Invoice4U is an Israeli based service for creating invoices and receipts.
The documentation does not include an example of how to make the call using PHP.
Below is a short example of how to do so for the InvoiceReciept:Create call. I used the ConvertCharSet component to make the conversion from UTF-8 to windows-1255 (which is the encoding expected).
A note on mandatory fields: the 4 item fields (InvoiceItemCode, InvoiceItemDescription, InvoiceItemPrice, InvoiceItemQuantity) are mandatory. At the time of writing this post, this is not explicit in the documentation.
<?php
require_once 'ConvertCharset.class.php';
$cc=new ConvertCharset;
$current_encoding = 'UTF-8';
$new_encoding = 'windows-1255';
$data = '';
$data .= 'TransType=' . $cc->convert('IR:CREATE', $current_encoding, $new_encoding);
$data .= '&Username=' . $cc->convert('a4u_heb', $current_encoding, $new_encoding);
$data .= '&InvoiceSubject=' . $cc->convert('test', $current_encoding, $new_encoding);
$data .= '&InvoiceItemCode=' . $cc->convert('a1000001a', $current_encoding, $new_encoding);
$data .= '&InvoiceItemDescription=' . $cc->convert('description', $current_encoding, $new_encoding);
$data .= '&InvoiceItemQuantity=' . $cc->convert('1', $current_encoding, $new_encoding);
$data .= '&InvoiceItemPrice=' . $cc->convert('10', $current_encoding, $new_encoding);
$data .= '&CompanyInfo=' . $cc->convert('און בן-צבי', $current_encoding, $new_encoding);
$data .= '&MailTo=' . $cc->convert('onn.benzvi@gmail.com', $current_encoding, new_encoding);
$curl_url = 'https://www.invoice4u.co.il/public/HttpPost.aspx';
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, $curl_url);
curl_setopt($cURL, CURLOPT_SSL_VERIFYPEER, 0); // ignore ssl verification errors
curl_setopt($cURL, CURLOPT_SSL_VERIFYHOST, 0); // ignore ssl verification errors
curl_setopt($cURL, CURLOPT_HEADER, 1); // Don't return header info.
curl_setopt($cURL, CURLOPT_RETURNTRANSFER,1); // Return into a variable.
curl_setopt($cURL, CURLOPT_POST, 1);
curl_setopt($cURL, CURLOPT_POSTFIELDS, $data);//$pnp_post_values);
$val_from_curl = curl_exec($cURL);
?>
