Source Code
Hi there, In this post you can learn How to select or view data of AJAX CRUD using PHP OOP PDO. So In this tutorial we have discuss how can we view data from Database table. Our Previous tutorial we have make insert. Now we will fecth all row data Dynamically from database table in this CURD system we will learn full Dynamically. we have create DB.php file our previous video we make it in this file we will make a select method and we have already create database connection. so now use this to select data from Database table. I have already create index.php file into table markup. Now we will show data of database table into this table. Now we use jquery ajax reponse, we will send a request to action.php file for load data after that file return data then we show data into front-end page. We used to bootstrap table classes for html markup. Then we will be try to show data without page refresh by using ajax reponse.Any time we load data without page refresh just call our function at the document ready event time. Just simple but advance. So complete our task Now do this and Fellow our video tutorial We have also provide youtube Video in this post. Next video tutorial we will discussing on how to update single row into Mysql Database table by using AJAX response. So please share my post and go to my youtube channel and subscribe and share videos with your friends. Thanks Next Tutorilas Link these:

    • action.php
    • //This file will handle for Select, Insert data to get for insert into Database Table
    • index.php
    • //This file for insert form, view

Sourse Code:

  • DB.php - database connection and query Execute

  • <?php
      class DB{
        public $DBconnect;
        private $hostName = "localhost";
        private $userName = "root";
        private $userPass = "";
        private $DBName = "office_employee";
    
        public function __construct(){
          $this->DBConnection();
        }
    
        public function DBConnection(){
          try{
            $this->DBconnect = new PDO('mysql:host='.$this->hostName.';dbname='.$this->DBName,$this->userName,$this->userPass);
          }catch(PDOException $e){
            echo 'Connection Fail..'.$e->getMessage();
          }
        }
        public function insert($table,$data){
          $keys = implode(',', array_keys($data));
          $values = ":".implode(",:", array_keys($data));
    
          $sql = "INSERT INTO $table($keys) VALUES($values)";
          $stmt = $this->DBconnect->prepare($sql);
    
          foreach ($data as $key => $value) {
            $stmt->bindValue(":$key",$value);
          }
          return $stmt->execute(); 
    
    
        } 
        
        public function select($sql){
          $stmt = $this->DBconnect->prepare($sql);
          $stmt->execute();
          return $stmt->fetchAll(PDO::FETCH_ASSOC);
        }
    
        public function upload($file){
          $extention = explode('.', $file['name']);
          $newName = rand().'.'.$extention[1];
          $destination = './upload/'.$newName;
          move_uploaded_file($file['tmp_name'], $destination);
          return $newName;
    
        }
