如何通过ajax将数据数组发送到后端(php)

I need some help here guys, my issue is that the first console.log returns what has been built by the foreach, but the backend doesn't receive that same array. This foreach basically iterates over a table, looks for a certain id, makes it an index of an array, and then it fetches all the input values from the table and pushes it to that given index.

        var dateTime = [];
        $("#employeeData > tr").each(function(dateIndex, date) {
            dateTime[date.id] = [];
            $("#" + date.id + " :input").each(function(inputIndex, inputTime) {
                dateTime[date.id].push($(inputTime).val())
            });
        });
        var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');
        console.log(dateTime);
        $.post('employee',
            {
                dates: dateTime,
                _token: CSRF_TOKEN
            }, function(response) {
                console.log(response);
            }
        );
        });
    Route::post('/employee', 'EmployeesController@updateRecords');

    public function updateRecords(Request $request)
    {
        return $request->dates;
    }
    // this is a console.log of the dateTime, each date has 4 inputs 
    //associated with it
    [2017-11-02: Array(4), 2017-11-03: Array(4), 2017-11-06: Array(4), 2017- 
    11-07: Array(4), 2017-11-08: Array(4), …]

This all happens when jquery handles a click event.

    It is not possible to pass an array as it is in the post, it should be converted.

    Just encode your array as JSON string and decode it in the backend.

    var dateTime = [];
        $("#employeeData > tr").each(function(dateIndex, date) {
            dateTime[date.id] = [];
            $("#" + date.id + " :input").each(function(inputIndex, inputTime) {
                dateTime[date.id].push($(inputTime).val())
            });
        });
        var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');
        console.log(dateTime);
        var jsonString = JSON.stringify(dateTime);
        $.post('employee',
            {
                dates: jsonString,
                _token: CSRF_TOKEN
            }, function(response) {
                console.log(response);
            }
        );
        });
    

    in your PHP, decode the JSON string :

    $dates = json_decode(stripslashes($_POST['dates']));
