Show question content on the main page

Question

Hello,

Several years ago I have created a theme and overwrote the q_item_main function from my theme's qa-theme.php file:

function q_item_main($q_item)
        {
            $this->output('<DIV CLASS="qa-q-item-main">');
            $this->post_avatar($q_item, 'qa-q-item');
            $this->q_item_title($q_item);
            $this->post_meta($q_item, 'qa-q-item');
            $this->q_item_content($q_item);
            
            $this->output('<!--');
            print_r($q_item);
            $this->output('-->');
            $this->output('</DIV>');
            
        }

Today I have updated Q2A to the latest version and the content disappeared. The $q_item array doesn't have content anymore.

I tried to locate a function or file that populates this array, but with no luck...

How can I add content on the main page considering that I can do some php coding?

Thank you!

As far as I can see, the qa-theme-base.php still holds the function. By default it is:

    public function q_item_main($q_item)
    {
        $this->output('<div class="qa-q-item-main">');

        $this->view_count($q_item);
        $this->q_item_title($q_item);
        $this->q_item_content($q_item);

        $this->post_avatar_meta($q_item, 'qa-q-item');
        $this->post_tags($q_item, 'qa-q-item');
        $this->q_item_buttons($q_item);

        $this->output('</div>');
    }

So you open the qa-theme.php and insert the code you need, for example: 

    public function q_item_main($q_item)
    {
        $this->output('<div class="qa-q-item-main">');

        $this->view_count($q_item);
        $this->q_item_title($q_item);
        $this->output("<p>Some Text</p>");
        $this->q_item_content($q_item);

        $this->post_avatar_meta($q_item, 'qa-q-item');
        $this->post_tags($q_item, 'qa-q-item');
        $this->q_item_buttons($q_item);

        $this->output('</div>');
    }

qa-theme-base.php holds all the functions you can override via qa-theme.php

 

> How can I add content on the main page considering that I can do some php coding?

Also use the qa-theme.php and override for example:

        // override main to output own html elements and more
        function main() {
            // teaser to ask
            if(!qa_is_logged_in() && ($this->template=='qa' || $this->template=='questions')) {
               $this->output('<p>Ask here...</p>');
            }
            // default call of the original function
            qa_html_theme_base::main();
        }

Hope that helps.

Thank you for your response!

This worked in previous versions of Q2A, but not in the latest version for some reason. The $this->q_item_content($q_item); function doesn't return anything because the $q_item array doesn't have content in it.

You can check the source code of this page http://golovoladki.ru - I print out the $q_item for each question and none of them have [content] in it:

Well, there is no question content in the question list items. Tip: You can use the plugin mouseover-layer and modify it so that it outputs the content not in the "title" property but below the question. See https://github.com/q2a/question2answer/tree/dev/qa-plugin/mouseover-layer

$q_list['qs'][$index]['title']='<span title="'.qa_html($text).'">'.@$question['title'].'</span>';

becomes

$q_list['qs'][$index]['title'] = @$question['title'].'<br /><span class="yourcssformat">'.qa_html($text).'</span>';

(not tested)

Thank you for this tip!
Now I remember that I was tweaking this plugin.

This was the modified code for old Q2A that populates the [content] element: http://pastebin.com/Qf0KKciH

I didn't realize that updating Q2A also updates the plugins, so didn't research the new plugin's code.
So this is the edited latest mouseover plugin's code that populates the content element in $q_list array: http://pastebin.com/CPPMhruN - it works perfectly!

Thanks everyone for the help!
