Member Function Documentation

doBatchLookups()

NewFilesPager::doBatchLookups ( )

protected

Called from getBody(), before getStartBody() is called and after doQuery() was called.

This will be called only if there are rows in the result set.

Stability: stable

to override

Returns

void

Reimplemented from IndexPager.

Definition at line 181 of file NewFilesPager.php.

References NS_USER.

formatRow()

NewFilesPager::formatRow

(

$row

)

Returns an HTML string representing the result row $row.

Rows will be concatenated and returned by getBody()

Parameters

array | stdClass

$row

Database row

Returns

string

Reimplemented from IndexPager.

Definition at line 192 of file NewFilesPager.php.

References ContextSource\getLanguage(), IndexPager\getLinkRenderer(), NS_FILE, and NS_USER.

getEndBody()

NewFilesPager::getEndBody ( )

protected

Hook into getBody() for the end of the list.

Stability: stable

to override

Returns

string

Reimplemented from IndexPager.

Definition at line 177 of file NewFilesPager.php.

getIndexField()

NewFilesPager::getIndexField

(

)

Returns the name of the index field.

If the pager supports multiple orders, it may return an array of 'querykey' => 'indexfield' pairs, so that a request with &order=querykey will use indexfield to sort. In this case, the first returned key is the default.

Needless to say, it's really not a good idea to use a non-unique index for this! That won't page right.

The pager may paginate on multiple fields in combination. If paginating on multiple fields, they should be unique in combination (e.g. when paginating on user and timestamp, rows may have the same user, rows may have the same timestamp, but rows should all have a different combination of user and timestamp).

Examples:

• Always paginate on the user field: 'user'
• Paginate on either the user or the timestamp field (default to user): [ 'name' => 'user', 'time' => 'timestamp', ]
• Always paginate on the combination of user and timestamp: [ [ 'user', 'timestamp' ] ]
• Paginate on the user then timestamp, or the timestamp then user: [ 'nametime' => [ 'user', 'timestamp' ], 'timename' => [ 'timestamp', 'user' ], ]

Returns

string|string[]|array[]

Reimplemented from IndexPager.

Definition at line 158 of file NewFilesPager.php.

getQueryInfo()

NewFilesPager::getQueryInfo

(

)

Provides all parameters needed for the main paged query.

It returns an associative array with the following elements: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => option array join_conds => JOIN conditions

Returns

array

Reimplemented from IndexPager.

getStartBody()

NewFilesPager::getStartBody ( )

protected

Hook into getBody(), allows text to be inserted at the start.

This will be called even if there are no rows in the result set.

Returns

string

Reimplemented from IndexPager.
