所讨论的文本来源于wp-includes/widgets/class-wp-widget-recent-comments.php
我通过在WP文件中搜索小部件的id找到了它，recentcomments, 这是我通过检查小部件的HTML收集的。因此，这里是关于的内容的来源，还有一些额外的上下文代码：
foreach ( (array) $comments as $comment ) {
$output .= \'<li class="recentcomments">\';
/* translators: comments widget: 1: comment author, 2: post link */
$output .= sprintf( _x( \'%1$s on %2$s\', \'widgets\' ),
\'<span class="comment-author-link">\' . get_comment_author_link( $comment ) . \'</span>\',
\'<a href="\' . esc_url( get_comment_link( $comment ) ) . \'">\' . get_the_title( $comment->comment_post_ID ) . \'</a>\'
);
$output .= \'</li>\';
}
在这里我们可以看到
$output .= sprintf( _x( \'%1$s on %2$s\', \'widgets\' ), 是我们需要换的绳子。我们可以使用
gettext_with_context 筛选以一次性删除作者和单词。
/**
* @param string $translated
* @param string $text
* @param string $context
* @param string $domain
* @return string
*/
function wpse238430_recent_comments_text( $translated, $text, $context, $domain ) {
// Use guard clauses to bail as soon as possible if we\'re not looking
// at the things we want. Bailing early is a good practice because
// translation filters are called frequently, so code in this function could be run many times, causing an impact on performance.
// Our string identified above used the \'widgets\' context, so make sure that\'s what we\'re looking at.
if ( $context !== \'widgets\' ) {
return $translated;
}
// WordPress uses the \'default\' text domain, even though one is not explicitly specified. Bail if the text domain is not \'default\';
if ( \'default\' !== $domain ) {
return $translated;
}
// $text contains the string to be evaluated for translation.
switch ( $text ) {
case \'%1$s on %2$s\' : // If $text == \'%1$s on %2$s\', do something..
//$translated = \'%1$s on %2$s\'; // original string. %1$s is the comment author and %2$s is the post they commented on
$translated = \'%2$s\'; // Remove the author and \'on\'
break;
}
// Return our modified string. Now the original `sprintf()` function will simply output the link to the post that the author commented on.
return $translated;
}
add_filter( \'gettext_with_context\', \'wpse238430_recent_comments_text\', 20, 4 );
