here<\/a>. Here is function, add any html tags to this that you need to allow\/keep<\/p>\nfunction wpse_allowedtags() {\n\/\/ Add custom tags to this string\n return '<script>,<style>,<br>,<em>,<i>,<ul>,<ol>,<li>,<a>,<p>,<img>,<video>,<audio>'; \n}\n<\/code><\/pre>\nIf you need to allow all HTML tags, that is, no stripping of any tags, the strips_tags()<\/code> function can be omitted\/removed completely.<\/p>\nA point to note however, when html tags are allowed, these tags are counted as words, so your word count for excerpts with tags and without tags will not be the same. To correct that, you will need to remove these tags from the actual word count first so that only words are counted.<\/p>\n
I have written an excerpt that will allow all tags, count only words as words, and complete a sentence after the set amount of words (so the text won’t be trimmed mid-sentence) and add a read more text after the last word.<\/p>\n
Here is the complete code<\/p>\n
function wpse_allowedtags()\n{\n \/\/ Add custom tags to this string\n return '<script>,<style>,<br>,<em>,<i>,<ul>,<ol>,<li>,<a>,<p>,<img>,<video>,<audio>';\n}\n\nif (!function_exists('wpse_custom_wp_trim_excerpt')) :\n\n function wpse_custom_wp_trim_excerpt($wpse_excerpt)\n {\n $raw_excerpt = $wpse_excerpt;\n if ('' == $wpse_excerpt) {\n\n $wpse_excerpt = get_the_content('');\n $wpse_excerpt = strip_shortcodes($wpse_excerpt);\n $wpse_excerpt = apply_filters('the_content', $wpse_excerpt);\n $wpse_excerpt = str_replace(']]>', ']]>', $wpse_excerpt);\n $wpse_excerpt = strip_tags($wpse_excerpt, wpse_allowedtags()); \/*IF you need to allow just certain tags. Delete if all tags are allowed *\/\n\n \/\/Set the excerpt word count and only break after sentence is complete.\n $excerpt_word_count = 75;\n $excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);\n $tokens = array();\n $excerptOutput=\"\";\n $count = 0;\n\n \/\/ Divide the string into tokens; HTML tags, or words, followed by any whitespace\n preg_match_all('\/(<[^>]+>|[^<>\\s]+)\\s*\/u', $wpse_excerpt, $tokens);\n\n foreach ($tokens[0] as $token) {\n\n if ($count >= $excerpt_length && preg_match('\/[\\,\\;\\?\\.\\!]\\s*$\/uS', $token)) {\n \/\/ Limit reached, continue until , ; ? . or ! occur at the end\n $excerptOutput .= trim($token);\n break;\n }\n\n \/\/ Add words to complete sentence\n $count++;\n\n \/\/ Append what's left of the token\n $excerptOutput .= $token;\n }\n\n $wpse_excerpt = trim(force_balance_tags($excerptOutput));\n\n $excerpt_end = ' <a href=\"' . esc_url(get_permalink()) .

CUSTOM EXCERPT LENGTHS<\/strong><\/p>\nSometimes you need to display simple excerpts of different lengths and it is not viable to write an excerpt for every post\/function\/page. Here is a nice small little function using wp_trim_words<\/code><\/p>\nfunction wpse_custom_excerpts($limit) {\n return wp_trim_words(get_the_excerpt(), $limit, '<a href=\"'. esc_url( get_permalink() ) . '\">' . ' …' . __( 'Read more »', 'wpse' ) . '<\/a>');\n}\n<\/code><\/pre>\nWhat this little function does is taking get_the_excerpt<\/code>, trimming it to $limit<\/code> set by the user, and returning the text with a read more link at the end.<\/p>\nYou can call this excerpt as follow in your template<\/p>\n
echo wpse_custom_excerpts($limit);\n<\/code><\/pre>\nwhere $limit<\/code> will be your word count, so an excerpt of 30 words will be<\/p>\necho wpse_custom_excerpts(30);\n<\/code><\/pre>\nJust one thing to remember here, if you set your limit to more that 55 words, only 55 words will be returned as the excerpt is only 55 words in length. If longer excerpts are needed, use get_the_content<\/code> instead.<\/p>\nCUSTOM EXCERPT LENGTH<\/strong><\/p>\nIf you just need to alter the length of the_excerpt()<\/code>, you can use the following function<\/p>\nfunction wpse_excerpt_length( $length ) {\n return 20;\n}\nadd_filter( 'excerpt_length', 'wpse_excerpt_length', 999 );\n<\/code><\/pre>\nRemember, you will need to set a priority bigger than 10 so that your custom function executes after the default.<\/p>\n
ADD READ MORE LINK<\/strong><\/p>\nAll text returned by the excerpt have the hated [...]<\/code> at the end that is not clickable. To add a read more text in the place of the hellips, use this function<\/p>\n function wpse_excerpt_more( $more ) {\n return ' <a class=\"read-more\" href=\"'. get_permalink( get_the_ID() ) . '\">' . __('Read More', 'your-text-domain') . '<\/a>';\n}\nadd_filter( 'excerpt_more', 'wpse_excerpt_more' );\n<\/code><\/pre>\nEDIT<\/strong><\/p>\nExcerpt first paragraph<\/strong><\/p>\nI want to keep this complete, so here is the excerpt that trims after the first paragraph.<\/p>\n
Here is a function that keeps HTML tags in tact, adds a “Read More” link at the end of the excerpt and trims the excerpt after the first paragraph.<\/p>\n
if ( ! function_exists( 'wpse0001_custom_wp_trim_excerpt' ) ) : \n \n function wpse0001_custom_wp_trim_excerpt($wpse0001_excerpt) {\n global $post;\n $raw_excerpt = $wpse0001_excerpt;\n if ( '' == $wpse0001_excerpt ) {\n \n $wpse0001_excerpt = get_the_content('');\n $wpse0001_excerpt = strip_shortcodes( $wpse0001_excerpt );\n $wpse0001_excerpt = apply_filters('the_content', $wpse0001_excerpt);\n $wpse0001_excerpt = substr( $wpse0001_excerpt, 0, strpos( $wpse0001_excerpt, '<\/p>' ) + 4 );\n $wpse0001_excerpt = str_replace(']]>', ']]>', $wpse0001_excerpt);\n \n $excerpt_end = ' <a href=\"'. esc_url( get_permalink() ) . '\">' . ' » ' . sprintf(__( 'Read more about: %s »', 'pietergoosen' ), get_the_title()) . '<\/a>'; \n $excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end); \n \n \/\/$pos = strrpos($wpse0001_excerpt, '<\/');\n \/\/if ($pos !== false)\n \/\/ Inside last HTML tag\n \/\/$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);\n \/\/else\n \/\/ After the content\n $wpse0001_excerpt .= $excerpt_more;\n \n return $wpse0001_excerpt;\n \n }\n return apply_filters('wpse0001_custom_wp_trim_excerpt', $wpse0001_excerpt, $raw_excerpt);\n }\n \nendif; \n \nremove_filter('get_the_excerpt', 'wp_trim_excerpt');\nadd_filter('get_the_excerpt', 'wpse0001_custom_wp_trim_excerpt');\n<\/code><\/pre>\nEDIT 29-10-2015<\/h2>\n
