multi_field
{multi_field="summary|body|extended"}
The {multi_field=} variable is the core of the ability to span a weblog entry across multiple pages. Within the variable, you specify a pipe-delimited list of the fields. These are the fields that will be used for each individual page. Here is an example of how the feature works:
1. Let’s say you set up a weblog and it contains (among others) the fields “page1”, “page2”, “page3”, etc.
2.
In your “comments” Template, you set up the {multi_field} variable like so:
{multi_field="page1|page2|page3"}
3. When you initially visit your comment page for an entry, where you have the {multi_field} tag in your Template, you will see the content of your “page1” field, just as if you had used the regular {page1} variable.
4. If your entry has content in the “page2” field then you will see a “next page” link.
5. When you click that link, you’ll see your entry again, but instead of {page1} being displayed, in its place would be {page2}.
6. This would continue with as many variables/pages as needed.
In other words, you’d have to set up the additional fields, and break down the text yourself. It’s not done automagically.
