[solved] ECB2 Extended Content Blocks 2 - "read" variables

I'm probably missing something obvious here.
My goal is to have a tick box on the back end of each page. The tick box determines whether a column is shown with a Twitter widget.
At the end of the page template I have:
Code: Select all
{content_module module="ECB2" field="checkbox" block="showtwitter" label="Show Twitter column" default_value="0" description="Tick to show the Twitter column on the right hand side of this page"}
This works in that it shows the tick box when I am editing the page and I can tick it and it saves. So that's great.
How do I then "read" this variable?
I tried displaying {$showtwitter} in the page template - nothing.
I also tried adding assign="test1" to the original code but got nothing when I tested for $test1.
Tried the module help but it doesn't explain how to access the variables.
What I want to do in the template is something like this:
{if $showtwitter}
<!-- extra content to show here -->
{/if}
Thanks!

I would venture saying that you would need to assign it to the variable:
Code: Select all
{content_module module="ECB2" field="checkbox" block="showtwitter" label="Show Twitter column" default_value="0" description="Tick to show the Twitter column on the right hand side of this page" assign=showtwitter}
* untested...

Thanks Jo, when I do that and put {$showtwitter} in the template I see nothing on the front end page, I am expecting perhaps a "1" if the box is ticked.

Try {$showtwitter|var_export} to inspect the variable in this case. sometimes printing Boolean values is not all that straight forward... for instance FALSE usually won't print anything and that for debugging purposes can be misleading.

Thanks Jo.
I put <!-- {$showtwitter|var_export} -->
I see <!-- NULL -->

OK then, that means that assigning that way won't work... try:
Code: Select all
{$showtwitter="{content_module module='ECB2' field='checkbox' block=showtwitter label='Show Twitter column' default_value=0 description='Tick to show the Twitter column on the right hand side of this page'}"}{$showtwitter|var_export}
Be careful with the quotes, try to use it as posted otherwise you might have conflicting syntax...

Thanks, I see <!-- '1' --> when box is ticked and <!-- '0' --> when it is not ticked.

Now you can use:
Code: Select all
{if $showtwitter}
<!-- extra content to show here -->
{/if}

Thanks again, I tried that but sadly the extra content does not show when the check box is ticked (or if the check box is not ticked).
