Use Custom Fields to sort post in Query Loop

Hi there,

You may need to use a snippet for that. Can you explain a bit further about how you want to achieve this and which plugin you are using for the custom field?

Not sure if I’m getting this right, but from what I understand, you’ve added a custom field to each post, and now you want to display the posts based on a specific value of that custom field. Is that correct?

therefore I would like to pull the info from this custom field in a query loop.

I am still not clear, are you talking about the wp tags or the custom field?

If it’s custom field, please check this article: https://docs.generateblocks.com/article/order-query-loop-by-custom-field/

Hi there,

First, add a class to the Grid block inside of the Query Loop: query-by-city

Then, try this:

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {
    // apply filter if loop has class: query-by-city
    if (! is_admin() && ! empty( $attributes['className'] ) && strpos( $attributes['className'], 'query-by-city' ) !== false) {
        $query_args = array_merge(
            $query_args,
            array(
                'meta_query' => array(
                    array(
                        'key' => 'city',
                        'value' => 'Wielicka',
                        'compare' => '=',
                    )
                ),
            )
        );
    }

    return $query_args;
}, 10, 2 );

Let me know if that works or not 🙂

Not without it affecting the query, which we don’t want here.

One possibility is to use the Custom Attributes feature in the Grid block.

You could do something like this:

key: data-city
value: Your Value

Then you could adjust your function:

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {
    // apply filter if loop has class: query-by-city
    if (! is_admin() && ! empty( $attributes['className'] ) && strpos( $attributes['className'], 'query-by-city' ) !== false) {
        $html_attributes = $attributes['htmlAttributes'];
        $city = '';

        foreach ( $html_attributes as $attribute ) {
            if ( 'data-city' === $attribute['attribute'] ) {
                $city = $attribute['value'];
            }
        }

        if ( ! $city ) {
            return $query_args;
        }

        $query_args = array_merge(
            $query_args,
            array(
                'meta_query' => array(
                    array(
                        'key' => 'city',
                        'value' => $city,
                        'compare' => '=',
                    )
                ),
            )
        );
    }

    return $query_args;
}, 10, 2 );
