1) so-layers now run every parameter through either addslashes of intval, to prevent query-insertion and for pgSql 7.3 compatibility

Browse Source 
2) corrected the escapeing of " and '
3) added some inline-docs

@abstract generalized linking between entries of phpGroupware apps - BO layer @abstract generalized linking between entries of phpGroupware apps - BO layer
@discussion This class is the BO-layer of the links @discussion This class is the BO-layer of the links<br>
@discussion Links have two ends each pointing to an entry, each entry is a double: Links have two ends each pointing to an entry, each entry is a double:<br>
@discussion app app-name or directory-name of an phpgw application, eg. 'infolog' app app-name or directory-name of an phpgw application, eg. 'infolog'<br>
@discussion id this is the id, eg. an integer or a tupple like '0:INBOX:1234' id this is the id, eg. an integer or a tupple like '0:INBOX:1234'<br>
The BO-layer implementes 2 extra features on top of the so-layer:<br>
1) It handles links to not already existing entries. This is used by the eTemplate link-widget, which allows to
setup links even for new / not already existing entries, before they get saved.
In that case you have to set the first id to 0 for the link-function and pass the array returned in that id
(not the return-value) after saveing your new entry again to the link function.<br>
2) Attaching files: they are saved in the vfs and not the link-table (!).
