Question

I have a script that calls another php page and passes values using PHP get.

The one variable, q is sent with the URL where str is a variable.

xmlhttp.open("GET","getdata.php?q="+str,true); 

I have a few multiple variables that I want to send in the URL string.

How can I send multiple variables.

Along the lines of:

xmlhttp.open("GET","getdata.php?q="+str+"y="+str2+"z="+str3,true); 

where the URL will then be somthing like

page.php?q=Peter&y=John&z=Smith

Answer 1

You’ll need to separate them with an ampersand, and probably URL-encode them too:

xmlhttp.open("GET","getdata.php?"
    + "q=" + encodeURIComponent(str)
   + "&y=" + encodeURIComponent(str2)
   + "&z=" + encodeURIComponent(str3), true);

Also, no problem 😉
