FileDuplicateSearchPage::FileDuplicateSearchPage ( hash,
filename 
)

Definition at line 21 of file SpecialFileDuplicateSearch.php.

References $filename, and $hash.

FileDuplicateSearchPage::formatResult ( skin,
result 
)

Formats the results of the query for display.

The skin is the current skin; you can use it for making links. The result is a single row of result data. You should be able to grab SQL results off of it. If the function return "false", the line output will be skipped.

Reimplemented from QueryPage.

Definition at line 49 of file SpecialFileDuplicateSearch.php.

FileDuplicateSearchPage::getName (  ) 

Subclasses return their name here.

Make sure the name is also specified in SpecialPage.php and in Language.php as a language message param.

FileDuplicateSearchPage::getSQL (  ) 

Subclasses return an SQL query here.

Note that the query itself should return the following four columns: 'type' (your special page's name), 'namespace', 'title', and 'value' *in that order*. 'value' is used for sorting.

These may be stored in the querycache table for expensive queries, and that cached data will be returned sometimes, so the presence of extra fields can't be relied upon. The cached 'value' column will be an integer; non-numeric values are useful only for sorting the initial query.

Don't include an ORDER or LIMIT clause, this will be added.

FileDuplicateSearchPage::isExpensive (  ) 

Is this query expensive (for some definition of expensive)? Then we don't let it run in miser mode.

$wgDisableQueryPages causes all query pages to be declared expensive. Some query pages are always expensive.

FileDuplicateSearchPage::isSyndicated (  ) 

Sometime we dont want to build rss / atom feeds.

Reimplemented from QueryPage.

FileDuplicateSearchPage::linkParameters (  ) 

If using extra form wheely-dealies, return a set of parameters here as an associative array.

They will be encoded and added to the paging links (prev/next/lengths).

Returns:
array
