Has anyone else using phpESP experienced problems with php4.0.6 when
running phpESP (I'm sure this is a php4.0.6 problem, but hoping for a
workaround rather than having to take php4.0.6 off of my production
system).

Periodically when using phpESP (both the administrative interface as well
as when "responding" to a survey), the httpd daemon processing the request
will SIGSEGV.

I'd like to go ahead and upgrade to php4.1.1, but I only want to do that

Also it would still be nice to retain some sort of
compatability for browsers without javascript (or with
javascript turned off). I guess this is less of an issue
these days. Maybe it's just me who keeps it turned off to
keep from seeing X10 pop-under ads.

Re: [phpesp-general] Javascript insertions

[Sean M A. <sea...@gr...>]

The slick way to go about this of course would be to make php generate
the javascript dynamically from the choices that the admin makes for a
particular set of questions.

Keep in mind though that this could screw with the results, making them
less understandable.  If you have question 1 which is a yes/no answer,
and then have question 2 who's answers (and/or question) depend on the
answer to question 1, you create a branching of the results....

Question 1
Yes	50%
  - Question 2
      A)	10%
      B)	35%
      C)	40%
      D)	15%
No	50%
  - Question 2
      E)	5%
      F)	70%
      G)	25%

Would you present it this way?  Would you tally the total respondents
for question 2 as being the sum of the respondents for each branch of
question 2 (as I've depicted) or would it the percentages need to be
skewed such that Question 2 adds up to 100% regardless of which branch
an answer was made?


It certainly presents a challenge.  I work with a commercial knowledge
management system that uses an HTML output preprocessor, which they call
WebLingo.  It really works just like php the way it's embedded into an
HTML structure or vice versa.  Anyway, they use it to dynamically create
what could be several different javascript programs within the same HTML
file depending on how it's accessed, what's in the user's cookie, or
something along that line.

[phpesp-general] Javascript insertions

[Paul B. <pbo...@sc...>]

Hi,

I discovered phpESP a few minutes ago: seems a great program!
I have two questions, however:

1) I would like to include pictures with questions.
It appears that this is possible by including <img src=.... in the question 
text. Is this intended (to include any HTML)?

2) A difficult one: sometimes there are surveys where an answer on one 
question may impose a change in the possibilities for another answer.
This is in theory possible to implement with client-side javascript. Is 
there a way to do so? I could live with some extra textfields in the admin 
interface where the javascript code is entered. Or a pointer in the code to 
add such functionality?

Thanks

Re: [phpesp-general] BUGFIX: view results from handler

[James E. F. <jf...@ac...>]

Oh! I didn't think of that. I intended for it to be a
separate page of results. I suppose if you want the results
and the survey on the same page you could do that. I
haven't tested it that way, but apparently it works. =)

Hi,

I think phpesp is such an interesting tool and I wish to use it.
Before that, I have got some questions to ask.

- Is it possible to using another database than SQL (directly to avoid a
transfer)
- What version is the more recent and where is it availaible ?
- Is there a good forum dedicated to that tool ?

I thank you in advance.

Hi James,

when i change this line, i will see only the Results, cause inside of
that if  is a return; so it never goes through the part where the survey
is build. By removing this return; (line 34 in handler.php) it works for
me. First the results are displayed and then the survey. I think that is
how it should look like, or?

[phpesp-general] ANNOUNCEMENT: phpESP v1.3 (final) released

[James E. F. <jf...@ac...>]

This is the final release of v1.3. This is the most current
stable release of phpESP. NOTE: The database layout of this
release is NOT compatible releases before 1.3-RC1.

Download:
 http://prdownloads.sourceforge.net/phpesp/phpESP-1.3.tar.gz

If you are using version 1.3 RC1 or RC2, you can just
replace the existing files with these (and edit
paths/config if neccessary). If you are using a version
previous to v1.3 RC1, I suggest installing this in a
separate location, with a new database.

Please see the SourceForge site for more information.

Wow. Surprisingly enough this issue has come up before.
No definitive solution was reached.

The way the surveys are stored in the database does not
make multiple languages of the same survey to be stored.
One kludge that will work without modification is as
follows:
 1) *Fully* create a survey in one language.
 2) Copy the survey for each additional language.
 3) Change the text *only* (no order changes, option
    changes etc)
 4) Enable all surveys and direct users to the appropriate
    one (based on language).
 5) Use the "Merge Survey Results" (hidden) feature.
    [ manage.php?where=merge ]
The Merge feature assumes that the surveys are *identical*
in layout, so Q1 on S1 corresponds exactly to Q1 on S2 etc.

The above solution was an interim solution. The best real
solution I could come up with was to move the survey
backend format to XML (rather than SQL tables). By using
XML many problems are solved:
 o Much more flexible format (e.g. text in misc places)
 o Easy to use different front ends other than HTML (via
   XSL)
 o Customizable report/results pages (also XML)
But there are still problems. I have not found a definitive
way on how one should include multiple languages in one XML
file. There are "lang" attributes that can be used ... And
of course you could use more than one XML file (one per
language).

I have done work on using XML with phpESP, but am stalled
on releasing it because of this problem. I don't want to do
it one way then having to do it over another way. I would
greatly appreciate any feedback from anyone with experience
with multi-lingual apps.

I would welcome any patches you send me for this. At the
moment I don't have time to do this. I have added it to the
list of feature requests on sourceforge.

They should be save to the DB. The responses should
accumulate in test mode each time you fill it out (just
like a normal production survey). Can you provide me with
more details (off the mailing list), or duplicate the
problem on the Demo site?

Email functions are probably not done. I haven't looked at
that part of the code in a long time.
  [ admin/include/lib/espresponse.inc:392 ]

Math functions are fine. People always want results in
different formats or statistical methods, but for the sake
of simplicity and general audience they will stay as they
are. Any significant analysis of results should be done in
a statistical analysis program.

[phpesp-general] BUGFIX: view results from handler

[James E. F. <jf...@ac...>]

Hey everyone,
  Another bug squashed. If you tried to display results to
the public by using handler.php, it would fail to do so and
show the survey. I had 'defined' instead of 'isset' on line
31 of public/handler.php. Either get the latest version
from CVS or change the line by hand if you need this
feature. (Thanks to Ken Teague for the bug report.)

For those of you who didn't know about this feature I will
explain. The handler is capable of embedding both the
survey itself and the results in a template. To embed the
results simply add the statement ``$results=1;'' to the PHP
tag in your template. For example:
  <?php $sid=42; $results=1; include('.../handler.php'); ?>

Take it easy,

[phpesp-general] Multilingual support in surveys

[Danie R. <dr...@tu...>]

I can translate the interface, which is cool and 50% done. I want to be
able to translate the surveys as well. Let me explain:

Here in South Africa we have 11 official languages. Yes eleven. The
university is a Afrikaans/English university. I need then to let the
students select the language and do the survey. But the results has to
be stored the same way regardless of what language the survey was taken
in.

Where do I start?

Re: [phpesp-general] Should or can I use the CVS version?

The code in the CVS tree is the most recent code. At times
this may be very unstable. At the moment the code in CVS is
stable, and is preferred to 1.3 RC2 because of a few bugs
that I have fixed. The main reason CVS is stable now is
that I am preparing to release 1.3, so I am only committing
bug fixes, not new code. However, my first consideration
when I say "stable" is data integrity; in other words data
collected from surveys is correct and will not be
corrupted. In this respect 1.3 RC2 is just as stable as the
code in CVS, however when viewing the results (in phpESP)
the CVS code works better because of bug fixes.

So to sum this up. If you are running 1.3 RC2 you are fine,
you will be able to easily upgrade to 1.3 (final) when I
release it and you do not have to worry about any data
loss. While using 1.3 RC2 you *do* have to worry if you
rely only on phpESP for data analysis.

I would suggest that if you have the ability, you should
use CVS. CVS is a wonderful tool, and will make upgrading
and fixing bugs much easier. For example, if you have 1.3
RC2 from the CVS tree, and I release 1.3 (final) all you
have to do to upgrade is type:

[phpesp-general] Should or can I use the CVS version?

[Danie R. <dr...@tu...>]

Is CVS more stable than RC2? Should I use CVS rather than RC2?

Zero (0) values are ok. Are you still getting incorrect
results? Make sure you have v1.4 of lib/esphtml.results.inc.
The files in the CVS tree are more recent than 1.3RC2.

Thanks for the N/A explaination.
The Code i use is the latest (1.3 RC2) and the code  in your CVS
repository is generating the 0 values for the ranking. Version 1.5 of
the  survey_render.inc file.

Thanks again for the nice tool ;-)

There was a bug in that. Try using the latest code from the
CVS tree (http://sourceforge.net/cvs/?group_id=8956).

Yeah, the precision option enables or disables the use of
the "N/A" field (not applicable). If a respondant checks
"N/A" then they are not counted in the "TOTAL" for that
option. For example, the first respondant picks "3" for a
question, and the second picks "2". The results now show
"2.5" as the average (3+2)/2. Then the third picks "N/A",
the result is *still* "2.5" because even though there are
three responses, only the first two are considered because
the third said that the question was not applicable (for
whatever reason). However, as you have seen, the database
keeps track of the number of "N/A" responses ... How would
you suggest handling this data when showing the results.

Well, you should be able to do this without changing any
code. Its a little messy right now, because I adopted the
authentication code from something I wrote using an
external authentication method. The way to do it is just to
add the user in for each group, with the same password.

If you have so many students, I assume you will be adding
accounts with a script (not by hand in the web interface).
So something like this should work:
  INSERT INTO respondent (username, password, realm, fname, lname)
  VALUES ('foo', PASSWORD('foopass'), 'subj1', 'John', 'Doe');
  INSERT INTO respondent (username, password, realm, fname, lname)
  VALUES ('foo', PASSWORD('foopass'), 'subj2', 'John', 'Doe');

Hope that helps.

[phpesp-general] Where do I start looking?

[Danie R. <dr...@tu...>]

Great program Jimmerman! It's really well thought out.

Where do I start looking if I want to change it to do the following:

I want students (respondents) to be able to fill in only certain
surveys. But the students is part of more than one subject (group). 

So I guess I want it so that I can assign more than one group to a
student.

It's about 20000+ students and I have no idea how many subjects.

Once again thank you for the great work!
