| |
| **Get the view count for this article
| |
| *[[#function isCountable]]( $text ) {

| **Tests if the article text represents a redirect
| |
| *[[#function loadLastEdit]]() {
| |
| **Loads everything from cur except cur_text
| |
| **This isn't necessary for all uses, so it's only done if needed.
| |
| ===Data Access===
| |
| *[[#function getTimestamp]]() {
| |
| *[[#function getUser]]() {
| |
| *[[#function getUserText]]() {
| |
| *[[#function getComment]]() {

| |
| ===More Other Methods===
| |
| *[[#function getContributors]]($limit = 0, $offset = 0)
| |
| *[[#function view]]()
| |
| **This is the default action of the script: just view the page of the given title.
| |
| *[[#function insertNewArticle]]( $text, $summary, $isminor, $watchthis )
| |
| **Theoretically we could defer these whole insert and update functions for after display, but that's taking a big leap of faith, and we want to be able to report database errors at some point.
| |
| *[[#function getTextOfLastEditWithSectionReplacedOrAdded]]($section, $text, $summary = '', $edittime = NULL)
| |
| **Side effects: loads last edit if $edittime is NULL
| |
| *[[#function updateArticle]]( $text, $summary, $minor, $watchthis, $forceBot = false, $sectionanchor = '' )
| |
| **Change an existing article. Puts the previous version back into the old table, updates RC and all necessary caches, mostly via the deferred update array.
| |
| **It is possible to call this function from a command-line script, but note that you should first set $wgUser, and clean up $wgDeferredUpdates after each edit.
| |
| *[[#function showArticle]]( $text, $subtitle , $sectionanchor = '' )
| |
| **After we've either updated or inserted the article, update the link tables and redirect to the new page.

| *[[#function validate]]()
| |
| **Validate article
| |
| *[[#function markpatrolled]]()
| |
| **Mark this particular edit as patrolled

| |
| **Add this page to $wgUser's watchlist
| |
| *[[#function unwatch]]()
| |
| **Stop watching a page
| |
| *[[#function protect]]( $limit = 'sysop' )
| |
| **protect a page
| |
| *[[#function confirmProtect]]( $par, $reason, $limit = 'sysop' )
| |
| **Output protection confirmation dialog
| |
| *[[#function unprotect]]()
| |
| **Unprotect the pages
| |
| *[[#function delete]]()
| |
| **UI entry point for page deletion
| |
| *[[#function confirmDelete]]( $par, $reason )
| |
| **Output deletion confirmation dialog
| |
| *[[#function doDelete]]( $reason )
| |
| **Perform a deletion and output success or failure messages
| |
| *[[#function doDeleteArticle]]( $reason )
| |
| **Back-end article deletion
| |
| **Deletes the article with database consistency, writes logs, purges caches
| |
| **Returns success
| |
| *[[#function rollback]]()
| |
| **Revert a modification
| |
| *[[#function viewUpdates]]()
| |
| **Do standard deferred updates after page view
| |
| *[[#function editUpdates]]( $text )
| |
| **Do standard deferred updates after page edit. Every 1000th edit, prune the recent changes table.
| |
| *[[#function setOldSubtitle]]( $oldid=0 )
| |
| *[[#function preSaveTransform]]( $text )
| |
| **This function is called right before saving the wikitext, so we can do things like signatures and links-in-context.
| |
| *[[#function tryFileCache]]()
| |
| **checkLastModified returns true if it has taken care of all output to the client that is necessary for this request (that is, it has sent a cached version of the page)
| |
| *[[#function isFileCacheable]]()
| |
| **Check if the page can be cached
| |
| *[[#function checkTouched]]()
| |
| **Loads cur_touched and returns a value indicating if it should be used
| |
| *[[#function quickEdit]]( $text, $comment = '', $minor = 0 )
| |
| **Edit an article without doing all that other stuff
| |
| *[[#function incViewCount]]( $id )
| |
| **Used to increment the view counter
| |
| ===Event Hooks===
| |
| The onArticle*() functions are supposed to be a kind of hooks which should be called whenever any of the specified actions are done. This is a good place to put code to clear caches, for instance.
| |
| *[[#function onArticleCreate]]($title_obj)
| |
| **This is called on page move and undelete, as well as edit
| |
| *[[#function onArticleDelete]]($title_obj)
| |
| *[[#function onArticleEdit]]($title_obj)
| |
| ===More Other Functions===
| |
| *[[#function info]]()
| |
| **Info about this page
