getReferencesFromString()

ilDclReferenceRecordFieldModel::getReferencesFromString (   $stringValues )

protected

This method tries to get as many valid references out of a string separated by commata.

This is problematic as a string value could contain commata itself. It is optimized to work with an exported list from this DataCollection. And works fine in most cases. Only areference list with the values "hello" and "hello, world" Will mess with it.

Parameters

$stringValues

string

Returns

int[]
