finished changing class.topic.php  tried creating new help topics, worked fine. tried creating a new ticket as a client, that worked as  well.i've gone 3 levels deep on the topics,  select a topic with only 1 level i get{"media","html"}   after the contact details,selecting a topic with 2 levels of depth, i get the same after selecting the 2nd level topic.selecting a topic with 3 levels of depth (no spaces in any of the topics), i get the same after selecting the 3rd level topic.getting some really messed up stuff on a selection with a custom form, but that may be related to something else. going to wipe out custom forms and existing help topics and test again. in the meantime, i've attached the modded 1.9.4 files i'm currently using.

i can't get any further with this. i'm not sure if some custom forms / lists that i was playing around with before is causing some issue. i deleted all custom forms, but can't delete some custom lists because it say's they're in use by custom forms?!?looking at it, it looks like when the final option is selected, it's trying to call a dynamic form, which is being returned null values, when i don't believe if should be even calling it. i've deleted some of the custom form / list stuff i found still lurking in the database, but may have missed stuff.i'm now going to try going back to a new clean install and re-applying the mod and see how it works on that.in the meantime, once it's working fully, i'd like to see only the 1st drop down list, with the others only showing up, if required, once a selection in the parent drop-down has been made. the created page code shows the inactive drop-downs as disabled, anyone know how to make it so they're hidden?<select name="topic2" disabled="" class="cmb" id="cmb2" style="width: 300px; float: none;">                                         </select>

Thanks nhybgtvfr, Everything works fine only one problem. I have 3 level and after the selection of third level I get {"media","html"}. 

yep. getting the same thing myself, just restarted it all with a completely new database, to confirm it wasn't anything else left over from custom forms causing it, but i still get the same thing. even like this, as far as i can tell, creating a new ticket still works without any problems. i tried before with a custom contact form, and it made a complete mess of that, with html tags and symbols showing up all over the place.your custom ticket details part looks ok though, so maybe anything other than a customised contact form may be ok.looking at the code some more, it looks like the help topic drop downs and the contact form are being created within the same tbody /tbody tags, with ticket details and captcha each in their own tbody, i *think*  the help topic part and the contact details part should both be in their own tbody. but i'm in no way, shape or form, a programmer, i've managed to hack it this far, but i think someone with a bit more knowledge than me will need to fix this part.

ok. the remaining issue has nothing to do with the contact form being in the same tbody, that said, i still think the contact form *should* be in it's own tbody, which can be achieved by editing include/client/open.inc.php and adding</tbody><tbody>just above these lines:<?php        if (!$thisclient) {            $uform = UserForm:()->getForm($_POST);the issue is being displayed by this bit of code:    <tbody id="dynamic-form">        <?php if ($form) {            include(CLIENTINC_DIR . 'templates/dynamic-form.tmpl.php');        } ?>    </tbody> i've moved it to the end of the table, so it doesn't affect any of the other forms.its being called by this bit of code, in the same file, with the highlighted line being the cause. i've commented the line out, and the issue no longer displays, although i can't confirm that won't cause any other issues. not worked through that part yet.var changeCombo = function(){    var value = $("#cmb_value").val();    var data = $('', '#dynamic-form').serialize();    if(value ==""){        $('#dynamic-form').html("");    }else{        $('#dynamic-form').load('ajax.php/form/help-topic/' + value , data);    }}

ok, you can't just comment out the line below, if you do, it will not load any custom forms.        $('#dynamic-form').load('ajax.php/form/help-topic/' + value , data); the actual data being returned by 'value' in that line appears to be fine, it matches up with my help topic id's. there doesn't appear to be anything spurious being included.when there are no custom forms it just displays {"media","html"} , i have no idea where it gets this from, they're not in the database, and the strings media and html only appear together in include/mpdf/classes/cssmgr.phpif you do use a custom form, it appears on screen, mangled, like:\n\nAffected Site<\/h3>\n<\/em>\n <\/div>\n <\/td><\/tr>\n\n Website URL::<\/label>

I think they are getting the values from this file include/class.forms.php

well, i don't seem to be getting any further with this. looks like i'm gonna have to leave this one to someone with some real programming knowledge.

Hello guys,

Here's the code as promised. I made the change pretty quickly cause I have a short delivery time, so don't judge my coding skills hahaha. The 3 files I changed are the following:

C:\wamp\www\osTicket\open.php

C:\wamp\www\osTicket\include\client\open.inc.phpC:\wamp\www\osTicket\include\class.topic.php

I'm attaching them here in a 7zip folder. Just by repleacing those files it should be working right away. Let me know If you have any problems.

Jerry

Thanks!! That worked PERFECTLY!
