PHP MySQL Insert Record

After a database and a table have been created, we can start adding data in them.

Here are some syntax rules to follow:

  • The SQL query must be quoted in PHP
  • String values inside the SQL query must be quoted
  • Numeric values must not be quoted
  • The word NULL must not be quoted

The INSERT INTO statement is used to add new records to a MySQL table:

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)

In the previous chapter we created an empty table named "MyGuests" with five columns: "id", "firstname", "lastname", "email" and "reg_date". Now, let us fill the table with data.

Note: If a column is AUTO_INCREMENT (like the "id" column) or TIMESTAMP (like the "reg_date" column), it is no need to be specified in the SQL query; MySQL will automatically add the value.

Example

  1. <?php  
  2. $host = 'localhost:3306';  
  3. $user = '';  
  4. $pass = '';  
  5. $dbname = 'test';  
  6.   
  7. $conn = mysqli_connect($host, $user, $pass,$dbname);  
  8. if(!$conn){  
  9.   die('Could not connect: '.mysqli_connect_error());  
  10. }  
  11. echo 'Connected successfully<br/>';  
  12.   
  13. $sql = 'INSERT INTO emp4(name,salary) VALUES ("sonoo", 9000)';  
  14. if(mysqli_query($conn, $sql)){  
  15.  echo "Record inserted successfully";  
  16. }else{  
  17. echo "Could not insert record: ". mysqli_error($conn);  
  18. }  
  19.   
  20. mysqli_close($conn);  
  21. ?>  

Output:

Connected successfully
Record inserted successfully

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) {
    echo "New record created successfully";
} 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)) {
    echo "New record created successfully";
} 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);
    echo "New record created successfully";
    }
catch(PDOException $e)
    {
    echo $sql . "<br>" . $e->getMessage();
    }

$conn = null;
?>
