Need assistance with wp_user_query not working - php

Question

I need some help getting a wp_user_query to work; been struggling and trying lots of stuff but cannot get it to work proper way.
here is my code:
$args = array(
'meta_query' => array(
'role' => 'personal-injury-lawyer',
'orderby' => 'meta_value',
'meta_key' => 'lawyer_numeric_rank',
'order' => 'ASC',
array(
'key' => 'lawyer_location',
'value' => 'London',
'compare' => '='
),
)
);
$london_user_query = new WP_User_Query($args);
if ( ! empty($london_user_query->results)) {
foreach ( $london_user_query->results as $user ) {
I know the foreach loop is not closed; just trying shorten this...
I am trying to do three things on this query:
Show roles of personal-injury-lawyer
Show where meta_key field of lawyer_location = London
Order by meta_value where meta_key = lawyer_numeric_rank in ASC order
I have tried this a number of ways but cannot get this to work with both filtering on London location and also ordering by the rank...
The code right now does filter on location; but the orderby part is not working; if i remove the location filter from this; then the orderby does work...
I hope someone can help with this.

Answer 1

you were forming the meta query argument incorrectly. The below code should help you with quite a few more meta queries as well.
$args = array(
'role'=> 'personal-injury-lawyer', //assuming you have created a role that corresponds..
'order' => 'ASC',
'orderby' => 'meta_value',
'meta_key' => 'lawyer_numeric_rank',
'meta_query' => array(
// 'relation'=> 'AND', --> if you want more conditions
array(
'key' => 'lawyer_location',
'value' => 'London',
'compare' => '='
),
/* even more conditions with OR, cumulative effect is match lawyer location AND 1 of the nested arrays
array(
'relation' => 'OR',
array(
'key' => '',
'value' => '',
'compare' => '=',
),
array(
'key' => '',
'value' => '',
'compare' => '=',
),
),
*/
)
);
