第一步

把下面代码添加到主题functions.php文件中

function alu_scripts() {
    wp_enqueue_style( 'admin-myjscss', get_template_directory_uri() . '/static/css/style.css' );
    wp_enqueue_script( 'admin-myjscss', get_template_directory_uri() . '/static/js/index.js' );
}
add_action('admin_head', 'alu_scripts');


add_filter('smilies_src', 'alu_smilies_src', 1, 10);
function alu_smilies_src($img_src, $img, $siteurl) {
    $img = rtrim($img, "gif");
    return get_bloginfo('template_directory') . '/static/img/' . $img . 'gif';
}

function alu_get_wpsmiliestrans() {
    global $wpsmiliestrans;
    $wpsmilies = array_unique($wpsmiliestrans);
    $output = '';
    foreach ($wpsmilies as $alt => $src_path) {
        //$emoji = str_replace(array('&#x', ';'), '', wp_encode_emoji($src_path));
        $output .= '<a class="add-smily" data-action="addSmily" data-smilies="' . $alt . '"><img class="wp-smiley" src="' . get_bloginfo('template_directory') . '/static/img/' . $src_path .'" /></a>';
    }
    return $output;
}

function alu_smilies_reset() {
    global $wpsmiliestrans, $wp_smiliessearch;

// don't bother setting up smilies if they are disabled
    if ( !get_option( 'use_smilies' ) )
        return;

    $wpsmiliestrans = array(
        ':mrgreen:' => 'icon_mrgreen.gif',
        ':neutral:' => 'icon_neutral.gif',
        ':twisted:' => 'icon_twisted.gif',

        '8-)' => 'icon_cool.gif',
        '8-O' => 'icon_eek.gif',
        ':-(' => 'icon_sad.gif',
        ':-)' => 'icon_smile.gif',

        ':-x' => 'icon_mad.gif',
        ':-|' => 'icon_neutral.gif',
        ';-)' => 'icon_wink.gif',
        // This one transformation breaks regular text with frequency.
        //     '8)' => 'icon_cool.gif',
        '8O' => 'icon_eek.gif',
        ':(' => 'icon_sad.gif',
        ':)' => 'icon_smile.gif',
        ':?' => 'icon_confused.gif',

        ';)' => 'icon_wink.gif',
        ':!:' => 'icon_exclaim.gif',
        ':?:' => 'icon_question.gif',
    );
}
add_action('init','alu_smilies_reset');


add_filter( 'comment_form_defaults','alu_add_smilies_to_comment_form');
function alu_add_smilies_to_comment_form($default) {
    $commenter = wp_get_current_commenter();
    $default['comment_field'] .= '<p class="comment-form-smilies">' . alu_get_wpsmiliestrans() . '</p>';
    return $default;
}

注意上面表情图片引用路径，根据自己实际情况修改

第二步

把下载下来的文件里面的static文件夹直接拖到你的主题文件里面

第三步

打开你主题文件里面的comments.php文件 搜索textarea 然后把下面代码放在textarea 之前就行了

<p class="comment-form-smilies"><?php echo alu_get_wpsmiliestrans();?></p>
