}, 'json');

PHP FILE

    if(!isset($_POST['workF'])){
    $_POST['workF'] ="undefine";
}

if(!isset($_POST['workP'])){
    $_POST['workP']="undefine";

}

if(!isset($_POST['gender'])){
    $_POST['gender']="undefine";
}

if(!isset($_POST['experince'])){
    $_POST['experince']="undefine";
}

if (!isset($_POST['jobs'])){
    $_POST['jobs']="undefine";
}

if(!isset($_POST['location'])){
    $_POST['location']="undefine";

}

$work_type_f = $_POST['workF'];
$work_type_p = $_POST['workP'];
$gender = $_POST['gender'];
$experince = $_POST['experince'];
$jobs = $_POST['jobs'];
$location =$_POST['location'];

all should be an object, not an array:

var all = {};

jQuery will do the necessary escaping for you when passing it to $.post, but it won’t read the object properties of an array.

However as Joy stated, you’re just trying to mimic a form here. Make sure the inputs are all contained inside a single form and use .serialize() to get a string which can be send along with a HTTP request.
