Debug

If you see a blank screen you can try to modify:

ini_set('display_errors', '1');

inside includes/config.php.

Self processing

When entering a new question you have the option to process a text into question elements.

1. Add to the "Input Data" column the demo data below:

    What animal is in the picture below?
    *A - giraffe
    B - dog
    C - snake
    D - cow
   

2. In "Input Script"

    var contentArray = content.split("\n");
    var question = contentArray[0];
    var questions = [];
    var answers = [];
    var tmp;
   
    for(var i = 1; i < contentArray.length; i++) {
        tmp = contentArray[i];
        questions.push(tmp.substr(4).trim());
   
        if(tmp.substr(0, 1) == '*') {
            answers.push(true);
        } else {
            answers.push(false);
        }
    }
   

3. Click "process data". This will process the text from the input to the fields in the form above. Now all you have to do is click "add question".

This is specific for the input type.

In this particular case the first line in the script is splitting the text into lines. Lines 2-4 are just defining variables that will be used later. Question will store the actual question which is at the first line (0 for is the first item in JavaScript). Questions will hold the possible answers and answers will contain the correct one (true for correct/false for incorrect).

Line 6 is iterating over the remaining lines (starting from the second, because the first was 0) and adding them to the questions array.

Line 7 is getting the current line and save it into an array.

Line 8 is adding the answer to the questions array starting from the 5th element of the string, to eliminate "*A - " from the string.

Line 10 is getting the first character of the current line to see if it is "*", which in this particular case means the answer is correct.

Line 11-14 is adding true/false to the answers array to mark it as correct or wrong.
