So in line 229 I want to define one more value (preview) like this:
[php]$content=rpf_parse_images($content,$item->get_base());
$meta = array(
‘rpf_feed_id’ => $feed[‘id’],
‘rpf_sourcepermalink’ => $link,
‘preview’ =>[/php]
I did it and its work, but the problem is that I want to insert here already existing value - from line 337 - variable [b]$real_cachepath[/b] from functio[b] rpf_cache_image[/b]. I have try to define it directly, but it dont work.
Can you help me, please
