Currently, I have multiple variables:
${top_1}
${top_2}
${top_3}
${top_4}
And I have this conditional logic for a default variable present:
<#if top_1 == "">not available<#else>${top_1}</#if>
How would I include all of the variables and display the default when all fields are missing?
Found the answer.
Expressions like + can tie the multiple variables together. And including the statement at the end of list will include everything without errors.
example:
<#if top_1 + top_2 + top_3 + top_4 == "">not available<#else>${top_1} ${top_2} ${top_3} ${top_4}</#if>
Any kind of styling will work in between that last part of the list as well. Sorry, graphic designer learning Freemarker here.

I am new to freemarker and trying to extract list of value defined within bracket. Example below.. I would like to list values from () so can use it towards assign fucntion.. Couldn't get regex function to work correctly.. Can someone advice?
<alternative-id provider="abc.com" level="episode" description="CHICAGO GO (Sign) (primary) Ep 514">12345678</alternative-id>
<alternative-id provider="abc.com" level="episode" description="NewYork Show (primary) Ep 514">14561234</alternative-id>
<#if model["alternative-id[description=text(\((.*?)\))]"][0]?has_content >
tried regex (((.*?))) to extract the value but don't think freemarker support this. As i am very new to freemarker i am not sure if this is even allowed..
I am receiving a syntax error and having a hard time identifying where I am going wrong.
I have researched several different alternatives such as wrapping <apex outputText> as well as using multiple version of {! leading into my variable calls. Unfortunately, I'm just having a hard time grasping which series of errors I am making to cause this syntax error.
The Crux of the code is:
<td>
{! IF(isTenant, ${woli.Repair_Product__r.Bill_Rate_Retail__c}, ${woli.Repair_Product__r.Bill_Rate__c})}
</td>
For variable References. This is located in a where woli is defined as:
<apex:repeat value="{!woliList}" var="woli">
and isTenant is simply hardcoded in my controller to be false for testing purposes:
public Boolean isTenant = False;
I expected my Apex Repeat command to populate different bill rates depending on the value of isTenant, but of course with the Syntax error I cannot tell if I am on the right track. Helpful tips on when multiple {!} are or are not required in Visual Force references would be helpful. I am also curious when, if ever, I should be using single or double quotation marks to define the output of the if condition.
UPDATE:
I thought perhaps I it was as simple as me not binding the condition statement to a variable in the controller class so I modified to this:
<td>
{! IF({!isTenant}, ${woli.Repair_Product__r.Bill_Rate_Retail__c}, ${woli.Repair_Product__r.Bill_Rate__c})}
</td>
Adding appropriate get/set in the controller. But alas this was not the problem the developer console still gives a mystery Syntax Error.
You don't need $ signs. Dollar is used for special fields that "depends who's looking" and other stuff not really related to data in database. You can have $CurrentPage, $User.Name, $Profile.Name, $Label.someText (that one counts as "depends who's looking" because if your preferred language is French it can display translated version.
And second thing - if you're already inside the {! some merge field syntax } you don't need more curly braces.
Try
{! IF(!isTenant,
woli.Repair_Product__r.Bill_Rate_Retail__c,
woli.Repair_Product__r.Bill_Rate__c
)}
I have HTML and an expression I want to be displayed if the field as a value. If it doesn't, don't display it at all.
{! IF( ISBLANK(GoEvent.Event_Time_End__c), '', '<b>End Time:</b> {!GoEvent.Event_Time_End__c}' ) }
I think I have my condition setup properly, but the HTML isn't rendering and the proper value from the expression isn't displaying. Looks like this.
To get your code to work as you intended you need to wrap your output in an apex:outputText and set escape="false". Note that using escape=false has security implications if you are injecting values the user can edit see: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_security_tips_scontrols.htm
Secondly, the reason you are seeing the # is that you are already inside visualforce syntax with the !IF so no need for the second {!} construct.
Finally I prefer to concatenate the string and visualforce syntax rather than mix.
So a working version would be something like:
<apex:outputText value="{! IF( ISBLANK(GoEvent.Event_Time_End__c), '', '<b>End Time:</b>' + GoEvent.Event_Time_End__c ) }" escape="false"/>
however, given your code is effectively saying only show the output if not null I'd think you are better off with something like this:
<apex:outputPanel layout="false" rendered="{!!ISBLANK(GoEvent.Event_Time_End__c)}">
<b>End Time:</b><apex:outputField value="{!GoEvent.Event_Time_End__c}"/>
</apex:outputPanel>
This is output that is only rendered if the Time isn't blank and output field will localise the time based on user locale etc.
Let me start with I'm not a programmer by trade, but I'm learning the best I can. I'm trying to build a template to take the result of one FreeMarker interpolation result and use that as a variable for another. I hope I'm using the terms correctly.
For example, I want the result of (entity.customer.organization.name) to be used in:
${blurb["organizationXXXAttire"]!}
Where XXX is the result of (entity.customer.organization.name)
If it was just a blurb with out a variable company name it would look like:
${blurb["organizationCompanyAttire"]!}
I thought the following would work but it did not:
<#assign organization = (entity.customer.organization.name)>
${blurb["organization<#organization?interpret>Attire"]!}
Thanks in advance for any suggestions.
It's simply ${blurb["organization${entity.customer.organization.name}Attire"]!}.
?interpret is only needed if you have a string that contains a piece of template. Besides you can't call directives (<#...>, <#...>) inside an expression.
Is there a way to change a subvariable within a hash or a container in a FreeMarker template? For example, suppose I had:
{"name":"Bob", "city":"Detroit", "state":"OH"}
and I want to change the state to "MI". How would I go about doing that? I know about the assign tag, but the documentation says "Note that only top-level variables can be created/replaced". I am unsure as to whether this means subvariables can't be replaced with the assign tag, or subvariables can't be replaced by any means.
I figured out a simple way to do it:
<#assign hash = hash + {"state":"MI"}>
