[Help] Need to edit existing code to include Image

[avinashpudota]

Hi,
I have an existing code which takes input from a form submission and sends to WhatsApp. Now i need to include image uploaded via the same form.

Below is the existing code, can anyone please help me to attach image to it. Variable name for image is "Cake_Image" and it is received as URL in form.
I have checked in #230 which says to use /send/image but i am unable to do it. And also i have checked API documentation but i didn't find any relevant sample code.

<?php
// Capture raw input
$rawPostData = file_get_contents("php://input");
parse_str($rawPostData, $formData); // Convert encoded data to array

// Log raw input for debugging
//file_put_contents("debug.log", date("Y-m-d H:i:s") . " - Raw Input: " . $rawPostData . "\n", FILE_APPEND);
//file_put_contents("debug.log", date("Y-m-d H:i:s") . " - Parsed Form Data: " . print_r($formData, true) . "\n", FILE_APPEND);

// Remove unnecessary fields
unset($formData['form_id'], $formData['form_name']); 

// Extract phone number
$phone = $formData['Customer_Number'] ?? "";
if (empty($phone)) {
    file_put_contents("error.log", date("Y-m-d H:i:s") . " - Validation Error: Customer_Number is missing\n", FILE_APPEND);
    echo json_encode(["status" => "error", "message" => "Customer Number is required"]);
    exit;
}


// Format message with all fields
$message = "New Cake Order:\n";
foreach ($formData as $fieldName => $fieldValue) {
    if (!empty($fieldValue)) { // Skip empty fields
        $formattedFieldName = str_replace(["_", "/"], " ", $fieldName); // Clean field names
        $message .= "*{$formattedFieldName}:* {$fieldValue}\n";
    }
}

// API Endpoint
$apiUrl = "http://xx.xx.xx.xx:3000/send/message";

// List of phone numbers (customer's number + shop owner number)
$phoneNumbers = [
    $phone . "@s.whatsapp.net",
    "xxxxxxxxxx@s.whatsapp.net"
];

// Send message to each phone number
foreach ($phoneNumbers as $recipient) {
    // Generate a unique message ID for each recipient
    $replyMessageId = strtoupper(uniqid());
    
    $data = [
        "phone" => $recipient,
        "message" => $message,
        "reply_message_id" => $replyMessageId
    ];

    // Send data via cURL
    $ch = curl_init($apiUrl);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: application/json"]);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Capture API response
    $response = curl_exec($ch);
    curl_close($ch);

    // Log response
    $logFile = "response.log";
    $logData = date("Y-m-d H:i:s") . " - Request: " . json_encode($data) . " - Response: " . $response . "\n";
    file_put_contents($logFile, $logData, FILE_APPEND);
}

// Return success response
header('Content-Type: application/json');
echo json_encode(["status" => "success", "message" => "Message sent to both numbers"]);
?>
