Plugin usage

Plugin expects $xml_string parameter to be passed. It should contain the contents of the XML file that is produced by ACF plugin upon export of an ACF field.

To insert more than one field (a clone) with the same title, you should pass true as a second parameter.

Sample code (to be used in, for example, theme's functions.php file):

$acf_import = WP_ACF_Importer::get_instance();

$acf_field = file_get_contents('advanced-custom-field-export.xml');

if( $acf_import->acf_create_field( $acf_field) ) {
    echo 'Field created successfully.';
}
else {
    echo 'Import has not been performed.';
}
