Joomla 3.4 override com_content/default_articles.php with blog_item

Question

i'm working on the category overrides (com_content/category/) right now and trying to display the items of each category directly under its category

like this:

maincat (com_content/category/default_articles.php)

-cat 1 (com_content/category/default_children)

-- undercat1 1 (com_content/category/blog_item.php)

-- undercat1 2

so i need to insert code from blog_item.php into default_articles or default_children

this

<div class="test"> 
  <?php echo $this->item->event->beforeDisplayContent; ?>
   <?php echo $this->item->introtext; ?>  
</div>

needs to go into default_articles but i get a property error, also tried to use different variable names - same error. Error:

Notice: Undefined property: stdClass::$event in D:\\xampp\\htdocs\\joomla\\templates\\protostar\\html\\com_content\\category\\default_children.php on line 66

Notice: Trying to get property of non-object in D:\\xampp\\htdocs\\joomla\\templates\\protostar\\html\\com_content\\category\\default_children.php on line 66

Notice: Undefined property: stdClass::$introtext in D:\\xampp\\htdocs\\joomla\\templates\\protostar\\html\\com_content\\category\\default_children.php on line 66

Line 66 from default_children.php:

<?php echo $this->item->event->beforeDisplayContent; ?> <?php echo $this->item->introtext; ?>

(this line is originally from com_content/category/blog_item.php, i want it to be in default_children.php)

default_children.php

I'm not yet that good with PHP - probably some of you could give me a hint towards a solution?

thank you

Answer 1

I'm not sure exactly what you are trying to do but I think you are confused about that the default_children template is doing. It is not displaying articles, it is displaying information on any child categories of the category that is defining the blog. Hence in the code you posted you don't see any reference to $item you see references to $child . Categories do not have introtext they have description and thus you see $child->description .

The file you want to override is default_articles . If you look in there you will see references to $article->created_by_alias so that tells you probably you want $article->introtext .
