I have to add one field to step 3 (an editors introduction/summary to the article) in the submission form. Loosely following this example http://pkp.sfu.ca/support/forum/viewtopic.php?f=8&t=2731#p9820
I tried to insert the new field into the following files, adding my new field whereever I found references to the 'abstract' field, which I use as a guideline:
lib/pkp/classes/submission/Submission.inc.php (set & get)
The additional field does show in the submission and review forms, yet its contents are not saved. I guess I have to add the name new field to a class or model definition, but I couldn't find exactly where that belongs. Any help would be much appreciated!
