How To Insert Update Delete In Php On Same Page Using Ajax And Update Table In PHP.

  • Step 1 – Create a Database
  • Step 2 – Connecting To Database using PHP
  • Step 3 – Retrieve All Data From Database and Display in HTML Table
  • Step 4 – Edit Data From Database
  • Step 5 – Insert and Update Data Into Database
  • Step 6 – Delete Data From Database

Step 1 – Create Database

In this step, Open your browser and connect to your PHPMyAdmin. Then run the following query to create database and table:

CREATE DATABASE demo;
CREATE TABLE `users` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `name` VARCHAR(255) NULL DEFAULT NULL, `age` VARCHAR(255) NULL DEFAULT NULL, `email` VARCHAR(255) NULL DEFAULT NULL, `created` DATETIME NULL DEFAULT NULL, PRIMARY KEY (`id`) ) COLLATE = 'latin1_swedish_ci' ENGINE = InnoDB AUTO_INCREMENT = 1;
INSERT INTO
   `users` (`id`, `name`, `age`, `email`, `created`) 
VALUES
   (
      NULL, 'ajay', '27', '[email protected]', NULL
   )
, 
   (
      NULL, 'abhay', '23', '[email protected]', NULL
   )
;

Step 2 – Connecting To Database Using PHP

This step creates one file name db.php, which is used to connect the project from the database: Then add the following code in below:

<?php
 
    $hName='localhost'; // host name
 
    $uName='root';   // database user name
 
    $password='';   // database password
 
    $dbName = "demo"; // database name
 
    $dbCon = mysqli_connect($hName,$uName,$password,"$dbName");
 
      if(!$dbCon){
          die('Could not Connect MySql Server:' .mysql_error());
      }
?>

Step 3 – Retrieve All Data From Database And Display In HTML Table

In this step, you need to create an Index.php file and add the following code below:

index.php file code will display all user's lists from the database. And as well as insert and edit data from MySQL database using the bootstrap model and ajax.

                $.ajax({

                    data: {
                        id: id
                    },
                    dataType: 'json',
                    success: function(res) {
                        $('#name').html(res.name);
                        $('#age').html(res.age);
                        $('#email').html(res.email);
                        window.location.reload();
                    }

        $('#userInserUpdateForm').submit(function() {
            // ajax
            $.ajax({
                type: "POST",

            });
        });
    }); <
</script>
   </body>
</html>

Step 4 – Edit Data From Database

In this step, Create an edit.php file to get single record data from the MySQL database. So, add the following code into edit.php:

<?php
include "db.php";
$id = $_POST['id'];
$query="SELECT * from users WHERE id = '" . $id . "'";
$result = mysqli_query($dbCon,$query);
$data= mysqli_fetch_array($result);
if($data) {
echo json_encode($data);
} else {
echo "Error: " . $sql . "" . mysqli_error($dbCon);
}
?>

Step 5 – Insert And Update Data Into Database

In this step, insert and add data from the MySQL database update table in php. So, Create an insert-update.php file to insert and update record data from the MySQL database. So, add the following code into insert-update.php:

<?php
if(count($_POST)>0)
{    
include 'db.php';
$name = $_POST['name'];
$age = $_POST['age'];
$email = $_POST['email'];
if(empty($_POST['id'])){
$query = "INSERT INTO users (name,age,email)
VALUES ('$name','$age','$email')";
}else{
$query = "UPDATE users set id='" . $_POST['id'] . "', name='" . $_POST['name'] . "', age='" . $_POST['age'] . "', email='" . $_POST['email'] . "' WHERE id='" . $_POST['id'] . "'"; 
}
$res = mysqli_query($dbCon, $query);
if($res) {
echo json_encode($res);
} else {
echo "Error: " . $sql . "" . mysqli_error($dbCon);
}
}
?>

Step 6 – Delete Data From Database

In This Final step, PHP inserts update deletes data from the MySQL database. So, create delete.php file, which is delete data from mysql database. Now you need to add the following code into the delete.php file:

<?php
include 'db.php';
$id = $_POST['id'];
$query = "DELETE FROM users WHERE id='" . $id . "'";
$res = mysqli_query($dbCon, $query);
if($res) {
echo json_encode($res);
} else {
echo "Error: " . $sql . "" . mysqli_error($dbCon);
}
?>
