Mask credit card information in text box

[jebaraj]

I need to display Credit card number with only last 4 digits visible.The remaining numbers should display as **

eg: If the credit card number is 2222 1111 3333 4444

its should display as **** **** **** 4444 in a textbox

Can anybody provide me a solution

If you're looking to hide the number after it's been entered and submitted, you could use something like this:

 

<?php
$ccNum = "2222 1111 3333 4444";
print "<div>$ccNum</div>";
$ccNum_lastFour = substr($ccNum, -4);
$ccNum = preg_replace("~\d~", '*', $ccNum);
$ccNum = substr($ccNum, 0, -4) . $ccNum_lastFour;
print "<div>$ccNum</div>";
?>

 

 

If you're looking to hide the credit card as it's being typed into the form, you'll need to look into solution using a client-side option like JavaScript.
