*/
function chatgpt_response($user_message) {
$api_key = 'your_openai_api_key';

$data = [
'model' => 'gpt-4',
'messages' => [['role' => 'user', 'content' => $user_message]],
'temperature' => 0.7
];
$options = [
'http' => [
'header' => "Content-type: application/json\r\nAuthorization: Bearer $api_key\r\n",
'method' => 'POST',
'content' => json_encode($data),
]
];
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return json_decode($result, true)['choices'][0]['message']['content'];
}
?>2. Create a Shortcode to Display the Chatbot
Add this function to your theme’s functions.php file:
function chatgpt_chatbox() {
return '<div id="chatgpt-box">
<input type="text" id="chat-input" placeholder="Ask me anything...">
<button id="send-button">Send</button>
<div id="chat-response"></div>
</div>
<script>
document.getElementById("send-button").addEventListener("click", function() {
var userMessage = document.getElementById("chat-input").value;
fetch("/wp-admin/admin-ajax.php?action=chatgpt_response&message=" + userMessage)
.then(response => response.text())
.then(data => {
document.getElementById("chat-response").innerHTML = data;
});
});
</script>';
}
add_shortcode('chatgpt', 'chatgpt_chatbox');3. Display the ChatGPT Chatbox on Your Website
