Velocity "assigning" values to dynamic-metadata if the field is blank
I've got a content-index block that I'm using to build a staff
directory. Some of the content we are using is pulled from dynamic
metadata fields. I've tried to account for some staff not having
data in those fields, by checking to see if they are empty and
using an #if statement.
related velocity:
#foreach ($doc in $docs)
#set ($docsTitle=$doc.getChild("display-name"))
#set ($docsPath = $doc.getChild("link").value)
#set ($docName = $doc.getChild("name"))
#set ($imageName = $doc.getChild("name").value)
#set ($docLocation = $_XPathTool.selectSingleNode($doc, "dynamic-metadata[name='primary-location']/value").value)
#set ($docSpecialty = $_XPathTool.selectSingleNode($doc, "dynamic-metadata[name='primary-specialty']/value").value)
#set ($imageCheck = $_.locateFile("_common/images/providers/${imageName}.png"))
<div class="top-Find-Doctor-container cf">
<div class="Find-Doctor-left">
<h2><a href="${docsPath}"> $_EscapeTool.xml($docsTitle.value)</a></h2>
#set ($hasSpec = $_XPathTool.selectSingleNode($docs,"dynamic-metadata[name='primary-specialty' and value != '']/value"))
#if ($hasSpec)
<span>$_EscapeTool.xml($docSpecialty)</span>
#end
#end
Output html:
<div class="top-Find-Doctor-container cf">
<div class="Find-Doctor-left">
<h2>
<a href="site://1.citizensmemorial.com/providers/deanna-holeman"> DeAnna Holeman, LCSW</a>
</h2>
<span>Nephrology</span>
I can't figure out where the Nephrology value is coming from. I don't see it in the index block. If there is data in the dynamic-metadata field, it seems to be displaying the correct info. But when it is blank, I'm seeing random specialties assigned to that staff.
Sample xml from the index block:
<system-page id="5c62696aac1009d0017504cbd038a3f2">

My guess is that the previous item's specialty in the XML is Nephrology. Velocity doesn't scope variables, so you'll need to set the value to blank before populating it to avoid this problem.
For example,

Eric - Thanks! That did the trick.

Hi Lauren,
I believe the main issue is that you were using
$docsas the context element as opposed to$doc, so you would always get a value regardless of the current loop item (ie$doc).I also wanted to note that you are already saving the value of that dynamic metadata field so you don't need the additional
$hasSpecvariable. For example:Please let me know if you have any questions.
Thanks!
