Code Example:
<?php $xml_string = ""; $xml_string = "<?xml version=\"1.0\" ?>"; $xml_string .= "<AccessRequest xml:lang=\"en-US\">"; $xml_string .= "<AccessLicenseNumber>LICENCE_NUMBER</AccessLicenseNumber>"; $xml_string .= "<UserId>USER_ID</UserId>"; $xml_string .= "<Password>PASSWORD</Password>"; $xml_string .= "</AccessRequest>"; $xml_string .= "<?xml version=\"1.0\" ?>"; $xml_string .= "<AddressValidationRequest xml:lang=\"en-US\">"; $xml_string .= "<Request>"; $xml_string .= "<TransactionReference>"; $xml_string .= "<CustomerContext>Address Validation Request</CustomerContext>"; $xml_string .= "<XpciVersion>1.0001</XpciVersion>"; $xml_string .= "</TransactionReference>"; $xml_string .= "<RequestAction>AV</RequestAction>"; $xml_string .= "</Request>"; $xml_string .= "<Address>"; $xml_string .= "<CountryCode>US</CountryCode>"; $xml_string .= "<City>Escondido</City>"; $xml_string .= "<State>CA</State>"; $xml_string .= "<PostalCode>92082</PostalCode>"; $xml_string .= "</Address>"; $xml_string .= "</AddressValidationRequest>"; $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL,"https://onlinetools.ups.com/ups.app/xml/AV"); /// the url to post to without the ?query+string curl_setopt ($ch, CURLOPT_HEADER, 0); /// header control curl_setopt($ch, CURLOPT_POST, 1); // tell curl to do a POST, not a GET curl_setopt($ch, CURLOPT_VERBOSE, 1); // tell curl to do a verbose curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // tell curl to do a verbose curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_string); /// the query string goes here as set in the variable above curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); /// allows it to set the response in a variable - $xyz curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml;')); /// allows it to set the response in a variable - $xyz $myresult = curl_exec ($ch); /// execute the curl session and store the response in the variable $xyz curl_close ($ch); /// close the curl session echo htmlentities($myresult); ?>
