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

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

1. 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/j14ehe

3. 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!

PS: The link to your stage instance of Lithium is blocked by .htaccess, therefore nobody can see your demo-links

I have tried them but could not work. You may need review my previous comments to see

What did not work, you need to provide more information if you want help...this is not your official Lithium support...we cannot see what you are doing, therefore you need to be a bit more detailed in the description of your issues...

if I go to try.freemarker.org

and enter this in the template field:

<#assign url = "https://communitystg.digi.com.my/t5/Blog/bg-p/11112222" />
<#-- 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}

it works perfectly, outputting "11112222"...so if that's not what you want, then you have to be more specific.

Hi,

Sorry make you confuse. I though you followed screenshot and code I sent before.

I am using code you shared under component. And I do not fix URL "https://communitystg.digi.com.my/t5/Blog/bg-p/11112222"

I retrieve request URL under component.

And it always display url = https://communitystg.digi.com.my/t5/util/componentrenderpage/component-id/recent-blog-posts?render_behavior=raw&page=1 

instead of https://communitystg.digi.com.my/t5/Blog/bg-p/11112222 as display on address bar.

Please check screenshot as below.

My expect: can get url of address bar in component

<#assign url = http.request.url /> 

url should be https://communitystg.digi.com.my/t5/Blog/bg-p/11112222 so then I can use split function as you provided to get "11112222" for query data later.

Thanks for your support.

I'm not sure, but it seems that what

coreNode.id

returns 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>

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,

It does not work.

Please look at screenshot below.

Thanks
