In this post you can know about crud operation in PHP inserting, editing, Updating and Deleting in a single page.
User can save a dynamic data or content in a database and show the data on web page, user can also deleting a any of data from database and also editing or updating a data from a single page.
First create a database name crud and create a table name = data\
- id - int(18)
- name - varchar(200)
- address - varchar(200)
- mobile_number - varchar(200)
Then Create database connectivity file = db.php
db.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "crud";
// Create connection
$conn = mysqli_connect($servername,$username,$password,"$dbname");
if (!$conn) {
die("Could Not Connect:" .mysqli_connect_error());
}
?>Now Create index.php for show data, For inserting data, editing data, updating data, deleting data
Index.php
<?php
include 'all_process.php';
if (isset($_GET['edit'])) {
$id = $_GET['edit'];
$edit_state = true;
$record = mysqli_query($conn, "SELECT * FROM data WHERE id=$id");
$data = mysqli_fetch_array($record);
$name = $data['name'];
$address = $data['address'];
$mobile_number = $data['mobile_number'];
}
?>

<?php
$i++;

</html>Now Create a all_process.php file for back process for deleting or updating and inserting.
all_process.php
<?php
session_start();
include_once 'db.php';
$name = "";
$address = "";
$mobile_number = "";
$id = 0;
$edit_state = false;
if (isset($_POST['save'])) {
$name = $_POST['name'];
$address = $_POST['address'];
$mobile_number = $_POST['mobile_number'];
$sql = "INSERT INTO data (name,address,mobile_number) VALUES ('$name','$address','$mobile_number')";
if (mysqli_query($conn, $sql)) {
$_SESSION['message'] = "Data Saved Successfully";
header("Location: index.php");
} else {
mysqli_close($conn);
}
}
// For updating records
if (isset($_POST['update'])) {
$id = $_POST['id'];
$name = $_POST['name'];
$address = $_POST['address'];
$mobile_number = $_POST['mobile_number'];
mysqli_query($conn, "UPDATE data SET name='$name', address='$address', mobile_number='$mobile_number' WHERE id=$id");
$_SESSION['message'] = "Data Updated Successfully";
header('location: index.php');
}
// For deleteing records
if (isset($_GET['delete'])) {
$id = $_GET['delete'];
mysqli_query($conn, "DELETE FROM data WHERE id=$id");
$_SESSION['message'] = "Data Deleted Successfully";
header('location:index.php');
}
