Module:DYK

This module is responsible for the functionality of the Did you know? facts that appear on the main page. It does this by randomly pulling a number of facts from the content of the Dogcraft Wiki:Did you know/Facts page.

Functions:

random

The "random" function can generate up to 5 random numbers per day. Its arguments are "length", which sets the highest random number it can select (default is 30), and "seed", which can select between the 5 daily numbers. Seed accepts numbers from 1 to 5.
Examples:

• {{#invoke:DYK|random|length=33|seed=1}} generates: 4 (this number changes daily)
• {{#invoke:DYK|random|length=33|seed=2}} generates: 4 (this number changes daily)
• {{#invoke:DYK|random|length=33|seed=3}} generates: 4 (this number changes daily)
• {{#invoke:DYK|random|length=33|seed=4}} generates: 4 (this number changes daily)
• {{#invoke:DYK|random|length=33|seed=5}} generates: 4 (this number changes daily)

randomW

The "randomW" function can generate up to 5 random numbers per week. Its arguments are "length", which sets the highest random number it can select (default is 30), and "seed", which can select between the 5 daily numbers. Seed accepts numbers from 1 to 5.
Examples:

• {{#invoke:DYK|randomW|length=33|seed=1}} generates: (this number changes weekly)
• {{#invoke:DYK|randomW|length=33|seed=2}} generates: (this number changes weekly)
• {{#invoke:DYK|randomW|length=33|seed=3}} generates: (this number changes weekly)
• {{#invoke:DYK|randomW|length=33|seed=4}} generates: (this number changes weekly)
• {{#invoke:DYK|randomW|length=33|seed=5}} generates: (this number changes weekly)

facts

The "facts" function, which returns up to 5 facts per day, selected from Dogcraft_Wiki:Did_you_know. Its arguments are "text", which expects "{{Dogcraft_Wiki:Did_you_know/Facts}}" or a similarly layed out page, as the value, and "start" and "end", which determine which of the 5 facts to return.
Example: {{#invoke:DYK|facts|text={{Dogcraft_Wiki:Did_you_know/Facts}}|start=1|end=2}} generates:

(this changes daily)
