jQuery form doesn't send

Answer 1

Change it as follows:

url: "http://www.cherrytrees.nl/tmp/process.php?" + data,

In your original request you were sending it via POST, rather than GET.

Answer 2

 url: "http://www.cherrytrees.nl/tmp/process.php", 
       type: "GET",    
       data: data,  

the option "data" ist only for POST type, if you wont to GET paratmeeters, write them in your URL

url.com?name="+$("#name").val()+"&gende....

Answer 3

maybe this will help:

   success: function(result){
    $("#content").html(result);
   }

In your code you are sending 2 ajax request. First with $.ajax and with some GET parameters, and second with $().load, but without any parameters. So actually you can simplify your code to this:

if(form == true){
   var gender = $("input[@name='rgender']:checked").val();
   var data = "name="+$("#name").val()+"&gender="+gender+"&country="+$("#country").val()+"&address="+$("#address").val()+"&zip="+$("#zip").val()+"&city="+$("#city").val()+"&mail="+$("#mail").val()+"&phone="+$("#phone").val()+"&checkin="+$("#checkin").val()+"&guests="+$("#guests").val()+"&time="+$("#time").val()+"&nights="+$("#nights").val()+"&remarks="+$("#remarks").val();
   $("#content").load('http://www.cherrytrees.nl/tmp/process.php', data);
   f.preventDefault();
}
