Answer 1

I am adding sample code to give you an idea, how you could use AJAX Call with it.
<?php
if(mysql_num_rows($runzz)==0){
echo "<p align='center'><font size='5'>This Item $code1 - $code2 - ".$rw2['description']. "</br></br> Doesn't Exist In The <u><b>".$rowto['name']."</b></u></br></br> Wanna Add IT ?</font></p>";
?>
<script>
function check(){
var r = confirm("Press a button!");
if(r) {
// Add additional parameter
// You could use POST method too. Use whatever make sense to you.
var urlLink = 'http://www.example.com/warehouse/record.php?from=<?php echo $from?>&to=<?php echo $to?>';
$.ajax({
type: 'GET',
url: urlLink,
success: function(data) {
if(data == 'success') {
return 'You have successfully added new record!';
}
},
error: function(data) {
console.log(data);
}
});
} else {
return false;
}
}
check();
</script>
<?php } ?>
<?php
// -- New File: record.php File
//
// You might wanna add the check, that it's the legit request and all the PHP Validation
$form = $_GET['from'];
$to = $_GET['to'];
$qty = $_GET['qty'];
$codeid = $_GET['codeid'];
$uid = $_GET['uid'];
$insert="INSERT INTO transfercopy(warehouseidfrom,warehouseidto,qty,itemid,uid)VALUES('$from','$to','$qty','$codeid','$uid')";
$run=mysql_query($insert,$con);
if(!$run) die("error".mysql_error());
else return 'success';
?>
