Try using developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… on your data you are trying to send to the endpoint, because the string you are building to send may not be encoding theof the array

@Taplar the problem is more likely that they are trying to append an array to a string.

var quantity1 = document.getElementById("quiantitynice1").value; It gives you the error, because in your html code, JS engine does not find any id called "quiantitynice1" . And once if u get JS error it doesn't go for further processing.

@Taplar the problem is more likely that they are trying to append an array to a string.

var quantity1 = document.getElementById("quiantitynice1").value; It gives you the error, because in your html code, JS engine does not find any id called "quiantitynice1" . And once if u get JS error it doesn't go for further processing.

i solved the problem, in javascript the variable quantities , does not have the "var" and the php file is missing, but now it is more complex because the error that it says to me is: undefined, im going to edit the post
