Re: Help with a FTL if

[Jacques Le Roux]

Are you sure to have an instance of productContentWrapper? Else you should have 
something like below before calling what I suggested

<#assign productContentWrapper = productData.productContentWrapper/>

see compareproducts.ftl[109] for instance

To prasath: ! is the same as ?default(). There are examples in OFBiz

Hi Hardik and Jacques - tried both that and also does not work.

So far the only solution would be to hope that one product does not have both a 
description and a long_description and use:
${productContentWrapper.get("DESCRIPTION")}
${productContentWrapper.get("LONG_DESCRIPTION")}

Very fustrating!

${productContentWrapper.get("DESCRIPTION")}

<#elseif productContentWrapper.get("LONG_DESCRIPTION")?exists >
${productContentWrapper.get("LONG_DESCRIPTION")}

</#if>


This should do the trick

Thanks for the help but that didn't work either!?

If the long_description is called first then where there is a long
description on a product it shows the long description but does not show the
description on products where there is no long description and only a
description and most annoyingly if the description is called first then it
shows description but not the long description on products that don't have a
description but do have a long description.

sam,

I hope we cannot use has_content with not existing variables. So, I

suggest

to use 'exists' before has_content

#if productContentWrapper.get("DESCRIPTION")?exists?has_content>
                 ${productContentWrapper.get("DESCRIPTION")}
<#else>
${productContentWrapper.get("LONG_DESCRIPTION")}

</#if>

best wishes

Hi Prasath

Thanks for pointing that out so the revised code should look something

like

this so that if there is no content in description is uses

long_description?

     <#if productContentWrapper.get("DESCRIPTION")?has_content>
         ${productContentWrapper.get("DESCRIPTION")}
         <#else>
         ${productContentWrapper.get("LONG_DESCRIPTION")}
      </#if>

Hi sam,

'exists' will check for existence of the variable.
'if_exists' will check for 'null' value.
if you want to check the value then use has_content.

I hope it will help you.

Hi,

Can someone help me with this if statement - i can only get it to return a
value for long_description if one exists where as I want it to return

a

description if no long_description is found?

        <#assign prodDesc =
productContentWrapper.get("LONG_DESCRIPTION")?if_exists>
        <#if prodDesc?exists>
            ${productContentWrapper.get("LONG_DESCRIPTION")}
        <#else>
            ${productContentWrapper.get("DESCRIPTION")?if_exists}
        </#if>


Thanks
Sam
