<input type="hidden" name="linkedin-id" value="<?js= id ?>" />
</script>
</body>
</html>


some common issues:


1)since we are using <?=js this may have effect in PHP short tags so i am making this project inside a directory and created .htaccess and switched off the short tag using the code in .htaccess file

2)Sometime while loading the page and you would not see the sign up botton at the page,so don't worry, just check your domain properly registered at app settings at linkedin developers app page.And if error occurs check out the console at the browser.

if you experience any errors just notify as comments.share is care.
