing "," by "." before to save, doing that the value is correctly saved at db table.

You have to escape it with a "\" because dot (decimal point) is reserved in Regex. It matches a single character.

Hi

The regex I used since the start is OK.
It's a matter of use the correct format  to insert values in MySQL.

Thanks.
