Wordpress - WordPress Query and Database

Examine this pagination code snippet:

$current_page = get_query_var('paged');
$args = ['posts_per_page' => 5, 'paged' => $current_page];
$query = new WP_Query($args);

What is the potential issue with this code?

AIf 'paged' is not set, $current_page will be empty, causing pagination to fail.

BUsing 'paged' instead of 'page' causes the query to ignore pagination.

CThe 'posts_per_page' parameter must be set to 10 for pagination to work.

DWP_Query does not support the 'paged' parameter in custom queries.

Step-by-Step Solution

Solution:

Step 1: Check get_query_var('paged')
If the 'paged' query variable is not set in the URL, get_query_var('paged') returns an empty value.
Step 2: Default to page 1
To avoid issues, you should default $current_page to 1 when 'paged' is empty, e.g., $current_page = get_query_var('paged') ? get_query_var('paged') : 1;.
Final Answer:
If 'paged' is empty, pagination will not work correctly. -> Option A
Quick Check:
Always set a default page number [OK]

Quick Trick: Always default 'paged' to 1 if empty [OK]
