What am I missing here?
<$list filter="[<currentTiddler>fields[][caption]]" variable="thisfield">
<$transclude field={{{ [<currentTiddler>get<thisfield>addprefix["]addsuffix["]] }}}/>
</$list>
You have a couple of syntax errors, and you don’t need the $transclude widget if you are simply using the triple-brace “filtered translcusion” for text-manipulation. You can use it on its own.
<$list filter="[<currentTiddler>fields[]]" variable="thisfield">
{{{ [<currentTiddler>get<thisfield>addprefix["]addsuffix["]] }}}
</$list>
That will try to “linkify” the results of the filtered-transclusion, and you can “force it back to plain text” like this:
<$list filter="[<currentTiddler>fields[]]" variable="thisfield">
<$text text={{{ [<currentTiddler>get<thisfield>addprefix["]addsuffix["]] }}}/>
</$list>
How do I get it from a specific field?
Nevermind, I was making it more complicated than it was:
<$text text={{{ [{!!field-name}addprefix["]addsuffix["]] }}}/>
This did the trick. However, I had to change to actual quotation marks. Thanks for the help.
But, I also needed it transcluded because the output will sometimes include HTML tags.
@RedAsset it all depends on how you want to use the result;
To display it quoted
“<$text text={{!!field-name}}/>”
and many other forms.
With that, the quotation marks would always be present even if the field is not present.
I needed to determine if the field exists first, like this:
<$list filter="[<currentTiddler>has:field[field-name]]">
"<$transclude field="field-name"/>"
</$list>
I did not know how to do this earlier when I asked the question.
Thanks, anyway.
Here are some other ways to address your question; illustrating there are more than one and having different use cases.
This form will get the fieldname value if it contains a value otherwise nothing.
<$list filter="[<currentTiddler>get[field-name]]">
"<$text text=<<currentTiddler>>/>"
</$list>
But returning to your previous form, the following match your requirements;
<$text text={{{ [all[current]get[field-name]] +[addprefix["]addsuffix["]] }}}/>
Or
<$text text={{{ [all[current]get[field-name]addprefix["]addsuffix["]] }}}/>
You could also have a missing output
<$text text={{{ [all[current]get[field-name]addprefix["]addsuffix["]else[empty]] }}}/>
In the above 3 cases, the prefix and suffix is only used if get[field-name] returns a value.
However if the intention was to indicate when empty you could
"<$view field="field-name"/>"
or
field-name: "<$view field="field-name"/>"
or
field-name: "<$view field="field-name">empty</$view>"
In the above 3 cases, View Widget can be used rather than the less tidy textWidget
- The viewWidgets default output is Plain text
- In the last case the contents of the view Widget is displayed if the result is empty.
