Выделение поисковых запросов

Описание

Highlights search terms within WordPress generated search results, both on the search results page and on each linked post page itself.

This plugin is light weight and has no options. It started as very simple fusion between How to Highlight Search Terms with jQuery — theme hack by Thaya Kareeson and Search Hilite by Ryan Boren. It has since evolved with many optimizations, HTML5 and bbPress support.

Начиная с версии 1.6 он больше не зависит от библиотеки jQuery.

Функции

  • Выделение по щелчку: выделение не только на странице результатов поиска WP, но и на один клик глубже на любой из найденных страниц.
  • Character and case insensitive (lenient) highlighting
  • Совместимость с BuddyPress / bbPress: выделение при поиске по форуму
  • Совместимость с кэшированием (WP Super Cache)
  • Search terms wrapped in double quotes now considered as single term

Что оно делает?

This low impact plugin finds all search terms on a search results page inside each post and highlights them with a <mark class="hilite term-N"> ... </mark> tag.
Note that N is a number starting with 0 for the first term used in the search phrase increasing 1 for each additional term used. Any part of a search phrase wrapped in quotes is considered as a single term.

Что НЕ делает?

There are no CSS style rules set for highlighting. You are free to use any styling you wish but to make the highlights visible in browsers that do not support HTML5 like Internet Explorer 8 or older you absolutely need to define at least one rule.
Modern HTML5 browsers will use their own highlighting style by default, which usually is a yellow marker style background.

Итак, что мне нужно сделать?

В большинстве случаев он должен просто работать. Но вы можете сделать две вещи, чтобы обеспечить обратную совместимость с браузером и темой:

  1. Define CSS rules: There are no configuration options and there is no predefined highlight styling. You are completely free to define any CSS styling rules in your themes main stylesheet (style.css) or the Custom CSS tab if the WordPress theme customizer.
    You can find basic instructions and CSS examples in the FAQ’s.

  2. Check your theme: In most up to date themes (including WP’s own default theme) post and page content is shown inside a div with class hentry. This means search terms found in post and page content will be highlighted but not similar terms that accidentally show in the page header, sidebar or footer.
    If your current theme does not use the hentry class (yet), this plugin will look for IDs content, main and finally wrapper but if none of those are found, it will not work for you out of the box. See the last of the FAQ’s for ways to make it work.

Доступные хуки и фильтры

  1. hlst_query_vars — Массив переменных запроса WordPress, которые плагин идентифицирует как поисковый запрос. Должен возвращать массив. Дефолт: ['search_terms','bbp_search'] (WordPress и bbPress поиск)

  2. hlst_input_get_args — An array of GET variables that the plugin will identify as a search query. Must return an array. Default: ['hilite'] (for click-through highlighting)

  3. hlst_selectors — The array of possible HTML DOM element identifiers that the script will try. The first viable identifier it finds elements of will be scanned for search terms to mark, the rest is ignored. So the order is important here! Start with the element closest to, but still containing all the post/page title, excerpt or content.

  4. hlst_events — The array of DOM event listeners that the inline script will watch for. Default: ['DOMContentLoaded','post-load'] (on Document Ready and for Jetpack Infinite Scroll and others).

  5. hlst_inline_script — The inline script that will be added to the plugin script file. Can be used to add to or alter the inline script. Must return a string.

Известные проблемы & разработка

  1. If your theme does not wrap the main content section of your pages in a div with class «hentry» or HTML5 article tags, this plugin might not work well for you out of the box. However, you can make it work. See the last of the FAQ’s for an explanation.

  2. Josh pointed out a conflict with the ShareThis buttons plugin. Since then, that plugin has been completely rewriten so please let me know if the problem still exists. Thanks!

Часто задаваемые вопросы

Инструкция по установке

To make it work, you will need to take up to three steps, depending on your wishes and WordPress theme. (I) A normal installation and activation procedure; (II) Make sure your theme uses any of the recognized classes or ID’s for the post content div so that the script knows where and where not to look for search terms;
and (III) optionally add CSS styling rules to get highlighting for older browsers that do not support HTML5 like Internet Explorer 8 and below.

I. Install now or use the slick search and install feature (Plugins > Add New and search for «highlight search terms») in your WP2.7+ admin section or follow these basic steps.

  1. Скачать архив и распаковать.
  2. Загрузите (и перезапишите) папку /highlight-search-terms/ и ее содержимое в папку /plugins/.
  3. Активируйте плагин на странице Плагины

II. In most up to date themes (including WP’s own Default theme) post and page content is shown inside an ARTICLE element or DIV with class hentry.
This is recognized by the hilite script, which means search terms found in post and page content will be highlighted but not similar terms that coincidentally reside in the page header, menu, sidebar or footer.

If your current theme does not use these common designations (yet), this plugin will look for some other possible tags like #content, MAIN, #wrapper (which might include the header, sidebar and footer areas) and finally the BODY.

If this causes issues on your theme, see the last of the FAQ’s for ways to make it work.

III. Optionally add at least one new rule to your themes stylesheet or the Custom CSS editor to style highlightable text.

For example use .hilite { background:#D3E18A; } to get a moss green background on search terms found in the content section (not header, sidebar or footer; assuming your Theme uses a div with class «hentry»).

Please find more examples in the FAQ’s below.

Я не вижу никакой подсветки!

This plugin has no configuration options page and there is no predefined highlight styling. For any highlighting to become visible in browsers that do not support HTML5 like Internet Explorer 8 or older, you have to complete step III of the installation process.
Edit your themes stylesheet (style.css) or the WordPress theme customizer Custom CSS tab to contain a rule that will give you exactly the styling that fits your theme.

If that’s not the issue, then you might be experiencing a bug or plugin/theme conflict. Time to get some Support 🙂

Я хочу настроить подсветку, но понятия не имею, что добавить в свою таблицу стилей. Можете ли вы привести несколько примеров?

Перейдите в раздел администратора WP на Внешний вид > Настроить > Пользовательский CSS и добавьте один из приведенных ниже примеров, чтобы начать работу.

For a moss green background highlighting:

.hilite {
    background-color: #D3E18A;
}

Подсветка желтым фоном:

.hilite {
    background-color: yellow;
}

Светло-голубой фон с жирным шрифтом:

.hilite {
    background-color: #9CD4FF;
    font-weight: bold;
}

Оранжевый фон с черным шрифтом:

.hilite {
    background-color:#FFCA61;
    color: #000000;
}

Please give me more advanced CSS examples

If you want to give different terms used in a search phrase a different styling, use the class «term-N» where N is a number starting with 0, increasing 1 with each additional search term, to define your CSS rules.
The below example will make every instance of any term used in the query show up in bold text and a yellow background except for any instance of a second, third and fourth term which will have respectively a light green, light blue and orange background.

/* Default highlighting, but bold text. */
.hilite {
    background-color: yellow;
    font-weight: bold;
}
/* Moss green highlighting for second search term only. */
.term-1 {
    background-color: #D3E18A;
}
/* Light blue highlighting for third search term only. */
.term-2 {
    background-color: #9CD4FF;
}
/* Orange highlighting for fourth search term only. */
.term-3 {
    background-color:#FFCA61
}

Keep in mind that for the first search term the additional class «term-0» is used, not «term-1»!

Terms outside my post/page content get highlighted too

The script will search through your page source code for viable sections that usually contain page or post content, most commonly used in WordPress themes. Like ARTICLE or a DIV with class «hentry». If that is not available, the script will look for other commonly used divs like #content, #main, #wrapper. However, in your particular theme, none of these divs might be available…

Let’s suppose your theme’s index.php or single.php has no <div <?php post_class() ?> ... > but wraps the post/page content in a <div id="someid" class="someclass"> ... </div>. This will not be recognized by the script as a post/page content container and the script will default to highlighting starting with the BODY element.

Это приведет к выделению терминов в заголовке, меню, боковой панели и нижнем колонтитуле.

Вы можете сделать одну из трех вещей, чтобы решить эту проблему:

A. Change your theme templates like single.php, page.pho and search.php so the post/page content div has a class «hentry» (you can append it to existing classes with a space like class="someclass hentry").

B. Добавьте фильтр в файл functions.php вашей темы (или отдельный файл плагина) следующим образом:

add_filter(
    'hlst_selectors',
    function( $selectors ) {
        // custom theme selectors (change and append as needed)
        $my_selectors = array(
            'div.someclass'
        );
        return $my_selectors + (array) $selectors;
    }
);

C. Переключитесь на тему, которая соответствует текущим соглашениям WordPress 🙂

I'm using this plugin now for a long time. It's easy to use and provides extra comfort for the visitors of my page. So, this plugin is very useful and I can really recommend it. Also the support by the plugin's author is very fast and a solution for a problem is provided in a short time. There is nothing what could be done better!
