今天有朋友问了一个问题,如何移除归档页面分类或标签名称前面的“分类:”和“标签:”,如下图:
首先,我们要先了解这两个字是通过什么函数调用出来的,在比较正规的主题中,一般会用以下代码在归档页面输入标题:
1 | <?php the_archive_title( '<h1 class="page-title">', '</h1>' ); ?> |
<?php the_archive_title( '<h1 class="page-title">', '</h1>' ); ?>
而这个the_archive_title() 函数的代码为:
1 2 3 4 5 6 7 | function the_archive_title( $before = '', $after = '' ) { $title = get_the_archive_title(); if ( ! empty( $title ) ) { echo $before . $title . $after; } } |
function the_archive_title( $before = '', $after = '' ) { $title = get_the_archive_title(); if ( ! empty( $title ) ) { echo $before . $title . $after; } }
可以看到,调用的是get_the_archive_title() 的内容,我们再来看看这个get_the_archive_title() 的代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 | function get_the_archive_title() { if ( is_category() ) { /* translators: Category archive title. %s: Category name */ $title = sprintf( __( 'Category: %s' ), single_cat_title( '', false ) ); } elseif ( is_tag() ) { /* translators: Tag archive title. %s: Tag name */ $title = sprintf( __( 'Tag: %s' ), single_tag_title( '', false ) ); } elseif ( is_author() ) { /* translators: Author archive title. %s: Author name */ $title = sprintf( __( 'Author: %s' ), '<span class="vcard">' . get_the_author() . '</span>' ); } elseif ( is_year() ) { /* translators: Yearly archive title. %s: Year */ $title = sprintf( __( 'Year: %s' ), get_the_date( _x( 'Y', 'yearly archives date format' ) ) ); } elseif ( is_month() ) { /* translators: Monthly archive title. %s: Month name and year */ $title = sprintf( __( 'Month: %s' ), get_the_date( _x( 'F Y', 'monthly archives date format' ) ) ); } elseif ( is_day() ) { /* translators: Daily archive title. %s: Date */ $title = sprintf( __( 'Day: %s' ), get_the_date( _x( 'F j, Y', 'daily archives date format' ) ) ); } elseif ( is_tax( 'post_format' ) ) { if ( is_tax( 'post_format', 'post-format-aside' ) ) { $title = _x( 'Asides', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-gallery' ) ) { $title = _x( 'Galleries', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-image' ) ) { $title = _x( 'Images', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-video' ) ) { $title = _x( 'Videos', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-quote' ) ) { $title = _x( 'Quotes', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-link' ) ) { $title = _x( 'Links', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-status' ) ) { $title = _x( 'Statuses', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-audio' ) ) { $title = _x( 'Audio', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-chat' ) ) { $title = _x( 'Chats', 'post format archive title' ); } } elseif ( is_post_type_archive() ) { /* translators: Post type archive title. %s: Post type name */ $title = sprintf( __( 'Archives: %s' ), post_type_archive_title( '', false ) ); } elseif ( is_tax() ) { $tax = get_taxonomy( get_queried_object()->taxonomy ); /* translators: Taxonomy term archive title. 1: Taxonomy singular name, 2: Current taxonomy term */ $title = sprintf( __( '%1$s: %2$s' ), $tax->labels->singular_name, single_term_title( '', false ) ); } else { $title = __( 'Archives' ); } /** * Filters the archive title. * * @since 4.1.0 * * @param string $title Archive title to be displayed. */ return apply_filters( 'get_the_archive_title', $title ); } |
function get_the_archive_title() { if ( is_category() ) { /* translators: Category archive title. %s: Category name */ $title = sprintf( __( 'Category: %s' ), single_cat_title( '', false ) ); } elseif ( is_tag() ) { /* translators: Tag archive title. %s: Tag name */ $title = sprintf( __( 'Tag: %s' ), single_tag_title( '', false ) ); } elseif ( is_author() ) { /* translators: Author archive title. %s: Author name */ $title = sprintf( __( 'Author: %s' ), '<span class="vcard">' . get_the_author() . '</span>' ); } elseif ( is_year() ) { /* translators: Yearly archive title. %s: Year */ $title = sprintf( __( 'Year: %s' ), get_the_date( _x( 'Y', 'yearly archives date format' ) ) ); } elseif ( is_month() ) { /* translators: Monthly archive title. %s: Month name and year */ $title = sprintf( __( 'Month: %s' ), get_the_date( _x( 'F Y', 'monthly archives date format' ) ) ); } elseif ( is_day() ) { /* translators: Daily archive title. %s: Date */ $title = sprintf( __( 'Day: %s' ), get_the_date( _x( 'F j, Y', 'daily archives date format' ) ) ); } elseif ( is_tax( 'post_format' ) ) { if ( is_tax( 'post_format', 'post-format-aside' ) ) { $title = _x( 'Asides', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-gallery' ) ) { $title = _x( 'Galleries', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-image' ) ) { $title = _x( 'Images', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-video' ) ) { $title = _x( 'Videos', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-quote' ) ) { $title = _x( 'Quotes', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-link' ) ) { $title = _x( 'Links', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-status' ) ) { $title = _x( 'Statuses', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-audio' ) ) { $title = _x( 'Audio', 'post format archive title' ); } elseif ( is_tax( 'post_format', 'post-format-chat' ) ) { $title = _x( 'Chats', 'post format archive title' ); } } elseif ( is_post_type_archive() ) { /* translators: Post type archive title. %s: Post type name */ $title = sprintf( __( 'Archives: %s' ), post_type_archive_title( '', false ) ); } elseif ( is_tax() ) { $tax = get_taxonomy( get_queried_object()->taxonomy ); /* translators: Taxonomy term archive title. 1: Taxonomy singular name, 2: Current taxonomy term */ $title = sprintf( __( '%1$s: %2$s' ), $tax->labels->singular_name, single_term_title( '', false ) ); } else { $title = __( 'Archives' ); } /** * Filters the archive title. * * @since 4.1.0 * * @param string $title Archive title to be displayed. */ return apply_filters( 'get_the_archive_title', $title ); }
好长一段代码,注意看倒数第二行代码为:
1 | return apply_filters( 'get_the_archive_title', $title ); |
return apply_filters( 'get_the_archive_title', $title );
此处应用了一个过滤钩子,也就是我们可以通过这个钩子修改get_the_archive_title() 的内容,从而实现修改the_archive_title() 输出的内容。
要实现刚才我们说的去掉归档页面的“分类:”和“标签:”,可以使用下面的代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | function my_theme_archive_title( $title ) { if ( is_category() ) { $title = single_cat_title( '', false ); } elseif ( is_tag() ) { $title = single_tag_title( '', false ); } elseif ( is_author() ) { $title = '<span class="vcard">' . get_the_author() . '</span>'; } elseif ( is_post_type_archive() ) { $title = post_type_archive_title( '', false ); } elseif ( is_tax() ) { $title = single_term_title( '', false ); } return $title; } add_filter( 'get_the_archive_title', 'my_theme_archive_title' ); |
function my_theme_archive_title( $title ) { if ( is_category() ) { $title = single_cat_title( '', false ); } elseif ( is_tag() ) { $title = single_tag_title( '', false ); } elseif ( is_author() ) { $title = "<span class="vcard">" . get_the_author() . '</span>'; } elseif ( is_post_type_archive() ) { $title = post_type_archive_title( '', false ); } elseif ( is_tax() ) { $title = single_term_title( '', false ); } return $title; } add_filter( 'get_the_archive_title', 'my_theme_archive_title' );
将该代码添加到当前使用的主题的 functions.php 文件即可。
本文WordPress 移除归档页面的“分类:”,即自定义the_archive_title输出到此结束。如果说青春也有缺点,那就是它消失得太快。小编再次感谢大家对我们的支持!
