Question

How would I get this to work?

$step = $_SERVER['PHP_SELF']. '?&step=';
echo "<form action=". $step ."2"><select>";

It’s giving me a (Parse error: syntax error, unexpected ‘<‘) on the second line. Halp?

Answer 1

Escape your quotes inside of strings:

echo "<form action=\"${step}2\"><select>";

That will fix your problem, but it would probably be a good idea to escape the attribute value before putting it in the HTML as well:

echo "<form action=\"" . htmlspecialchars($step) . "2\"><select>";
