Create an external link for a pdf where the filename is stored in a tiddler field.

[si]

I have tiddlers for books with the title of the book stored in a field called "book-title", and I want to create a link to the pdf of the book.

For example say I have a tiddler containing the field "book-title=[[Oliver Twist]]".

I want to create a template to generate a link of the form "[ext[Oliver Twist|.\books\Oliver Twist.pdf]]".

I have tried "[ext[{{!!book-title}}|.\books\{{!!book-title}}.pdf]]" but this doesn't work.

If anyone can help me out I would really appreciate it.

Thanks in advance.

In order to construct wikitext syntax that inserts a value from a field, you first need to create a macro definition, like this:

\define book-link(title) [ext[$(title)$|.\books\$(title)$.pdf]]

Then, to use it, you would write:

<$vars title={{!!book-title}}><<book-link>></$vars>

Let me know how it goes...

enjoy,
