Javascript HTTP-EQUIV似乎不起作用

Question

I would like to redirect a page with two defined variables in Javascript:

if(isset($_POST['action'])){
        $task = $_POST['tasks'];
        $brand = $_POST['brands'];
        echo "<META HTTP-EQUIV='Refresh' Content='0; URL=brandmanagement.php?brand='$brand'&task='$task'>";    
    }

So the task and brand vars are getting from a form in the same page. But after doing the process I get this EMPTY url:

brandmanagement.php?brand=

So why is that, how to fix it?

Note that I don't want to use Header Location somehow!

Answer 1

Since you wish not to use the header function, then you should change this:

echo "<META HTTP-EQUIV='Refresh' Content='0; URL=brandmanagement.php?brand='$brand'&task='$task'>";    

Into this:

echo "<META HTTP-EQUIV='Refresh' Content='0; URL=brandmanagement.php?brand=". $brand ."&task=". $task ."'>";    

Or:

echo "<META HTTP-EQUIV='Refresh' Content='0; URL=brandmanagement.php?brand={$brand}&task={$task}'>";    

Or:

echo "<META HTTP-EQUIV='Refresh' Content='0; URL=brandmanagement.php?brand=$brand&task=$task'>";    

(although the last one is less readable and can lead to dangerous side effects as php tries to parse variable names)
