我是相當新的PHP，並嘗試過我的手到目前爲止，不成功，以對WordPress主題進行必要的編輯（由MAGEEWP http://www.mageewp.com/onetone-theme.html)which OneTone將允許我替換YouTube視頻滑塊插件。幫助PHP編輯WordPress主題
<?php echo do_shortcode('[smartslider2 slider="1"]');?>
基本上我需要添加添加一個條件或布爾語句到index.php中，例如，如果「節背景視頻」在WP字段設置爲「滑蓋」那麼
echo do_shortcode(‘[smartslider2 slider="1"]‘);
（這樣一個滑塊就會di展開在section-banner .css類中，而不是在WordPress控制面板中指定的YouTube視頻）。
這看起來應該不是一個非常困難的修改，但是我在實際編輯php時有點超出我的深度。任何援助將不勝感激！
下面是從的index.php
<?php

有在WP領域與下面定義的變量直接對應的代碼：
$section_title = onetone_options_array('section_title_'.$i);
$section_menu = onetone_options_array('menu_title_'.$i);
$section_background = onetone_options_array('section_background_'.$i);
$section_background_video = onetone_options_array('section_background_video_'.$i);
$section_css_class = onetone_options_array('section_css_class_'.$i);
$section_content = onetone_options_array('section_content_'.$i);
if(!isset($section_content) || $section_content=="") $section_content = onetone_options_array('sction_content_'.$i);
$section_slug = onetone_options_array('menu_slug_'.$i);
