Replace K2 RSS Image with an Extra Field Value was created by Joe Campbell

I would like to replace the cached K2 image and sized determined by the RSS Feed parameter,
with the value from Extra Field [14] for each respective item in the feed.

I found the file that I need to edit, but do not know what code to use:
/components/com_k2/models/item.php

Target Code:

$item->description .= '<div class="K2FeedImage"><img src="'.JURI::root().'media/k2/items/cache/'.md5('Image'.$item->id).'_'.$params->get('feedImgSize').'.jpg" alt="'.$altText.'" /></div>';

Desired Results:

$item->description .= '<div class="K2FeedImage"><img src="'.JURI::root().EXTRAFIELD[14].'" alt="'.$altText.'" /></div>';

A cut & paste solution would be much appreciated :)

Hello Joe,

$item->extra_fields[14]->value; might do the trick.
Let me know if that works, you might also need to enable extrafields for that view.

It did not work.

How do I enable extra fields for that view?

I am not on Twitter often so I don't really check any messages and mentions.
If I don't see you Happy New Year Joe!!

Locate:

	function prepareFeedItem(&$item)
	{

		JTable::addIncludePath(JPATH_COMPONENT_ADMINISTRATOR.DS.'tables');
		$params = K2HelperUtilities::getParams('com_k2');
		$limitstart = 0;
		$view = JRequest::getCmd('view');
		// Category
		$category = JTable::getInstance('K2Category', 'Table');
		$category->load($item->catid);
		$item->category = $category;

Add this line:

$item->extra_fields = $this->getItemExtraFields($item->extra_fields, $item);

It should look like:

	function prepareFeedItem(&$item)
	{

		JTable::addIncludePath(JPATH_COMPONENT_ADMINISTRATOR.DS.'tables');
		$params = K2HelperUtilities::getParams('com_k2');
		$limitstart = 0;
		$view = JRequest::getCmd('view');
		// Category
		$category = JTable::getInstance('K2Category', 'Table');
		$category->load($item->catid);
		$item->category = $category;
                $item->extra_fields = $this->getItemExtraFields($item->extra_fields, $item);

Not working.

Is this correct:

$item->description .= '<div class="K2FeedImage"><img src="'.JURI::root().$item->extra_fields[14]->value.'" alt="'.$altText.'" /></div>';

Where as "14" is the extra field ID

I was able to get it to work...

$item->description .= '<div class="K2FeedImage"><img src="'.JURI::root().$item->extraFields->FIELDALIAS->value.'" alt="'.$altText.'" /></div>';

Thanks @Krikor
