  2. Hi people I have a table created like this: -- -- Database: `mydatabase` -- -- -------------------------------------------------------- -- -- Tablestructure for table `table_name` -- CREATE TABLE `table_name` ( `num` int(4) NOT NULL, `fol_num` int(7) DEFAULT NULL, `col3` varchar(30) DEFAULT NULL, `col4` int(1) DEFAULT NULL, `num_nonce` varchar(20) DEFAULT NULL, `col6` varchar(30) DEFAULT NULL, `col7` varchar(15) DEFAULT NULL, `col8` varchar(15) DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1; -- I also created a function and the goal of the function is to read the random number from fol_num with a mysql query with WHERE. fol_num should match with the number found and show num_nonce belonging to that record. query: SELECT num_nonce, FROM table_name WHERE fol_num = ? ; function: <?php function my_func() { // global global $fol_num; global $num_nonce; $servername = "localhost"; $username = "myname"; $password = "mypassword"; $dbname = "mydatabase"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } var_dump($fol_num); // select nonce from database table $stmt = $conn->prepare("SELECT num_nonce, FROM table_name WHERE fol_num = ? ;" ) ; $stmt->bind_param('is', $fol_num, $num_nonce); $stmt->execute(); $stmt->bind_result($fol_num, $num_nonce); $stmt->fetch(); var_dump($num_nonce); // var_dump($fol_num2); //$stmt->close(); $conn->close(); } my_func(); ?> I receive errors that sound like: Fatal error: Uncaught Error: Call to a member function bind_param() on boolean in ...... pointing to this line: $stmt->bind_param('is', $fol_num, $num_nonce); what is not good and how to solve it?
  3. I have the following peace of code. I cant solve how to fetch all the records in the database. I have to use prepare but if I use place holders for $sql then it doesnt work I tried foreach and while but I dont know how to use it. Can someone please tell what code to use to fetch multiple records from a table? <?php // make connection to database $sql = "SELECT id_nr, name FROM table;"; $id_nr =1; if ($stmt = $conn->prepare($sql)) { $stmt->bind_param('i', $id_nr); $stmt->execute(); $stmt->store_result(); $num_of_rows = $stmt->num_rows; $stmt->bind_result($id_nr, $name); while ($stmt->fetch()) { echo ' id number : ' . $id_nr . '<br>'; echo ' name : ' . $name . '<br>'; } $stmt->free_result(); } $stmt->close(); mysqli_close($conn); } ?>
