Question

Here is the code I have,

<script language="JavaScript">
    var url = "http://localhost:8888/uploads/"+<? $name ?>+"/output.txt";
    setTimeout("top.location.href = url",1000);
</script>

$name is a PHP variable which has the name of which directory I’m trying to redirect to.

Needless to say, it isn’t working. What’s wrong with it? I don’t know a lot about javascript so I probably did something stupid

Thanks

If your mixing PHP with JavaScript, it’s always advisable to check the output being sent to the browser: right click on your website and click view source!

JavaScript doesn’t care whether the content being sent to it is static HTML, from a Database or generated by PHP. If its in the output, it’ll parse it.

If you’d have done that, you’d notice that your not echo‘ing the $name variable.

<script language="JavaScript">
    var url = "http://localhost:8888/uploads/"+<? echo $name ?>+"/output.txt";
    setTimeout("top.location.href = url",1000);
</script>

But that’d give you

<script language="JavaScript">
    var url = "http://localhost:8888/uploads/"+ foo +"/output.txt";
    setTimeout("top.location.href = url",1000);
</script>

Which isn’t valid JavaScript, as foo is now a JS variable, not a string.

So you should have:

<script language="JavaScript">
    var url = "http://localhost:8888/uploads/<? echo $name ?>/output.txt";
    setTimeout("top.location.href = url",1000);
</script>

Furthermore, passing a string to setTimeout (or setInterval) is not recommend; for the same reasons against using eval(), so you should end up with something like this instead:

<script language="JavaScript">
    var url = "http://localhost:8888/uploads/<? echo $name ?>/output.txt";
    setTimeout(function () {
        top.location.href = url
    },1000);
</script>
