     You need to specify the connection that you made to your database somewhere earlier in your page. You should put that variable in the query. Suppose you made a variable called $con. Then your code should be like this.

     mysqli_query($con,"INSERT INTO `counter`.`hits` (`page_hits`) VALUES (1)"); -

     There are a few things wrong here.

     Firstly, you need to pass db connection to your query.

     What you are presently using:

     $result = mysqli_query($sql);-

     What you need to use instead:

     $result = mysqli_query($link, $sql);-

     Read the documention:

     Procedural style

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

     Then, you have a trailing comma in your query after cat_description

     $sql = "SELECT cat_id, cat_name, cat_description, <<< right there FROM categories";

     Checking for errors on your query would have spotted that.

     Bonus answer to code you didn't post originally but left in a comment instead:

     To answer what you posted above and not being part of your original question, is that your echo wrapping quotes are single quotes and you are also using single quotes inside there.

     You're using single quotes for both the opening and closing statement and using single quotes for what is inside the echo statement.

     Rewrite:

     echo "<p><form method='post' action='create_cat.php'></p> Category name: <input type='text' name='cat_name' /> Category description: <textarea name='cat_description' /></textarea> <input type='submit' value='Add category' /> </form>";

     The documentation of mysqli_query()

     clearly states the two alternatives how use that method. You mix both, which won't work.

     Ignoring quite a number of other issues I dare say this modification of your class will bring you closer to what you are looking for. It stores the database connection object inside a class property so that it can be reused for the actual queries.

     <?phprequire_once("dbconn.php");class dbcrud { private $dbconn; public function __construct(){ $this->dbconn = new dbconn; } public function create($Supplier_ID, $Company_Name){ $result = mysqli_query( $this->dbconn, "INSERT INTO suppliers(Supplier_ID, Company_Name) VALUES('$Supplier_ID','$Company_Name')" ); return $result; } public function read(){ $result = mysqli_query( $this->dbconn, "SELECT * FROM suppliers" ); return $result; } public function update($Supplier_ID, $Company_Name){ $result = mysqli_query( $this->dbconn, "UPDATE suppliers SET Company_name='{$Company_Name}' WHERE Supplier_ID={$Supplier_ID}'" ); return $result; } public function delete($Supplier_ID){ $result = mysqli_query( $this->dbconn, "DELETE FROM suppliers WHERE Supplier_ID={$Supplier_ID}" ); return $result; }}

     However this is only part of a solution. You really need to work through some tutorials to learn how to code database stuff. For one there are huge security implications in your code. You need to learn about the benefits of using "prepared statements" in combination with "parameter binding" to prevent sql injection vulnerability.

     So take this as a starting point, lot's of other issues remain unanswered...
