I am having an issue while register new post type in wordpress. Post slug web-to-print-glossary or web-to-print-glossaries not working, but webtoprint-glossary is working. can someone please explain what is going on?

This is my code

$labels = [
    "name" => esc_html__( "Web to Print Glossary" ),
    "singular_name" => esc_html__( "Web to Print Glossary" ),
];

$args = [
    "label" => esc_html__( "Web to Print Glossary" ),
    "labels" => $labels,
    "description" => "",
    "public" => true,
    "publicly_queryable" => true,
    "show_ui" => true,
    "show_in_rest" => true,
    "rest_base" => "web-to-print-glossaries",
    "rest_controller_class" => "WP_REST_Posts_Controller",
    "rest_namespace" => "wp/v2",
    "has_archive" => false,
    "show_in_menu" => true,
    "show_in_nav_menus" => true,
    "delete_with_user" => false,
    "exclude_from_search" => false,
    "capability_type" => "post",
    "map_meta_cap" => true,
    "hierarchical" => false,
    "can_export" => false,
    "rewrite" => [ "slug" => "web-to-print-glossaries", "with_front" => true ],
    "query_var" => true,
    "supports" => [ "title", "editor", "thumbnail" ],
    "show_in_graphql" => false,
];

register_post_type( "web-to-print-glossaries", $args );

and

CodePudding user response：

It is because of post type key exceeded the characters limit. 20 is the maximum allowed character limit to register post type.

You can find the reference here

CodePudding user response：

WP database reserved for post_type varchar(20) You need trancate your name ("web-to-print-glossaries") to 20 chars. Now it has 23 chars. enter image description here
