Dowload old versions of a file from archive
by nguyenkim thuat 08 Jun '12

08 Jun '12

Hi, Is it possible to download old versions of a file (image, pdf ..) with the function MediaWiki::API->download( $params_hashref )<http://search.cpan.org/%7Eexobuzz/MediaWiki-API-0.39/lib/MediaWiki/API.pm#M…>? When I tried to call this function for example with filename * 'File:20120606205541!Test.txt'* which is located in directory images/archive/ I got empty result. According to the documentation of the download function, it means the file doesn't exist on the MediaWiki. *"If the file does not exist (on the wiki) an empty string is returned. If the file is unable to be downloaded undef is returned.*" Thanks.

MW API: Query to list all links on the provided page doesn't return link to files
by volekp 07 Jun '12

Hi, I have a problem with MediaWiki API when trying to get links of all files (images, pdfs, etc ..) which are included in given page. With the MW API I can get the all other links but no links to media files. Ex.: I have a MW with Main Page, which contains following links (all links are working when click on them): .. [[File:Test.txt]] [[Test Page]] [[www.google.com]] .. I use Perl interface to MediaWiki API. Variable $page contents the hash with properties of 'Main Page'. my $query = { action => 'query', prop => 'links', titles => $page->{title}, pllimit => 50, }; my $mw_links = $mediawiki->api($query); but when I write out the content of $mw_links->{query}->{pages}->{$page->{pageid}}->{links}, I get only the titles of the two following links: Test Page Www.google.com I don't get the name of the link to File:Test.txt. I tried to play also with the namespaces (option plnamespace, for ex. plnamespace = 6,) but it doesn't show the link neither. I get the same result when I write it directly to the url: http://localhost/mediawiki/api.php?action=query&prop=links&pllimit=50&title… Am I missing something? Thank you for response. Pavel Volek

Problem with upload file url
by nguyenkim thuat 05 Jun '12

Hi, When uploading a file using the mediawiki API, i use this Url of the Upload page: $url= *" http://localhost/mediawki/index.php/Special:Upload"; *But is this variable configurable*? *I mean* *to get the url in any wiki langagues. Because the french wiki have the different url for this page, for exemple: $url= *" http://localhost/mediawki/index.php/*Spécial:Téléverser*" *instead Best regards.

Get the number of the revision when deleting a file attachment?
by nguyenkim thuat 05 Jun '12

05 Jun '12

Hi, When deleting a file attachment via the Mediawiki::API->edit, how to get the revision number at that moment? For example, when i upload a file, i can find it by the query: *# Find the number of revision of the page which has the id="$id"* * my $query = { action => 'query', prop => 'revisions', rvprop => 'ids', pageids => $id, }; my $result = $mediawiki->api($query); .......................................................................... *But, when deleting a file, we can't use this mechanism. I wonder if the API support a function to get this number of revision? Thanks.

': ' . $mediawiki->{error}->{details}; } else { print "FILE TYPE NOT SUPPORTED\n"; } sub mw_connect_maybe { if ($mediawiki) { return; } $mediawiki = MediaWiki::API->new; $mediawiki->{config}->{api_url} = "$url/api.php"; if ($wiki_login) { if (!$mediawiki->login({ lgname => $wiki_login, lgpassword => $wiki_passwd, lgdomain => $wiki_domain, })) { print STDERR "Failed to log in mediawiki user \"$wiki_login\" on $url\n"; print STDERR "(error " . $mediawiki->{error}->{code} . ': ' . $mediawiki->{error}->{details} . ")\n"; exit 1; } else { print STDERR "Logged in with user \"$wiki_login\".\n"; } } } To test the type of file supported, i have to use this variable: * my @extensionFiles = ("png","gif","jpg","jpeg","doc","xls","mpp","pdf","ppt","tiff","bmp","docx", "xlsx", "pptx","ps","odt","ods","odp","odg","txt"); *if the file name *$name* is not in the array, I'll generate a message error. : *print "FILE TYPE NOT SUPPORTED\n"; *My question is if the user change the type of file supported in the * LocalSettings.php* , this programme is not true any more. How can i get the array *$wgFileExtensions* from the *LocalSettings.php*? Thank. * *

Hi, when enumerating file pages (File:...), I need to specify namespace to be enumarated so when makeing the query I set "apnamespace=6". But my question is, whether the id of namespace of media files is always the same (in every instalation of mediawiki), always "6". Thanks a lot. Pavel
