Description
The reason why this query shows several entries for distinct test is that the uniqueness requirement refers to the combination of referring page and referred page. Note that a referring page might contain several references to the same page (which you wouldn´t want to see in the listing). DPL offers a variable named %PAGESEL% which shows the referring page. If we add that variable to the example we see why there are several occurencies of distinct test in the output:
Extension:DynamicPageList (DPL), version 3.2.1: Warning: Skipping bad option 'Test distinct|Test distincts|Test distinctes|Test distincties|Test distincting|Test distincted|{{{2}}}|{{{2}}}s' for parameter 'linksto'.
Extension:DynamicPageList (DPL), version 3.2.1: Error: No selection criteria found! You must use at least one of the following parameters: category, namespace, titlematch, linksto, uses, createdby, modifiedby, lastmodifiedby, or their 'not' variants
Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.
Code
{{#dpl:
linksto={{PAGENAME}}{{!}}{{PAGENAME}}s{{!}}{{PAGENAME}}es{{!}}{{PAGENAME}}ies{{!}}{{PAGENAME}}ing{{!}}{{PAGENAME}}ed{{#if:{{{2}}}|{{!}}{{{2}}}{{!}}{{{2}}}s|}}{{#if:{{{3|}}}|{{!}}{{{3}}}{{!}}{{{3}}}s|}}
|resultsheader=<h2>Backlinks (%PAGES%)</h2>
|format=,\n*[[%PAGE%{{!}}%TITLE%]] referenced by %PAGESEL%,
}}
If we set distinct=strict we will only get one result. Note that the value of %PAGESEL% in this case will be not useful.
