This patch introduces some core changes, basically I moved some code from edit_entry.php to new functions. This means that the web interface must be tested: Create a new glossary, selct Display format (Entry list) Create glossary categories (when browsing the glossary, go to browse by category and you sill see a link to Edit categories And create new entries, testing that all the settings works correctly (categories, keywords (aliases), attachments, inline attachments etc.. Check that the new entries are created correctly and that you can edit them without any issue Once you have finished, you can test the new Web Service: As admin, enable "Mobile services": Plugins ► Web Services ► Mobile Create a Token for one user: Click on Site administration ► Plugins ► Web services ► Manage tokens Next, you can do a CURL REST call simulating a WS client with the user. You need to replace the wstoken, glossary instance id with your own and the URL of your moodle instance curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'glossaryid=1&concept=Something&definition=the_definition&wsfunction=mod_glossary_add_entry&wstoken=ffbe3a3002f235bf9d01fd9369e10b66' | python -m "json.tool" # Check that the new entry was created, it can be in the approval list if you are using a token for a student user Run again the curl command an check that you get an exception: errconceptalreadyexists Now, add a options parameter, indicating additional options like aliases and categories: &options [0] [name] =categories&options [0] [value] =1&options [1] [name] =aliases&options [1] [value] =alias1,alias2 Check that the new entry is created with the alias and in the sections You can play with the rest of optional options like usedynalink casesensitive fullmatch If you want to attach files, you need to upload them to get the attachmentsid, for upload files you can do: curl -i -F filedata=@/Users/juanleyvadelgado/Documents/fast http://localhost/m/stable_master/webservice/upload.php?token=ffbe3a3002f235bf9d01fd9369e10b66&filearea=draft " You will get an itemid that you can use as attachmentsid
