PHP - Error In Mysqli
hi guys
i get an error in this code (comment in the code): I Code: [Select] if (checkBd ($sql, $db, $valor, $codePass)){ ($sql = $db->prepare("UPDATE users SET activation = ? WHERE activationLink=?")); $valor="1"; $sql->bind_param('is', $valor, $codePass); $sql->execute(); $sql->bind_result($valor, $codePass); //Warning: mysqli_stmt::bind_result() [mysqli-stmt.bind-result]: Number of bind variables doesn't match number of fields in prepared statement if ($sql->fetch()) { header("location: index.php"); return true; } else { echo "no"; return false; } $sql->close(); $db->close(); } what is the possible problem in the script? an another question, is this way correct to update a boolean? thanks Similar TutorialsI closed everything down last night and it was all fine, website was working as normal etc, but I've turned on the Xxamp server today and I am getting this error. Seems very random as nothing has changed since it was last on? Does anyone know how to sort this out and why I'm now getting this error? Thanks! hello i tried to switch from mysqli to pdo but somehow i made a mistake

Hi, 3 different tutorials teach 3 different ways on how to get php mysqli echo connection errors.
Which one should I memorise out of these 3 you advise ?
1.
$link = mysqli_connect("127.0.0.1", "my_user", "my_password", "my_db");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
mysqli_close($link);
2.
$link = mysqli_connect("localhost", "root", "");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Print host information
echo "Connect Successfully. Host info: " . mysqli_get_host_info($link);
// Close connection
mysqli_close($link);
3.
mysqli_connect("localhost", "root", "", "GFG");
if(mysqli_connect_error())
echo "Connection Error.";
else
echo "Database Connection Successfully.";
Q2. On the connection point check, you give your rankings on these following 3 based on your preference.
A. if(mysqli_connect_error())
B.
if($link === false){
C.
if (!$link) {
A.
die("ERROR: Could not connect. " . mysqli_connect_error());
B. echo "Connection Error.";
C. echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL; echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
Briefly, let me know: A). Which connection error checking point to use and which error message echoing point to use. B). If you got your own that is better and more helpful then explain why it is better over these 3 and any others. Hi, I have taken the step of writing my site in MySQLi instead of MYSQL as advised. However, I had a script that I got off the internet, the original file works great and registers the user to the database. However the edited version of the script, where I have added more information such as the users address etc, no longer works. I have compared the two files and can't seem to find the problem. When the script is run, it skips all the registration part and jumps to the last error in the script saying 'You Could Not Be Registered Because Of Missing Data.'. All the variables match the column names in the database.
Here is the original working script
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
// some error checking

if($_POST['reg']){

}else{ echo "form not submitted"; }

Hey all, I'm having some trouble running some mysql statements through mysqli. I've tried to debug them various ways, but to no avail. This is the offending code: class DBOPS { protected $config, $mysqli; public function __construct () { $this->config = array (...snip...); $this->mysqli = new mysqli ($this->config['server'], $this->config['username'], $this->config['password'], $this->config['database']); session_start(); } public function Login ($username, $password) { $toreturn = NULL; //Problem area is from here... $encryptedpassword = hash(...snip...); print_r(array( $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword)); $statement = $this->mysqli->stmt_init(); $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?'); $statement->bind_param( 'ssss', $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword); $statement->execute(); print_r($statement->affected_rows); //To here. if ($statement->affected_rows == 1) { $_SESSION[$this->config['sessiondata']['username']] = $username; $_SESSION[$this->config['sessiondata']['lastactivity']] = time(); $toreturn = TRUE; } else { $toreturn = FALSE; } $statement->close(); return $toreturn; } The print_r($statement->affected_rows); statement always returns -1, which means a query error. Is there a problem with the syntax of the predefined query in $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?') ? I really can't seem to find the problem in this code. There are no errors returned. The output from the print_r() statements are Code: [Select] Array ( [0] => Name [1] => Trey [2] => Password [3] => ...snip... )from the first print_r and Code: [Select] -1from the second. And lastly, I know that DIY login systems are generally discouraged, but this is more of a research project. I would greatly appreciate any help with this. Thanks.

I have an error in the update, but I am not seeing where I made it. Its annoying because the update won't execute and anything beyond the update isn't visible in the html source code in the browser, so it is likely to be a syntax error, but where?

Sets up a mysqli connection script which I retrieve with included. If a user enters the wrong password or username then the connection to the database will be interrupted, and a message will be given about this. I want to do this in a different way. I want the .php connection script to work so that the script lets me or the ser know if it is the password that is incorrect or the username that is not authenticated. This way the user can find out if he / she has entered the wrong password or username. If both are incorrect, notice of this will be given. connection file is a fairly standard script. I have no clue about how to solve this problem. Is it posible at all? Do you know how to do it?
<? MySQL returns an error in the form of a number, a state, and a message. Without parsing the message you will not be able to determine what column is duplicated.While parsing the error code, I have also notice that, if you have multiple unique fields as duplicates, only the first duplicate encountered will be returned in the message. This is not very helpful to the end user.
Is there any way to parse the returned error code to reflect all duplicate fields, please see sample code below?
$error=array();
$sql = 'INSERT INTO staff(username, email, phone)
VALUES (?, ?, ?)';
$stmt = $conn->stmt_init();
$stmt = $conn->prepare($sql);
// bind parameters and insert the details into the database
$stmt->bind_param('sss', $username, $email, $phone);
$stmt->execute();
if ($stmt->errno == 1062) {
$errors[] = "One of the fields is already in use.";

Hello all, I'm an amateur at PHP coding, and am currently enrolled in a PHP and MySQL class that uses the PHP Programming with MySQL textbook, by Don Gosselin. I'm trying to get this simple Shopping Cart script to work, because it's the step-by-step example script for Chapter 11, but I keep getting the following errors on ShowCart.php when I try to add an item to the cart.

I have just started using MySQLi and am clueless it is giving me the follow errors in which i do not understand
Warning: mysqli_select_db() expects exactly 2 parameters, 1 given in C:\xampp\htdocs\Login\connect.php on line 23 Notice: Trying to get property of non-object in C:\xampp\htdocs\Login\connect.php on line 25 Notice: Use of undefined constant mysqli - assumed 'mysqli' in C:\xampp\htdocs\Login\connect.php on line 32 Warning: mysqli_query() expects parameter 1 to be mysqli, string given in C:\xampp\htdocs\Login\connect.php on line 32 Warning: mysql_fetch_assoc() expects parameter 1 to be resource, null given in C:\xampp\htdocs\Login\connect.php on line 33 can someone please explain to me why i am getting these? and my code is
$mysqli_db = mysqli_select_db("$db_name");
if($mysqli_db->connect_errno) {
printf("Database not found: %s\n", $mysql->connect_error);
exit();
}
$sql = "SELECT * FROM $tbl_name WHERE username='$username' AND password='$password'";
$result = mysqli_query($sql);
$row = mysqli_fetch_assoc($result);
I just got rid off most the errors the only ones left are

exit();
}
$sql = "SELECT * FROM $tbl_name WHERE username='$username' AND password='$password'";
$query = mysqli_query($sql);
$result = mysqli_result($query);
$row = mysqli_fetch_assoc($result);
Edited by Tom8001, 30 November 2014 - 12:43 PM. When running the following code i get the error: Call to undefined method mysqli::errno() the code: $conn = new mysqli(HOST, USER, PASSWORD, DATABASE); if ($conn->errno() !== 0) { $msg = $conn->error(); throw new connErrorException($msg, 'Connect'); } I am fairly new to classes but as i understand it this should be correct. I am using mysql 5.1 so mysqli is on by default. I have even checked the php ini and everything looks fine there in respect to this. Any advice? I am using mysqli, OO, to connect to MySQL. I have only today started looking at this and am used to: Code: [Select] <?php $con = mysql_connect();//etc mysql_close($connection); ?> Am I right that with mysqli (OO) that I don't need to set a connection variable wither when connecting or closing?? Code: [Select] <?php mysqli::connect();//etc mysqli::close(); ?> What about with multiple databases, does mysqli keep track for me, as I am used to this: Code: [Select] <?php $con1 = mysql_connect();//db1 $con2 = mysql_connect();//db2 ?> //etc Hi, The following code is what I want in that it creates a menu and I can select and display a table row.
I still need to use that selection to update the "lastused". I really appreciate your help. <!DOCTYPE><html><head><title>email menu</title></head> <body><center> <form name="form" method="post" action=""> <?php $con=mysqli_connect("localhost","root","cookie","homedb"); //============== check connection if(mysqli_errno($con)) {echo "Can't Connect to mySQL:".mysqli_connect_error();} else {echo "Connected to mySQL</br>";} //This creates the drop down box echo "<select name= 'target'>"; echo '<option value="">'.'--- Select email account ---'.'</option>'; $query = mysqli_query($con,"SELECT target FROM emailtbl"); $query_display = mysqli_query($con,"SELECT * FROM emailtbl"); while($row=mysqli_fetch_array($query)) {echo "<option value='". $row['target']."'>".$row['target'] .'</option>';} echo '</select>'; ?> <input type="submit" name="submit" value="Submit"/><!-- update "lastused" using selected "target"--> </form></body></html> <!DOCTYPE><html><head><title>email menu</title></head> <body><center> <?php $con=mysqli_connect("localhost","root","cookie","homedb"); if(mysqli_errno($con)) {echo "Can't Connect to mySQL:".mysqli_connect_error();} if(isset($_POST['target'])) { $name = $_POST['target']; $fetch="SELECT target,username,password,emailused,lastused, purpose, saved FROM emailtbl WHERE target = '".$name."'"; $result = mysqli_query($con,$fetch); if(!$result) {echo "Error:".(mysqli_error($con));} $lastused = "CURDATE()"; // update "lastused" using selected "target" //display the table echo '<table border="1">'.'<tr>'.'<td bgcolor="#ccffff align="center">'.

Can someone give me a solution and tell me what I've done wrong?

I dont know whether the statement is correct.....i just tried it.....and it didn't work. $stmt->bind_param('ssiiiss',$_POST['name'],$_POST['email'],$_POST['d'],$_POST['m'],$_POST['y'],$_POST['add'],$_POST['phone']); here my first two values are strings and next 2 tiny int's next is int and last 2 again strings. Ok I am trying to use mysqli instead of the usual mysql. Mysql would be outdated. With mysqli, sgl-injection is impossible if you use the "?" in those codes. I would normally use a function but I've made a simple script to find the error. I use $parameters and $sql because these are the data I need to give as parameters to the function, so I used it here too but without the function actually. Code: [Select] ini_set('display_errors',1); // 1 == aan , 0 == uit error_reporting(E_ALL | E_STRICT); # sql debug define('DEBUG_MODE',true); // true == aan, false == uit $userid = 11; $lang = 1; $newLink = "testing123"; $db_host = "localhost"; $db_gebruiker = "root"; $db_wachtwoord = ''; $db_naam = "projecteasywebsite"; $sql= "INSERT tbl_link(userid,linkcat,linksubid,linklang,linkactive,linktitle) VALUES(?, ?, ?, ?, ?, ?)"; $parameters = '"iiisis", $userid, 1, 0, $lang, 1, $newLink'; echo $parameters; $mysqli = new mysqli($db_host, $db_gebruiker, $db_wachtwoord, $db_naam); $stmt = $mysqli->prepare($sql); $stmt->bind_param($parameters); $stmt->execute(); echo "<br><br>". mysqli_connect_errno(); echo "<br><br>". mysqli_report(MYSQLI_REPORT_ERROR); $stmt->close(); $mysqli->close(); I got Wrong parameter count for mysqli_stmt::bind_param() So naturally a problem when we execute : Warning: mysqli_stmt::execute() [mysqli-stmt.execute]: (HY000/2031): No data supplied for parameters in prepared statement ($stmt->execute() Is someone using mysqli too ? The following code is supposed to submit everything in the database on a table, Currently its doing the first row in the database. Not sure whats wrong.. function getNews(){ $query = $this->con->query("SELECT * FROM `". $this->prefix ."news`"); while ($result = $query->fetch_assoc()) { if($result['serveradded'] == 1){ $queryy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE serveradded=1"); while ($resultt = $queryy->fetch_assoc()) { return "<tr><td>The Advertisement ". ucfirst($resultt['name']) ." was created</td><td>". $resultt['date'] ."</td></tr>"; } } elseif($result['servupdate'] == 1){ $queryyy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE servupdate=1"); while ($resulttt = $queryyy->fetch_assoc()) { return "<tr><td>". $result['type'] ." ". ucfirst($resulttt['name']) ." was Updated by ". ucfirst($resulttt['updatedby']) ." </td><td>". $resulttt['date'] ." </td></tr>"; } } elseif($result['newuser'] == 1){ $queryyyy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE newuser=1"); while ($resultttt = $queryyyy->fetch_assoc()) { return "<tr><td>Account Created: ". ucfirst($resultttt['name']) ." was created</td><td>". $resultttt['date'] ."</td></tr>"; } } } } |
