How to add category name and date to intro_image.php file in Joomla 3?

Question

Joomla

Hello everyone !
I have a file:

templates/my_template/html/layouts/joomla/content/intro_image.php

I need to insert a code into it that would display the name of the category that includes the material whose intro image is displayed on the site + add the publication date of this material ... That is, I need to transfer the category name and publication date of the material from blog_item EXACTLY to the file

templates/my_template/html/layouts/joomla/content/intro_image.php

I don’t understand how to do this ...
I tried it in different ways:

$this->category->text
$this->category->title

and a bunch of other code like:

$title = $this->escape($displayData['item']->category_title);

Nothing happens... I do n't want to write
queries to the database so as not to load the server once again. I would like to somehow play around with Joomla files, because the whole point is that the category itself (its name and link) is formed in the file

templates/my_template/html/layouts/joomla/content/info_block/category.php

and the date of publication in

templates/my_template/html/layouts/joomla/content/info_block/publish_date.php

But, in order to get to them from the same blog_item , there is a long line with a check:

if ($useDefList && ($info == 0 || $info == 2)) :
echo JLayoutHelper::render('joomla.content.info_block.block', array('item' => $this->item, 'params' => $params, 'position' => 'above'));
endif;

which "forces" to go through several more (above) files... Just copy the code from these files and paste it into intro_image.php - it doesn't work...
Paste the code from blog_item.php:

echo JLayoutHelper::render('joomla.content.info_block.block', array('item' => $this->item, 'params' => $params, 'position' => 'above'));

in intro_image.php - not possible, because the exceptions pop up...
Can someone tell me how to do this?
Thanks in advance for your replies !

Answer 1

It turned out that you can still do without a query to the database ...
It was enough to
create 2 files:

1. category_title.php, in which to write this:

   <?php defined('JPATH_BASE') or die;
     echo $this->escape($displayData['item']->category_title);
   ?>

2. publish_date_no_html.php, in which to write this:

   <?php defined('JPATH_BASE') or die;
     echo JHtml::_('date', $displayData['item']->publish_up, JText::_('DATE_FORMAT_LC2'));
   ?>

and in blog_item.php add:

$cat_name = JLayoutHelper::render('joomla.content.info_block.category_title', array('item' => $this->item));
  $art_publish_date = JLayoutHelper::render('joomla.content.info_block.publish_date_no_html', array('item' => $this->item));
  JRequest::setVar('cat_name', $cat_name, 'post'); //задаем глобальную переменную
  JRequest::setVar('art_publish_date', $art_publish_date, 'post'); //задаем глобальную переменную

and already in intro_image.php, add this:

$cat_name = JRequest::getVar('cat_name', '', 'post'); //считываем глобальную переменную
  $art_publish_date = JRequest::getVar('art_publish_date', '', 'post'); //считываем глобальную переменную

and already in the right place, using echo to display the name of the category and the date of publication of the material...
