How to get array data passed by .post in jquery into php?

Question

I have a problem regarding on how to get the value of the array variable passed by .post in jquery into my php page

this is my jquery code:

minDate = [];
hoursWork = [];
empId = [];
        $('.minDate').each(function() { 
            minDate.push($(this).val());
        });

        $('.hoursWork').each(function() { 
            hoursWork.push($(this).val());
        });

        $('.empId').each(function() { 
            empId.push($(this).val());
        });

            $.post('rtInsert.php', { minDate: minDate, hoursWork: hoursWork, empId: empId }, function(data) { 
        alert(data);
    });

How can I get the passed data in my rtInsert.php

i tried

$minDate = $_POST['minDate'];
$empId = $_POST['empId'];
$workHours = $_POST['hoursWork'];

now how will i get the individual value of the array because all the 3 variables is an array

All I know is a single array using foreach() but what if there are 3 arrays passed

Is there any idea how I can get it or how can I passed into single array.

Thanks in Advance.

If you can't use $_POST['blah'], try file_get_contents("php://input") — Alvin Wong

You can use the JSON.stringify(data); to turn them into JSON and prase it on the server side as this; $data = json_decode($json);.

Your code will then become this:

var minDate = [];
var hoursWork = [];
var empId = [];
$('.minDate').each(function() { 
    minDate.push($(this).val());
});

$('.hoursWork').each(function() { 
    hoursWork.push($(this).val());
});

$('.empId').each(function() { 
    empId.push($(this).val());
});

$.post('rtInsert.php', { minDate: JSON.stringify(minDate), hoursWork: JSON.stringify(hoursWork), empId: JSON.stringify(empId) }, function(data) { 
    alert(data);
});

And your server side ccode:

<?php
$mindate = json_decode($_POST['minDate']);
$hourswork = json_decode($_POST['hoursWork']);
$empid = json_decode($_POST['empId']);
foreach($mindate as $k=>$val)
{
    $date = $val;
    $work =$hourswork[$k];
    $id =$empid[$k];
    //...
}
?>
