使用JQuery将JSON数据从Javascript传递到PHP

Question

I want to pass json data from my Javascript script to the PHP one and I am kinda struggling with it.

First here is the code:

var d = new Date(),
    DayOfWeek = d.getDay(),
    Actual_Day = d.getDate(),
    Month = d.getMonth() + 1;
if (Month < 10) {
    Month = '0' + Month;
}
var Year = d.getFullYear();
var Date = Year.toString() + Month.toString() + Day.toString();
var Hour = d.getHours(),
    Minutes = d.getMinutes();

var data = {
    "YearKey": Year,
    "MonthKey": Month,
    "Actual_DayKey": Actual_Day,
    "DayOfWeekKey": DayOfWeek,
    "DateKey": Date,
    "HourKey": Hour,
    "MinutesKey": Minutes

};

jQuery.ajax({
    type: "POST",
    url: 'index.php',
    type: 'json',
    data: data,
    success: function(data) {
        console.log('success!');

    }
});

In my PHP script, I've tried to be sure that I have a value but it seems to not be the case:

if (isset($_POST['YearKey'])) {echo $_POST['YearKey']; exit();}

Any solutions, advices would be appreciated!

Answer 1

In your jQuery , type:ajax means you prepare the function to an ajax response

in your case you need to send a JSON

put that line in your client code

data: {data:JSON.stringify(data)}
// will send the JSON string with the request in a parameter called data

on your server decode it

<?php
$data = json_decode($_POST['data']);

Answer 2

It's actually quite simple. In order to pass variables through to your PHP file from your AJAX request, you need to edit the URL portion of the request. For example, if your url looks like this:

url: "name_of_file.php/?value=VARIABLE-STUFF&more=VARIABLE-STUFF&etc=etc"

The variable values of value, more, and etc will be accessible in your PHP file. Then use:

$variable_name = $_GET['value'];

to store the variable 'value' into 'variable_name' for use in PHP file, and etc for any other variables you pass to the PHP file. For your case, I would suggest just passing the entire data object into the PHP file and working from there.

url: "index.php/?object=" + data

Then in PHP file do:

$object_name = $_GET['object'];

Now, your data object in your HTML file will be usable in your PHP file under the variable $object_name.

Answer 3

file_get_contents(php://input) 

gets the raw POST data like JSON object that cannot be decoded to $_POST.

<?php
$data = var_dump(file_get_content('php://input'));

Answer 4

you need to check all posted data having values or not

so please check with console.log(data); .

i think it may help you .
