Hi,

I am currently running a van Westendorp price analysis and switched from a slider to a free input field.

Now I have three requirements:

1. The scale should go up to 200
2. the steps should only allow values of 1 or +-0.5 - 1€, 1,5€ etc.
3. I only need one decimal number not 2.


I found this validation but don't know how to modify it:

/^[1-9][0-9]{0,2}(?:,?[0-9]{3}){0,3}(?.[0-9]{2})?$/

May anyone help me please?

Is it possible, that the follwing cases are covered?

1. 1 typed - output 1
2. 1,5 typed - output 1,5
3. 1,53 typed - error message with: "Only enter one decimal number in 0.5 steps"

Thank you very very much for your help

Ok, I think I got it

At least it seems to work fine now!

May anyone with more php knowledge double check it please?

Thank you all very much for your help

Close, but I don't think that will allow 101-199.

Try this:
This effectively says that the string must start with 100-199 OR 10-99 OR 1-9 and may be followed by .5.
