How to implement a Custom Counter

[NickyP]

Can anyone tell me how I can add a custom counter to each result item without an ordered list?
What I have is a add to favourites but some names have a identical data-id but if I add a counter teach then I get a unique number.

I have this at the top of my search page <#assign count = 0>
This is what I'm trying to do
<a href="# "data-courseid="${s.result.metaData["A"]!?replace("|", ", ")}_ <#assign count = count + 1>"

this throws an error - completely breaks the page so can someone show me how this is done?

Thanks in advance

Could use just use the rank and adjust as necessary?

Thanks Ian, I've just been given the task of looking after search so I'm a tad rusty plus I updated my question to show the code. Can you give me an example code or point me to the help section on how to use the rank?

Thanks

Hi Nicky,

Try this?

<a href="#" data-courseid="${s.result.metaData["A"]!?replace("|", ", ")}_${s.result.rank!}">

Otherwise your original code wasn't too far off, but instead of just assigning a new value to the count, you'd also need to print the value where you want it:

<#assign count = count + 1>
<a href="#" data-courseid="${s.result.metaData["A"]!?replace("|", ", ")}_${count!}">

Hey Ian, using your options definitely worked so thank you. I am interested however to get my almost original code to work as well however using this still breaks the page, any ideas?

<#assign count = count + 1> or  <#assign count = count++>?
<a href="#" data-courseid="${s.result.metaData["A"]!?replace("|", ", ")}_${count!}">

Does it give you a visible error? Or what does the output HTML look like (view source, not just from the elements panel in dev tools)?

Otherwise I'm not sure, it's a bit tricky to debug without any further information.

It may have been because of the results is a seperate "results.ftl" i.e using
<#import "results.ftl" as Result/>
So when I moved the assign code to the results I didn't get an error but I now am getting a number but its not incrementing - they're all just have a _1
data-courseid="HLB102_1" etc

Thanks
