Pass String Parameters to WP REST API

Question

I can pass integer values to WP REST API. But, cannot pass non-numeric characters. It gives error.

This is what I used...

add_action( 'rest_api_init', function () {
    register_rest_route( 'crowdapi/v1', '/register/(?P<id>\d+)/(?P<username>\d+)', array(
        'methods' => 'POST',
        'callback' => 'userCheck',
    ) );
} );

Any idea how to pass strings as well.. ?

Answer 1

I found it myself...

use [a-zA-Z0-9-] instead of \\d for strings

add_action( 'rest_api_init', function () {
    register_rest_route( 'crowdapi/v1', '/register/(?P<id>\d+)/(?P<number>[a-zA-Z0-9-]+)', array(
        'methods' => 'POST',
        'callback' => 'userCheck',
    ) );
} );

Answer 2

这对我/(?P<slug>\\w+) ： /(?P<slug>\\w+)

Answer 3

Try below code for define endpoint as well..

add_action( 'rest_api_init', function () {
    register_rest_route( 'crowdapi/v1', '/register/(?P<id>\d)/(?P<username>\d)', array(
        'methods' => 'POST',
        'callback' => 'userCheck',
    ) );
} );
