Hello, i've try to integrate a hook function but not work: <?php function customAfterInvoicingHook($vars) { $invoiceId = $vars['invoiceid']; $invoiceDetails = localAPI('GetInvoice', array('invoiceid' => $invoiceId)); $xmlContent = '<?xml version="1.0" encoding="UTF-8"?>'; $xmlContent .= '<invoice>'; $xmlContent .= '<invoice_id>' . $invoiceDetails['id'] . '</invoice_id>'; $xmlContent .= '<client_id>' . $invoiceDetails['userid'] . '</client_id>'; $xmlContent .= '</invoice>'; $xmlFilePath = '/fatture/' . $invoiceId . '.xml'; file_put_contents($xmlFilePath, $xmlContent); } add_hook('AfterInvoicingGenerateInvoiceItems', 1, 'customAfterInvoicingHook') I put this inside /includes/hooks/custom_invoice_hook.php but when i generate invoice nothing append, no file generated, no error in the server log, can you help to fix that? Have nice day
