You can also create IDs based on a counter, so you can be sure to avoid
name conflicts, and each tiddler will be given a unique ID (even one that
does not have a created field). In this case, also modify the body of the
generateID function and the filterAlreadyRenamed filter.
var filterAlreadyRenamed = "!regexp[^ZK\\d{8}$]";
// ...
var lastId =
(parseInt($tw.wiki.filterTiddlers("[regexp[^ZK\\d{8}$]nsort[]last[]removeprefix[ZK]]")[0])
+ 1) || 1;
function generateId(fields) {
var idLength = 8;
var idPrefix = "ZK";
var id = lastId.toString();
lastId += 1;
while (id.length < idLength) id = "0" + id;
return idPrefix + id;
}
