PHP OOPS - Insert Data into MySql Database



In this post you can learn how to use PHP Object Oriented Programming for Insert or Add data or item into MySql Table. If you are using OOPS in PHP then it will be become very simple to use and can do such function like Add or Insert data into mysql table. In this post you can find I have make one PHP Class for Inserting Item into Mysql table. I have use __construct() megic methods of PHP for making database connection. In This PHP Megic method whenever new object of class will created then which ever code run under this method it will run, So I have write Mysql Database connection code write under this __construct() method.

I have provide complete source code with PHP Programming video tutorial with this post. You find source code below and video tutorial on above the post.

Source Code

Table - tbl_posts


 --  
 -- Table structure for table `tbl_posts`  
 --  
 CREATE TABLE IF NOT EXISTS `tbl_posts` (  
  `post_id` int(11) NOT NULL AUTO_INCREMENT,  
  `post_title` varchar(150) NOT NULL,  
  `post_desc` text NOT NULL,  
  PRIMARY KEY (`post_id`)  
 ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;  
 --  
 -- Dumping data for table `tbl_posts`  
 --  

Class - database.php


 <?php   
 //database.php  
 class Databases{  
      public $con;  
      public $error;  
      public function __construct()  
      {  
           $this->con = mysqli_connect("localhost", "root", "", "testing");  
           if(!$this->con)  
           {  
                echo 'Database Connection Error ' . mysqli_connect_error($this->con);  
           }  
      }  
      public function insert($table_name, $data)  
      {  
           $string = "INSERT INTO ".$table_name." (";            
           $string .= implode(",", array_keys($data)) . ') VALUES (';            
           $string .= "'" . implode("','", array_values($data)) . "')";  
           if(mysqli_query($this->con, $string))  
           {  
                return true;  
           }  
           else  
           {  
                echo mysqli_error($this->con);  
           }  
      }  
 }  
 ?>  

For Insert Data - test_class.php


 <?php  
 //test_class.php  
 include 'database.php';  
 $data = new Databases;  
 $success_message = '';  
 if(isset($_POST["submit"]))  
 {  
      $insert_data = array(  
           'post_title'     =>     mysqli_real_escape_string($data->con, $_POST['post_title']),  
           'post_desc'          =>     mysqli_real_escape_string($data->con, $_POST['post_desc'])  
      );  
      if($data->insert('tbl_posts', $insert_data))  
      {  
           $success_message = 'Post Inserted';  
      }       
 }  
 ?>
