PHP - Call To A Member Function Bind_param()
I get this error when I run my login system.
Call to a member function bind_param() on a non-object in /models/class.newuser.php on line 131This is the modified code (Line 131 is on the top line):
$stmt->bind_param("ssssi", $this->username, $secure_pass, $this->clean_email, $this->activation_token, $this->user_active);
$stmt->execute();

It fails on the BIND_PARAM line.
I have looked at this all day, struggling with Mysqli as my normal MySql works fine with assoc and fetch.
I have verified in PhpInfo that mysqli is enabled. I have verified its loaded using <?php print_r(get_loaded_extensions()); Added utf8 just to make sure.
If I manually use the Wrong Password, I get a connection refused error, so I know its connected.
Verified my $_POST variables are there using Print in the 2 9 0 1 above.
All Table and Field Names are correct. Manual Insert works fine in myPhpAdmin. Tried Field Names and ? marks with and without single quotes. All fields are Integers in the table.
Could it be related to an Auto_Increment Field in the table for a record ID that I am not providing?? A normal insert in myPhpAdmin doesn't need it.
$QuestionID = $_POST['qID']; print $QuestionID . " ";
Thanks, CadJoe Edited August 26, 2017 by CadJoeI'm new to coding and prepared statements.
I'm getting: For this:
<?php
include "db_connect.php";
if(isset($_POST['UserID'])){
$stmt = $con -> prepare('UPDATE UserList
SET Status = ?,
FirstName = ?,
LastName = ?,
Username = ?,
Email = ?,
Department = ?,
Manager = ?,
WHERE UserID = ?');
$stmt -> bind_param('isssssss', /* Line 17 */
$_POST['Status'],
$_POST['FirstName'],
$_POST['LastName'],
$_POST['Username'],
$_POST['Email'],
$_POST['Department'],
$_POST['Manager'],
$_POST['UserID']);
$stmt->execute();
}
Thank you in advance for helping. This topic has been moved to Other Libraries and Frameworks. http://www.phpfreaks.com/forums/index.php?topic=319682.0 I can call the following function successfully as a single php program // Acknowledge and clear the orders function ack($client, $merchant, $id) { $docs = array('string' => $id); $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs); $result = $client->call('postDocumentDownloadAck', $params); return $result; } with $result = ack($t, $merchant,'2779540483'); successful output [documentDownloadAckProcessingStatus] => _SUCCESSFUL_ [documentID] => 2779540483 I'm trying to figure out how to call this function as an object from another program.

NOTE: I also require dbcon.php at the top of the confirmation.php file which is NOT included in the excerpt at the top. Making pdo a global variable would probably fix it, but from what I heard globals are frowned upon. I am just trying out PDO and I get this error, Fatal error: Call to a member function fetch() on a non-object, but isn't it already on the $this->db object? class shoutbox { private $db; function __construct($dbname, $username, $password, $host = "localhost" ) { # db conections try { $this->db = new PDO("mysql:host=".$hostname.";dbname=".$dbname, $username, $password); } catch(PDOException $e) { echo $e->getMessage(); } } function getShouts() { $sql_shouts = $this->db->query('SELECT shoutid, message, pmuserid, ipadress, time FROM shouts WHERE pmuserid == 0'); return $sql_shouts->fetch(PDO::FETCH_OBJ); } } I am changing my script from connecting to the database within every function, to using one connection (in the main class).

Hi guys, I am trying to implement a Pagination class for a website displaying movies. I need to have the total number of posts, but on accessing the function row_count() from class Connection I get the error: "Fatal error: Uncaught Error: Call to a member function query() on null in ..\connection.php:30 Stack trace: #0 from ...\index.php(20): Connection->row_count() #1 ..." I only found two posts concerning this issue, and they led me to think this might be a scope issue with $db variable; $db is defined in the constructor function of the same Connection class so I thought the scope would be ok; but apparently, not. Can anybody help? This is a real show-stopper just now. Please let me know if you need any further information. Thanks in advance. Sept connection.txt index.txt |
