Variables in Blockeditor-Snippets

Luke

Hi,

I'm currently setting up a website and for special html-structure with rows I'm using the "+blocks"-Editor. Every row is a snippet-item in the "+blocks"-Editor. So that snippet is used several times in the same "+block"-Variable.

In my snippet I'm using variables like @{ :headline } or @{ :image }.

The problem I'm struggling with is, when I for example set a value for the variable @{ :image } in the first use of the snippet in the +blocks-Editor this value is used in all other following snippet-items even there is no value for @{ :image }. I've tried to reset the value of @{ :image } if no image exists with <@ set { :image: '' } @> in a following item but actually I've found no way to "clear" the variable so it has no content and is emty. Every snippet uses the value of the first set of @{ :image } even if it's emty or doesn't exist.

Is there a way to do "clear" a value?

I hope this description of my problem is clear enough 😄

Thanks for your help!

I also noticed that control structures in a snippet, which is used in +blocksEditor, like

<@ if @{ :variable } = 'test' @> Do this <@ else @> Do that <@ end @>
always results in the output always of

"Do this Do that"

No matter which value @{ :variable } has 🤔. It seems like the if-else structure will be complety ignored.

Luke Hi, empty strings get filtered from the data when rendering the page. But you can set them to false or even 0. I have just tested the following example, split into two blocks:

<@ set { :test: 10 } @>
<@ if @{ :test } > 1 @>
    yes
<@ else @>
    no
<@ end @>

The first block gives me the output "yes".

<@ set { :test: false } @>
<@ if @{ :test } > 1 @>
    yes
<@ else @>
    no
<@ end @>

That one results in "no" and :test is cleared correctly. Both blocks are on the same page in the same block editor.
