Model for forums

Models don't share that much, so most implementations will be adding methods onto this class. This class simply provides helper methods for common actions.

package XenForo_Forum

 Methods

Constructor.

__construct() 
Inherited

Use create() statically unless you know what you're doing.

inherited_from \XenForo_Model::__construct()

Adds a join to the set of fetch options.

addFetchOptionJoin(array $fetchOptions, integer $join) 
Inherited

Join should be one of the constants.

inherited_from \XenForo_Model::addFetchOptionJoin()

Parameters

$fetchOptions

array

$join

integer

Adds the equivalent of a limit clause using position-based limits.

addPositionLimit(string $table, integer $limit, integer $offset, string $column) : string
Inherited

It no limit value is specified, nothing will be returned.

This must be added within a WHERE clause. If a clause is required, it will begin with "AND", so ensure there is a condition before it.

inherited_from \XenForo_Model::addPositionLimit()

Parameters

$table

string

Name of the table alias to prefix. May be blank for no table reference.

$limit

integer

Number of records to limit to; ignored if <= 0

$offset

integer

Offset from the start of the records. 0+
