How can i display the 2-3 latest questions inside each category in categories list page ??

Question

Hi. I am trying to display 2-3 last questions of each category at the categories list.

eg:

Computers - (52 Questions) - 1st question title, 2nd Question title

Tablets - (10 Questions) - 1st question title, 2nd Question title

ETC

Any idea from @Scott @sama55  ???

The ideal would be to add a function inside my advanced theme file but it also ok for me if i can add that function inside the categories List core file as well

Thanks in advance for your help guys .

Any help as it really drives me crazy ??

It will not be difficult to add this feature. However, if there are many categories (50, 100, 200 ...), category page performance will be worse with simple logic.

@sama55 i have only 12 categories so i guess it wouldn't be a problem for site performance. Could you guide me please ? Thanks in advance.

Answer 1

1. Create your layer plugin
2. Add function below

public function nav_link($navlink, $class) {
    qa_html_theme_base::nav_link($navlink, $class);
    if($class == 'browse-cat') {
        $questions = qa_db_single_select(qa_db_qs_selectspec(qa_get_logged_in_userid(), 'created', 0, $navlink['label'], null, false, false, 3));
        if(count($questions)) {
            $this->output('<ul class="qa-'.$class.'-qs">');
            foreach($questions as $id => $question) {
                $this->output('<li>');
                $this->output('<a href="'.qa_q_path_html($id, $question['title']).'">');
                $this->output(qa_html($question['title']));
                $this->output('</a>');
                $this->output('</li>');
            }
            $this->output('</ul>');
        }
    }
}

Note:

Page display performance is not guaranteed.

I did exactly what you suggested but didnt work. Actually you forgot to add "class qa_html_theme_layer extends qa_html_theme_base { " before the function :)

In the admin panel shows the plugin my-layer but in the front end when i click on the categories page it displays the categories as it was before the plugin (without listing the questions inside each category)

Did i miss something ??
Thanks

It works properly in my test environment.

Learn how to make layer plugins on the following page.
http://docs.question2answer.org/plugins/layers/

And also, you can confirm that above function is running by echo.
For example ...
public function nav_link($navlink, $class) {
    qa_html_theme_base::nav_link($navlink, $class);
    echo 'This is function of my layer.'; // <= !!!
    if($class == 'browse-cat') {
...
}
If "This is function of my layer." is not shown, nav_link() function is not called by something cause. In this case, it is possible that your theme or any plugin has stopped layer function chain.

Thanks for your answer @sama55 i will check it asap and will let you know what i was doing wrong :)

UPDATE: i passed the echo in the function and it is displayed on each category, but the questions aren't. i double checked the code everywhere and is exactly as you mentioned above. !!!!!!!!!!!!!!!!!!!!

$questions may be 0 (Zero).

public function nav_link($navlink, $class) {
    qa_html_theme_base::nav_link($navlink, $class);
    if($class == 'browse-cat') {
        echo 'label = '.$navlink['label']."<br/>"; // Category name
        $questions = qa_db_single_select(qa_db_qs_selectspec(qa_get_logged_in_userid(), 'created', 0, $navlink['label'], null, false, false, 3));
        echo 'questions = '.count($questions); // Result set
        ...
}
