If snippet does not honor empty/notempty in TV

leonie12

I have a long time working website where I have different TV which should be only shown when there is content in the TV.
This works fine with several If calls like this: [[If? &is=`[*longtitle*]:notempty` &then=`<h2>[*longtitle*]</h2>`]]. It works also with this: [*longtitle:notempty:then=`<h2>[*longtitle*]</h2>`*]. And it works not only with longtitle field but with several TV which are of the type "text".
Now I have one TV in the same template as the working ones in the same place 1:1 like the working ones, where it makes no difference if there is content in the TV or not. If I have the If call I get absolutely no output. If I use only the TV without If around I get the output of the TV as normal.
Has anyone suggestions what could cause this behaviour and how to get rid of it?

What I could find out meanwhile is that the problem occurs if I use „notemty“ or „!empty“ or „not=``````“

I could work around it with this: [[If? &is=`[*TV*]:empty` &then=`` &else=`[*TV*]">`]]

This means empty state is detected correctly but notempty not? Is there an obvious explanation?

I often had this issue with If and "!empty" operator. Always solved with the same work around 🙂

I think it has to do/occurs with using multiple IF calls with the same TV or ID.

If nobody has an explanation for this behaviour I would take it for a bug. Who maintains If snippet to file a bug report there? Evo core?

I just noticed this, on a template I'm working on:

I have a TV "[image-credits]" to show the credits of the main image of the article, when necessary:

[[if? &is=`[*image-credits*]:!empty` &then=`<div class="imgcredits text-right small mt-n5 mb-4"><em>[*image-credits*]</em></div>`]]

if the TV [image-credits] contains just plain text (ie:. photo by John Smith), the notempty field is correctly recognized
if the TV [image-credits] contains some html code (ie:. <a href="https://domain.com" target="_blank">photo by John Smith</a>), the notempty field is not recognized

solved with the usual work around:
[[if? &is=`[*image-credits*]:empty` &then=`` &else=`<div class="imgcredits text-right small mt-n5 mb-4"><em>[*image-credits*]</em></div>`]]
