the error is giving me in the line of the WHILE cycle, I have tried to try different things but it keeps giving me this error

mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in

What I have tried:

<form method="post" action="book.php">
<input type ="hidde" name="send" value="ok">
<table border="0">
<td><input type="text" name="titel" size="20" maxlength="50"></td>
	<select name="auteur">
		$conection = mysql_query_connet("localhost","phpususer","php", "weblearning");
		$query ="SELECT auteursid, surnames, nome FROM auteur ORDER BY surnames";
		$results = mysql_query($conection, $query);
		while ( $row= mysqli_fetch_assoc($results)) {
			print("<option value=". $row["auteursid"]. ">" .$row["surnames"]. "".$row["nome"] ."</option");

	<td> number of page </td>
	<td><input type="text" name="page" size="20" maxlength="50"></td>
	<td><input type="submit" value="add"></td>

I wish I had £1 for every time this question gets posted. If you check the documentation for PHP: mysql_query - Manual[^] you will clearly see that when the query statement fails the call returns the boolean value FALSE. Do not assume that your API calls always do what you think; check the return values first.
