Is there a way to use an Array for a Query Loop

Hey guys, looking at the Custom Queries for the Loop Builder, it appears that you have to return a WP_Query for the Loop to work.

Is that correct, or is there a way to return a simple Array to use with the loop?

E.g. this could be data from a custom table or API call.

Creating a custom query you can actually fetch and loop through whatever you like:

  1. Add a custom query type
  2. Fetch the results however you like
  3. Loop through the results and prepare them for use

Ah OK,

Do you have an example of how to access the values for dynamic data?

Say if I have an array like
[
[“name”=>“Bob”, “phone”=>“1234567”],
[“name”=>“Peter”, “phone”=>“1234567”],
]

How would I set up and access the values for “name” and “phone” ?

I’m thinking if the dataset is not Posts.

  • Perhaps I need to define a global
  • Set the global value on the ‘bricks/query/loop_object’
  • use {echo:get_my_global_val(key)}

Something to try a bit later.

You could set up a custom query like this:

add_filter( 'bricks/setup/control_options', function( $control_options ) {
    $control_options['queryTypes']['my_query_type'] = esc_html__( 'My Query Type', 'my-plugin' );
    return $control_options;
} );

add_filter( 'bricks/query/run', function( $results, $query_obj ) {
    if ( $query_obj->object_type !== 'my_query_type' ) {
        return $results;
    }
    
    return [
        [
            'name' => 'Bob',
            'phone' => '1234567'
        ],
        [
            'name' => 'Peter',
            'phone' => '7654321'
        ],
    ];
}, 10, 2 );

add_filter( 'bricks/query/loop_object', function( $loop_object, $loop_key, $query_obj ) {
    if ( $query_obj->object_type !== 'my_query_type' ) {
        return $loop_object;
    }

    /* Usually you'd prepare a WP_Post object or something
     * in here (see official documentation).
     * In this specific case there is nothing to do here.
     */
    
    return $loop_object;
}, 10, 3 );

To access the values in Bricks you can use the echo tag with a small helper function like this:

function get_custom_loop_object_property( $name ) {
    $loop_object = \Bricks\Query::get_loop_object();
    if ( ! $loop_object ) return false;
    if ( ! is_array( $loop_object ) ) return false;
    if ( ! array_key_exists( $name, $loop_object ) ) return false;
    return $loop_object[$name];
}

Then you can call it within your query loop using {echo:get_custom_loop_object_property(name)} or {echo:get_custom_loop_object_property(phone)}.

I hope there will be an easy (and documented) way to create custom dynamic tags soon. I’d prefer those over using {echo:xyz} all the time. So @timmse, if you find the time… :sweat_smile:

Ah brilliant. I was not aware of
\Bricks\Query::get_loop_object();

That makes everything make sense now. Thank you for your efforts.

Hi aslotta
Thank you for this code!

I’m trying to return results from a json file. It works if I use return json_decode($file, true).
But I can’t figure out how I could define the maximum number of items, similar to posts_per_page. I’ve tried array_slice, but then I can’t use a load more button.

Do you have any advice?
Thank you very much!

I’ve been looking for this instruction for a long time. Why isn’t this in academy :frowning:
