为什么表单数据没有使用serializeArray（）接收表单字段

Question

我不知道为什么表单字段没有通过serializeAll()函数提取，也没有到达被调用的php页面。

print_r($_FILES)                 // brings me data.

print_r($_POST/$_REQUEST/$_GET)  // brings me NO data.

JS / JQuery （数据操作）

var fd = new FormData();

var other_data = $('#includeExamform').serializeArray();
$.each(other_data,function(key,input){
    fd.append(input.name,input.value);
});

var file_data = $('input[type="file"]')[0].files; // for multiple files
for(var i = 0;i<file_data.length;i++){
    fd.append("file_"+i, file_data[i]);
}
$.ajax({
        type: "POST",
        url: caminho+"/view/cadastroExame.php?acao=salvar",
        timeout: 20000,
//      enctype: 'multipart/form-data',
        processData: false,
        contentType: false,
        data: fd,
        success: 
            function(data){
                if(jQuery.trim(data) == 'ok'){
                    alert('Sucess!');
                    $("#includeExamform")[0].reset();
                    $("#select-patient").html('Paciente: <button class="btn     btn-theme btn-search margintop10 pull-left" type="button" onCLick="popupCenter(\'selecionaPaciente.php\', \'selecionaPaciente\', 750, 500);" >Pesquisar</button>');
//                  window.location = caminho+"/view/cadastroFornecedor.php";
                }
                else{
                    alert('Exam already registered!');
                }
            }
    });
}

PHP （测试我执行并且没有表单字段数据）

print_r($_FILES);
print_r($_POST);
print_r($_REQUEST);
print_r($_GET);

if ( 0 < $_FILES['file']['error'] ) {
   echo 'Error: ' . $_FILES['file']['error'] . '<br>';
} else {
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
}

网络浏览器控制台 （结果）

    [file_0] => Array
