PHP Fatal error: Call to undefined function how do I fix it?

PHP

I’ve very new to PHP and am trying to get API (REST) to work with a site I’m currently working on. It works if I submit a form using AJAX but I want it to work without using AJAX. The code I’m using is:

<?php
$postContactUrl = 'https://apiconnector.com/v2/contacts/';
$data = array(
'Email' => $_POST['email'],
'EmailType' => 'Html',
'dataFields' => array(
array(
'Key' => 'FULLNAME',
'Value' => $_POST['name_first']." ".$_POST['name_last'] ),
)
);
$contact = execute_post($postContactUrl, $data);

$addContactToAddressBookUrl = 'https://apiconnector.com/v2/address-books/' . '123456' . '/contacts';
$book =  execute_post($addContactToAddressBookUrl, $contact);

function execute_post($url, $data){
$requestBody = json_encode($data, true);

$ch = curl_init();

curl_setopt($ch, CURLAUTH_BASIC, CURLAUTH_DIGEST);
curl_setopt($ch, CURLOPT_USERPWD, 'username' . ':' . 'password');
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestBody);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array ('Accept: ' . 'application/json' ,'Content-Type: application/json'));

$responseBody = json_decode(curl_exec($ch));

curl_close($ch);

return $responseBody;
}
?>

but when I try to add that to the page the form is on I get this error:

PHP Fatal error: Call to undefined function execute_post()
I’ve tried to fix it but nothing I do seems to work. I don’t understand why it works with AJAX but not any other way.

I tried moving the function to before I called it but neither this:

function execute_post(){
...
}

    $contact = execute_post($postContactUrl, $data);

nor this worked:

function execute_post(){

    $contact = execute_post($postContactUrl, $data);

Should this line have a comma on the end? I can’t see why it needs one, it implies there’s another parameter coming but there isn’t. Could it just be upsetting the parser?

'Value' => $_POST['name_first']." ".$_POST['name_last'] ),

I did try it without the comma but that didn’t make a difference, I’ve attached the file with the full code but I’m really at a loss as to why I keep getting the fatal error.

The only time I don’t get it is if I move the function to above where it’s called, but then the when I do that it’s not called at all.
:confounded:
REST.php (13.7 KB)

I think I have have discovered where the problem is. When I use print_r on $data it prints the results, $contact again works but $book prints nothing at all. I don’t know what the reason for $book not showing anything. I tried renaming it incase it was conflicting with something I wasn’t aware of but that didn’t make any difference.

Does anybody have any suggestion as to why this isn’t working?
