New Tiddler button with title from another tiddler's field

[Alex Hough]

Dear All,

I have this button..

<$button message="tm-new-tiddler" param={{InvoiceTemplate!!invoice-title}}>New Invoice</$button>

InvoiceTemplate!!invoice-title contains {{!!customer}}, {{!!period-name}}

I want to generate a new invoice with the name of the customer and period

I can transclude from the Tiddler itself, like this

<$button message="tm-new-tiddler" param={{!!invoice-title}}>New Invoice</$button>

but what I get is "{{!!customer}}, {{!!period-name}}" as the title when I try to get the field from the InvoiceTemplate field

What am I doing wrong?

Hi Alex,

No idea how to do it with the core but

you can use tobibeer/make with tobibeer/setvars to achieve the desired result:

<$setvars
_make="[[]make[{{!!customer}}, {{!!period-name}}]]"
new-title="[make[][][]]">
<$button message="tm-new-tiddler" param=<<new-title>>>New Invoice</$button>
</$setvars>

Demystified:

• [make[][][]]
• evaluate the attribute _make as a filter and...
• not specifying an item range, so taking all titles ...well there is just one bering 
• not specifying any empty value ...because it's never going to be empty
• joining all items to a string ...not using any separator
  
• [[]make[{{!!customer}}, {{!!period-name}}]]
  
• create a unique title based on the customer and period-name fields of the current tiddler

You can also use the make filter to create a unique, zero-padded invoice number that is unique among all invoices and simply incremented with every new invoice.

Best wishes,

Tobias.
