Das obigefunktioniertgut Ich habe den ähnlichen Code ausgeführt,aber den Titel und den Auszug zusammengebunden.Es wurdejedochfestgestellt,dasses unterbrochen wird,wennjemandein Leerzeichen ""entweder am Anfang oder am Endeeines Suchabfragebegriffsbetritt.

Alsofügeich diese Zeile hinzu:
$keys = array_filter($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');

Ich hoffe,dies hilft anderen.

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.

Die obengenannten Lösungen unterbrechen die Seite,wenn der Suchbegriffin HTML-Tags angezeigt wird.Sie solltenetwas verwenden wie:

$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);

Fügen Sie diesebeiden Funktionen zu Ihrerfunctions.php

hinzu

 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;
}

Bearbeiten:

Um den Inhaltfür Ihre Suchergebnisse zu verwenden,verwenden Sie diefolgende Funktion:

 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>';
    }

Rufen Siein Ihrer Schleife oderin der Datei search.php <?php search_title_highlight(); ?> anstelle von <?php the_title(); ?> und verwenden Sie <?php search_excerpt_highlight(); ?> anstelle von <?php the_excerpt(); ?>

Fügen Siein Ihrem CSS die Such-Hervorhebungsklasse hinzu,die allegesuchten Wörtergelb hervorhebt.

 .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  
    }

Wenden Sie [`preg_quote ()`] (http://php.net/preg_quote) auf `$ keys` an,um zu verhindern,dass Ihre Regexbei Sonderzeichen wie Klammern oder Klammernexplodiert.

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.

Wasistmit dem Hervorheben des Suchbegriffs,nachdem der Benutzer auf die Singlegeklickt hat undin den Beitraggelangtist?Danngibt die **get_search_query () **eine leere Zeichenfolge zurück

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

Dies sollten stattdessen Filterfür "the_excerpt" und "the_content" sein.Wie auchimmer: Schöne Antwort,aber der Kommentar von @Geert könntebearbeitet werden :)

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