Returning data from php called via jQuery (ajax)

Question

I'm having trouble returning data from a php page.

test = function(data){
 alert(data);
}
newContent = function(var1){
 $.ajax({
 url: 'path/to/item.php&var1='+var1,
 success: function(data){
 test(data);
 }
 });
}

Which should return "Success" via echo 'Success!'; on the item.php page.

Why is it returning undefined?

Answer 1

Your URL is incorrect:

url: 'path/to/item.php&var1='+var1,

Use this instead:

url: 'path/to/item.php?var1='+var1,

Answer 2

In your item.php file, you need to echo the result. Something like this:

echo $data;

rather than:

return $data;

• Casey Dwayne: It is echo, as stated in OP. True return will not work for the ajax.
