Call to undefined function

  • I am trying to create a click counter. So, I have created a ajax call to counter.php, where the incrementing functions will take place.

    After incrementing, I wanted to update a custom field. So, I tried to use some acf field functions. But, I get an error, Uncaught Error: Call to undefined function the_field()

    Here is the entire code.

    <?php
$currentNumber = $_POST['currentNumber'];
$postId = $_POST['postId'];

function increment($currentNumber) {
    $newNumber = $currentNumber + 1;
    return $newNumber;
}

echo increment($currentNumber);
 
?>
<p></p>
<?php echo $postId ?>
<?php the_field( 'coupon_users' ); ?>

    How to solve this error?
