我的 ColdFusion 代码返回“元素作者在 FORM 中未定义”时遇到问题。每当我提交表格时。我试过使用<cfparam>
设置comment.author
,但它也没有工作。我对 ColdFusion 还很陌生,所以任何推理评论都会很棒!
<cfparam name="form.submitted" default="0" />
<cfset blogPost = EntityLoad('BlogPost',url.id,true) />
<cfif form.submitted>
<cfset comment = EntityNew('BlogComment') />
<cfset comment.author = form.author />
<cfset comment.comment = form.comment />
<cfset comment.createdDateTime = now() />
<cfset blogPost.addComment(comment) />
<cfset EntitySave(blogPost) />
</cfif>
<cfimport taglib="customTags/" prefix="layout" />
