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!

normal">Hello friends,

mso-fareast-font-family:"Times New Roman";mso-fareast-language">

normal">fixed the problem with {"media","html"}

by reediting the ajax function in the open.inc.php

15.3pt">Just exchange  

$('#dynamic-form').load('ajax.php/form/help-topic/'

+ value , data);

with $.ajax('ajax.php/form/help-topic/' + value,{            data:

data,            dataType:

'json',            success:

function(json) {              $('#dynamic-form').empty().append(json.html);              $(document.head).append(json.media);            }})works like a charm for me!I will add the file as an attachment

15.3pt">Another thing is, that in the multi-dropdown version

the customer would not be able to post a ticket with just the "parent

topic"For Example when you have a topic "A" and

topics "A / B", "A / C" you a forced to use either "A

/ B" or "A / C" but never just use "A"I think is might be clever to give this opportunity to

the user, because sometimes you just don’t know where the problem really comes

from.So I just changedif(sel.attr("disabled") ===

"disabled"){toif(sel.attr("disabled") ===

"disabled" || sel.val() === ""){and it's working as far as i see now.Next thing i want to change is dynamically showing or

hiding of needed or not needed dropdowns.For example when i have a topic with just 2 levels and

one with 3 I don’t want to show the 3rd dropdown when the customer selects the

topic with just 2 levels.i hope all of this was understandable, normally i just

talk English but never write anything ;)

kudos Suntas. This fixes all the problems, at least for now ;)Will it be possible for you to look into adding cascading drop down to other fields too apart form help topic. Thanks

cool. will check it out tomorrow. don't have time right now.would never have worked out that fix myself   :(re: hiding dropdowns, what would be ideal is if it only showed the 1st level dropdown, and then expanded to show each sub-level dropdown only once a selection is made that actually requires it. so even if every help topic has at least 3 levels, only the top-level dropdown is shown when the page is first loaded.

Got it!Now the dropdowns only get displayed when needed.So startingpoint is dropdown 1, dropdown 2 gets displayed after selecting an option in 1 but only if there is anything to select.Just a tiny jquery script and 1 line of php code to hide the dropdowns on start.File is attached!@ bond007: don't know at the moment. I will try to look into it.

Hey bond007I have a few questions about your issue.In your screenshot you have two fields, one called

"Category" and "Sub Category".How did you add them to the form? I presume, that they

are just 2 added field in a custom form with the type "Choices",

correct?And if I understand you correctly your idea is to add

ONE custom form field of type "Choices", put in a few choices in the

form of "A", "B", "A / C", "B / C"

(a.s.o.) and this should generate 2 dropdowns as we have now in the "Help

Topic" section.Frist one with options A and BSecond with options C and D (a.s.o.)Everything right to this point?

looks good. looks like there might be a special case scenario where the 'Select an option' option is actually selected (highlighted in blue) on a sub-level and then one of the parent levels is changed. the highlighted sub-level doesn't get hidden, but is disabled.probably not a big deal, unlikely to be a regular occurrence anyway, but might be worth checking in case it passes another variable through on selection.

Oh, you are right. hmQuite weird, The Script should just hide every select that is disabled.Have to check that....

Hey again!I'm just here to drop a complete pack with all 3 files which are needed to get my changes working, just to make sure you have everything you need in one zip!sosamv and nhybgtvfr made the important changes in the files, I am just the one playing around with them ;)Files are for 1.9.4 (or at least it's the version I'm working with right now)

Frist one with options A and B

Second with options C and D (a.s.o.)

Everything right to this point?Suntas, I am sorry for delayed response. Was busy with some work here.But you got it right, If we could add this to ticket entry form page. 

@Suntas,Awesome tweaks. Works like charm. Thanks so much to you as well as others who have contributed to this mod.Cheers
