Ajax - 'ajax_url' => admin_url( 'admin-ajax.php' ) POST 400 (Bad Request).

[Obi-nine]

Hi,

I'm currently trying to use ajax with Oxygen builder, but I get POST 400 (Bad Request).

I have created a plugin to use as a function.php.

I'm using this code to use the PHP code, but Oxygen Builder seems to block the usage of admin-ajax.php.

"
wp_enqueue_script(
'cartajax',
plugin_dir_url( FILE ). 'assets/js/cartajax.js',
array('jquery','featherlight'),
false,
false
);
add_action( 'wp_ajax_nopriv_custom_price', 'custom_price' );
add_action( 'wp_ajax_custom_price', 'custom_price');

function custom_price() {
//require('price_algo.php');
//$rawData = file_get_contents("php://input");

//$signOptions = json_decode($rawData);

//$return = array("size"=>$signOptions->width*$signOptions->height, "price"=> getPrice($signOptions));
$return = array("size"=>200, "price"=> 300);

echo json_encode($return);

die();
}
wp_localize_script( 'cartajax', 'my_ajax_object',
array( 'ajax_url' => admin_url( 'admin-ajax.php' ) )
);
"
Has anyone had the same issue and found a solution to this?
I have searched everywhere but haven't been able to find a solution.

Thanks in advance!
