mysqli_query expects at least 2 parameters

Question

This mysqli_query command results in the error below

mysqli_query("INSERT INTO `counter`.`hits` (`page_hits`) VALUES (1)"); 
         


        

Answer 1

From the manual

Procedural style

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

You'll notice the $link and $query variables.

This means that you need to pass the function a valid mysqli link resource as well as the query you wish to perform. This lets the function know which established connection to the server to use.

A link resource can be created using:

Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

and an example of how to do so can be found on the aforementioned manual page.
