Blogger: How to Implement OR Operation Within b:if Block

We can do logical OR operation using or (keyword) or || (double pipes) in the condition for cond attribute of the b tag, specifically the b:if.

For example, we want to show custom content or executing script only on static page OR item (post):

<b:if cond='data:blog.pageType == "static_page" || data:blog.pageType == "item"'> [...custom content here...] </b:if>

OR:

<b:if cond='data:blog.pageType == "static_page" or data:blog.pageType == "item"'> [...custom content here...] </b:if>

We can put more than two conditions for the OR.

condition-1 || condition-2 || condition-3 || ... || condition-N

OR:

condition-1 or condition-2 or condition-3 or ... or condition-N

OR, WE MIX THEM 😂

condition-1 || condition-2 or condition-3 or ... || condition-N

That actually works! But it will confuse ourselves. Thus, it is recommended to consistently use either one, the || (double pipes) or the or keyword.

Logical AND

In latest Blogger XML, we can actually use the keyword and for AND operation. This is a post about that.
