Link not displaying in conditional field display

JaredPilbeam1 — Wed, 20 Sep 2017 16:25:45 GMT

Thanks to this recent blog post: https://community.esri.com/community/gis/web-gis/arcgisonline/blog/2017/07/18/conditional-field-display-with-arcade-in-pop-ups

I have a bunch of points on my web map that are tourist attractions. Some have websites available, some do not. But, they're all in the same attribute table. I have a "URL" field, and when relevant there's a url to the website. This is where the post came in handy. I was able to copy the conditional Arcade line and HTML code that I tailored to my app.

The only thing is that my attribute field is dealing with a link. It's currently showing up as text on the pop-up (visible in the background here). It doesn't seem to be a case of using the link tool in the Custom Attribute Display window because most are individual links. Would you have an idea how to configure it so the link is live?

Jared,

It should be as simple as adding a HTML Anchor element to your last line in the Custom Attribute Display dialog.

{expression/expr0} <a href='{URL}' target='_blank'>your link text</a>‍‍

Robert,

Thanks for the reply.

Sorry, I don't know any HTML. I put your line in and at first it seems like everything was good. I checked some pop-ups that would have a website in the attributes and the link brought me to the right website. But, now the link is showing up on pop-ups of the same attribute table that do not have any websites. So, when you click on the link it brings you back to the web map on a new tab. Also, there's still the text for the link in the pop-up that's not active--not sure how to remove it (see screen shot below).

Here's the whole code:

<table cellpadding="0px" cellspacing="3px">
     <tbody>
           <tr valign="top">
               <td><b>Name:</b></td>
               <td><span>{NAME}</span> 
               </td>
            </tr>
            <tr valign="top">
               <td><b>Address:</b></td>
               <td>{FAC_ADDY_1}</td>
            </tr>
            <tr valign="top">
              <td><br /></td>
              <td>{CITY_ST_ZIP}</td>
            </tr>
           <tr valign="top">
               <td><b>{/expr0}<a href="{URL}" target="_blank">Website</a>
               </b></td><td>{URL}</td>
           </tr>
      </tbody>
</table>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Was able to remove the unwanted text. I erased URL in the Display window. Just the rest of it to figure out now.

Jared,

Great. Don't forget to mark this question as answered.

Robert,

I'm actually still hung up on one thing. If you look at my first reply to your original reply you'll see there's a problem with the link showing up on pop-ups that do not have a website in the attributes, thus they shouldn't have a link. It's like the problem I was having before I found out about the Arcade conditional expression.

RobertScheitlin__GISP — Wed, 20 Sep 2017 20:26:17 GMT

Jared,

Oh, in that case then the whole

<a href="{URL}" target="_blank">Website</a>‍

part needs to go in your arcade expression then.

Re: Link not displaying in conditional field display

JaredPilbeam1 — Wed, 20 Sep 2017 21:21:29 GMT

Do you mean this, or the part of the HTML that calls the expression? I was pasting it here and there both in the Custom window and in the HTML, but not to the right effect.

Re: Link not displaying in conditional field display

RobertScheitlin__GISP — Wed, 20 Sep 2017 21:26:50 GMT

My suggestion would be change what you have in your dialog window above to this:

IIF(IsEmpty($feature.URL), '', '<a href="{URL}" target="_blank">Website</a>‍')‍‍

Robert,

Ok, thanks. Now there's a different problem. After putting that line in the Arcade dialog window, the link still appears on the popups that have no website. And whereas before the link on these would bring you to the same web map on a different tab, it now opens a new blank tab.

Jared,

That is strange as the

{expression/expr0}

should now only be returning an html anchor string if there is anything in the URL field otherwise it is returning an empty string. So what does your Custom attribute display dialog look like now?

It should just be:

Name: {NAME}
Address: {FAC_ADDY_1}
{CITY_ST_ZIP}
{expression/expr0}

Here's the display:

Here's the HTML:

<table cellpadding="0px" cellspacing="3px">
     <tbody>
           <tr valign="top">
               <td><b>Name:</b></td>
               <td><span>{NAME}</span> 
               </td>
            </tr>
            <tr valign="top">
               <td><b>Address:</b></td>
               <td>{FAC_ADDY_1}</td>
            </tr>
            <tr valign="top">
              <td><br /></td>
              <td>{CITY_ST_ZIP}</td>
            </tr>
           <tr valign="top">
               <td><b>{/expr0}<a href="{URL}" target="_blank">Website</a>
               </b></td><td><br /></td>
           </tr>
      </tbody>
</table>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Here's the Arcade expression:

IIF(IsEmpty($feature.URL), '', '<a href="{URL}" target="_blank">Website</a>')‍

You'll notice in the screen shot a popup in the background. It's a popup that shouldn't have a link as there's nothing in the URL field for it.

RobertScheitlin__GISP — Fri, 10 Dec 2021 23:02:35 GMT

So what you should have in the html is just:

<table cellpadding="0px" cellspacing="3px">
     <tbody>
           <tr valign="top">
               <td><b>Name:</b></td>
               <td><span>{NAME}</span> 
               </td>
            </tr>
            <tr valign="top">
               <td><b>Address:</b></td>
               <td>{FAC_ADDY_1}</td>
            </tr>
            <tr valign="top">
              <td><br /></td>
              <td>{CITY_ST_ZIP}</td>
            </tr>
           <tr valign="top">
               <td><b>{expression/expr0}</b></td>
               <td></td>
           </tr>
      </tbody>
</table>

Hi Robert,

After talking with Esri, I found out there was an existing bug behind this behavior:

BUG-000106245: When using a custom attribute display pop-up with a hyperlink field, null values in the hyperlink field result in a link to the current web map.

This was supposedly fixed at the latest release of AGOL they say. The behavior I'm experiencing with the text appearing in the pop-up for fields with null values, even though the Arcade expression tells it otherwise is a new defect. So, they're looking into it. It sounds like, once treated, the URL field will display the hyperlink when present and nothing when the field's null, thereby eliminating the need for the Arcade expression.

Does anyone know if this has been fixed? I'm trying to do the same thing as the original poster but I'm running into the same problems. The bug still appears to exist. Anyone have any updates?

Jared Pilbeam‌ I am still having this issue. I check the bug status and it says it was updated Sep 2019. However, when I try to create a conditional hyperlink, the link text always shows, even when there is no URL. Any solutions for this?

So I had a similar problem in my web map as I only wanted traffic cameras that have an IP address to show a link, and for those that do not, nothing. This was my work around.

1)Create two Arcade Expressions, one for the conditional field display, and one for a conditional link display.
Here is the conditional field display {expression/expr0}

IIF(IsEmpty($feature.CameraIP), '', "Traffic Camera")

Here is the conditional link display named {expression/expr1}

IIF(IsEmpty($feature.CameraIP), '*No Camera Installed*', "Live View")

2) I modified my Customer Attribute display where my field expression is on the left and my link expression is on the right, highlight the link expression and click on the link icon (chain link) :

3) The link window opens and I put my link expression in the "Text" parameter and my camera IP field in the "URL" parameter.

Results:

Traffic Signal with a Camera:

Traffic Signal WITHOUT a Camera IP:

I hope this helps! Shout out to Bernard Szukalski for giving me some direction to go on this solution.
