Hi everyone.
I have a panel that contains a list of links to other dashboards. I need to create a new list item with a link that changes dinamically according to the values of three tokens evaluated inside "eval" blocks. But, as splunk makes it clear, I can't create "eval" blocks inside of a panel. So I wanted to know if there's a way to evaluate these tokens such that they can be used within the scope of the "panel" block.
Thanks in advance,
Pedro

You can use a hidden table like @bowesmana suggests. Or you can use a bare <search/> element without panel, like this:
<form version="1.1">
<label>https://community.splunk.com/t5/forums/replypage/board-id/splunk-search/message-id/242210</label>
<search>
<query>
| makeresults
| eval Link4=https://$token_1$/".$token_2$."/".$token_3"
</query>
<done>
<set token="Link4">$result.Link4$</set>
</done>
</search>
...
<row>
<panel id="panel1">
<title>My Panel</title>
<html>
<style>
...
</style>
</html>
<html>
<li><a href="..." target="..."><b>Link1</b></a></li>
<li><a href="..." target="..."><b>Link2</b></a></li>
<li><a href="..." target="..."><b>Link3</b></a></li>
<li><a href="$Link4$" target="..."><b>$Link4</b></a></li>
</html>
</panel>
</row>
</form>

Hi @pedropiin
You could create a field returned by the SPL of your search which has an _ (underscore) prefix, this wont be rendered in the visualisation but can be used in the drilldown.
e.g.
| eval _link="https://".$domain$."/".$path$🌟 Did this answer help you? If so, please consider:

Hi @livehybrid
I dont have a drilldown. Its simply a panel of the format:
<panel id="panel1">
<title>My Panel</title>
<html>
<style>
...
</style>
</html>
<html>
<li><a href="..." target="..."><b>Link1</b></a></li>
<li><a href="..." target="..."><b>Link2</b></a></li>
<li><a href="..." target="..."><b>Link3</b></a></li>
</html>
</panel>- Mark as New

Hi @pedropiin
Where do the values currently come from that you want to use within your eval?

I don't know what you mean when you say you can't create eval blocks inside a panel, you can do pretty much whatever you like inside a panel, e.g. you can do this
<panel id="panel1">
<title>My Panel</title>
<html>
<style>
...
</style>
</html>
<html>
<li><a href="..." target="..."><b>Link1</b></a></li>
<li><a href="..." target="..."><b>Link2</b></a></li>
<li><a href="..." target="..."><b>Link3</b></a></li>
<li><a href="..." target="..."><b>$Link4$</b></a></li>
</html>
<table depends="$hidden_table$">
<search>
<query>
| makeresults
| eval Link4=https://$token_1$/".$token_2$."/".$token_3"
</query>
<done>
<set token="Link4">$result.Link4$</set>
</done>
</search>
</table>
</panel>so you have a hidden table inside the panel that performs any search you want and creates any kind of value you need, then the done clause creates the new Link4 token from your result and that $Link4$ token is then used in the <html> section of the panel.

Hi @pedropiin
Is this as a classic XML dashboard or in Dashboard Studio?
Are you able to share what you currently have?

Hi @livehybrid. Its a classic XML dashboard. I'm "coding" it without using Dashboard Studio.
My dashboard is pretty big, so I'm afraid I can't share my code. But this panel with the list is one of the first elements of the dashboard.
Thanks,
Pedro

@pedropiin
Make a hidden search and set your tokens.
And use the token inside your panel.
<row depends="$alwaysHide$">
<panel>
<search id="token_generator">
<query>
| makeresults
| eval tokenA="value1", tokenB="value2", tokenC="value3"
| eval dynamic_link="/app/search/dashboard_name?fieldA=".tokenA."&fieldB=".tokenB."&fieldC=".tokenC
</query>
<done>
<set token="myDynamicLink">$result.dynamic_link$</set>
</done>
</search>
</panel>
</row>
<panel>
<html>
<ul>
<li><a href="$myDynamicLink$">Dynamic Dashboard</a></li>
</ul>
</html>
</panel>Regards,
Prewin
