It looks like your last line should be:

 

window.open("mydata.php?name=" + param + "&address=" + param2);

 

You may need to encode those values so they can be passed through the URL.  In mydata.php, you'd obtain those values by:

 

$name = $_GET['name'];
$address = $_GET['address'];

 

And, similarly, you may need to decode them here.

thank you for your help!!

 

I am still newbie with javascript...

i already did what has been written above

 

param = document.getElementById("Name").value

param2 = document.getElementById("address").value

    window.open("data.php?Name=" + param + "&address=" + param2);

  }

 

does it mean if i want to have another value such as telephone, i just add the parameter so it will looked like this

 

param = document.getElementById("Name").value

param2 = document.getElementById("address").value

param2 = document.getElementById("telephone").value

    window.open("data.php?Name=" + param + "&address=" + param2  + "&telephone=" + param3);  }

 

i've tried but it didn't work.....then how can i get value of the address with the same format like what written in the textbox.. in php i always use

 

nl2br($_GET['address']) but here didn't work

 

can help me solve this problem?

Hmm...more research has shown that JavaScript's encoding functions aren't compatible with PHP's encoding functions.  Thankfully, I've found a 3rd party function that works.

 

Here's the function:

 

function urlencode( str ) {

    var ret = (str+'').toString();
    
    var replacer = function(search, replace, str) {
        var tmp_arr = [];
        tmp_arr = str.split(search);

    for (unicodeStr in hash_map) {
        hexEscStr = hash_map[unicodeStr];
        ret = replacer(unicodeStr, hexEscStr, ret); // Custom replace. No regexing
    }
    
    // Uppercase for full PHP compatibility
    return ret.replace(/(\%([a-z0-9]{2}))/g, function(full, m1, m2) {
        return "%"+m2.toUpperCase();
    });
}

 

Once you have the definition in place, run all of your values through it.  So:

 

param = urlencode(document.getElementById('Name').value);

 

And so on.  Then, in your PHP, use:

 

$name = urldecode($_GET['Name']);
$address = nl2br(urldecode($_GET['address']);

 

Etc.
