! Introduction
The setmultiplevariables widget assigns values to multiple [[variables|Variables]] where the names and values of the variables are specified as separate filter.
! Content and Attributes
The content of the `<$setmultiplevariables>` widget is the scope for the value assigned to the variable.
|!Attribute |!Description |
|$names |Filter evaluating to the names of a list of variables to assign |
|$values |Filter evaluating to the values corresponding to the list of names specified in `$names` |
! Examples
Here is an example of a convoluted way to display the values of the fields of the tiddler "HelloThere":
<$macrocall $name='wikitext-example-without-html'
src="""<$setmultiplevariables $names="[[HelloThere]fields[]addprefix[demo-]]" $values="[[HelloThere]fields[]] :map[[HelloThere]get<currentTiddler>]">
<ol>
<$list filter="[variables[]prefix[demo-]sort[]]">
<li>
''<$text text={{{ [<currentTiddler>removeprefix[demo-]] }}}/>'': <$text text={{{ [<currentTiddler>getvariable[]] }}}/>
</li>
</$list>
</ol>
</$setmultiplevariables>"""/>
