Beginnen

Als je niet een halve handleiding wilt lezen om een idee te krijgen wat je met LimeSurvey kunt doen, dan kun je ook wat van de onderstaande filmpjes bekijken.

Daarna is het lezen van de Aanmaken enquête - introductie een goed begin.

Ik wil een snelle introductie

Bekijk eerst onze basis inleiding.

Er is ook een andere inleiding die toont hoe je online enquêtes kunt maken, versturen naar een gebruiker en daarna de ingevulde gegevens kunt bekijken.

Er staan ook Engelstalige video's op YouTube:

How can I remove index.php from the URL path to get a shorter URL

If you want to use fancy URLs and so not have /index.php in every URL please edit /application/config/config.php and change 

'showScriptName' => true,

to 

'showScriptName' => false,

For this to work properly you must use an Apache webserver with a properly installed mod_rewrite module.

Hoe verwijder ik het * (rode sterretje) bij een verplichte vraag?

In LimeSurvey wordt vanaf versie 1.80 het rode sterretje bij verplichte vragen gezet in het bestand template.css ("asterisk" class). Om het te verbergen:

  • Open de sjabloon editor
  • Maak een kopie van het sjabloon dat je wilt wijzigen
  • Selecteer het bestand "template.css" en zoek naar de asterix class
  • Voeg aan het einde van de asterix class".asterisk {display: none;}" toe.
  • Bewaar template.css
  • Leeg de cache van je browser zodat het bestand opnieuw wordt geladen.

In LimeSurvey versie 1.53 wordt het rode sterretje bij een verplicht vraag gezet met de css "asterisk" class. Om het te verbergen:

  • Open de sjabloon editor
  • Kies het sjabloon dat je wilt wijzigen
  • Selecteer het bestand "startpage.pstpl"
  • Voeg de css ".asterisk {display: none;}" toe aan het css stylesheet.

Oudere versies

  • Open qanda.php in je text editor
  • Zoek naar "asterisk"
  • Zet aan het begin van de regel twee schuine streepjes "//"
  • Voorbeeld:
    • origineel: $qtitle = ''.$clang->gT('*').''.$qtitle;
    • gewijzigd: // $qtitle = ''.$clang->gT('*').''.$qtitle;

Hoe kan ik een flash bestand toevoegen?

First go to Global settings and deactivate the XSS-filter. Please also read up in the implications deactivating that filter. The following steps won't work if the filter is active.

  1. Navigate to the place in your survey where you want insert your Flash file. This can be anywhere where you can use the integrated HTML editor, for example in questions, subquestions, answers, survey welcome/end text and many more.
  2. Open the full-screen editor mode by clicking the 'LimeFitWin' button on the editor tool-bar.
  3. On the full-screen editor tool-bar you will find a little button with a Flash symbol. Click on it. A dialog will open.
  4. In this dialog you can give either the path to an existing Flash file somewhere OR you click the 'Browse server' button.
  5. If you clicked the 'Browse server' button you will be presented with a file browser and on the bottom an file upload field. Choose now an existing file or upload a file first.

Dat is alles!

Hoe kan ik deze teksten verwijderen uit mijn enquête

"There are X questions"

"A note on privacy..."

vraagcode

All these texts are inserted at the template you are using by placeholders. You can easily remove them. Go to the Template Editor and remove the {THEREAREXQUESTIONS} / {PRIVACYMESSAGE} / {QUESTION_CODE} placeholder(s).

Enquête configuratie

Hoe maak ik een openbare enquête?

To make a survey public to everyone you should:

Your survey should then be listed at the root page of your limesurvey installation. You can publish the link to the survey on your website/blog and everyone can take the survey without restrictions.

Hoe zet ik het versturen van email te bevestiging uit

If you are using tokens and a participant fills out the survey, a confirmation email is sent to his/her email address. If you don't want this message to be sent just delete the whole confirmation email subject and message. You have to switch to source code mode to be able to delete all the text. Save the empty message and no confirmation emails should be sent anymore.

Foutje gemaakt, wat nu

I forgot my admin password. How do I reset it?

  1. For version 1.47 to 1.53 only: Download this file and copy it to /<your limesurveydir>/admin/install/ .
  2. For version 1.7 or later: Restore your /<your limesurveydir>/admin/install/ directory from the download package
  3. Execute resetadminpw.php using your browser by pointing it to 
    http://www.your_domain.com/your_limesurvey_dir/admin/install/resetadminpw.php
  4. After removing the /install directory again you should be able to login with $defaultuser (Default: admin) and $defaultpass (Default: password) set in config.php.

Hoe kan ik gegevens terugzetten van gedeactiveerde enquêtes?

We recommend to always use the time-out option instead of deactivating a survey. If you closed your survey accidentally it is important that you don't change anything in the survey.

Then, and only then the following steps will work:

  1. Activate your survey again
  2. Go to the "Browse responses for this survey" menu.
  3. Click at the "Import answers from a deactivated survey table" button.
  4. Choose your source table.
  5. Click at the "Import responses" button.

Ik heb een vraag/vraaggroep/enquête verwijderd!

Dat is jammer. Als je iets verwijderd, dat is het weg. Maar je hebt vast wel regelmatig een back-up gemaakt?

Wat zijn de beperkingen van LimeSurvey

...regarding speed

There is no existing speed limit on LimeSurvey. It all depends on how fast your server and your connection is. If you expect a large number of users within a short time and you are not sure if your server can handle this check our forum for according topics about other users' experience.

...regarding survey size

Note: 'Survey size' refers to the maximmum number of questions (and answers) in your survey - don't confuse this with the number of replies on your survey (there is no limitation on that). Theoretically there would also be no limit on the maximum number of questions/answers in LimeSurvey. But the database engine you are using has several limits. The most important one is the limit on the number of fields(columns) in the result table.

  • MySQL ISAM: The sum of the lengths of the VARCHAR and CHAR columns in a table may be up to 64KB.
  • MySQL InnoDB: Maximum number of 1000 columns
  • MS SQL Server 2000: Maximum number of 1024 columns
  • Postgres: Maximum number of 250-1600 columns depending on column types. The maximum number of columns can be quadrupled by increasing the default block size to 32k. See Installation FAQ and PostgreSQL FAQ.

The mySQL ISAM engine is the most tricky one (see mysql documentation for more information). As it allows only up to 65,535 bytes per row and utf8 characters can require up to three bytes per character the maximum may be only 21,844 characters (but this depends on your DB encoding).

You can roughly calculate the size of your survey like this:

  • Every multiple numerical question: 20 chars for each answer
  • Every multiple choice & array question answers: 5 chars for each answer
  • Every other question type: 5 chars
  • Add 10% for the usual overhead

How to increase the maximum number of columns in PostgreSQL

In case your survey contains too many questions you can define a different block size in PostgreSQL so it is possible to create more columns. This might be tricky because you have to recompile PostgreSQL and set BLCKSZ to a higher value, like 16kiB or 32kiB. Watch for the configuration option "--with-blocksize=BLOCKSIZE". For details see the archives of the PostgreSQL mailing list or ask there (pgsql-patches(at)postgresql(dot)org).

Instructions for Debian (thanks to Martin Pitt): 

sudo apt-get build-dep postgresql-8.3
apt-get source postgresql-8.3
cd postgresql-8.3-*
debian/rules patch
sensible-editor build-tree/postgresql-8.3.5/src/include/pg_config_manual.h
dpkg-buildpackage -us -uc -b -nc

Survey participants get kicked out to the Surveys List page part way through. What can I do?

If you have a particularly long survey, and you find that your users can access a survey, and get part way through completing it, but then seem to get kicked out to the Surveys List page check your PHP settings. If your host is using the Suhosin extension for Apache it may be set to be too limiting on a couple of settings.

For example the two settings "suhosin.post.max_vars" and "suhosin.request.max_vars" are both set to a value of 200 by default. Increase those settings both to 400 or higher so users can complete and submit long surveys.

If you still have problems, try switching the module to simulation_mode (and so basically deactivate it), as the maximum value always depends on your particular survey.

Fatal error: Allowed memory size

Depending on your server configuration you might run into memory problems being reported by an error like "Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 233472 bytes) in /path/to/htdocs/limesurvey/filename.php on line 7296".

You can try to raise the limit by adding an optional setting to Limesurvey's config file.

Please mind that such local settings by an application can always be overruled by global server settings. To increase the memory limit to 128M directly on your server you could try adding:

  • memory_limit = 128M to your server's main php.ini file (recommended, if you have access)
  • memory_limit = 128M to a php.ini file in the LimeSurvey root
  • php_value memory_limit 32M in a .htaccess file in the LimeSurvey root
  • ini_set('memory_limit', '128M'); in your config.php
