One: I have a table called quizData. It will always contain only 1 row. It
has columns option1, option2, option3, option4, option5 each of type
int. In the beginning, these columns have 0 as their value. How do I add
1 to any column, say option2?
Two:How could I restrict a Registered user to submit a form only once. for example in a article comment form an user can comment only once per article.
From the manual linked above, important part in bold:
- permission to create new content. You can also set total maximum
allowed number of items in parent content type (Max. in Parent), maximum
allowed number of items in parent content type per author (Max. in
Parent/Author) and maximum allowed number of items per author in this
content type (Max. / Author)"
