View get-acf-sub-field-key-by-field-name-function.php
* Locates an ACF sub-field by field name and returns the sub-field's key.
* This is particularly useful if you need to construct a data array for programmatic field
* update where a complex field is in use (e.g; repeater, group, flexi).
* @param string $sub_field_name The sub field name we need a key for.
* @param array $field The ACF field array.

A basic example for querying data from custom tables created using ACF Custom Database Tables. For more info see

How to use your custom table data with WP_Object queries

This example illustrates how to query an array of post IDs from a custom DB table then use the array in a WP_Query.

This can be much faster than using meta queries on a WP_Query object, particularly if you are matching multiple fields.

You can’t perform that action at this time.
