I'm a complete newbie regarding OJS. I have intermediate knowledge and experience with HTML and PHP.
A friend of mine has asked me for help to add a download counter for every publication that is available on PDF format on their OJS website.
For example:http://www.gmjei.com/journal/index.php/ ... ue/current
Every hyperlink labeled "PDF" on that page, has to have an individual counter and download statistics must be viewable to the public user. There are hundreds of PDF publications in the site in other pages (other months, for example).
Is there any plug-in available for this functionality? If not, I can develop a PHP application to count the number of downloads, but I wouldn't know where to add it in the OJS source files and how to make my program differentiate one PDF from another since I don't have any experience with the OJS structure.
I would really appreciate your help on this matter.
