In this tutorial we will create a Add Days To Date Using PHP. PHP is a server-side scripting language designed primarily for web development. PHP is a server-side scripting language designed primarily for web development. It is mostly used by a newly coders for its user friendly environment. So let's now do the coding...

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And this is the link for the jquery that i used in this tutorial https://jquery.com/. Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_date, after that click Import then locate the database file inside the folder of the application then click ok. tut1

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
        $conn = new mysqli('localhost', 'root', '', 'db_date');
        
        if(!$conn){
                die("Error: Failed to connect to database");
        }
 
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

Creating PHP Query

This code contains the php query of the application. This code contains to methods. It can store the data inputs to the database server and it can also add days to a specific date of events. To do that just copy and write this block of codes inside the text editor, then save it as shown below. save_event.php

<?php
        require_once 'conn.php';
        date_default_timezone_set("Etc/GMT-8");
        
        if(ISSET($_POST['save'])){
                $event = $_POST['event'];
                $date = $_POST['date']." ".date("h:i:s");
                
                $conn->query("INSERT INTO `event` VALUES('', '$event', '$date')") or die($conn->error());
                
                echo "<script>alert('Data Inserted')</script>";
                echo "<script>window.location = 'index.php'</script>";
        }
?>

add_day.php

<?php
        require_once 'conn.php';
        
        date_default_timezone_set("Etc/GMT-8");
        
        if(ISSET($_POST['add'])){
                $event_id = $_POST['event_id'];
                $day = $_POST['day'];
                
                $query = $conn->query("SELECT * FROM `event` WHERE `event_id` = '$event_id'") or die($conn->error());
                $fetch = $query->fetch_array();
                
                $date = date("Y-m-d h:s:i", strtotime("+".$day." DAY".$fetch['date']));
                
                $conn->query("UPDATE `event` SET `date` = '$date' WHERE `event_id` = '$event_id'") or die($conn->error());
                
                echo "<script>alert('Days Added')</script>";
                echo "<script>window.location = 'index.php'</script>";
        }
?>
