Pass php variable via js/jquery redirect url function

Question

In my php i'd like to redirect via javascript/jquery a url with a php variable via js function.

My js function

function Redirect(url){
  document.location.href=url;
}

In my php page i try in this way but I fear there is a problem with the syntax in the $url.

if ($opz = 1){

  $url = "index.php?opz=OK#PG2&id=" . $_GET['id'];

  echo "<script>";
  echo "$(function(){ Redirect($url); });";
  echo "</script>";
}

If I try to redirect in this way everything works perfectly (no Redirect function).

echo "<script>
          document.location.href='index.php?opz=OK#PG2&id=$_GET[id]'
      </script>";

Can anyone suggest me what is the correct syntax to pass my php variable via the js Redirect function? Thanks.

Have a look at the generated HTML and learn how to debug JavaScript. — Felix Kling

Just change echo "$(function(){ Redirect($url); });"; to

echo "$(function(){ Redirect('$url'); });";

Notice the quotes. the url is to be passed to the Redirect function as a string. So enclose it in single quotes. like Redirect('$url');

your problem is simple:

  echo "$(function(){ Redirect($url); });";

should be replaced with

  echo "$(function(){ Redirect('$url'); });";

Why you are trying to redirect your webpage using javascript.

You can do it with PHP also. Use PHP header() function to redirect your page.

if ($opz = 1){

  $url = "index.php?opz=OK#PG2&id=" . $_GET['id'];

  header("Location:".$url);
}

Assuming the Javascript code being generated is OK try window.location

try like below

if ($opz = 1){
 $param = 'opz='.urlencode("OK#PG2").'&id='.$_GET['id'];

$url = "index.php?".$param;

echo "<script>";
echo "$(function(){ Redirect($url); });";
echo "</script>";
}

and pick up opz using urldecode();

The problem is caused by the fact that your generated HTML looks like this:

Redirect(index.php?opz=.....);

As you can see, you're missing quotes.

To put a variable from PHP into JavaScript, I always use json_encode. This ensures that, no matter what I pass it, JavaScript will see the same thing. It takes care of quoting, escaping, even iterating over arrays and objects.
