The Problem:
User is unable to send Google Analytics 4 (GA4) events from the server side using PHP. The code snippet in JavaScript works fine, but the PHP code snippet doesn’t send the event to GA4 and doesn’t return an error message either.
The Solutions:
Solution 1: Correcting PHP Server-Side GA4 Event Sending
The provided PHP code to send GA4 events from the server encounters several issues that prevent successful event transmission:
- Incorrect Event Format: The
events
array should be an array of objects, each containingname
andparams
properties. It should be structured like this:
'events' => [
['name' => 'form_submission', 'params' => ['form_name' => '', 'is_lead' => '', 'submission_url' => '']]
]
-
Incorrect Content-Type: The
Content-type
header should be set toapplication/json
because the request body is in JSON format. -
Improper Data Encoding: The
http_build_query()
function, used to encode the data, is not suitable for JSON data. Usejson_encode()
instead.
Here’s the corrected PHP code:
$measurement_id = 'G-XXXXXXXXXX';
$api_secret = 'api_secret_key';
$url = "https://www.google-analytics.com/mp/collect?measurement_id=$measurement_id&api_secret=$api_secret";
$data = [
'client_id' => '1552776741.1677766660',
'events' => [
['name' => 'form_submission',
'params' => [
'form_name' => 'Send A Message 2',
'is_lead' => 'Non-Lead Submission',
'submission_url' => 'Unknown'
]
]
]
];
$options = [
'http' => [
'header' => "Content-type: application/json",
'method' => 'POST',
'content' => json_encode($data)
]
];
$context = stream_context_create($options);
$resp = file_get_contents($url, false, $context);
// Handle response as needed
Ensure you replace G-XXXXXXXXXX
with your actual measurement ID and api_secret_key
with your API secret key.
Q&A
What mistakes are in the php code that prevents data from being sent to GA4?
The ‘events’ array should be wrapped in an object, the content-type header should be ‘application/json’ and data should be json_encoded.
Why is http_build_query
is not suitable to encode the data?
It should be encoded as JSON instead. You can use json_encode()
.
