Creating stuff :)
[1/12] from: stefan:falk:slg:se at: 24-Apr-2001 22:01
Hi list,
I'm having a huge problem, I can't for my life figure out how to do this.
I have a form posting an X number of questions and answers, and I need to
know how many and create a loop. Eg. if there are two questions and answers,
I'll do this:
question1: data/question1
answer1: data/answer1
question2: data/question2
answer2: data/answer2
append block-to-save question1
append block-to-save answer1
append block-to-save question2
append block-to-save answer2
Now, the number of Q and A's is in a variable so I know the number of Q and
A's.
I would like to create a loop that would look something like this (and this
is fantasy):
for count 1 number-of-questions 1 [
question[count]: data/question[count]
answer[count]: data/answer[count]
append block-to-save question[count]
append block-to-save answer[count]
]
Now, without using my wild imagination, how is this done?

Try:
poke question count data/question/:count
I hope that helps!

Hi,
I'm not quite sure what you mean with this,
The line it should replace (if count = 1) is:
question1: data/question1

Hi,
the closest I've come to solving this is to print out everything in to a
file and "do" the file, but there has to be a better solution?

I guess I'm unclear what you're trying to do. Did you mean the
square brackets as metalanguage, or were you trying to manipulate
the contents of an array of counters?

I have some POST-data from a CGI script, with a different number of
questions and answers every time, and I want to do this with the data (if
for example there are 2 questions and answers):
--------------------------------
question1: data/question1
answer1: data/answer1
question2: data/question2
answer2: data/answer2
append file-to-save question1
append file-to-save answer1
append file-to-save question2
append file-to-save answer2
-------------------------------
However, since there are a different number of questions depending on what
the user chose,
I would like to create a loop, I know the number of questions through a
value in the data like this:
number-of-questions: 2
and then I'd like to create a loop, but replace the Q and A numbers with a
counter, that, in my wild fantasy would look like this:
for count 1 number-of-questions 1 [
question[count]: data/question[count]
answer[count]: data/answer[count]
append file-to-save question[count]
append file-to-save answer[count]
]
But of course the [count] way doesn't work, is there any way to simply
replace a char in the code for variable?

Show us an example of the POST-data,
and the corresponding output that
you would like.

Hi Stefan,
I thought I already saw the answer, but seems I just dreamt, so
here it is (translating your fantasy example to rebol, the way I
understand it ...)
Once upon a time [stefan--falk--slg--se] spoketh thus:
> for count 1 number-of-questions 1 [
> question[count]: data/question[count]
> answer[count]: data/answer[count]
> append file-to-save question[count]
> append file-to-save answer[count]
> ]
for count 1 number-of-questions 1 [
set question/:count data/question/:count ; you have to use set, question/:count: won't
work
set answer/:count data/answer/:count
append file-to-save question/:count
append file-to-save answer/:count
]
kind regards,
Ingo

Hi,
that's good except for:
** Script Error: question has no value. ** Where: set question/:count
data/question/:count
I would like to set (for the first iteration)
question1: data/question1
and I guess
set question/:count data/question/:count
isn't quite the same,
I don't want it in a block, but in a word or variable or whatever it's
called in rebol :)

I think this may answer some questions - but probably not solve your problem.
In your example you are setting two variables when I don't think that is
neccesary.
From your example it looks like your real target action is to get the
questions and
answers into the "file-to-save".
How about:
for count 1 number-of-questions 1 [
;question[count]: data/question[count]
;answer[count]: data/answer[count]
append file-to-save data/question/:count
append file-to-save data/answer/:count
]
If you are using the psuedo variables "question[count]" and "answer[count]"
somewhere
after the loop then you can just use normal variable assignments like:
last-question: data/question/:count
last-answer: data/question/:count
because that is all that those variable will be holding after the loop anyway.

That's not quite it, so here comes a quite lengthy description of what I'm
trying to do:
First, I have a form asking how many questions and answers there is (the
whole script is for adding an interview to a webpage, without having to deal
with HTML), this is then sent to a rebol script that prints the following
form (noq = number of questions):
;--------------- Only a small part of the form
for count 1 noq 1 [
print rejoin [{
<tr>
<td colspan="2">
<font face="Verdana" size="2"><b>Question } count
{</b><br></font><textarea cols="60" rows="10" name="question} count
{"></textarea><p>
</td>
</tr>
<tr>
<td colspan="2">
<font face="Verdana" size="2"><b>Answer } count
{</b><br></font><textarea cols="60" rows="10" name="answer} count
{"></textarea><p>
</td>
</tr>
}]
]
;--------------------------------
after that, this form is sent to another rebol script that will add
everything to a file:
;-------------------------------------------------------------
create-interview: func [][
noq: data/noq
date: now/date
name: data/name
nop: data/nop
short: data/short
short: replace/all short newline "<br>"
intro: data/intro
intro: replace/all intro newline "<br>"
append feature-file 'type
append feature-file type ; type: data/type was done earlier in the
script
append feature-file 'name
append feature-file name
append feature-file 'nop
append feature-file nop
append feature-file 'short
append feature-file short
append feature-file 'intro
append feature-file intro
url: data/url
homepage: data/homepage
append feature-file 'url
append feature-file url
append feature-file 'homepage
append feature-file homepage
append feature-file 'date
append feature-file date
noq: to-integer noq
for count 1 noq 1 [
questionX: data/questionX
answerX: data/answerX
append feature-file 'QuestionX
append feature-file questionX
append feature-file 'AnswerX
append feature-file answerX
]
;-------------------------
And then it goes on to save the file.
The problem is (I think) the way the form sends the data, as it sends it
with the name(s)
question1
question2
question3
etc..
answer1
answer2
answer3
etc..
This mean that even if I know the number of questions, I still have to
change the number in a line of code to get the data. (Maybe I could use some
sort of for loop to count through the data?)
After this I need a script to print the questions, which would be easy to
make if I can get this thing running. Hope this makes everything clearer!

Also, an addition that I forgot, the saved file should look something like
this:
type "Interview" name "Mama" nop "1" short "erpokgepokg" intro
pokwporkpwork
url "pokpok" homepage "pokpok" date 28-Apr-2001 question1
Blah
answer1 "Bloh" question2 "Blah" answer2 "Bloh" etc..
and it's loaded using:
interview: load %filename.r
And so it can be displayed using
print interview/name
print interview/question1
etc...
