What does the mysqli_error() expects parameter 1 to be mysqli, null given mean?

Question

I have this PHP page:

Answer 1

Hi please don't confuse with mysql_connect(); with mysqli_connect();

Try to change as follows

$conn=mysqli_connect("yourhost", "username", "password", "database-name") or die("initial host/db connection problem");`

Then if its connected then pass your query with

mysqli_query($conn, "your query string") or die ("query not executed");`

Now it works fine! (mods, removed a to quer.r.y)
