Select Fields by prefix

[Drevarr the Old]

Somewhere in here @TonyM provided a method to generate checkboxes based on a data tiddler which I promptly incorporated into a template for creating new tiddlers.  Now instead of having 64 fields, i have a subset depending on what checkboxes are chosen at tiddler creation.

All the fields generated from checkboxes start with the prefix: "act_". The tiddlers have other fields as well that do not start with "act_".

Can someone help walk me through a list filter to select only fields starting with "act_" from the current tiddler and get the field values?

Try this as a starting point to list your fields in a table

<table>

<$list variable="fieldName" filter="[fields[]prefix[act_]]" >

<tr>

    <td><<fieldName>></td>

    <td><$view  field=<<fieldName>> /></td>

</tr>

</$list>

</table>

Christian got it in one is so far as this finds all fields in the wiki and filters only those with the prefix.

If you use [all[current]fields[]prefix[act_]] then it will only get the current tiddlers fields and the list result in the fieldnames, but you could use other filters like object-type[person]] for all tiddlers containing 

For this reason I would use a variable name as Christian has, so that you can continue to address fields in the currentTiddler
