A few excerpts in wordpress

Question

As the title says, I'm looking for a few excerpts in WordPress.

I understand that you can do this in functions.php:

function twentyten_excerpt_length( $length ) { return 15; } add_filter( 'excerpt_length', 'twentyten_excerpt_length' ); 

What I want to know is how you can have several of them, each of which returns different numerical values, so I can get short excerpts for sidebar loops, longer excerpts for selected loops and the longest excerpt for the main article.

Something like using these patterns:

 <?php the_excerpt('length-short') ?> <?php the_excerpt('length-medium') ?> <?php the_excerpt('length-long') ?> 

Cheers, dave

What about...

 function excerpt($limit) { $excerpt = explode(' ', get_the_excerpt(), $limit); if (count($excerpt) >= $limit) { array_pop($excerpt); $excerpt = implode(" ", $excerpt) . '...'; } else { $excerpt = implode(" ", $excerpt); } $excerpt = preg_replace('`\[[^\]]*\]`', '', $excerpt); return $excerpt; } function content($limit) { $content = explode(' ', get_the_content(), $limit); if (count($content) >= $limit) { array_pop($content); $content = implode(" ", $content) . '...'; } else { $content = implode(" ", $content); } $content = preg_replace('/\[.+\]/','', $content); $content = apply_filters('the_content', $content); $content = str_replace(']]>', ']]>', $content); return $content; } 

then in the code of your template you just use.

 <?php echo excerpt(25); ?>

Now you can update Marty's answer:

 function excerpt($limit) { return wp_trim_words(get_the_excerpt(), $limit); } 

You can also set up a custom read more link:

 function custom_read_more() { return '... <a class="read-more" href="'.get_permalink(get_the_ID()).'">more&nbsp;&raquo;</a>'; } function excerpt($limit) { return wp_trim_words(get_the_excerpt(), $limit, custom_read_more()); } 

Answer 3

Here is what I came up with.

Add this to your functions.php

 class Excerpt { // Default length (by WordPress) public static $length = 55; // So you can call: my_excerpt('short'); public static $types = array( 'short' => 25, 'regular' => 55, 'long' => 100 ); /** * Sets the length for the excerpt, * then it adds the WP filter * And automatically calls the_excerpt(); * * @param string $new_length * @return void * @author Baylor Rae' */ public static function length($new_length = 55) { Excerpt::$length = $new_length; add_filter('excerpt_length', 'Excerpt::new_length'); Excerpt::output(); } // Tells WP the new length public static function new_length() { if( isset(Excerpt::$types[Excerpt::$length]) ) return Excerpt::$types[Excerpt::$length]; else return Excerpt::$length; } // Echoes out the excerpt public static function output() { the_excerpt(); } } // An alias to the class function my_excerpt($length = 55) { Excerpt::length($length); } 

It can be used as follows.

 my_excerpt('short'); // calls the defined short excerpt length my_excerpt(40); // 40 chars 

This is the easiest way to add filters that can be called from a single function.

Answer 4

I also searched for this feature, and most of the features here are nice and flexible. For my case, I was looking for a solution that shows a different fragment length only on certain pages. I use this:

 function custom_excerpt_length( $length ) { return (is_front_page()) ? 15 : 25; } add_filter( 'excerpt_length', 'custom_excerpt_length', 999 ); 

Paste this code into the functions.php theme file.

Answer 5

Returning to Marty's answer:

I know that more than a year has passed since this answer was published, but better late than never. To work with the default limitations of WordPress 55, you need to replace this line:

  $excerpt = explode(' ', get_the_excerpt(), $limit); 

with this line:

  $excerpt = explode(' ', get_the_content(), $limit); 

Otherwise, the function only works with the already trimmed piece of text.

Answer 6

I think now we can use wp_trim_words here . I'm not sure what additional screening and disinfection features are needed to use this feature, but it looks interesting.

Answer 7

You can add this function to your functions.php file.

 function custom_length_excerpt($word_count_limit) { $content = wp_strip_all_tags(get_the_content() , true ); echo wp_trim_words($content, $word_count_limit); } 

Then name it in your template as follows

 <p><?php custom_length_excerpt(50); ?> 

wp_strip_all_tags should prevent html shadow tags from breaking.

Answer 8

Here's an easy way to limit content or exposure.

 $content = get_the_excerpt(); $content = strip_tags($content); echo substr($content, 0, 255); 

change get_the_excerpt () to get_the_content () if you want the content.

Answer 9

I found a great plugin that can do this - Content and Excerpt Word Limit

Answer 10

Use extended snippet
http://wordpress.org/extend/plugins/advanced-excerpt/ plugin. I also found the answer from this page.

Answer 11

I can create a short code, I have not tried it, but I wrote the basic idea for you about its structure

 function twentyten_excerpt_length($atts,$length=null){ shortcode_atts(array('exlength'=>'short'),$atts); if(!isset($atts['exlength']) || $atts['exlength'] == 'short') { return 15; }elseif( $atts['exlength'] == 'medium' ){ return 30; // or any value you like }elseif( $atts['exlength'] == 'long' ){ return 45; // or any value you like }else{ // return nothing } } add_shortcode('the_excerpt_sc','twentyten_excerpt_length'); 

so you can use it like that

 [the_excerpt_sc exlength="medium"] 

Answer 12

I know this is a really old thread, but I just struggled with this problem and none of the solutions I found on the Internet worked correctly for me. First, my own excerpt_more filter has always been cut off.

The way I decided is ugly, but this is the only working solution I could find. The ugliness involves modifying the 4 lines of the WP kernel (!!) + using another global variable (although WP already does this so that I don't feel too bad).

I changed wp_trim_excerpt to wp-includes / formatting.php:

 <?php function wp_trim_excerpt($text = '') { global $excerpt_length; $len = $excerpt_length > 0 ? $excerpt_length : 55; $raw_excerpt = $text; if ( '' == $text ) { $text = get_the_content(''); $text = strip_shortcodes( $text ); $text = apply_filters('the_content', $text); $text = str_replace(']]>', ']]&gt;', $text); $excerpt_length = apply_filters('excerpt_length', $len); $excerpt_more = apply_filters('excerpt_more', ' ' . '[&hellip;]'); $text = wp_trim_words( $text, $excerpt_length, $excerpt_more ); } $excerpt_length = null; return apply_filters('wp_trim_excerpt', $text, $raw_excerpt); } 

The only new material is the $excerpt_length and $len bits.

Now, if I want to change the default length, I do this in my template:

 <?php $excerpt_length = 10; the_excerpt() ?> 

Changing the kernel is a terrible decision, so I would like to know if someone comes up with something better.

Answer 13

Be careful using some of these methods. Not all of them supplant html tags, that is, if someone inserts a link to a video (or url) in the first sentence of his message, the video (or link) will be displayed in an excerpt, possibly inflating your page.

Answer 14

I would do the following:

 function _get_excerpt($limit = 100) { return has_excerpt() ? get_the_excerpt() : wp_trim_words(strip_shortcodes(get_the_content()),$limit); } 

Using:

 echo _get_excerpt(30); // Inside the loop / query 

Why?

• If has_excerpt should return a given passage
• It is not, therefore, truncate words / shorten the_content from the_content

Answer 15

Here 's an article about using custom shutter speeds in WordPres. There are several ways to limit and shutter speed for control messages.

• Limit tear-off length or message length using word count.
• Limit shutter speed to a few characters.
• Limit post message by adding 'read more tag.
• Include custom excerpts for writing your own resume for each post.
• Filter expression control length
