O acimafuncionabem,euexecuto o código similar,mas amarre otítuloe otrechojuntos.Mas achou quebra quando alguémentraem umespaço "" ounoinício ounofinal de umtermo de consulta depesquisa.

assimive Adicionaresta linha:
$keys = array_filter($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');

Espero queisso seprojetepara ajudar os outros.

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.

As soluções acima quebrar apágina se otermo depesquisa aparecer dentro dastags HTML.Você deve usar algo como:

$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);

Adicioneestas 2funções às suasfunções.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:

Para usar o_contentpara os resultados dapesquisa,use afunção abaixo:

 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>';
    }

no seu loop oubusca.php arquivo chamada <?php search_title_highlight(); ?>em vez de <?php the_title(); ?>e use <?php search_excerpt_highlight(); ?>em vez de <?php the_excerpt(); ?>

No seu CSS,adicione a classe depesquisa depesquisa que destacarátodas aspalavraspesquisadasem amarelo.

 .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  
    }

Aplicar [``preg_quote () `] (http://php.net/preg_quote)para` $teclas 'paraimpedir que seu regexexpliqueem caso de caracteresespeciais,comoparênteses ou colchetes.

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.

Quetal destacar otermo depesquisa após o usuário clicano singlee vai dentro dopost?Em seguida,o **get_search_query () ** retorna uma string vazia

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

Aqueles devem serfiltrospara "the_excerpt"e "the_content".De qualquerforma:boa resposta,mas o comentário de @geertpoderia sertrabalhadoem :)

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