wordpress文章摘要的字数默认情况下是55字节

如何修改这个摘要的字数呢？

可以通过wordpress的文件

wp-includes/formatting.php

里面找到

/*** Generates an excerpt from the content, if needed.** The excerpt word amount will be 55 words and if the amount is greater than* that, then the string … will be appended to the excerpt. If the string* is less than 55 words, then the content will be returned as is.** The 55 word limit can be modified by plugins/themes using the excerpt_length filter* The … string can be modified by plugins/themes using the excerpt_more filter** @since 1.5.0** @param string $text Optional. The excerpt. If set to empty, an excerpt is generated.* @return string The excerpt.*/function wp_trim_excerpt( $text = ) {$raw_excerpt = $text;if ( == $text ) {$text = get_the_content();

$text = strip_shortcodes( $text );

/** This filter is documented in wp-includes/post-template.php */$text = apply_filters( the_content, $text );$text = str_replace(, , $text);

/*** Filter the number of words in an excerpt.** @since 2.7.0** @param int $number The number of words. Default 55.*/$excerpt_length = apply_filters( excerpt_length, 55 );/*** Filter the string in the more link displayed after a trimmed excerpt.** @since 2.9.0** @param string $more_string The string shown within the more link.*/$excerpt_more = apply_filters( excerpt_more, . … );$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );}/*** Filter the trimmed excerpt string.** @since 2.8.0** @param string $text The trimmed text.* @param string $raw_excerpt The text prior to trimming.*/return apply_filters( wp_trim_excerpt, $text, $raw_excerpt );}

其中有个55的数字，把那个数字改成你需要的摘要字数就可以了。
