使用get_query_vars获取值数组

Question

Say i have an URL "http://example.com/result/?q=test1&color=blue&color=black"

I would like to get an array of values

Resulting in q = test1;and color=[blue, black]

I included my vars in functions.php

function add_query_vars_filter( $vars ){
    array_push($vars,"q","color");
    return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );

But when i use get_query_vars i get only single value and not an array.

Is it even possible to get an array of values?

Answer 1

You need to call your URL with array syntax for parameters that are specified more than once. Note the square brackets:

http://example.com/result/?q=test1&color[]=blue&color[]=black

This yields:

Array
(
    [q] => test1
    [color] => Array
        (
            [0] => blue
            [1] => black
        )

)
