Hello all,

So, I have searched and although there is a nice solution written by tpartner in this forum about evaluating as html:
www.limesurvey.org/forum/design-issues/9...line-break-in-string
I was wondering if there is a way to add line/paragraph/etc. breaks conditionally (I want to be able to add them only when the answer is null) and cannot find a way to do so.

I have a print page with hundreds of answers so converting them to {html_entity_decode(equation1)} method would be an endeavor.

I wanted to provide an example of the code for illustration, too:

As you can see, if it adds a pagebreak after each of those "if thens", it's bulkier than needed. This one question adds 20 blank lines if they don't fill it in during the survey on my "print" page.

Sorry to put another message here, I forgot to put the LS version: 3.21 and the attachment of the lsg (might be able to get the lss but would have to get rid of information)

Hi,
you'd always attach a lss export of the relevant questions.

Other exports (lsq and lsg) are language sensitive, meaning we have to guess which base language your group export contains, then have to create a new survey hoping the guess was right, to import your group.

AND these exports don't contain survey settings that might be important to be able to help.

Please ease our life.

Joffm

Your group only contains an equation which IMO should be a question of type "text display", but not the questions which you want to display the results of.

So again: Attach a lss export with the relevant questions. To answer your question only a small example is sufficient.

I am just going to put the whole thing here because I am lazy, but how would I truncate the .lss? just use a text editor?

Problem is, that we are lazy aswell. Human nature. And as your problem is not really our problem, our laziness prevents us from looking at your problem. If you could only find a way to provide an LSS file with just the relevant parts....


.... oh, wait, I have an idea. You could just copy the survey and in that copy you delete every question group and question that is not relevant for the problem and then export the LSS...

Now on a more serious note: This survey has 17 question groups and 94 questions in total. So it would take forever to understand the questionnaire structure and find the problematic part. You didn't even say where to find the problem within the questionnaire.

Just remember that most of us that help out in the forum here are doing this as a voluntary, we are doing this in our spare time, we are not getting paid for this. My intrinsic urge to help gets greatly reduced when it is a lot of work to even identify the problem.

Help us to help you.

I think I am going to sleep now.

I have to support holch.
To show your wishes, two or three questions were sufficient.

And it is obvious that you get empty lines. You have a "<br />" after each line, without considering if it is empty or not.
Because the linefeed is necessary only if the line is not empty, you should include the "<br />" into the "join"-function.
Like
{if(!is_empty(Q1_SQ001),join( "- ", Q1_SQ001.question, Q1_SQ001.shown,'<br />'),"")}

Because I am lazy too, I didn't change the entire code to test (that's up to you)

Joffm

And consider the remarks here in an other thread about the editor and inserting HTML code.

Dear Joffm, Holch,

I wanted to thank you both, and I am guessing you guys probably got a lot of other, terribly unhelpful responses in the forums this week. So as for saving it to a new survey and clipping the answers there.... doyyyyy did not think of that. So thanks Holch, despite the sarcasm being thick enough to cut, that suggestion will also be quite helpful. As for Joffm, thanks for walking me through what was needed, and yes, your solution did indeed solve the issue. Feels good. Next time I won't be one of the unhelpful posters.

Sidenote: Why does single ' ' work, but not " " or just having the <br /> by itself?

So thanks Holch, despite the sarcasm being thick enough to cut, that suggestion will also be quite helpful.

Yeah, I figured that it was quite sarcastic, but your "I am just going to put the whole thing here because I am lazy," was just calling for it.

Sorry if I was too tough though - it was late yesterday.

Sidenote: Why does single ' ' work, but not " " or just having the <br /> by itself?

I think single quotes and double quotes should both work, in this case, I think. Why the quotes? It indicates to the expression manager/script that it is a "string" and does not require any processing like the variables that come before it.
