How to retrive info from query string and pass into component in Lithium

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 

We 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: 

  1. Where should check that component is used in admin of Lithium?
  2. How can we parse parameter from URL after /bg-p and then pass that parameter to component recent-blog-posts?
    1. 11112222
    2. Reviews
    3. LetsInspire
    4. NewAtDigi

Thanks,

Mickey

    You can use the freemarker split function to get the last part of the URL

    <#assign url = http.request.url />
<#assign parts = url?split("/") />

        1. If you want to get the last part of the URL then you have to split it with "/" and need to fetch only last part like below

        <#assign url = http.request.url />
<#assign parts = url?split("/") />
<#assign required_part = parts[(parts?size)-1] />
${required_part}

        It will print the last part of the page URL

        11112222
        Reviews

        2. If there is the single parameter like mentioned in your new URL(https://community.lithium.com?category=123) then you can split it with "=" and get the last part.  See here https://prnt.sc/j12wot

        3. If you are on blog page or category page and just want to get the last part of the URL then you can use ${coreNode.id} 

         

        LMK the exact URL from which you want to get the last part of the URL.
