私のWPブログでSmart Syntaxプラグインを使用しています。それはGoogleのprettifyを利用して構文を強調表示します。PHP：WordPressブログのホームページにプラグインを作成する
私のカスタムCSSルールでは構文の強調表示が完全に機能しますが、ホームページに投稿を表示したときにCSSを自分の投稿に適用するJavascriptが適用されていないようです。ここで
は、プラグインのfunctions.phpです：
<?php
function smart_syntax_prettyprint($content)
{
global $post;
global $comment;
$seeker = "/(<pre)(.+)(<code.+class.+[\'\"])([^\'\"]+)([\'\"]>)/i";
$prettified = '$1 class="prettyprint lang-$4"$2$3$4$5';
$content = preg_replace($seeker, $prettified, $content);
return $content;
}
function smart_syntax_prettify_script()
{
global $post;
global $comment;
$content = $post->post_content . $comment->comment_content;
$smart_syntax = get_option('_smart_syntax_options');
$output = preg_match_all('/(<pre)(.+)(<code.+class.+[\'"])([^\'"]+)([\'"]>)/i', $content, $matches);
// find language tags
if (!empty($matches[0]) && isset($matches[0])) {
$langs = smart_syntax_remove_dupe_langs($matches[4]);
foreach ($langs as $lg) {
if ($lg = 'css') {
$lang = $lg;
}
}
}
if (is_singular() && !empty($matches[0]) && isset($matches[0])) {
if (!empty($lang) && isset($lang)) {
$suffix = '?lang=' . $lang;
}
if (isset($smart_syntax['cdn_prettify']) && $smart_syntax['cdn_prettify'] == true) {
$source = 'https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js' . $suffix;
} else {
$source = SMART_SYNTAX_URL . 'assets/js/src/run_prettify.js' . $suffix;
}
wp_enqueue_script('smart-syntax-prettify', $source, null, null, true);
?>
<script>prettyPrint()</script>
<?php
if (isset($smart_syntax['custom_skin']) && $smart_syntax['custom_skin'] == true) {
wp_enqueue_style('smart-syntax-skin', SMART_SYNTAX_URL . 'assets/css/smart_syntax.css', true, '1.0.0');
} elseif ($smart_syntax['custom_skin'] != true && $smart_syntax['cdn_prettify'] != true) {
wp_enqueue_style('smart-syntax-skin', SMART_SYNTAX_URL . 'assets/css/prettify.css', true, '1.0.0');
}
}
}
function smart_syntax_remove_dupe_langs($array)
{
foreach ($array as $lang => $val)
$sort[$lang] = serialize($val);
$uni = array_unique($sort);
foreach ($uni as $lang => $ser)
$sorted[$lang] = unserialize($ser);
return ($sorted);
}
そして、ここではsmart_syntax.phpです：
function smart_syntax_init() {
$locale = apply_filters('plugin_locale', get_locale(), 'smart_syntax');
load_textdomain('smart_syntax', WP_LANG_DIR . '/smart_syntax/smart_syntax-' . $locale . '.mo');
load_plugin_textdomain('smart_syntax', false, dirname(plugin_basename(__FILE__)) . '/languages/');
require_once SMART_SYNTAX_PATH . 'includes/functions.php';
require_once SMART_SYNTAX_PATH . 'includes/admin-menu.php';
}
/**
* Activate the plugin
*/
function smart_syntax_activate() {
// First load the init scripts in case any rewrite functionality is being loaded
smart_syntax_init();
}
register_activation_hook(__FILE__, 'smart_syntax_activate');
/**
* Deactivate the plugin
* Uninstall routines should be in uninstall.php
*/
function smart_syntax_deactivate() {
}
register_deactivation_hook(__FILE__, 'smart_syntax_deactivate');
// actions
add_action('init', 'smart_syntax_init');
add_action('admin_menu','smart_syntax_menu');
add_action('wp_enqueue_scripts','smart_syntax_prettify_script');
//filters
add_filter('the_content', 'smart_syntax_prettyprint', 10);
add_filter('comment_text', 'smart_syntax_prettyprint', 10);
、私は非常に少ないPHPを知っています。 add_filter('is_home','smart_syntax_prettyprint', 10);を実行しても役に立ちませんでした。 `
