Liquid语法报错：Expected end_of_string but found pipe 修复求助

错误原因 #

本次报错由两处不规范的Liquid语法导致：

• 条件判断中使用过滤器的表达式需要用括号包裹，不能直接将管道符写在无括号的判断逻辑里
• Liquid的逻辑或运算符是关键字or，不支持||写法
  另外原代码开头有两行冗余的判断语句，位于for循环外部不存在forloop变量，运行也会触发错误，已同步删除。

修复后代码 #

<div class="impact-items">
 {% for block in section.blocks %}
  {% if (forloop.index0 | modulo: 3) == 0 %}<div class="row">{% endif %}
  <div class="impact-content col-xs-12 col-md-4">
   <div class="impact-icon"><img src="{{block.settings.impact_icon | img_url: 'master' }}"></div>
   <div>
    <div class="impact-number">{{block.settings.impact_number}}</div>
    <div class="impact-text">{{block.settings.impact_text}}</div>
   </div>
  </div>
  {% if forloop.last or (forloop.index | modulo: 3) == 0 %}
   </div>
  {% endif %}
 {% endfor %}
 <div class="row">
  <div class="mt2x btn center-xs col-sm-12 col-md-12 col-lg-12 col-xl-12"><a href='https://packedwithpurpose.gifts/our-impact/impact-report-2020/'><button>Learn More About our Impact</button></a></div>
