You don't need to select the same column twice.

The %s in the print_f format argument are placeholders for the string variables ($row['type_chocolate'])

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = mysqli_connect("localhost", "root", "P-11fl32fg14", "cocoa");

$query = "SELECT type_chocolate FROM type_chocolate";

$result = mysqli_query($mysqli, $query);

while ($row = mysqli_fetch_assoc($result))

{
    printf("<a href='cacau_type_chocolate.php?type_chocolate=%s'>%s</a>", $row['type_chocolate'], $row['type_chocolate']);
}
