带有传递值的重定向页面

Question

I have a real problem and it's syntax problem. Normally when I need redirect any page I just use header function. Sometimes I use a variable when I need like below:

if(condition) header("Location: home.php?wrong=1");

Sometimes it could be:

if(condition) header("Location: home.php?wrong=1&&success=2");

There is no problem with direct use of variable(wrong or success). And when I need redirect a value from html form via post method, I use this code and it works:

if (condition) header("Location: home.php?id=".$_POST['topic_id']);

But I need more, I need pass another value too. So I use:

if (condition) header("Location: home.php?id=".$_POST['topic_id']&&wrong=1);

And this time I become a dumb. Can anyone help me out by providing proper syntax? I just need pass the WRONG=1 part too.

Answer 1

you need:

if (condition) header("Location: home.php?id=" . $_POST['topic_id'] . "&wrong=1");

or

if (condition) header("Location: home.php?id={$_POST['topic_id']}&wrong=1");
