As toscho stated, types_render_field()
is not a wordpress function, so you should have declared it somewhere.
HTML tags are stripped before returning the excerpt, whether you are using wp_trim_excerpt
or wp_trim_words
. If you need to keep HTML formatting in the excerpt, you will need to create your own excerpt function. To do this, you will first need to remove wp_trim_excerpt
and then add your own function.
Here is a custom excerpt that wrote a while ago. It calles as normal in template files, meaning the_excerpt()
. This excerpt keeps all HTML formatting. It also only breaks text after , ; ? .
or !
The Read more
text appear in a new paragraph, but if you need to have it next to the last word, you can just remove //
from
//$pos = strrpos($pietergoosen_excerpt, '</');
//if ($pos !== false)
// Inside last HTML tag
//$pietergoosen_excerpt = substr_replace($pietergoosen_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
Here is my excerpt
