PHP:使插件在WordPress博客的主页上应用

Question

我在我的WP博客中使用智能语法插件。它强调使用谷歌的漂亮语法。

语法突出显示与我的自定义CSS规则很好地配合，但在主页上查看帖子时，似乎没有应用将CSS应用于我的文章的Javascript。

这是插件的functions.php

<?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);
}

这是smart_syntax.php

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);

我对PHP了解甚少。做add_filter('is_home','smart_syntax_prettyprint', 10);没有帮助。`

脚本没有加载到主页的原因是插件有条件地加载脚本，只在单个帖子和页面上加载。

在function smart_syntax_prettify_script()中，您可以从该语句中删除is_singular()：

if (is_singular() && !empty($matches[0]) && isset($matches[0])) {

因此，它的内容如下：

if (!empty($matches[0]) && isset($matches[0])) {

重要注

您将编辑插件本身，因此建议您以某种方式对其进行分叉。否则，当插件作者发布更新时，它将覆盖您的更改并将其还原回。

您还可以与插件作者联系，并要求他们创建一个选项，允许您设置插件应该加载的页面类型。
