Question

I have two set of radio buttons in html form button and button1. I am using below code to

1.keep the default value checked (

Answer 1

I had a similar problem recently, but had a lot more radio buttons to deal with, so I thought I'd abstract away the value checking functionality into a method that also creates the radio button itself, therefore minimising repetitive value-checking code. I've reworked mine to suit your variable names:

function createRadioOption($name, $value, $onClickMethodName, $labelText) {

  $checked = '';
  if ((isset($_POST[$name]) && $_POST[$name] == $value)) {
    $checked = ' checked="checked"';
  }

  echo(''. $labelText .'');
}
