Once you have designed the registration form, then you need to create an insert.php file to get from the data and store it in the variables. Once you do that, then you need to write the validation and also query to store the data. I’m going to share with you the insert query.

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)

The insert query helps you to store the record in the database. I’ve mentioned below code that helps to store the record in the database.

<?php

    require_once("connection.php");

    if(isset($_POST['submit']))
    {
        if(empty($_POST['name']) || empty($_POST['email']) || empty($_POST['age']))
        {
            echo ' Please Fill in the Blanks ';
        }
        else
        {
            $UserName = $_POST['name'];
            $UserEmail = $_POST['email'];
            $UserAge = $_POST['age'];

            $query = " insert into records (User_Name, User_Email,User_Age) values('$UserName','$UserEmail','$UserAge')";
            $result = mysqli_query($con,$query);

            if($result)
            {
                header("location:view.php");
            }
            else
            {
                echo '  Please Check Your Query ';
            }
        }
    }
    else
    {
        header("location:index.php");
    }



?>

Once you have followed the above process, then your data has been stored in the database. once you do that, then you are able to display each database data in the HTML tables. Follow on below code, Basically, the Below File Name is View.php, you can write any name.

SELECT * FROM table_name

I’ve mentioned the above code called Select statement which is used to get the data from the database. Then you can store the database data in the PHP local variables, then you can assign the PHP local variable where you want to display the data. you can check out the below-mentioned code.

Here is the update query, inside the update operation, you need to use that. I’m going to share with you the update query that helps you to understand how to update a record using with the help of query.

UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value 

Once you do that, then you are able to perform the operation such as update the record. below, I mentioned below code, you can use that to update the record.

<?php 

    require_once("connection.php");

    if(isset($_POST['update']))
    {
        $UserID = $_GET['ID'];
        $UserName = $_POST['name'];
        $UserEmail = $_POST['email'];
        $UserAge = $_POST['age'];

        $query = " update records set User_Name = '".$UserName."', User_Email='".$UserEmail."',User_Age='".$UserAge."' where User_ID='".$UserID."'";
        $result = mysqli_query($con,$query);

        if($result)
        {
            header("location:view.php");
        }
        else
        {
            echo ' Please Check Your Query ';
        }
    }
    else
    {
        header("location:view.php");
    }


?>

Once you do that, then you are able to perform another operation such as Delete the record. I mentioned below a very simple code, you can follow that to delete the record.

DELETE FROM table_name
WHERE some_column = some_value

Above I’ve mentioned the delete query that helps you to delete the record. I’ve mentioned below the delete code, you can find out the usage of the delete query. I hope you can do that.

if(isset($_GET['Del']))
         {
             $UserID = $_GET['Del'];
             $query = " delete from records where User_ID = '".$UserID."'";
             $result = mysqli_query($con,$query);
             if($result)
             {
                 header("location:view.php");
             }
             else
             {
                 echo ' Please Check Your Query ';
             }
        }
         else
         {
             header("location:view.php");
         }
