PHP MySQL INSERT Query

In this tutorial you will learn how to insert records in a MySQL table using PHP.

Inserting Data into a MySQL Database Table

Now that you’ve understood how to create database and tables in MySQL. In this tutorial you will learn how to execute SQL query to insert records into a table.

The INSERT INTO statement is used to insert new rows in a database table.

Let’s make a SQL query using the INSERT INTO statement with appropriate values, after that we will execute this insert query through passing it to the PHP mysqli_query() function to insert data in table. Here’s an example, which insert a new row to the persons table by specifying values for the first_name, last_name and email fields.

Example

 // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('Peter', 'Parker', 'peterparker@mail.com')"; if(mysqli_query($link, $sql)) < echo "Records inserted successfully."; >else < echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); >// Close connection mysqli_close($link); ?>

connect_error); > // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('Peter', 'Parker', 'peterparker@mail.com')"; if($mysqli->query($sql) === true) < echo "Records inserted successfully."; >else< echo "ERROR: Could not able to execute $sql. " . $mysqli->error; > // Close connection $mysqli->close(); ?>

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); > catch(PDOException $e)< die("ERROR: Could not connect. " . $e->getMessage()); > // Attempt insert query execution try< $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('Peter', 'Parker', 'peterparker@mail.com')"; $pdo->exec($sql); echo "Records inserted successfully."; > catch(PDOException $e)< die("ERROR: Could not able to execute $sql. " . $e->getMessage()); > // Close connection unset($pdo); ?>

If you remember from the preceding chapter, the id field was marked with the AUTO_INCREMENT flag. This modifier tells the MySQL to automatically assign a value to this field if it is left unspecified, by incrementing the previous value by 1.

Inserting Multiple Rows into a Table

You can also insert multiple rows into a table with a single insert query at once. To do this, include multiple lists of column values within the INSERT INTO statement, where column values for each row must be enclosed within parentheses and separated by a comma.

Let’s insert few more rows into the persons table, like this:

Example

 // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('John', 'Rambo', 'johnrambo@mail.com'), ('Clark', 'Kent', 'clarkkent@mail.com'), ('John', 'Carter', 'johncarter@mail.com'), ('Harry', 'Potter', 'harrypotter@mail.com')"; if(mysqli_query($link, $sql)) < echo "Records added successfully."; >else < echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); >// Close connection mysqli_close($link); ?>

connect_error); > // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('John', 'Rambo', 'johnrambo@mail.com'), ('Clark', 'Kent', 'clarkkent@mail.com'), ('John', 'Carter', 'johncarter@mail.com'), ('Harry', 'Potter', 'harrypotter@mail.com')"; if($mysqli->query($sql) === true) < echo "Records inserted successfully."; >else< echo "ERROR: Could not able to execute $sql. " . $mysqli->error; > // Close connection $mysqli->close(); ?>

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); > catch(PDOException $e)< die("ERROR: Could not connect. " . $e->getMessage()); > // Attempt insert query execution try< $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('John', 'Rambo', 'johnrambo@mail.com'), ('Clark', 'Kent', 'clarkkent@mail.com'), ('John', 'Carter', 'johncarter@mail.com'), ('Harry', 'Potter', 'harrypotter@mail.com')"; $pdo->exec($sql); echo "Records inserted successfully."; > catch(PDOException $e)< die("ERROR: Could not able to execute $sql. " . $e->getMessage()); > // Close connection unset($pdo); ?>

Now, go to phpMyAdmin ( http://localhost/phpmyadmin/ ) and check out the persons table data inside demo database. You will find the value for the id column is assigned automatically by incrementing the value of previous id by 1.

Note: Any number of line breaks may occur within a SQL statement, provided that any line break does not break off keywords, values, expression, etc.

Insert Data into a Database from an HTML Form

In the previous section, we have learned how to insert data into database from a PHP script. Now, we’ll see how we can insert data into database obtained from an HTML form. Let’s create an HTML form that can be used to insert new records to persons table.

Step 1: Creating the HTML Form

Here’s a simple HTML form that has three text fields and a submit button.

Example

        
First Name: 
Last Name: 
Email Address:  

Step 2: Retrieving and Inserting the Form Data

When a user clicks the submit button of the add record HTML form, in the example above, the form data is sent to ‘insert.php’ file. The ‘insert.php’ file connects to the MySQL database server, retrieves forms fields using the PHP $_REQUEST variables and finally execute the insert query to add the records. Here is the complete code of our ‘insert.php’ file:

Example

 // Escape user inputs for security $first_name = mysqli_real_escape_string($link, $_REQUEST['first_name']); $last_name = mysqli_real_escape_string($link, $_REQUEST['last_name']); $email = mysqli_real_escape_string($link, $_REQUEST['email']); // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('$first_name', '$last_name', '$email')"; if(mysqli_query($link, $sql)) < echo "Records added successfully."; >else < echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); >// Close connection mysqli_close($link); ?>

connect_error); > // Escape user inputs for security $first_name = $mysqli->real_escape_string($_REQUEST['first_name']); $last_name = $mysqli->real_escape_string($_REQUEST['last_name']); $email = $mysqli->real_escape_string($_REQUEST['email']); // Attempt insert query execution $sql = "INSERT INTO persons (first_name, last_name, email) VALUES ('$first_name', '$last_name', '$email')"; if($mysqli->query($sql) === true) < echo "Records inserted successfully."; >else< echo "ERROR: Could not able to execute $sql. " . $mysqli->error; > // Close connection $mysqli->close(); ?>

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); > catch(PDOException $e)< die("ERROR: Could not connect. " . $e->getMessage()); > // Attempt insert query execution try< // Create prepared statement $sql = "INSERT INTO persons (first_name, last_name, email) VALUES (:first_name, :last_name, :email)"; $stmt = $pdo->prepare($sql); // Bind parameters to statement $stmt->bindParam(':first_name', $_REQUEST['first_name']); $stmt->bindParam(':last_name', $_REQUEST['last_name']); $stmt->bindParam(':email', $_REQUEST['email']); // Execute the prepared statement $stmt->execute(); echo "Records inserted successfully."; > catch(PDOException $e)< die("ERROR: Could not able to execute $sql. " . $e->getMessage()); > // Close connection unset($pdo); ?>

In the next chapter we will extend this insert query example and take it one step further by implementing the prepared statement for better security and performance.

Note: The mysqli_real_escape_string() function escapes special characters in a string and create a legal SQL string to provide security against SQL injection.

This is very basic example of inserting the form data in a MySQL database table. You can extend this example and make it more interactive by adding validations to the user inputs before inserting it to the database tables.
