Validate answer in function of a previous answer was created by limes4LN
Hi,

I have Question 1 with 3 answers. Then, Question 2 where I want the user enter the lengh of his speech in this format M:SS (minutes:seconds).

1) What field I should use for Q2 ?
2) Do you have an example to valid the patten M:SS (I saw some example on the wiki, but regexp are not my friend)
3) if Answer from Q1 (A1) = foo, then, A2 must be less then 1:30, if A1 = bar, A2 must be less then 2:30, is it possible ?

Thanks

1) Short-text question type.

2) Some bigger brains than me may have more elegant expressions but this regex should work for less than 1:30:
Code:
/^(1:[0-2][0-9]|0:[0-5][0-9])$/
And this should work for less than 2:30:
Code:
/^(2:[0-2][0-9]|[0-1]:[0-5][0-9])$/

3) You can use the regexes in the "Question validation equation" with an IF statement. Something like this:
Code:
if(q1 == 'foo', regexMatch('/^(1:[0-2][0-9]|0:[0-5][0-9])$/', q1Regex), regexMatch('/^(2:[0-2][0-9]|[0-1]:[0-5][0-9])$/', q1Regex))
And perhaps a "Question validation tip" like this:
Code:
Must match format and be less than {if(q1 == 'foo', '1', '2')}:30


.

Maybe this will help...

Sample survey:

File Attachment:

File Name: limesurvey...6895.lss
File Size:14 KB


With this logic in q2:

Hello

I'm back and I have troubles to implement what I need exactly. My exemple was a tiny bit simpler then what I want to do

What my question validation equation should look :

if(
Q00021 == '1', regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032),
Q00023 == '1', regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032),
Q00024 == '1', regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032),
regexMatch('/^(1:00)$/', Q00032)
)

but it doesn't work.
I would like to do something like this :

if ( Q00021 == '1' OR Q00023 == '1' OR Q00024 == '1'); then
regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032
elif ( Q00022 == '2' OR Q00025 == '3' OR Q00026 == '2'); then
regexMatch('/^(2:[0-2][0-9]|3:[3][0])$/', Q00032
else
regexMatch('/^(0:[0-2][0-9])$/', Q00032
fi


How can I do that ?

Have a look at Expression manager nested IF statements - www.limesurvey.org/manual/Expression_Manager#Equations_2

I think this is what you need (line breaks added for clarity):
Code:
if(Q00021 == '1' OR Q00023 == '1' OR Q00024 == '1', 
  regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032), 
  if(Q00022 == '2' OR Q00025 == '3' OR Q00026 == '2', 
    regexMatch('/^(2:[0-2][0-9]|3:[3][0])$/', Q00032), 
    regexMatch('/^(0:[0-2][0-9])$/', Q00032)
  )
)

Tpartner, with your help, I did a big job, here it is :
Code:
if(Q00021 == '1' OR Q00023 == '1' OR Q00024 == '1', regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032),
  if(Q00021 == '3' OR Q00022 == '1' OR Q00023 == '3' OR Q00023 == '3' OR Q00023 == '5' OR Q00023 == '6' OR Q00024 == '2'  OR Q00025 == '1', regexMatch('/^(1:[3-5][0-9]|2:[0][0])$/', Q00032), 
    if(Q00021 == '4' OR Q00021 == '7' OR Q00021 == '9' OR Q00024 == '3' OR Q00024 == '4' OR Q00024 == '5', regexMatch('/^(1:[3-5][0-9]|2:[0-2][0-9]|2:[3][0])$/', Q00032), 
      if(Q00022 == '3' OR Q00022 == '4' OR Q00022 == '7' OR Q00025 == '2' OR Q00025 == '3' OR Q00025 == '4', regexMatch('/^(1:[3-5][0-9]|2:[0-5][0-9]|3:[0][0])$/', Q00032), 
    regexMatch('/^([0-9]:[0-5][0-9])$/', Q00032)
      )
    )
  )
)


But it doesn't work !
It only works if I do this for example
Code:
if(Q00021 == '1', regexMatch('/^(1:[0-2][0-9]|1:[3][0])$/', Q00032), regexMatch('/^([0-9]:[0-5][0-9])$/', Q00032)

I think I found a problem : Q00021, Q00022, Q00023 are not displayed at the same time, only one of them are displayed according to previous answers, the rest of them are hidden. Looks like this If statement is bogus when one of the question is the condition is hidden, it that possible?
