Limit Plugin to Certain Categories and Discussion Types

I love this plugin: https://open.vanillaforums.com/addon/extradiscussiondata-plugin

It is a plug that allows you to add extra discussion data.

However, I cannot limit it to a certain category in my forum. If I enable it, all the extra discussion data pops up on every new post made by every user. I only want this to occur in one specific category.

Additionally, I want it it to only operate when a user selects "Ask a Question" discussion option in a specific forum category. How do I set the permissions for this or modify the code to check for this logic: If category = A && user activates QnA plugin, then activate extra discussion data plugin.

Also , I would like for this data to auto populate based on previous entries. If my extra field is an entry for 'Fruit' and there are five entries for Apple, I want it to have an autocomplete option when the user types in the letter 'A'.

Lastly, when I use this plugin, it doesn't have a line break between the extra data. How do I add a line break?

Sorry if this is asking too much. I am just trying to incorporate some information I found on this board in order to essentially combined this plugin with the Q&A plugin.

Thanks!

    How good are your programming skills? It would require mostly Javascript knowledge.

    You would have to add a JavaScript which hooks to the category-dropdown change event. I once did this for a plugin and this is the script I've used.

    You would have to additionally control the change event for the ask a question/new discussion button to allow this only for questions.

    For the autocomplete part you might use jquery.tokeninput.js which comes with Vanilla.

    I have programming skills but not web dev skills.

    I feel there must be a simpler way to achieve this. I am looking at the code in 'extradiscussiondata-plugin' and there is an element that checks for

    ($RequestMethod == 'discussion')

    Surely there must be a way to simply get if the discussion type is QnA or Discussion and if it is Discussion 'extradiscussiondata-plugin' is allowed to run.

    I've tried inserting this around the entire contents of the plugin:

    if ($Sender->Data('Discussion.Type') == 'QnA')
    // plugin contents pertaining to post controller
    }

    But that does not work.

  • I just posted a comment and now it's gone? Hmm

  • Anyways, I've tried a lot of thins and nothing seems to work.

    I tried writing an if statement saying :

    if ($RequestMethod != 'discussion') {

    But that does not work. I feel this should be really simple. Don't understand why it requires a js hook. This is a php plugin that is dependent on a button press (either QnA or Discussion) which is interpreted as a RequestMethod of some sort.

    What am I missing?

    Your comment got caught in the spam filter. It's back now.

  • @hgtonight , not sure if you've revisited this plugin since January 2017, but I'd like to work together to increase the functionality of this plugin.

    You are correct, sorry for leading you in the wrong way. This is taken from the QnA plugin:

        public function postController_beforeDiscussionRender_handler($sender) {
            // Override if we are looking at the question url.
            if ($sender->RequestMethod == 'question') {
                $sender->Form->addHidden('Type', 'Question');
                $sender->title(t('Ask a Question'));
                $sender->setData('Breadcrumbs', [['Name' => $sender->data('Title'), 'Url' => '/post/question']]);
            }
        }
    

    As you can see, you would have to check the PostControllers property RequestMethod.

    But this remains true. If you click the New Discussion/Ask a Question button from the homepage, you will see a Category dropdown. If you want to add a functionality only for some categories, it is good UX to disable those additional form controls for the category where they are useless/not allowed.

    If you show us some of your code, we might be able to asist.

  • @R_J , I deleted my code. I got really frustrated.

    I'll try again tomorrow and post what I end up with.

    This is what I have in

    class.discussionextender.plugin.php

    public function PostController_BeforeFormInputs_Handler($Sender) {
    $RequestMethod = strtolower($Sender->RequestMethod);
    if ($RequestMethod == 'editdiscussion') {
    $this->AddExistingDiscussionFieldData($Sender->Form, $Sender->Data('Discussion'));
    $this->RenderDiscussionFieldInputs($Sender->Form, 'cat');
    }
    else if ($RequestMethod == 'question') {
    $this->RenderDiscussionFieldInputs($Sender->Form, 'cat');
    }
    }

    All I did was change this line:

    else if ($RequestMethod == 'discussion') {

    to this:

    else if ($RequestMethod == question') {

    I also tried:

    else if ($RequestMethod != 'discussion') {

    None of these work.

    Cannot get the js hook method to work, like I said, I deleted that code and will try again tonight.

    What is frustrating is that if I insert this bit of code in class.discussionextender.plugin.php:

    echo $Sender->RequestMethod;

    I get either 'question' or 'discussion' as the response depending if I click on 'Ask a Question' or 'New Discussion'.

    However, if I do an if statement to allow the extra discussion data by checking the 'RequestMethod', it doesn't work. Yet I can write this if satement and have it perform as expected. What is going on?

    `$TheType =$Sender->RequestMethod;`
    `$Condition = 1;`
    `if ($TheType == 'discussion') {`
    `   $Condition = 3;`
    `}`
    
    `   echo $Condition;`
    

    }

    I might have taken a look at the plugin before answering you. I just downloaded it in order to be able to support. This plugin takes a config file and I guess you are trying the code above in the part below, correct?

        $Config['ShowFormWhen'] = function($Sender) {
            // Some logic based on $Sender->Discussion here
            return true;
        };
    

    Your problem doesn't lie here, though...

    The Q&A plugin works by replacing the post view and this is a good example why this should be done...
    If you look at the original view (\applications\vanilla\views\post\discussion.php) from line 50 to 65 you see that there are "DiscussionOptions".

    But looking at the Q&A plugins view (\plugins\QnA\views\post.php) somewhere between $this->FireEvent('BeforeBodyInput'); and $this->FireEvent('AfterDiscussionFormOptions'); you will see that those discussion options aren't printed out for questions.

    The plugin ExtraDiscussionData extends the discussion options which are not available on a question.

    I would consider it being a bug that the Q&A plugin doesn't implement that part of the post view. So if you want to get your program up and running you would have to change one of both plugins. I think changing the Q&A plugin makes more sense and you should make a PR on GitHub to implement that change.

    Search the line $this->FireEvent('AfterDiscussionFormOptions'); \plugins\QnA\views\post.php

    and make it look like that:

        $Options = '';
        // If the user has any of the following permissions (regardless of junction), show the options.
        if (Gdn::session()->checkPermission('Vanilla.Discussions.Announce')) {
            $Options .= '<li>'.checkOrRadio('Announce', 'Announce', $this->data('_AnnounceOptions')).'</li>';
        }
    
        $this->EventArguments['Options'] = &$Options;
        $this->fireEvent('DiscussionFormOptions');
    
        if ($Options != '') {
            echo '<div class="P">';
            echo '<ul class="List Inline PostOptions">'.$Options.'</ul>';
            echo '</div>';
        }
        $this->fireEvent('AfterDiscussionFormOptions');
    

    Afterwards you should be able to use

            if ($Sender->RequestMethod == 'discussion') {
                return false;
            }
    

    in the config of the ExtraDiscussionData plugin.


    By the way: I guess you have confused the plugin author. It is @JasonBarnabe and not hgtonight you wanted to ask for cooperation...

  • I am not using the "ExtraDiscussionData" plugin.

    I am using the "DiscussionExtender" plugin.

    @R_J , thanks for all the help so far. Sort of seeing the relationship between Gdn and functions. Don't quite understand $Sender and $This, yet.

  • Just realized I made that mistake on my original post.
