I'm trying to call jsfunction() from php. This jsfunction() will redirect me to code.php. But, it's not working and not showing any error.

<?php
    $sid=$_GET['link'];
    echo '<script type="text/javascript">';
    echo  'jsfunction();';
    echo   '</script>';

?>

<script type="text/javascript"></script>
<script>
    function jsfunction()
    {
        var site_id="<?php echo $sid; ?>";
        window.location.href = "code.php?site_id=" + site_id; 
    }
</script>

  • you cant call js from php. php runs on a server somewhere, and js in the client application (browser or other). – YvesLeBorg Jun 30 '17 at 11:56
  • Instead you can write that javascript function code in php itself. – Rahul Jun 30 '17 at 11:57

As @Deljoei suggested you can redirect user using header. Coming to your question why this isn't working is because jsfunction(); which you are calling before which result in error, because jsFunction is not defined. If you will change your code to

<?php
$sid=$_GET['link'];
?>

<script type="text/javascript"></script>
<script>
    function jsfunction()
    {
        var site_id="<?php echo $sid; ?>";
        window.location.href = "code.php?site_id=" + site_id; 
    }
</script>
<?php
    echo '<script type="text/javascript">';
    echo  'jsfunction();';
    echo   '</script>';
?>

then you will achieve what you want do. Now you when jsFunction is called, it will not give error because it is defined earlier.

You need to use php header for redirecting instead. Use the following code to redirect the user to the specific url : 

header('location:code.php?site_id='.$sid);
exit();

You need to declare function before use, try this:

<?php
    $sid=12;

?>

<script type="text/javascript"></script>
<script>
    function jsfunction()
    {
        var site_id="<?php echo $sid; ?>";
        window.location.href = "code.php?site_id=" + site_id; 
    }
</script>

<script type="text/javascript">;
jsfunction();
</script>;

Do like this:

$sid=$_GET['link'];
if($sid){
header('location:code.php?site_id='.$sid);
exit();
}

I hope this helps!

Try this

<?php
    $sid=$_GET['link'];
    echo '<script type="text/javascript">';
    echo  'jsfunction('.$sid.');';
    echo   '</script>';

?>

<script type="text/javascript"></script>
<script>
    function jsfunction(id)
    {
        var site_id=id;
        window.location = "code.php?site_id=" + site_id; 
    }
</script>
