new Citation($parms)

Up: class Citation

The constructor for an instance of Citation takes one parameter:

parameter	description
$parms	identifies the database record to be associated with this instance. This is an associative array.

$parms may be:

• An associative array containing all of the fields in a record as obtained by a database SELECT.
• An associative array containing the option 'idsx' => integer that specifies the unique numeric key of the record in the table that is to be used to initialize the new instance, plus optional additional field name value pairs to modify the record retrieved from the database.
• An associative array that does not contain the option 'idsx' => integer requests the creation of a new record. The optional additional field name value pairs initialize the new record. The array may be empty in which case the new instance is created with all default values.
• Omitted, in which case a new instance is created with all default values.

In the optional additional field name value pairs one field name has special support:

field name	interpretation
'idsr'	this may be either a positive integer or else an instance of class Source.

The constructor adds error messages to $record->msg if it is unable to complete due to bad parameters.
