This pattern allows information to be retrieved, inserted, and updated in your database with minimal scripting. In some cases only one or two lines of code are necessary to perform a database action. CodeIgniter does not require that each database table be its own class file. It instead provides a more simplified interface. Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications, since the query syntax is generated by each database adapter. It also allows for safer queries, since the values are escaped automatically by the system. Note: If you intend to write your own queries you can disable this class in your database config file, allowing the core database library and adapter to utilize fewer resources. Note: If you are using PHP 5 you can use method chaining for more compact syntax. This is described at the end of the page.
Fullcalendar with PHP and CodeIgniter – Adding Events – Part 3
If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable. CodeIgniter User Guide Version 2. Change Log Version 2. Version 2.
Some time ago, a client called me and asked me to tell him when someone had logged in and out of the network. It was a reasonable request but it presented a challenge for which I had to develop a quick solution. In developing the application, I made use of a PHP language framework, called CodeIgniter, that I have been using successfully for my development project. The purpose of this article is to show you how I solved the problem and, at the same time, introduce you to CodeIgniter, a lightweight, easy to use PHP framework that you can use to build high quality, robust, PHP web sites and applications.
On its face, the problem does not seem to be that difficult. After all, all you should have to do is check the security event log on the server to retrieve the requested information. There are, unfortunately, two problems with that approach:. Given the nature of the problem, the solution seemed to be to write something simple.

When used together, they form a powerful foundation for rapidly developing usable Web sites and applications. This article shows how to integrate these two systems into a single framework and how to use jQuery to improve the UI of an existing Web application. It assumes that you have both CodeIgniter version 1.

PHP – Date Of Birth Validation In Codeigniter
Mike Mukul. The future of CodeIgniter is anything but clear. As rival frameworks, especially Laraval, grew, many were sounding the death bells for CodeIgniter. However, CodeIgniter is back with a new version. Used by many developers, it gained popularity because of its easy implementation and low-learning curve for beginners.
I ran into an issue using a function that loops through an array of dates where the keys to the array are the Unix timestamp for midnight for each date. The loop.
Vicario i think its also possible with ‘regex’. It’s impossible to implement reliable date validation with regular expressions. Yours is actually quite good but, for instance, it claims that is not valid. Yeah, right, if you have the patience you can probably hard-code all the exceptions including missing days due to transition to Gregorian calendar but you know what I mean: regular expressions are not the best tool. I think this is the way to go too.
One thing, the name of the function has to be without “callback”. Using proper date functions is the way to go. Nice answer. I know this is old, but I just encountered the same issue. I like the answer Winks provided, but found that the code did not work. I modified it to this:. This file should look like this:. I have a pretty clean solution for this.
Returns the current time as a Unix timestamp, referenced either to your server’s local time or GMT, based on the “time reference” setting in your config file. If you do not intend to set your master time reference to GMT which you’ll typically do if you run a site that lets each user set their own timezone settings there is no benefit to using this function over PHP’s time function. The benefit of doing dates this way is that you don’t have to worry about escaping any characters that are not date codes, as you would normally have to do with the date function.
There is no builtin date validation in Codeigniter form_validation Library, but you can use its callback to call a function and validate the date.
There are several ways that a new Time instance can be created. The first is simply to create a new instance like any other class. When you do it this way, you can pass in a string representing the desired time. You can pass in strings representing the timezone and the locale in the second and parameters, respectively.
If no locale or timezone is provided, the application defaults will be used. The Time class has several helper methods to instantiate the class.
Creating a Robust Web Application with PHP and CodeIgniter
A controller is a simple class file. As the name suggests, it controls the whole application by URI. You will find two files there, index. These files come with the CodeIgniter.

Comment 0. The CodeIgniter calendar class is available for creating data-driven calendars for your web apps. What follows is a walk through on how I implemented the calendar class for a simple tasks web app. So, the app I wanted was a simple list of tasks that could be checked off when completed and a way to keep some notes for the task too. It would be useful if you know the basics of CodeIgniter too.
All of the above are standard CodeIgniter set up operations. The user guide will help you out. The calendar I wanted was a month display, with the ability to click through other months with a simple hyperlink. I also wanted to attach a link to tasks stored in the database on the individual days of the month. To get the basic calendar working, we can get some setting up done on the constructor of the welcome controller:.
Here, we are setting up some preferences and passing them to the calendar class. We want the next and previous links, and they will need a URL to operate on.
