PHP Example

This is an example of using the list_field_view call with PHP. You can replicate the same idea in virtually any other programming language. The example shown is using serialize as the output format. You can change that to XML or JSON if you would like.

<?php

// By default, this sample code is designed to get the result from your installation and print out the result
$url = 'http://account.api-us1.com';


$params = array(

    // the API Key can be found on the "Your Settings" page under the "API" tab.
    // replace this with your API Key
    'api_key'      => 'YOUR_API_KEY',

    // this is the action that fetches a list info based on the ID you provide
    'api_action'   => 'list_field_view',

    // define the type of output you wish to get back
    // possible values:
    // - 'xml'  :      you have to write your own XML parser
    // - 'json' :      data is returned in JSON format and can be decoded with
    //                 json_decode() function (included in PHP since 5.2.0)
    // - 'serialize' : data is returned in a serialized format and can be decoded with
    //                 a native unserialize() function
    'api_output'   => 'serialize',

    // ID(s) of the contact custom field(s) you wish to fetch - comma-separate for more than one
    // You can also pass the personalization tag here, IE: %PERS_7%
    'ids'           => '4',
);

// This section takes the input fields and converts them to the proper format
$query = "";
foreach( $params as $key => $value ) $query .= urlencode($key) . '=' . urlencode($value) . '&';
$query = rtrim($query, '& ');

// clean up the url
$url = rtrim($url, '/ ');

// This sample code uses the CURL library for php to establish a connection,
// submit your request, and show (print out) the response.
if ( !function_exists('curl_init') ) die('CURL not supported. (introduced in PHP 4.0.2)');

// If JSON is used, check if json_decode is present (PHP 5.2.0+)
if ( $params['api_output'] == 'json' && !function_exists('json_decode') ) {
    die('JSON not supported. (introduced in PHP 5.2.0)');
}

// define a final API request - GET
$api = $url . '/admin/api.php?' . $query;

$request = curl_init($api); // initiate curl object
curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response
curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
//curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment if you get no gateway response and are using HTTPS
curl_setopt($request, CURLOPT_FOLLOWLOCATION, true);

$response = (string)curl_exec($request); // execute curl fetch and store results in $response

// additional options may be required depending upon your server configuration
// you can find documentation on curl options at http://www.php.net/curl_setopt
curl_close($request); // close curl object

if ( !$response ) {
    die('Nothing was returned. Do you have a connection to Email Marketing server?');
}

// This line takes the response and breaks it into an array using:
// JSON decoder
//$result = json_decode($response);
// unserializer
$result = unserialize($response);
// XML parser...
// ...

// Result info that is always returned
echo 'Result: ' . ( $result['result_code'] ? 'SUCCESS' : 'FAILED' ) . '<br />';
echo 'Message: ' . $result['result_message'] . '<br />';

// The entire result printed out
echo 'The entire result printed out:<br />';
echo '<pre>';
print_r($result);
echo '</pre>';

// Raw response printed out
echo 'Raw response printed out:<br />';
echo '<pre>';
print_r($response);
echo '</pre>';

// API URL that returned the result
echo 'API URL that returned the result:<br />';
echo $api;?>
