上面的代码运行得很好,我运行了类似的代码,但是将标题和摘录绑定在一起.但是发现当有人在搜索查询词的开头或结尾输入空格""时,它就会中断.

所以我添加以下行:
$keys = array_filter($keys);

// Add Bold to searched term function highlight_results($text){ if(is_search() && !is_admin()){ $sr = get_query_var('s'); $keys = explode(" ",$sr); $keys = array_filter($keys); $text = preg_replace('/('.implode('|', $keys) .')/iu', ''.$sr.'', $text); } return $text; } add_filter('the_excerpt', 'highlight_results'); add_filter('the_title', 'highlight_results');

希望这可以帮助别人.

The above works well I've run the similar code, but tie the title and excerpt together. But found it breaks when someone enters a space " " either at the beginning or end of a search query term.

So Ive add this line:
$keys = array_filter($keys);

// Add Bold to searched term function highlight_results($text){ if(is_search() && !is_admin()){ $sr = get_query_var('s'); $keys = explode(" ",$sr); $keys = array_filter($keys); $text = preg_replace('/('.implode('|', $keys) .')/iu', ''.$sr.'', $text); } return $text; } add_filter('the_excerpt', 'highlight_results'); add_filter('the_title', 'highlight_results');

Hope this proves to help others.

如果搜索词出现在HTML标记内,则上述解决方案会中断页面.您应该使用类似这样的内容:

$regEx = '\'(?!((<.*?)|(<a.*?)))(\b'. implode('|', $keys) . '\b)(?!(([^<>]*?)>)|([^>]*?</a>))\'iu'; $text = preg_replace($regEx, '\0', $text);

The above solutions break the page if the search term appears inside HTML tags. You should use something like:

$regEx = '\'(?!((<.*?)|(<a.*?)))(\b'. implode('|', $keys) . '\b)(?!(([^<>]*?)>)|([^>]*?</a>))\'iu'; $text = preg_replace($regEx, '\0', $text);

结合使用过滤器的2个答案:

// Add class to searched terms function highlight_results($text) { if (is_search() && !is_admin()) { $sr = get_query_var('s'); $keys = explode(' ', $sr); $keys = array_filter($keys); $text = preg_replace('/('.implode('|', $keys) .')/iu', '\0', $text); } return $text; } add_filter('the_excerpt', 'highlight_results'); add_filter('the_title', 'highlight_results');

然后在您的CSS中(例如):

.search-highlight { background: #ffff94; padding: 0 2px; }

Combined 2 answers to use filters :

// Add class to searched terms function highlight_results($text) { if (is_search() && !is_admin()) { $sr = get_query_var('s'); $keys = explode(' ', $sr); $keys = array_filter($keys); $text = preg_replace('/('.implode('|', $keys) .')/iu', '\0', $text); } return $text; } add_filter('the_excerpt', 'highlight_results'); add_filter('the_title', 'highlight_results');

Then in your CSS (for example) :

.search-highlight { background: #ffff94; padding: 0 2px; }

将这两个函数添加到您的functions.php

 function search_excerpt_highlight() {
    $excerpt = get_the_excerpt();
    $keys = implode('|', explode(' ', get_search_query()));
    $excerpt = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $excerpt);

    echo '<p>' . $excerpt . '</p>';
}

function search_title_highlight() {
    $title = get_the_title();
    $keys = implode('|', explode(' ', get_search_query()));
    $title = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $title);

    echo $title;
}

编辑:

要在搜索结果中使用the_content,请使用以下功能:

 function search_content_highlight() {
        $content = get_the_content();
        $keys = implode('|', explode(' ', get_search_query()));
        $content = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $content);

        echo '<p>' . $content . '</p>';
    }

在循环或search.php文件中调用<?php search_title_highlight(); ?>而不是<?php the_title(); ?>并使用<?php search_excerpt_highlight(); ?>而不是<?php the_excerpt(); ?>

在CSS中添加搜索突出显示类,该类将以黄色突出显示所有搜索到的单词.

 .search-highlight {
    background:#FFFF00  
    }

Add these 2 functions to your functions.php

function search_excerpt_highlight() {
    $excerpt = get_the_excerpt();
    $keys = implode('|', explode(' ', get_search_query()));
    $excerpt = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $excerpt);

    echo '<p>' . $excerpt . '</p>';
}

function search_title_highlight() {
    $title = get_the_title();
    $keys = implode('|', explode(' ', get_search_query()));
    $title = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $title);

    echo $title;
}

Edit:

To use the_content for your search results use the function below:

function search_content_highlight() {
        $content = get_the_content();
        $keys = implode('|', explode(' ', get_search_query()));
        $content = preg_replace('/(' . $keys .')/iu', '<strong class="search-highlight">\0</strong>', $content);

        echo '<p>' . $content . '</p>';
    }

In your loop or search.php file call <?php search_title_highlight(); ?> instead of <?php the_title(); ?> and use <?php search_excerpt_highlight(); ?> instead of <?php the_excerpt(); ?>

In your css add the search-highlight class which will highlight all searched words in yellow.

.search-highlight {
    background:#FFFF00  
    }

将[`preg_quote()`](http://php.net/preg_quote)应用于`$ keys`,以防止正则表达式因括号或方括号等特殊字符而破裂.

Apply [`preg_quote()`](http://php.net/preg_quote) to `$keys` to prevent your regex from blowing up in case of special characters like parentheses or brackets.

在用户单击单曲并进入帖子后,突出显示搜索词该怎么办?然后**get_search_query()**返回一个空字符串

What about highlighting the search term after the user clicks on the single and goes inside the post? Then the **get_search_query()** returns an empty string

这些应该是`the_excerpt`和`the_content`的过滤器.无论如何:好的答案,但是@Geert的评论可以在:)中使用.

Those should be filters for `the_excerpt` and `the_content` instead. Anyway: Nice answer, but the comment from @Geert could be worked in :)
