我添加了一个基本的联系表格，如Shopify 文档中所述。

我的代码：

{% form 'contact' %}

{% if form.posted_successfully? %}
<div class="successForm feedback">
  <p>Thanks for contacting us. We'll get back to you as soon as possible.</p>
</div>
{% endif %}

{% if form.errors %}
<div class="errorForm feedback">
  <p>Sorry, we were unable to submit your inquiry because it contained {{ form.errors | size | pluralize: 'an error', 'a few errors' }}.<br/>Please correct the following and submit again:</p>
  {% for field in form.errors %}
  <p><strong>The {{ field | capitalize | replace: 'Body', 'Comments / questions' }} field {{ form.errors.messages[field] }}.</strong></p>
  {% endfor %}
</div>
{% endif %}

<div id="contactFormWrapper">
  <h3>Personal details</h3>
  <ul>
    <li>
      <label>First name:</label>
      <input type="text" id="contactFormFirstName" name="contact[first-name]" placeholder="" />
    </li>
    <li>
      <label>Last name:</label>
      <input type="text" id="contactFormLastName" name="contact[last-name]" placeholder="" />
    </li>          
    <li>
      <label>Email address:</label>
      <input type="email" id="contactFormEmail" name="contact[email]" placeholder="" />
    </li>
    <li>
      <label>Telephone number:</label>
      <input type="telephone" id="contactFormTelephone" name="contact[phone]" placeholder="" />
    </li>
    <li>
      <label>City:</label>
      <input type="text" id="contactFormCity" name="contact[city]" placeholder="" />
    </li>
    <li>
      <label>Country:</label>
      <input type="text" id="contactFormCountry" name="contact[country]" placeholder="" />
    </li>
  </ul>
  <h3>Items</h3>
  <ul>
    <li>
      <label>Items:</label>
      <input type="text" id="contactFormItems" name="contact[items]" placeholder="" />

    </li>
    <li>
      <label>Questions:</label>
      <textarea rows="10" id="contactFormComments" name="contact[body]" placeholder=""></textarea>
    </li>
  </ul>
  <div class="clearfix"></div>
  <div class="main-button-container">
    <input type="submit" id="contactFormSubmit" value="Submit Enquiry" class="btn button-style" />
  </div>
</div>

{% endform %}

但是，如果用户尝试提交表单但填写错误，则页面会刷新并显示错误消息并清除所有数据。从用户体验的角度来看，这并不理想，因为用户必须重新输入所有内容。

表单错误后如何保留之前填写的所有数据？请帮忙。

value您可以使用该属性显示提交的数据。例如：

<input type="text" id="contactFormEmail" name="contact[email]" value="{{form.email}}" />

或者对于一个textarea：

<textarea id="contactFormComments" name="contact[body]">{{form.body}}</textarea>

我知道这是一个旧帖子，但我想把它留在这里，以防将来有人（比如我）需要它。{{ form.email }}并且{{ form.body }}是唯一可以以这种方式运行的标签 - 用于电子邮件和正文字段。如果您需要获取其他自定义字段的数据，则需要使用一些技巧。

当表单返回错误时，来自提交字段的数据在页面的查询字符串中可用。FreakDesign有一篇很棒的文章，展示了如何将其拉入您的模板。

不过，我最终不得不对其进行一些定制，以便专门与 Shopify 联系表格一起使用。这对我有用：

{% comment %}
    IF THE FORM THROWS ERRORS, POPULATE THE FORM FIELDS WITH DATA FROM THE QUERY STRING
    NOTE: To use the `{% if form.errors %}` statement below, you must place this code within the `{% form 'contact' %}` tag.
{% endcomment %}
{% if form.errors %}

    {%- comment -%}
