i do not know why the following code will not work for inserting data into mysql.
if (!$link = mysql_connect('server', 'user', 'password')) {
echo '700';
exit;
}
if (!mysql_select_db('vendors', $link)) {
echo '701';
exit;
}
$sql2 = "INSERT INTO transactions (TransID, payment_status, last_name, first_name, payer_email, address_name, address_state, address_zip, address_country, verify_sign, payment_gross, ipn_track_id, business, reciver_email) VALUES ('kris', 'kris', 'kris', 'kris', 'kris','kris', 'kris', 'kris', 'kris', 'kris', 'kris', 'kris', 'kris', 'kris')";
$result2 = mysql_query($sql2, $link);
What is wrong with the code?
php is giving no errors.
Please try not to use mysql_connect instead use mysqli_connect or PDO_MySQL read this
Also use die to find if there is any errors in your code
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
Otherwise(recommended way)-
Procedural style
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "INSERT INTO Persons (firstname, lastname, email)
VALUES ('Happy', 'John', 'john#example.com')";
if (mysqli_query($conn, $sql)) {
echo "New Person created successfully";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
MySQLi Object-oriented style
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO Persons (firstname, lastname, email)
VALUES ('Happy', 'John', 'john#example.com')";
if ($conn->query($sql) === TRUE) {
echo "New Person created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
Try changing this
$result2 = mysql_query($sql2, $link);
Into this
$result2 = mysql_query($sql2, $link)or die(mysql_error());
You have to write the code like below to get the errors in your code
$result = mysql_query($sql2,$link) or die(mysql_error());
this or die(mysql_error()) will give you errors in query

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!
function inseartinto()
{
$DEL_LOG_REP = $connection->prepare("DELETE FROM test WHERE itemname='111'")$DEL_LOG_REP->execute()$DEL_LOG_REP->close()return $DEL_LOG_REP
}
This is short tutorails on connection in insert query into php...
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john#example.com')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
For more better understand..go to http://www.w3schools.com/php/default.asp
What code are you trying to writing man..
This is not a valid code for just not insert but also for connetion..
ya go onto W3School.com as mention by #Sasa.D... it provide you with knowledge from basic to expertise..
I know this question has been answered many times. I tried a few of the solutions from here but nothing worked. I'm not using any PHP framework.
I have an insert operation taking place and I want to get the id of the inserted row.
Here's my code:
$qry="INSERT INTO tablename(content) VALUES('".$content."')";
setData($qry);
setData() is a user defined function which does insert operation.
//for data submit
function setData($qry)
{
$obj=new DBCon();
$res=$obj->submitQuery($qry);
return $res;
}
//fetches result
function getData($qry)
{
$obj=new DBCon();
$res=$obj->selectQuery($qry);
return $res;
}
This is the class I made for establishing database connectivity:
class DBCon
{
private function getConnection()
{
// hostname, username, password, database
$con=mysqli_connect("localhost","root","","dbname")OR die('Could not Connect the Database');
return $con;
}
public function closeCon()
{
mysqli_close($con);
}
public function submitQuery($qry)
{
$result=0;
$con=$this->getConnection();
$result=mysqli_query($con,$qry);
return $result;
}
public function selectQuery($qry)
{
$con=$this->getConnection();
$res=mysqli_query($con,$qry);
return $res;
}
}
To obtain the last inserted id, I wrote the following query but it did not yield any result:
SELECT LAST_INSERT_ID() FROM tablename
Is there any other method to get this?
LAST_INSERT_ID() only returns values that have been auto-generated by the MySQL server for an AUTO_INCREMENT column; when you insert a specific value, no auto-generation takes place and no value will be returned by LAST_INSERT_ID().
Try : $con->insert_id;
Try This way.
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('First Name', 'Last Name', 'first#example.com')";
if ($conn->query($sql) === TRUE) {
$last_id = $conn->insert_id;
echo "New record created successfully. Last inserted ID is: " . $last_id;
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}

I'm quite new to this php/mysql deal and I'm having a hard time figuring out this situation particularily.
I have two tables, one of them is "dog" table and the other one is the "date" table. In order to insert a record in the "dog" table I MUST first insert a date in the "table" date and get the autoincrement id from that date.
Problem is that I've tried reading several posts on how to get the last insert id from a table you just inserted a record on and I can't seem to make it work.
$sql1="INSERT INTO FECHAS (fecha) VALUES (NOW())";
mysql_query($sql1);
echo $sql1;
$sql3="SELECT LAST_INSERT_ID()";
mysql_query($sql3);
echo $sql3;
$sql2="INSERT INTO PERRO (nombre_perro,FECHAS_id_fecha) VALUES ('$nombre_perro_var', '$last_id')";
echo $sql2;
if (!$mysqli->query($sql2)) {
echo 'Error: ', $mysqli->error;
}
$result2 = mysql_query($sql2);
Please forgive this code, I'm new and learning.
Thanks!
Use mysqli instead of mysql_
Connecting with mysqli:
$connection = mysqli_connect($hostname, $username, $password, $database_name);
Inserting into a table:
mysqli_query($connection, $sql);
Retrieving last inserted id:
$id = mysqli_insert_id($connection);
**Database**
CREATE TABLE MyGuests (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)
**Example (MySQLi Object-oriented)**
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john#example.com')";
if ($conn->query($sql) === TRUE) {
***$last_id = $conn->insert_id;***
echo "New record created successfully. Last inserted ID is: " . $last_id;
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
**Example (MySQLi Procedural)**
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john#example.com')";
if (mysqli_query($conn, $sql)) {
***$last_id = mysqli_insert_id($conn);***
echo "New record created successfully. Last inserted ID is: " . $last_id;
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
?>
**Example (PDO)**
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDBPDO";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john#example.com')";
// use exec() because no results are returned
$conn->exec($sql);
***$last_id = $conn->lastInsertId();***
echo "New record created successfully. Last inserted ID is: " . $last_id;
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
A procedural solution (although it might be slightly wrong - I'm terrible at PHP)...
<?php
include('path/to/connection/stateme.nts');
$query = "
INSERT INTO fecha (fecha) VALUES (NOW());
";
mysqli_query($db,$query);
$query = "
INSERT INTO perro (nombre_perro,id_fecha) VALUES (?,?);
";
$nombre_perro = 'rover';
$id_fecha = mysqli_insert_id($db);
$stmt = mysqli_prepare($db,$query);
mysqli_stmt_bind_param($stmt, 'si', $nombre_perro,$id_fecha);
mysqli_stmt_execute($stmt);
?>
You might consider binding both queries into a transaction, so that in the event that the second query fails for some reason, then the first query fails too.
I'm not exactly sure what happened but this database and the php effecting it were working just fine until it hit the fourth row and now it won't insert new records at all.
if($_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.
