Updating database using dropdown without using a submit button - php

I'm trying to update the table status value whenever I make a selection from the dropdown list.
The problem is I'm having a syntax error on my update query. I've read stuff about syntax error and I can't quite understand it. I think I'm gonna need a more specific help. Here's what I've done:
<?php
$hostname = "localhost";
$username = "root";
$password = "";
$databasename = "companydb";
try
{
$conn = new PDO("mysql:host=$hostname;dbname=$databasename",$username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
if(isset($_POST["status"]))
{
$query = "UPDATE tickets SET status = '$status' WHERE id = $id";
$statement = $conn->prepare($query);
$statement->execute(array('status' => $_POST["status"]));
$count = $statement->rowCount();
if($count > 0)
{
echo "Data Inserted Successfully..!";
}
else
{
echo "Data Insertion Failed";
}
}
else
{
echo "unknown index: 'status'";
}
}
catch(PDOException $error)
{
echo $error->getMessage();
}
?>
And here's my table schema:

You are not performing prepared statements properly. You need to add the placeholder in the query and not the variables. The variables should be added in the execute() line.
$query = "UPDATE tickets SET `status` = :status WHERE `id` = :id";
$statement = $conn->prepare($query);
$statement->execute(array(':status' => $_POST["status"],':id' => $id));
Also FYI, $id is undefined.

Try Changing this:
$query = "UPDATE tickets SET status = $status WHERE id = $id";

I want to write code for check if data already exits then insert in different table

I already write the code to check if table call hm2_history type = commission if yes then insert data into table call hm2_deposit, when I test echo was correct and show the result is :
Connected successfully
354
368
But won't insert into hm2_deposit , I don't know how to adjust it i have a little bit knowledge about php
This is my code
<?php
$servername = "localhost";
$username = "tinybaht_findroom";
$password = "212224";
function setChecked($conn,$params){
$s = $conn->prepare("UPDATE `hm2_history`
SET history_ref_id=-1
WHERE id=:id
");
$s->execute($params);
}
try {
$conn = new PDO("mysql:host=$servername;dbname=tinybaht_findroom", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
$stmt = $conn->prepare("SELECT * FROM hm2_history");
$stmt->execute();
$stmt->setFetchMode(PDO::FETCH_ASSOC);
$a = $stmt->fetchAll();
$plans = array();
foreach($a as $i){
$plans[$i['type']] = 'commissions';
}

foreach($rows as $k=>$v) {
$plan_type = isset($plans)?:'';
$m = $v['type'];
if (!empty($plan_type)){
echo '<br>'.$v['id'];
if ($m = "commissions" ){
setChecked($conn,array('id'=>$v['id']));
continue;
}

this is photo of my db table name is hm2_deposits hm2_deposits
this is photo of my db table name is hm2_history enter image description here
There is an error in your SQL:
$s = $conn->prepare("INSERT INTO hm2_deposits
SET user_id=:user_id,

No Update done with PDO php

I have problem without any error in my code that update row ..

$count = $db->exec($sql);
//redirect to invoice page
header('Location: invoice.php');
exit;
//else catch the exception and show the error.
} catch(PDOException $e) {
$error[] = $e->getMessage();
}
}
This is my code , i try to get variable $sql and go to mysql phpmyadmin and its work good ,, but in file not work and i dont get any error
==== Update ====
i try this and not work
try {
$sql = 'UPDATE invoice SET client = :client, company = :company, clientemail = :clientemail, mobailclient = :mobailclient, startdate = :startdate, enddate = :enddate WHERE id = :id';
$statement = $db->prepare($sql);
$statement->bindParam(":client", $client);

Your query is opened for SQL Injection. You should use parameterized query which provide a kind of protection against SQL injection but will not provide 100% of protection. Kindly visit this Post for more details.
Try the following code by replacing table and column names.
$client = "my name";
$company = "my-company";
$id= 2;//make sure your table has a record with that specific id
$sql = 'UPDATE invoice SET client = :client, company = :company WHERE id = :id'; // here i am updating only two columns
//You can add more column that you want to upate like ColumnName = :ParameterIdentifier
//Where ParameterIdentifier Is the name of parameter used in bindParam as in my example company
$statement = $db->prepare($sql);
$statement->bindParam("client", $client); //Binding parameter for client
$statement->bindParam("company", $company); //Binding parameter for company
$statement->bindParam("id", $id);
$statement->execute();
if($statement->rowCount() > 0) // will return 1 if any row is updated
{
echo "Record updated successfully";
}
else
{
echo "No record updated";
}

changePSW function does not work

can you help out a beginner trying to learn PHP? I wrote a code for changing password without any validations yet, just to change it and it does not work. It's been days I've been trying and couldn't figure out what's wrong. Thanks in advance.
id is variable name in database where id is kept.
db connection is done with first line and it definitely works.
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
session_start();
print_r($_SESSION);
function changePSW()
{
//$password = $_POST['currPassword']; // required
$newPassword = $_POST['newPassword']; // required
//$newPassword2 = $_POST['NewPassword2']; // required
$newPasswordH = password_hash($newPassword, PASSWORD_DEFAULT);
echo($newPassword);
$id = $_SESSION['userID'];
echo($id);
// create PDO connection object
$dbConn = new DatabaseConnection();
$pdo = $dbConn->getConnection();
try {
$statement = $pdo->prepare("SELECT * FROM `users` WHERE id = :id LIMIT 1");
$statement->bindParam(':id', $id);
$statement->execute();
$result = $statement->fetchAll(PDO::FETCH_ASSOC);
echo "SADASDASD";
// no user matching the email
if (empty($result)) {
$_SESSION['error_message'] = 'Couldnt find user';
header('Location: /Online-store/userForm.php');
return;
}
$sql = "UPDATE users SET password=:newPasswordH WHERE id = :id";
// Prepare statement
$stmt = $pdo->prepare($sql);
echo "AFGHANIKO";
// execute the query
$update_status = $stmt->execute(array(':password' => $newPasswordH, ':id' => $id));
echo "IHAAA";
echo($update_status);
if ($update_status === TRUE) {
echo("Record updated successfully" . "\r\n");
echo nl2br("\nPassword: ");
echo ($newPassword);
echo nl2br("\nHashed Password: ");
echo ($newPasswordH);
return true;
} else {
echo "Error updating record";
die();
}
} catch (PDOException $e) {
// usually this error is logged in application log and we should return an error message that's meaninful to user
return $e->getMessage();
}
}
if($_SESSION['isLoggedIn'] == true) {
require_once("database/DatabaseConnection.php");
unset($_SESSION['success_message']);
unset($_SESSION['error_message']);
changePSW();
}
?>
$update_status = $stmt->execute(array(':newPasswordH' => $newPasswordH, ':id' => $id));
This is what I needed to have instead of
$update_status = $stmt->execute(array(':password' => $newPasswordH, ':id' => $id));

How to delete and update using php

Hello guys I have been trying to delete a file using php and I want it to delete the main post, reply's and like then update to the author -10 in his/her point.
Here is my code, using PDO:
<?php session_start();
if(isset($_POST['id'])){
include($root . 'dbconn.php');
$form = $_POST;
$id = $form['id'];
try {
$db_conn = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME,DB_USERNAME,DB_PASSWORD);
$db_conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $db_conn->prepare("DELETE FROM code WHERE cid= {$id}");
$stmt = $db_conn->prepare("DELETE FROM comment WHERE id = {$id}");
$stmt = $db_conn->prepare("DELETE FROM likes_map WHERE lid = {$id}");
$stmt = $db_conn->prepare("UPDATE users SET point -1 WHERE username = {$u}");
$stmt->bindParam(':id', $id);
$stmt->bindParam(':cid', $id);
$stmt->bindParam(':lid ', $id);
$stmt->bindParam(':u ', $_SESSION['username']);
$stmt->execute();
echo "deleted"
} catch(PDOException $e) {
echo "Error:" . $e->getMessage();
}
$db_conn = null;
}else{
echo "You are not allow to delete this";
}
?>
Your first problem is that you are preparing more than one query on the same statement handle and therefore loosing the link to that prepared statement when you prepare the next query.
You are also only executing the queries once and not once per statement!
Also your prepared sql statement do not have the parameters set with the correct syntax
It would also be a good idea to run this code inside a transaction, so if any update of the database fails you are not left with just bits of this process comepleted. This assumes the database is an INNODB database and not an MYISAM one, as transactions dont work on MYISAM
<?php
session_start();
if(!isset($_POST['id'])){
echo "You are not allow to delete this";
exit;
}
include($root . 'dbconn.php');
$form = $_POST;
$id = $form['id'];
try {
$db_conn = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME,DB_USERNAME,DB_PASSWORD);
$db_conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// start a transaction
$db_conn->beginTransaction();
$d_code = $db_conn->prepare("DELETE FROM code WHERE cid= :id");
$d_code->bindParam(':id', $id);
$d_comment = $db_conn->prepare("DELETE FROM comment WHERE id = :id");
$d_comment->bindParam(':id', $id);
$d_like = $db_conn->prepare("DELETE FROM likes_map WHERE lid = :id");
$d_like->bindParam(':id ', $id);
$u_user = $db_conn->prepare("UPDATE users SET point -1 WHERE username = :u");
$u_user->bindParam(':u ', $_SESSION['username']);
$d_code->execute();
$d_comment->execute();
$d_like->execute();
$u_user->execute();
$db_conn->commit();
echo "deleted";
} catch(PDOException $e) {
$db_conn->rollBack();
echo "Error:" . $e->getMessage();
}
$db_conn = null;
?>
