How to create event calendar using php?

Welcome to a tutorial on how to build an AJAX-driven events calendar with PHP and MySQL. Looking to add some organizational features to your project? Too many calendars out there that are too complicated?

A simple PHP MySQL calendar only consists of a few key components:

• A database table to store the events.
• A PHP class library to manage the events.
• Lastly, an HTML page to show the calendar of events.

But just how is this done exactly? Let us walk through a step-by-step example in this guide – Read on!

ⓘ I have included a zip file with all the source code at the start of this tutorial, so you don’t have to copy-paste everything… Or if you just want to dive straight in.

DOWNLOAD & NOTES

Firstly, here is the download link to the example code as promised.

QUICK NOTES

• Create a database and import 1-database.sql.
• Change the database settings in 2-cal-lib.php to your own.
• That’s all – Launch 4a-cal-page.php in your browser.

If you spot a bug, feel free to comment below. I try to answer short questions too, but it is one person versus the entire world… If you need answers urgently, please check out my list of websites to get help with programming.

PART 1] EVENTS DATABASE TABLE

1-database.sql

CREATE TABLE `events` [
  `evt_id` bigint[20] NOT NULL,
  `evt_start` datetime NOT NULL,
  `evt_end` datetime NOT NULL,
  `evt_text` text NOT NULL,
  `evt_color` varchar[7] NOT NULL,
  `evt_bg` varchar[7] NOT NULL
] ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
 
ALTER TABLE `events`
  ADD PRIMARY KEY [`evt_id`],
  ADD KEY `evt_start` [`evt_start`],
  ADD KEY `evt_end` [`evt_end`];
 
ALTER TABLE `events`
  MODIFY `evt_id` bigint[20] NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

Let us start by dealing with the foundation of the system – A database table to save all the event entries.
