How to return value using ajax
- by Priyanka
Hello.
I have Ajax file in which code has written to accept values form user and then these values are taken in a Ajax function as follows:
$(document).ready(function(){
$("#newsletterform").validate();
$('#Submit').click(function(){
var name = $('#newsletter_name').val();
var email = $('#newsletter_email').val();
sendValue(email,name);
});
});
The function for paasing values and getting values from other file:
function sendValue(str,name){
$.post(
"newsletter/subscribe.php", //Ajax file
{ sendValue: str,
sendVal: name
},
function(data2){
$('#display').html(data2.returnValue);
},
//How you want the data formated when it is returned from the server.
"json"
);
}
and these values are passed to another file called "subscribe.php" in which insertion code to database is written and again I return the value to my first ajax function as follows:
echo json_encode(array("returnValue"=$msg));
The msg is ging to contain my message to be displayed.
But now, this works fine on localhost, I get the return values nad message properly but when I upload it on server this gives me an error as:
data2 is null
[Break on this error] $('#display').html(data2.returnValue);
This only gives error for return value but insertion, sending mail functionality works fine.
Please provide me with a good solution wherein I can be able to get back the return values without any error.
Thanks in advance.
