A simple multiple-choice quiz based on plain PHP, SCSS and jQuery, including questions about Open Access in German.
Starting with a short introduction, the participant is presented with a number of multiple-choice questions. Both the order of questions and answer options are randomized for each run. After an answer has been picked, the correct one is shown along with optional additional information. When all questions have been answered, a score based on the number of correct answers and the overall time required is calculated. Results are logged to a plain text file.
A web server running PHP 5.3.6 or above.
At first, you need to have node.js with npm version 3 or above installed.
If you just want to install the quiz, run
npm install --productionto install the dependencies,gulpto compile,
then copy the contents of the newly created dist/ directory to your server. Set the access rights for dist/data/: the process running PHP has to have write access, while everyone else should have neither read nor write access.
For development, run
npm installto install the dependencies including dev,gulp watchto compile and wait for changes.
See gulpfile.js for more tasks.
