Wordpress - Themes and Appearance

You added this code to your theme's functions.php to register a sidebar:

register_sidebar('name' => 'Blog Sidebar', 'id' => 'blog-sidebar');

But the sidebar does not appear in the Widgets admin area. What is the error?

AThe sidebar name cannot contain spaces

BThe function call is missing an array around the arguments

CThe function name should be <code>add_sidebar</code> instead of <code>register_sidebar</code>

DThe sidebar ID must be numeric, not a string

Step-by-Step Solution

Solution:

Step 1: Check the function syntax
The register_sidebar() function requires an array of arguments, but the code passes arguments without an array.
Step 2: Identify the fix
Wrapping the arguments in array() or [] is necessary for correct registration.
Final Answer:
The function call is missing an array around the arguments -> Option B
Quick Check:
register_sidebar() needs array argument [OK]

Quick Trick: Always pass an array to register_sidebar() [OK]
