Here is the code I use to create radio-buttons. On my database I have a table that saves the value of the radio-buttons. I got visual proof on the page that the the path is correct and I have also checked so $css gives the right value with the help of echo. The value I have is "style_default.css", but I only get the button for red selected. Anyone who knows where all this went wrong?

$css = "style_default.css"; //assumption
$stylesheet = array("style_default.css" => "Default", "style_red.css" => "Red");
foreach($stylesheet as $key => $value){
    echo '<input type="radio" name="style" value="'.$key.'" '; echo ($css == $key)? 'checked>' : '">'; echo $value.'<br/>';
}

The checked attribute accepts only checked and an empty string as its value. For example: checked="checked" or checked="" are correct.
