我是PHP的新手，我购买了一个主题，我需要自定义注册表。默认情况下，这些字段都是必需的，唯一的方法是自定义。如何将"必需"类替换为可选类？最后，如果我还可以将 URL 输入更改为文件上传（csv 提要和徽标）。提前感谢伙计们

根据您购买的模板的设计方式，您应该能够删除<span class="required">*</span>。 此时，输入字段应处于默认状态，这将允许用户输入（或不输入）信息。 此外，要完成文件上传，请将<input type="">更改为"文件"
当您看到它只影响窗体的呈现<span class="required">*</span>时，它不包含数据控件。数据控制是在服务器端进行的，这意味着您必须深入研究 PHP 代码以删除对要设置可选字段的检查。告诉我们您使用什么CMS，也许是WordPress？我会相应地更新我的答案。还与我们分享您购买的主题名称。
