Written by The following will allow for you to post PHP in your widgets:
Place in your functions.php file
Appearance > Editor > Theme Functions (functions.php)
add_filter('widget_text', 'php_text', 99);
function php_text($text) {
if (strpos($text, '<' . '?') !== false) {
ob_start();
eval('?' . '>' . $text);
$text = ob_get_contents();
ob_end_clean();
}
return $text;
}
Now you can place php code so long as its within its <?php and ?> tags.
