Is it possible to force users to enter an answer as either an X or a two decimal number?



I had these settings to force an answer to be a two decimal number

Question validation equation: is_empty(self) OR regexMatch('/^[0-9]+(\.[0-9][0-9])$/',self)

Question validation tip: {if(is_empty(self) OR regexMatch('/^[0-9]+(\.[0-9][0-9])$/',self), "Enter number with two decimals points", "Enter number with TWO decimal points")}

Hi,
though I think this is not the best way, ... up to you.

Just extend the regular expression.
A lot of examples here:
regexlib.com/DisplayPatterns.aspx?cattabindex=2&categoryId=3

E.g.
is_empty(self) OR regexMatch('/(^[0-9]+(\.[0-9][0-9])$)|(^X$)/',self)

Why is 100.00 not considered a valid value with this?

is_empty(self) OR regexMatch('/(^[0-9]+(\.[0-9][0-9])$)|(^X$)/',self)

Could be a bug in LimeSurvey. There is a regex done in Javascript and in PHP. Somestimes there is a bug in one or both regex-routines.
You should prepare a survey with the nonworking part and attach it here.
What version of LimeSurvey was used?

Here is the survey. It's on our test environment so no worries if it's used. It's the third to the last question where I have the validation that doesn't accept 100.00

I'm on Version 2.58.0+170104

Check again.

Here is the result:
Wrong:


Correct:


regexMatch('/(^[0-9]+(\.[0-9][0-9])$)|(^X$)/',self)
As you know the "+" means: the expression before can be repeated 1 to x times and is a synonym for {1,}.
So you could try this or - I think you enter percentages up to 100 - {1,3}, which means 1 to 3 repeats.

BTW:
If you work with 2.58 there is a far better way to do this.
Use the plugin "checkboxfortext".
Here you can have one or two checkboxes below the textinput field e.g. "NA" and "DK"

That's weird that 100.00 worked for you. I had another user try and he got the same result as me. But if you put in 100.01 it would take it

No, it's because you didn't say that you use 2.58.
Of course my example was in 3.13.2

I mentioned the version up above. Is this a bug with the version I'm on?

Hi, now I tested in Version 2.73.1+171220

is_empty(self) OR regexMatch('/(^[0-9]+(\.[0-9][0-9])$)|(^X$)/',self)

Wrong entries:



Correct entries:



I have not the least idea why there are problems in version 2.58

An here is a different approach:
array with some javascript. (entries are exclusive)

Yes, you mentioned it.
But at that time I was already working on the example (not in the first post). I saw it after I submitted the post.
