Hi Support Team, I have tried to check how component in Lithium queries data for 4 pages above.There is an issue need to get advise from Lithium support.Scenario:Once we access URL as below http://community.digi.com.my/t5/Blog/bg-p/11112222http://community.digi.com.my/t5/Reviews/bg-p/Reviewshttp://community.digi.com.my/t5/Let-s-Inspire/bg-p/LetsInspirehttp://community.digi.com.my/t5/New-Digi/bg-p/NewAtDigiWe want to get last part of URL in this case is "Reviews" and then pass that parameter to component name "recent-blog-posts"And in component we will get parameter by using code as below<#assign category = http.request.parameters.name.get("category", "") />Question: Where should check that component is used in admin of Lithium?How can we parse parameter from URL after /bg-p and then pass that parameter to component recent-blog-posts?11112222ReviewsLetsInspireNewAtDigiThanks,Mickey

I'm not sure, but it seems that what coreNode.idreturns is not the blog, but the id of your instance/community, to what quilt/page (like BlogPage etc.) do you add this custom component? Is it doing the same if you copy the entire code into a differently named component (like "cmp.blog.recent")? (might be that there is a standard component with the same name, just a guess...that could cause trouble). you could kind of make your code more robust by checking that you are on a blog node, like: <#if coreNode.nodeType == "blog"> // do your stuff<#else> // not in a blog node </#if>

I also tried as below code in component recent-blog-posts<#assign url = http.request.url /><#assign parts = url?split("/") /><#assign category = parts[(parts?size)-1] />Hello category ${category} You can see result at https://communitystg.digi.com.my/t5/Blog/bg-p/11112222 Hello category = recent-blog-posts?render_behavior=raw&page=1 It should be Hello category = 11112222 Could you please advise how to retrieve 11112222? Thanks

kiettuongwork1. Add below line in a custom component https://prnt.sc/j14dzs<#assign Blog_id = coreNode.id />Blog id = ${Blog_id}2. Add the component on blog page https://prnt.sc/j14ehe3. Check the value on the blog page https://prnt.sc/j14df3

Thanks for your reply.But it does not work https://communitystg.digi.com.my/t5/Blog/bg-p/11112222

kiettuongwork there are several things you can try, I would do it as follows: <#-- assuming URL: https://communitystg.digi.com.my/t5/Blog/bg-p/11112222 with the goal to extract the number at the end, e.g. 11112222 --> <#assign url = http.request.url /> <#-- first split away any URL parameters, that's the stuff after a question mark "?" what you seem to want is a url-path element, basically what we want is everything before a possible question mark --> <#assign urlparts = url?split("?")?first /> <#-- we then split that first part at every slash "/" --> <#assign urlparts = url?split("?")?first?split("/") /> <#-- and eventually select just the last bit of that sequence to get what you want --> <#assign urlparts = url?split("?")?first?split("/")?last /> <#-- of course you do not need to do that assignment 3 times, once is enough, e.g. like this: --> <#assign urlparts = url?split("?")?first?split("/")?last /> ${urlparts} hope it helps!

Blog id is = ${coreNode.id}

this one should work if the url is http://community.digi.com.my/t5/Blog/bg-p/11112222

it should return 11112222

    Hi kiettuongwork,
    
    What are you trying to do with your recent-blog-posts component? What is the component's purpose? Is there a reason why you are choosing to pass these blogs by parsing the URL instead of using a call to the Community API via the rest FreeMarker context object? I'm wondering if there is an easier way to accomplish your task.
    
    Have you seen either of these TKB articles?
    
    Building your first custom component - Note this article uses Community API v1
    
    Update a component from API v1 to v2

I also tried as below code in component recent-blog-posts
<#assign url = http.request.url />
<#assign parts = url?split("/") />
<#assign category = parts[(parts?size)-1] />
Hello category ${category}

You can see result at
https://communitystg.digi.com.my/t5/Blog/bg-p/11112222

Hello category = recent-blog-posts?render_behavior=raw&page=1

It should be Hello category = 11112222

Could you please advise how to retrieve 11112222?

Thanks
