subcontent inf FTL when exists

[Robert Gan]

hey,

I get content from Database with:

<@renderSubContent subContentId="SOME_CONTENT_ID" />

this works fine as long as this resource exists. But is there a possibility to check if it exists to avoid error messages?

I mean sth like "?if_exists" like the check with FTL variables.

Hi Robert,

You have two choices :
1. improve the macro to check the real existance of content
2. add before call the macro some code like this :
<#if SOME_CONTENT_ID?has_content>
<#assign content=delegator.findOne( "Content",
org.ofbiz.base.util.UtilMisc.toMap("contentId", SOME_CONTENT_ID), true)/>
<#if content?has_content><@renderSubContent
subContentId="SOME_CONTENT_ID" /> </#if>
</#if>
