How can I make get_field to work as well with dynamic filtering as get_post_meta do in the code example below? I’m working with third-party code that uses get_field to fetch values and I can’t modify that code so I need get_field to get along with the dynamic filtering. I’ve also tried using the acf/load_value filter but it was to no avail.
I’ve a post with ID 89 and an ACF field named “test_text_field” with the value “This text is stored in the ACF field.”.
add_action( 'wp_footer', function() {
add_filter( 'get_post_metadata', 'filter_get_post_metadata', 10, 5 );
echo 'Step 1 - Filter added: ' . get_post_meta( 89, 'test_text_field', true ) . '<br>';
echo 'Step 1 - get_field: ' . get_field( 'test_text_field', 89 ) . '<br>';
remove_filter( 'get_post_metadata', 'filter_get_post_metadata', 10, 5 );
echo 'Step 2 - Filter removed: ' . get_post_meta( 89, 'test_text_field', true ) . '<br>';
echo 'Step 2 - get_field: ' . get_field( 'test_text_field', 89 ) . '<br>';
add_filter( 'get_post_metadata', 'filter_get_post_metadata', 10, 5 );
echo 'Step 3 - Filter added: ' . get_post_meta( 89, 'test_text_field', true ) . '<br>';
echo 'Step 3 - get_field: ' . get_field( 'test_text_field', 89 ) . '<br>';
} );
function filter_get_post_metadata( $value, $object_id, $meta_key, $single, $meta_type ) {
if ( 'test_text_field' === $meta_key ) {
$value = array( microtime() );
}
return $value;
}
Output:
Step 1 - Filter added: 0.47892500 1659789061
Step 1 - get_field: 0.47922900 1659789061
Step 2 - Filter removed: This text is stored in the ACF field.
Step 2 - get_field: 0.47922900 1659789061
Step 3 - Filter added: 0.47933000 1659789061
Step 3 - get_field: 0.47922900 1659789061
Thankful for any ideas on how to get the dynamic filtering working with get_field.
