Wp_Query on tag based not getting post when use sign

When you use these parameters, you need to pass the category or tag slug, not the actual category or tag name. You can verify the slugs by going to Dashboard > Posts > Categories or Dashboard > Posts > Tags.

@stephencottontail : We have check category slug and have use “,”
post is getting but when use “+” not working this one supported in wordpress latest version.

$query = new WP_Query( 'category_name=facebook,uncategorized' ); (work)

$query = new WP_Query( 'category_name=facebook+uncategorized' );(Not work)

Hmm, the + sign works for tags but not categories. Instead, you should use this syntax if you want to test for multiple categories:

$query = new WP_Query( array( 'category_in' => array( 1, 2 ) ) );

You’ll need to know the IDs of the desired categories.

@stephencottontail : Thanks, I know all of techniques for code.

Today Just i learn to junior developer with this code using “+” sign so not getting posts.

So i post question because Review & test code by moderator and also change on site.

New Defect ticket url

Show Posts From Several Categories (Display posts that have these categories, using category id) would be

$query = new WP_Query( ‘cat=10,11’ );
but i never try with + sign if you get the solution then post here!!

Hi,

The Trac ticket has been updated, but for convenience:

This is because you are submitting a string which is parsed like an URL, you’ll need to either URLEncode the + sign (use %2B instead) or submit the query arguments as an array, WP_Query( array( 'category_name' => 'facebok+uncategorized' ) );, to stop this.

This is sort of expected behavior, as it is a native PHP function called parse_str being ran if you submit the arguments as a string.

@marius I have tested code with this as per u have define code not working.

$query = new WP_Query( 'category_name=facebook%2Buncategorized' );
(working)

$query = new WP_Query( array( 'category_name' => 'facebok+uncategorized' ) );

(Not working)

@ravipatel That’s because you copied and pasted it with my facebook typo ??

@marius Thanks, Now working.

$query = new WP_Query( array( 'category_name' => 'facebook+uncategorized' ) );
