Pass php variable via js/jquery redirect url function

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.

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'); });";

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.

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();

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

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);
}
