We just installed v1.9.12 osTicket, and did some minor customizations a couple of days ago. I had added a new item to that same area of the (client-view) navbar. I knew from using osTicket in the past, that I want to encourage client's to use their log-in when creating tickets. However, I do not want to force a customer to sign in, just in case what they are having a problem with is eMail and/or Support Center Sign-In problem.I edited some of the php include files to have comments, which allowed me to figure how/where the various php sections are used.Example:the header.inc.php file has this line added at top:<!-- START support/ include/ client/ header .inc .php begins below -->and this line added at bottom:<!-- FINISH support/ include/ client/ header .inc .php -->If you make that change and then upload header.inc.php to your server, you will see the PHP CODE which populates the navar by "view page source" in your browser(possibly need to add plug-in).I was able to insert this line:<li><a class=" users" href="/login.php">Sign In for Fastest Help</a></li> before the </ul>and it showed the new link just fine, although i have not figured out which icon I want there yet.(I did this to many files, being very careful to add the comment ONLY in the HTML areas of the PHP include files)(Making a mistake in PHP file edits of include files will either throw a php error message, or cause the page to NOT LOAD, so you really have to be careful)Although tedious, it is very useful to do if you really want to have a good idea of how the various files interact.I am glad for hint on where to look for the function(s) which populate the navbar.Also, I just found info on the Bootstrap Ticket Theme available for v1.9.12 osTicket, so I am going to create a new install using that theme, before I do too much more with this.
