I have a WordPress installation that sometimes uses long and lengthy posts delimited by the <!--more--> tag. However on my RSS feeds, the entire post is shown.
Is there a way, aside from custom tags, to delimit how much is shown in a WordPress Feed or just show enough until the "More" tag?
You can select between Full text and Summary in the Reading settings:
If you select the Summary, then
a) To control the number of words in the feed summary you can use:
add_filter('excerpt_length','custom_excerpt_length'); function custom_excerpt_length( $num_words ){ return 30; // number of words to show } The default number of words in the summary is 55.
b) If you want to use <!--more--> in the post content to define the feed summary, you can use the following:
add_filter( 'the_content', 'custom_content_feed' ); function custom_content_feed( $content ){ if( is_feed() ){ // <!--more--> used in the post content: if( strpos( $content, '<span id="more-') !== FALSE ){ // remove the excerpt length limit add_filter( 'excerpt_length', 'custom_long_excerpt_length' ); // get the content before <!--more--> $content = stristr( $content, '<span id="more-', TRUE ); // add the default 'read more' symbols at the end: $excerpt_more = apply_filters( 'excerpt_more', ' ' . '[…]' ); $content .= $excerpt_more; } } return $content; } function custom_long_excerpt_length( $num_words ){ return 99999; } c) You can also use a) and b) together.
