Why is WP_Query ignoring categories?

Question

WordPress

I do a slug replacement in records through a selection

$query = new WP_Query(' posts_per_page=-1, cat=73,74 ');

posts_per_page=-1normally selects all records, but it is catignored so that I do not specify there. How to specify the categories correctly?

Answer 1

As I understand it, your syntax is wrong. it should be something like this

$query = new WP_Query(' posts_per_page=-1&cat=73,74 ');

or

$query = new WP_Query( array( 'posts_per_page' => '-1', 'cat' => '73,74' ) );
