How to do a second, third, etc tags field in edittemplate?

[Dave Gifford - http://www.giffmex.org/]

Hi guys

I know it's been a long time. Got a question for you all:

Is there a way in edittemplate to create a custom edit tag field so
that I can assign a tiddler a tag within a special category of tags?
Kind of like a shortcut instead of doing formtemplate and
datatemplate?

Here's the setup: I'm doing a database of hymns. The list of tags will
be normal. But a certain hymn might be found in different hymnals with
different #s. So I'd like to create a special edit tags field for each
hymnal, then type in the hymn number in that hymnbook's field in edit
mode, then have a foreachtiddler code pull that number and put it into
a table.

Is this doable, or do I need to use datatemplate and formtemplate for
this?

Add custom tiddler fields is very easy... First, add something like
this to your EditTemplate:

<div class='editor' macro='edit othertags'></div>

Then, to access the stored value in a <<forEachTiddler>> macro, you
can write something like:

tiddler.fields['othertags']

Note: the fieldname (e.g., 'othertags') must be all lower case.

Thanks for the quick reply, Eric!

The edittemplate fix is awesome. Very helpful.

But the FET code doesn't work. Rather than use othertags, I used sdg.

When I do:

<<forEachTiddler where 'tiddler.tags.contains("SDG")'
write '"|[["+tiddler.title+"]]|SDG:"+tiddler.fields['sdg']+"|"'
>>

I get

<<forEachTiddler ...>>: Extra parameter behind 'write': sdg']+"|"'

It tells me that tidder.fields is not a

When I do:

<<forEachTiddler where 'tiddler.tags.contains("SDG")'
write '"|[["+tiddler.title+"]]|SDG:"+tiddler.sdg+"|"'
>>

It looks better but what should show the tag from sdg comes up as
undefined.

write '"|[["+tiddler.title+"]]|SDG:"+tiddler.fields("sdg")+"|"'>>

Gives me

<<forEachTiddler ...>>: TypeError: tiddler.fields is not a function

You have to be careful about mixing up your single and double quotes.
There are single-quotes around the write '...' clause. Thus, you
can't use single-quotes *within* that clause...

Thus, write:
write '"|[["+tiddler.title+"]]|SDG:"+tiddler.fields["sdg"]+"|"'

note: tiddler.fields is an *object*, not a function. Thus,
tiddler.fields["foo"] is a reference to the "foo" property of the
tiddler.fields object.

Thanks that did the trick. I could have sworn that I tried that option
too, among my experiments, but I guess not.
