How to limit the excerpt length by paragraph, not word/char count? For example, excerpt shows only first two paragraphs, no matter how long the paragraphs are.
Thanks in advance.
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.
if ( ! function_exists( 'wpse0001_custom_wp_trim_excerpt' ) ) :
function wpse0001_custom_wp_trim_excerpt($wpse0001_excerpt) {
global $post;
$raw_excerpt = $wpse0001_excerpt;
if ( '' == $wpse0001_excerpt ) {
$wpse0001_excerpt = get_the_content('');
$wpse0001_excerpt = strip_shortcodes( $wpse0001_excerpt );
$wpse0001_excerpt = apply_filters('the_content', $wpse0001_excerpt);
// Here we choose how many paragraphs do we want to cutthe excerpt at, This part thanks to Clément Malet
$wpse0001_excerpt = "<p>$wpse0001_excerpt</p>";
$wanted_number_of_paragraph = 2;
$tmp = explode ('</p>', $wpse0001_excerpt);
for ($i = 0; $i < $wanted_number_of_paragraph; ++$i) {
if (isset($tmp[$i]) && $tmp[$i] != '') {
$tmp_to_add[$i] = $tmp[$i];
}
}
$wpse0001_excerpt = implode('</p>', $tmp_to_add) . '</p>';
$wpse0001_excerpt = str_replace(']]>', ']]>', $wpse0001_excerpt);
$excerpt_end = ' ' . ' » ' . sprintf(__( 'Read more about: %s »', 'pietergoosen' ), get_the_title()) . '';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
//$pos = strrpos($wpse0001_excerpt, '</');
//if ($pos !== false)
// Inside last HTML tag
//$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
$wpse0001_excerpt .= $excerpt_end;
return $wpse0001_excerpt;
}
return apply_filters('wpse0001_custom_wp_trim_excerpt', $wpse0001_excerpt, $raw_excerpt);
}
endif;
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'wpse0001_custom_wp_trim_excerpt');
EDIT
Thanks to the help from #ClementMalet, I was able to tweak my function to make you choose the amount of paragraphs where you want to cut the excerpt. Please check his great answer here

I'm using the following function for an excerpt in Wordpress.
<?php
// Excerpt - end of sentence
function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ('' == $text) {
// Retrieve the post content.
$text = get_the_content('');
// Delete all shortcode tags from the content.
$text = strip_shortcodes($text);
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$allowed_tags = '<i>,<strong>';
$text = strip_tags($text, $allowed_tags);
$excerpt_word_count = 40;
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);
$excerpt_end = '...' . '<div class="read-more"><a class="button" href="' . get_permalink($post->ID) . '">' . 'Read More' . '</a></div>';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if (count($words) > $excerpt_length) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
}
else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
I want to add a second word count to use on the blog page. The above word count is being used on the front page. Advice, please? Thanks.
Try this piece of code
function custom_wp_trim_excerpt($text) {
if ( is_front_page() || is_home() ) {
// Excerpt for front page or home page
} else {
// Excerpt for rest of the site
}
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
By using this piece of code you have more control over the excerpt that is outputted on different pages.
If that worked mark your question as solved.
Here is the code for place ads after 1st, 2nd, 3d paragraph. but i want to place ad just before last paragraph of my wordpress post. is there any way to do this ?

foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {

$content = explode("</p>", $content);
$ss = count($content);
$ns = $ss-1; //**before last paragraph in wordpress **
$new_content = '';
for ($i = 0; $i < count($content); $i++) {
if ($i == $ns ) {
$new_content.= ' <div style="text-align:center;">';
$new_content.= '<h1> Your ads Here ! </h1>';
$new_content.= '</div>';
}
$new_content.= $content[$i] . "</p>";
}
return $new_content;
}

Hey guys so I ran into the same problem and managed to solve it incorporating your answers into one.
The function that does all the processing is changed so that is counts all the paragraphs created by the explode method. Then another if statement is added to evaluate when you are at the desired location.
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
$last_paragraph_index = count($paragraphs);
foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}
if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
else if( $last_paragraph_index + $paragraph_id == $index + 1){
$paragraphs[$index] .= $insertion;
}
}
return implode( '', $paragraphs );
}
in order to use the new functionality you must call it with a negative number.
Think of the function this way, if you want to go from the top of the content you use a positive number, if you want to go from the bottom of the content you use a negative number.
Remember that even though the evaluation is for your decided spot such as before the last paragraph the condition that adds to the array uses the index which we all know is zero based.
This just means that to get after paragraph 1 you must use the number 2 when calling the function and to get to before the last paragraph you have to use -2 and so on.
Here is my example to add the a read the next post if it exists to the article
add_filter( 'the_content', 'prefix_insert_next_article_banner' );
function prefix_insert_next_article_banner( $content ) {
if ( is_single() && ! is_admin() && get_next_post_link() ) {
$next_banner = '<div class="next-banner"> <span> Read Next </span>';
$next_banner .= ' ' . get_the_title(get_adjacent_post(false,'',false)) .' ';
$next_banner .= '</div>';
return prefix_insert_after_paragraph( $next_banner, -2, $content );
}
return $content;
}
I'm using wp_link_pages() to split my post into multiple pages. I want to achieve something like this as shown in the image below. Instead of showing all the page numbers with links, I want it to show only this format (Current Page of Total Page). Please help me with the exact codes. Thank you so much in advance.
PS: I don't want to use plugins.
There is a simple solution to this problem. I've got this inspiration from source file where function wp_link_pages is defined.
function page_pagination( $echo = 1 )
{
global $page, $numpages, $multipage, $more;
if( $multipage ) { //probably you should add && $more to this condition.
$next_text = "next";
$prev_text = "prev";
if( $page < $numpages ) {
$next = _wp_link_page( $i = $page + 1 );
$next_link = $next . $next_text . "</a>";
}
if( $i = ( $page - 1 ) ) {
$prev = _wp_link_page( $i );
$prev_link = $prev . $prev_text . "</a>";
}
$output =
"<div class=\"prev-next-page\">"
. $prev_link
. "<span class=\"page-counter\">{$page} of {$numpages}</span>"
. $next_link
. "</div>";
}
if( $echo ){
echo $output;
}
return $output;
}
If you need more freedom you can always adapt this function to suit your purposes. Include function into wordpress loop! Like this for example:
if ( have_posts( ) ) {
while ( have_posts( ) ) {
the_post( );
//rest of code
the_content();
page_pagination();
}
}
As you can see, there is "private" function _wp_link_page used to solve your problem. I don't like using "private" functions, but it solves our problem.
I am struggling with this one for half a day now and i can't seem to get it right. I have a custom function in my wordpress site, that automatically creates an excerpt. This all goes well, but for some (i guess logical) reason it also cuts off the <br /> tag, since it has a space.
How to fix this? This has to do with the preg_split function right?
Below is my code:
function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ( '' == $text ) {
//Retrieve the post content.
$text = get_the_content('');
//Delete all shortcode tags from the content.
$text = strip_shortcodes( $text );
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$allowed_tags = '<p>,<br>,<br/>,<br />,<a>,<em>,<strong>,<img>'; /*** MODIFY THIS. Add the allowed HTML tags separated by a comma.***/
$text = strip_tags($text, $allowed_tags);
$excerpt_word_count = 40; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);
$excerpt_end = ' ' . '...' . '';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if ( count($words) > $excerpt_length && $words ) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
} else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
Thanks!
You can add this to make all of the HTML break characters the same:
$text = preg_replace('!<br ?/>!i','<br>',$text);
Before these lines:
$allowed_tags = '<p>,<br>,<a>,<em>,<strong>,<img>'; /*** MODIFY THIS. Add the allowed HTML tags separated by a comma.***/
$text = strip_tags($text, $allowed_tags);
When you're doing preg_split("/[\n\r\t ]+/",$text) you're splitting the space in the break <br /> character.
You can also simplify the regex in the preg_split() statement:
$words = preg_split("!\s+!", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
Since you're allowing the other tags they probably contain spaces too though.
the code looks like this
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
there is an option in wp-admin>settings>reading>For each article in a feed, show
if this is set to full text
the excerpt() must return full length article instead of specified length.
how to do this?
Good question! The answer is simple: write your own function!
Open up functions.php in your favorite editor and mash random buttons on your keyboard until you get something like this:
function my_awesome_excerpt ($post_id = false, $full = false, $length = 22) {
if (!$post_id) global $post;
else $post = get_post($post_id);
$text = $post->post_content;
if ($full) return $text;
else {
$text_array = explode(' ', $text);
$return_string = array();
for ($i = 0; $i <= $length; $i++)
array_push($return_string, $text_array[$i]);
$new_awesome_string = '<p>';
$new_awesome_string .= implode(' ', $return_string);
$new_awesome_string .= '</p><p class="readmore">';
$new_awesome_string .= '<a href="' . get_permalink($post_id) . '">';
$new_awesome_string .= 'Read More' . '</a></p>';
return $new_awesome_string;
}
}
Now, you're ready for the cool part. Once you're in your loop, you can write out some magic like this:
echo my_awesome_excerpt();
and it will automagically spit out an excerpt. It's using the global post variable and everything! You can even use it outside of the loop:
echo my_awesome_excerpt($cpt->ID, 22);
and set your own special length!
Or maybe you just know in your heart that it's not worth it, you just want to show the whole thing. How's that look?
Inside the loop, you're going to have to give it a post ID, sorry about that.
echo my_awesome_script($post->ID, false);
I hope this helps. Have a great day!
