I have this code that requests with Ajax for a PHP file. The problem is that you are only getting the input type="file" value, the other fields are not being passed to PHP.

I'm doing this to get the input value

var valor = $("input[name=nome]").val();
//mostra o valor com alert()
alert(valor);

How can I get all the form fields?

My js

$(document).ready(function() {

            $('.contato_form').validate({ // initialize the plugin
                rules: {
                    email: {
                        required: true,
                        email: true
                    },
                    nome: {
                        required: true,
                        minlength: 5
                    }
                },


                messages: {
                    required: "Campo obrigatório",
                    remote: "Please fix this field.",
                    email: "Por favor insira um email válido",
                    url: "Please enter a valid URL.",
                    date: "Please enter a valid date.",
                    dateISO: "Please enter a valid date (ISO).",
                    number: "Please enter a valid number.",
                    digits: "Please enter only digits.",
                    equalTo: "Please enter the same value again.",
                    maxlength: $.validator.format("Não insira mais do que {0} caracteres."),
                    minlength: $.validator.format("Digite pelo menos {0} caracteres."),
                    rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."),
                    range: $.validator.format("Please enter a value between {0} and {1}."),
                    max: $.validator.format("Please enter a value less than or equal to {0}."),
                    min: $.validator.format("Please enter a value greater than or equal to {0}."),
                    step: $.validator.format("Please enter a multiple of {0}.")
                },



                submitHandler: function(form) { // for demo
                    $(".resultado_contato_fom").html('<div class="spinner"></div>');
                    var form = $('.contato_form');

My PHP

if(isset($_FILES['file-upload']))
   {
      date_default_timezone_set("Brazil/East"); //Definindo timezone padrão

      $ext = strtolower(substr($_FILES['file-upload']['name'],-4)); //Pegando extensão do arquivo
      $new_name = date("Y.m.d-H.i.s") . $ext; //Definindo um novo nome para o arquivo
      $dir = $_SERVER['DOCUMENT_ROOT'].'wp-content/uploads/'; //Diretório para uploads

      move_uploaded_file($_FILES['file-upload']['tmp_name'], $dir.$new_name); //Fazer upload do arquivo
   }

Changing value in integer array in an index works in one case, and in another not, why? Forbidden 403 - City Hall Curitiba

The reason you're only getting the value of the input type="file", as you said, is because you're declaring a form, and putting only that variable in it:

var file_data = $('#file-upload').prop('files')[0];
var form_data = new FormData();
form_data.append('file-upload', file_data);

What you can do:

1 - Assign an id to your form: Example:

<form id="formSave" action="" method="post" class="contato_form" novalidate="novalidate" enctype="multipart/form-data">

2 - Next, structure your request as follows:

$('#formSave').validate({
    submitHandler: function (form) {
        $(form).ajaxSubmit({
            url: 'http://xxx.com.br/email_contato.php',
            type: 'post',
            resetForm: true,
            beforeSerialize: function () {

            },
            success: function () {

            }
        });
        return false;
    },
    rules: {
            // ...
    },
    messages: {
            // ...
    }
    });

Here is a generic routine of mine to give submit in all elements of the form

      var Elementos = {};
      function sendForm(){

        form = document.forms[0];
        for(var i=0; i<form.length; i++){
          Elementos[form.elements[i].name] = form.elements[i].value;
        }

        var xhr = new XMLHttpRequest();
        var url = 'http://localhost/DashboardMarketingPlace/produto/';
        xhr.open("GET", url, true);
        xhr.setRequestHeader("Content-type", "application/json");

        xhr.onreadystatechange = function () {
            if (xhr.readyState === 4 && xhr.status === 200) {
              // console.log('Resposta PHP: ' + xhr.responseText);
              document.getElementById('demo').innerHTML = xhr.responseText;
            }
        };

        var data = JSON.stringify('1');
        xhr.send(data);

      }
