Changeset 31951 for main/trunk/greenstone2/macros/deposit.dm

Timestamp:

Message:

Bugfix to depositor: commas in metadata entered through the depositor were not being preserved, as commas were used to split the many fields (of form cgi params) on in depositoraction.cpp. Now depositor.dm escapes the commas with URL encoding in the metadatafields section of the depositor step1 form, while depositoraction.cpp decodes the URL-encoded commas again.
