         if(isset($_POST[''add''])) {
            $dbhost = ''localhost
            $dbuser = ''root
            $dbpass = ''root@123
            $conn = mysqli_connect($dbhost, $dbuser, $dbpass);
         
            if(! $conn ) {
               die(''Could not connect: '' . mysqli_error($conn));
            }
            if(! get_magic_quotes_gpc() ) {
               $tutorial_title = addslashes ($_POST[''tutorial_title'']);
               $tutorial_author = addslashes ($_POST[''tutorial_author'']);
            } else {
               $tutorial_title = $_POST[''tutorial_title''];
               $tutorial_author = $_POST[''tutorial_author''];
            }
            $submission_date = $_POST[''submission_date''];
            $sql = "INSERT INTO tutorials_tbl ".
               "(tutorial_title,tutorial_author, submission_date) "."VALUES ".
               "(''$tutorial_title'',''$tutorial_author'',''$submission_date'')";
            mysqli_select_db( $conn, ''TUTORIALS'' );
            $retval = mysqli_query( $conn, $sql );
         
            if(! $retval ) {
               die(''Could not enter data: '' . mysqli_error($conn));
            }
            echo "Entered data successfullyn";
            mysqli_close($conn);
         } else {
      ?>  
      <form method = "post" action = "<?php $_PHP_SELF ?>">
         <table width = "600" border = "0" cellspacing = "1" cellpadding = "2">
            <tr>
               <td width = "250">Tutorial Title</td>
               <td><input name = "tutorial_title" type = "text" id = "tutorial_title"></td>
            </tr>         
            <tr>
               <td width = "250">Tutorial Author</td>
               <td><input name = "tutorial_author" type = "text" id = "tutorial_author"></td>
            </tr>

               <td width = "250">Submission Date [   yyyy-mm-dd ]</td>
               <td><input name = "submission_date" type = "text" id = "submission_date"></td>
            </tr>      
            <tr>
               <td width = "250"> </td>
               <td></td>
            </tr>         
            <tr>
               <td width = "250"> </td>
               <td><input name = "add" type = "submit" id = "add"  value = "Add Tutorial"></td>
            </tr>
         </table>
      </form>
   <?php
      }
   ?>
   </body>
</html>

Output

Access the mysql_example.php deployed on apache web server, enter details and verify the output on submitting the form.

Entered data successfully

While doing a data insert, it is best to use the function get_magic_quotes_gpc() to check if the current configuration for magic quote is set or not. If this function returns false, then use the function addslashes() to add slashes before the quotes.

You can put many validations around to check if the entered data is correct or not and can take the appropriate action.
