Whenever I submit my php form, the data shows up blank in the database. What is not working? I've tried to setup the code different, but no matter what I do, the values ends up being blank.
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
if (isset($_POST["email"]))
{
$login = $_POST["email"];
}
else
{
$login = null;
}
if (isset($_POST["psw"]))
{
$psw = $_POST["psw"];
}
else
{
$psw = null;
}
$login2 = mysqli_real_escape_string($conn, $login);
$psw2 = mysqli_real_escape_string($conn, $psw);
$verify = "INSERT INTO test (email, password) VALUES ('$login2', '$psw2')";
$verify2 = mysqli_query($conn, $verify);
$conn->close();
?>
Try this:
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
if(isset($_POST['login']) and isset($_POST['email'])){
$insert = mysqli_query("INSERT INTO test VALUES('".$_POST['login']."', '".$_POST['email']."')");
if($insert){
echo "Dados inseridos.";
}
}
$conn->close();

I am trying to connect my php code to my database and once I input and submit things like username, email address, and password in my html form. They will be sent to my database and shown in specific columns and there will be text like "New record has been created successfully" on my page. But for now, an error occurs instead.
The following is my php code
<?php
$visitorname = $emailaddress = $visitorpassword = $confirmpassword = "";
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "mydb";
if($_SERVER["REQUEST_METHOD"] == "POST"){
$visitorname = input($_POST["visitorname"]);
$emailaddress = input($_POST["emailaddress"]);
$visitorpassword = input($_POST["visitorpassword"]);
$confirmpassword = input($_POST["confirmpassword"]);
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
}
function input($data){
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
if($visitorpassword == $confirmpassword){
// Create connection
$conn = new mysqli($servername, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
$id = mysqli_insert_id($conn);
$sql = "INSERT INTO registereduser (id, username, emailaddress,
hashedpassword) VALUES ($id, $visitorname, $emailaddress,
$hashed_password)";
if ($conn->query($sql) === TRUE){
echo "New record created successfully";
}else{
echo "Errors " . $sql . "<br>" . $conn->error;
}
$conn->close();
}else{
echo "Passwords do not match";
}
?>
The following is the error output shown on my web page:
Connected successfullyErrors INSERT INTO registereduser (id, username, emailaddress, hashedpassword) VALUES (0, Josh5577, josh1998#hotmail.com, $2y$10$RMasEdVOskmcXbmfchLeBeUzLa5l38jXFaCQN7vMEhR8A0mU/iiC6)
No database selected
Please use below code for connection
$conn = new mysqli($servername, $username, $password, $dbname);
You can try to change
// Create connection
$conn = new mysqli($servername, $dbname);
to
// Create connection
$conn = new mysqli($servername, $username, $password);
mysqli_select_db($conn, $dbname);
I've been trying to figure out how to insert data into mySQL database for a long time. When I try to insert data, it returns "no database selected". I'm not too sure what's wrong with the code, could someone check it out?
<?php
$servername = "localhost";
$database= "learnsc2_ts";
$username = "learnsc2_admin";
$password = "Ts#123";
$conn = new mysqli($servername, $username, $password, $database);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
else {
echo "Connection successful";
}
$query = "INSERT INTO users(fname, lname) VALUES ('Owen',
'Feng')";
mysqli_query($conn, $query);
if (mysqli_query($conn, $query)) {
echo "New record created successfully";
} else {
echo "Error: " . $query . "<br>" . mysqli_error($conn);?>
Make sure your database name is correct.
i tested it in my local, It's work Just fine.
$servername = "localhost";
$database= "test";
$username = "root";
$password = "";
$conn = new mysqli($servername, $username, $password, $database);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$query = "INSERT INTO users(fname, lname) VALUES ('Owen',
'Feng')";
$query = mysqli_query($conn, $query);
if ($query) {
echo "New record created successfully";
} else {
echo "Error: " . $query . "<br>" . mysqli_error($conn);
}
You forgot to add database name
$conn = new mysqli($servername, $username, $password, $database);
I figured it out. Something was wrong with the old username I was using. After changing to a new username and database, it worked out!
My table has 2 fields a primary with auto increment and then entry_id
why does the below not insert in the table:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
$conn->close();
?>
but when adding a error check it does?
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
if ($conn->query($sql) === TRUE) {
echo "";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
cant get my head around why this would be happening.
I'm not exactly sure what happened but this database and the php effecting it were working just fine until it hit the fourth row and now it won't insert new records at all.
if($_POST)
{
$servername = ******;
$username = ******;
$password = ******;
$db = ******;
$conn = mysqli_connect($servername, $username, $password, $db);
mysqli_select_db($conn,$db);
$uuid = $_POST['uuid'];
$sql = "INSERT INTO uuid VALUES ('$uuid');";
mysqli_query($conn,$sql);
mysqli_close($conn);
}
I'm not sure what happened but this is the relevant code for the mysqli query.
try this
<?php
if(isset($_POST['uuid']))
{
$servername = yourServerName;
$username = username;
$password = password;
$dbname = databaseName;
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$uuid = $_POST['uuid'];
$sql = "INSERT INTO tableName (columnName) VALUES ('$uuid')";
if (mysqli_query($conn, $sql)) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
}
?>
Also, I recommend using prepared statements.
I am doing an update of values inside a MySQL database using PHP
and here is my code to update
$id = $_REQUEST['uid'];
$name = $_REQUEST['name'];
$company = $_REQUEST['company'];
$contact = $_REQUEST['contact'];
$email = $_REQUEST['email'];
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
echo "$id "."$name". "$company" . "$contact" . "$email";
if ($conn->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
else
{
$sql = "UPDATE `users` SET `userName`='$name',`userEmail`='$email',`userCompany`='$company',`userContact`='$contact' WHERE userID = $id";
if (mysqli_query($conn, $sql))
{
mysqli_commit($conn);
echo "success";
}
else
{
echo "error";
}
}
mysqli_close($conn);
it does the update and changes the value in the db.
But when I login using the previous username and password, it still accepts it
code for login
$uname= $_REQUEST['loginusername'];
$pword= $_REQUEST['loginpassword'];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
else
{
$sql = "SELECT * FROM `users` WHERE userName = '$uname' AND userPassword = '$pword'";
$return = mysqli_query($conn, $sql);
if(mysqli_num_rows($return) > 0)
{
echo 'found';
}
else
{
echo 'not found';
}
}
$conn->close();
thanks in advance
You don't update your Password field in
UPDATE `users` SET `userName`='$name',`userEmail`='$email',`userCompany`='$company',`userContact`='$contact' WHERE userID = $id
and it isn't a good practice to save clear text passwords. Its better to hash it with an hash algorithm (for example sha256) and salt it.
