How to fix an error with ajax request?

Question

PHP

Greetings. The third day I'm struggling with the problem, help me figure it out:
There is a self-written crm, there is a form on the site, I send the data from the form with a request:

var forma_array = form.serializeArray();
$.ajax({
  type: "POST",
  url: '/_iska2/action.php?actionType=RequestAjaxAction&method=createRequest',
  data: forma_array,
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(data) {
    console.log(data);
  },
  error: function(data){
    console.log(data);
  }
});

The data is received by the handler:

if ($_POST['last_name'] && $_POST['first_name'] && $_POST['type_id'] && $_POST['phone'] && $_POST['sum']) {
        ...
} else {
  print(json_encode(array('success' => false, 'sad' => print_r($_POST, true), 'message' => 'Не все поля заполнены!')));
}

And this is what I get in response from the handler:


The names of the fields are all correct, I suspect that the data comes to the handler in the wrong form, but I can’t understand what exactly ..

Answer 1

The serializeArray method returns not json, but an array of objects ( https://api.jquery.com/serializeArray/). Try turning forma_array into a json string with JSON.stringify and pass that string. The server probably crashes when trying to read json which is not actually json

Answer 2

I have $(form).serialize(); works well
(Without Array)
