Custom field question

[axelm]

Is there a way to do this:

If a field contains a certain value, that a tag is added to the tiddler automatically?

Isn't it possible, to create the tags and the field together?

When should the tag be created?
eg: you have 3 tiddlers with a field and no tags
- Should there be a button, which iterates all tiddlers and add tags
- ...

-m

I have a plugin (ToDoPlugin) that creates a field called "tdptask0", but only when there is a ToDo item.
What I would like to have is that at the same time a tag would be attached to the tiddler.

Maybe, is there a script that can run when you close the tiddler?
The script could then check if the field is NOT empty and add the tag?

If the plugin code is already adding a field to the tiddler, it would
seem relatively straightforward to modify the plugin to also tag that
tiddler at the same time.

Assuming you start with just a tiddler title, you need to get the
tidder object (if not already done by the plugin code), add a tag to
that object's 'tags' array, and save it back to the store:
var title="SomeTiddler";
var tid=store.getTiddler(title);
tid.tags.pushUnique("someTag");
store.saveTiddler(tid.title,tid.title,tid.text,tid.modifier,new
Date(),tid.tags,tid.fields);

enjoy,

Oh that sounds exactly like what I need.
But I have no idea how to "modify" a plugin.
Where would I add this code?

This is the plugin that adds the "tdptask0" field:

so close...
