How to add variables in tags

[davidbeijinho]

I'm trying to create a new button with today date as a tag how can I achieve this?

<$set name="todayDate" value=<<now "DD MMM YYYY">>>
  <$button class="tc-btn-invisible">
  <$action-sendmessage $message="tm-new-tiddler" title="This is newly created Task" tags="[[task]] [[other]]  [[I_WANT_THE_DATE_HERE]]" text=<<todayDate>>/>
    New task for today
  </$button>
</$set>

It's better to use the "actions" parameter for buttons. It will update all parameters if the button is clicked.

If the actions are inside the button, the parameters are updated, when the button is rendered.

\define myActions()
  <$action-sendmessage $message="tm-new-tiddler" title="This is newly created Task" tags="[[$(todayDate)$]] task other" text=<<todayDate>>/>
\end

<$set name="todayDate" value=<<now "DD MMM YYYY">>>
  <$button class="tc-btn-invisible" actions=<<myActions>> >
    New task for today
  </$button>
</$set>>
