How to get "metric" and "element" names for PHP - Adobe Analytics - php

Question

I am pulling a report using the Adobe API from Omniture.
Here is the full script :
<?php
include_once('/path/SimpleRestClient.php');
// Date
$end_date = date("Y-m-d",strtotime("-1 days"));
$start_date = date("Y-m-d",strtotime("-8 days"));
// Location of the files exported
$adobe_file = '/path/Adobe_'.$end_date.'.csv';
// List creation that will be updated with the fields and be put into my CSV file
$list = array
(
array('lasttouchchannel', 'product','visits','CTR(Clicks/PageViews)') // headers // ADD or DELETE metrics #
);
function GetAPIData($method, $data)
{
$username = "XXXX";
$shared_secret = "XXXX";
$postURL = "https://api3.omniture.com/admin/1.4/rest/?method=";
// Nonce is a simple unique id to each call to prevent MITM attacks.
$nonce = md5(uniqid(php_uname('n'), true));
// The current timestamp in ISO-8601 format
$nonce_ts = date('c');
/* The Password digest is a concatenation of the nonce, it is timestamp and your password
(from the same location as your username) which runs through SHA1 and then through a base64 encoding */
$digest = base64_encode(sha1($nonce . $nonce_ts . $shared_secret));
$rc = new SimpleRestClient();
$rc -> setOption(CURLOPT_HTTPHEADER, array("X-WSSE: UsernameToken Username=\"$username\", PasswordDigest=\"$digest\", Nonce=\"$nonce\", Created=\"$nonce_ts\""));
//var_dump($o);
$rc -> postWebRequest($postURL .$method, $data);
return $rc;
}
$method = 'Report.Queue';
$data ='
{
"reportDescription":
{
"reportSuiteID":"XXXX",
"dateFrom":"'.$start_date.'",
"dateTo":"'.$end_date.'",
"metrics":[{"id":"visits"},{"id":"instances"},{"id":"pageviews"}],
"elements":[{"id":"lasttouchchannel","top":"50000"}]
}
}';
/*
"date":"'.$date.'",
"dateTo":"'.$date.'",
"dateFrom":"'.$start_date.'",
"dateTo":"'.$end_date.'",
*/
$rc=GetAPIData($method, $data);
if($rc -> getStatusCode() == 200) // status code 200 is for 'ok'
{
$counter = 0;
do
{
if($counter>0){sleep($sleep = 120);}
$return = GetAPIData('Report.Get', $rc->getWebResponse());
$counter++;
}while($return -> getStatusCode() == 400 && json_decode($return->getWebResponse())->error == 'report_not_ready'); // status code 400 is for 'bad request'
//
$json=json_decode($return->getWebResponse());
foreach ($json->report->data as $el)
{
echo $el->name.":".$el->counts[0].":".$el->counts[1]."\n";
// Adding the data in the CSV file without overwriting the previous data
array_push($list, array($el->name, $el->name, $el->counts[0], ($el->counts[1])/($el->counts[2])));
}
}
else
{
echo "Wrong";
}
$fp = fopen($adobe_file, 'w');
foreach ($list as $fields)
{
// Save the data into a CSV file
fputcsv($fp, $fields);
}
fclose($fp);
?>
How can I get the names of the metrics and elements in order to use them in this script? There is no way. I searched with all the possible tags on google and nothing worked !
I need the metrics and elements for this part of the code :
$data ='
{
"reportDescription":
{
"reportSuiteID":"XXXX",
"dateFrom":"'.$start_date.'",
"dateTo":"'.$end_date.'",
"metrics":[{"id":"visits"},{"id":"instances"},{"id":"pageviews"}],
"elements":[{"id":"lasttouchchannel","top":"50000"}]
}
}';
I cannot find 'date' as an element which is crucial. I cannot find all the other metrics as well. In Google Analytics we had this link :
Google Analytics Query
but in Adobe there is not any. I want something like that :
"metrics":[{"id":"instances"},{"id":"impressions"}],
"elements":[{"id":"date","top":"50000"}]

You would json_decode() as $data contains a JSON string. For example:
$data ='
{
"reportDescription":
{
"reportSuiteID":"XXXX",
"dateFrom":"'.$start_date.'",
"dateTo":"'.$end_date.'",
"metrics":[{"id":"visits"},{"id":"instances"},{"id":"pageviews"}],
"elements":[{"id":"lasttouchchannel","top":"50000"}]
}
}';
$json = json_decode($data, true);
echo $json['reportDescription']['dateFrom'];
print_r($json['reportDescription']['metrics']);
