How to use php code in javascript alert in codeigniter

Question

I am using this code in my controller and it's not working, showing parse error. Can you guys please help me out.

 echo "<script>
        alert("<?php echo $v[$keys[$i+4]],"is going out of stock"; ?>");
</script>" ;

Thank you!

include your error message.$v[$keys[$i+4]],"is going out of stock" should be $v[$keys[$i+4]]."is going out of stock" dot not comma — Shaiful Islam

don't use alert it locks the browser, use a modal overlay or other form of notification like a growl — cmorrissey

Try to avoid spaghetti code, separe in different layers javascript from controller, you should at least put it inside some view, never in the controller, it brokes the mvc pattern — Manjar

You're not concatenating the static text correctly. Try this:

echo "<script>
    alert('" . $v[$keys[$i+4]] . " is going out of stock.');
</script>" ;
