I'm hoping to create a link to a .pdf document from using a Prefix/FIELD/FIELD.pdf
Based on file:///G:/GIS/BV_Water/PDF_WS_CARDS/ABBOTT%20ST/6%20ABBOTT%20ST.pdf
which will on our internal server...
Take a look at the following article:
FAQ: Is it possible to create hyperlinks for data stored in a local drive in an ArcGIS Online web map?
In the Field Calculator, choose Python and use a syntax very similar to the following:
"<a href=" 'domainURL'+""+ !FIELD1!+""+!FIELD2!+" "+'target="_blank" ' ">PDF</a>"
Hopefully this works for you. Try not to mismatch single quotations with double quotations.
