yes all the code snippets work

right now user inputs address and clicks submit and the input(address) is put into mysql


also the code for verifying if btc address is valid works

however i cant figure outhow to put this together into a working project


this is from the checkAddress function

the address variable is empty

  $address = "";
$eth = mysqli_real_escape_string($conn,$_POST['address']);

so i dont know what to use here- do i need to change this to

$address = $eth;




$eth is actually $btc
