RegEx Examples for Custom Fields

For 2 of my custom fields, I'm using Regular Expression to make sure they are formatted correctly, and that members can't take the piss with them (BHP and Torque)

For this, I'm limiting them to < 999.99 bhp and lb/ft and they can enter upto 2 decimal places, or whole number

This is the regex I'm using:

Code:

^\d{2,3}\.?\d{0,2}?$

^ - start of anchor
\d - Numbers
{2,3} - between 2 and 3 numbers in length
\.? - escaped the decimal place, and set it as optional with ?
\d{0,2}? - 2 numbers after decimal place and also set optional with ?
$ - end of string anchor

 

Oh it most certainly is!

 

and another one to correctly format the year (YYYY)

Code:

[1-2][0-9][0-9][0-9]

I only want them to be able to enter 1 or 2 for the first character. I could build it out and make it more specific, but hopefully my members aren't going to be that retarted

 

Bit more customisation



This is using the Value Display HTML to apply the extra formatting on the end of the value the member enters.

Nice and easy:

Code:

{$value} bhp
