How to Insert Data into MySQL Database using PHP

Data insert in MySQL Database


Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we are going to be discussing about how to Insert Data into MySQL Database.

Data can be entered into MySQL tables by implementing the SQL INSERT statement through PHP mysql_query function. Below is a simple example to insert a record into an employee table.

Example

Try the following example below to insert a record into employee table -

<?php
   $dbhost = 'localhost:3036';
   $dbuser = 'root';
   $dbpass = 'rootpassword';
   $conn = mysql_connect($dbhost, $dbuser, $dbpass);
   
   if(! $conn ) {
      die('Could not connect: ' . mysql_error());
   }
   
   $sql = 'INSERT INTO employee '.
      '(emp_name,emp_address, emp_salary, join_date) '.
      'VALUES ( "guest", "XYZ", 2000, NOW() )';
      
   mysql_select_db('test_db');
   $retval = mysql_query( $sql, $conn );
   
   if(! $retval ) {
      die('Could not enter data: ' . mysql_error());
   }
   
   echo "Entered data successfully\n";
   
   mysql_close($conn);
?>

In real application, all the values is going to be taken using Html form and those values will be captured using PHP script and they will be inserted into a MySQL tables.


While doing data insert, its best practice to use PHP get_magic_quotes_gpc() function to see if the current configuration for magic quote is set. If it returns false, make use of the addslashes() function to add slashes before quotes.

Example

Try the below example by putting this code below into add_employee.php, this is going to take the input using the Html form and it is going to create records into database -

<html>
   
   <head>
      <title>Add New Record in MySQL Database</title>
   </head>
   
   <body>
      <?php
         if(isset($_POST['add'])) {
            $dbhost = 'localhost:3036';
            $dbuser = 'root';
            $dbpass = 'rootpassword';
            $conn = mysql_connect($dbhost, $dbuser, $dbpass);
            
            if(! $conn ) {
               die('Could not connect: ' . mysql_error());
            }
            
            if(! get_magic_quotes_gpc() ) {
               $emp_name = addslashes ($_POST['emp_name']);
               $emp_address = addslashes ($_POST['emp_address']);
            }else {
               $emp_name = $_POST['emp_name'];
               $emp_address = $_POST['emp_address'];
            }
            
            $emp_salary = $_POST['emp_salary'];
            
            $sql = "INSERT INTO employee ". "(emp_name,emp_address, emp_salary, 
               join_date) ". "VALUES('$emp_name','$emp_address',$emp_salary, NOW())";
               
            mysql_select_db('test_db');
            $retval = mysql_query( $sql, $conn );
            
            if(! $retval ) {
               die('Could not enter data: ' . mysql_error());
            }
            
            echo "Entered data successfully\n";
            
            mysql_close($conn);
         }else {
            ?>
            
               <form method = "post" action = "<?php $_PHP_SELF ?>">
                  <table width = "400" border = "0" cellspacing = "1" 
                     cellpadding = "2">
