Edit Report a Bug. 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 starts at the first timestamp, then incremented by adding seconds ie. However, Daylight Saving Time threw off the accuracy of this loop, since certain days have a duration other than seconds. I worked around it by adding a couple of lines to force the timestamp to midnight at each interval. The following script will do the conversion either way. If you give it a numeric timestamp, it will display the corresponding date and time. If you give it a date and time in almost any standard format , it will display the timestamp.
How to change date format in PHP Codeigniter?
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.

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. In addition, you need the jQuery library version 1. One of the most important aspects of Web 2. Specifically, interaction with the Web page doesn’t require “visual communication” with the Web server—for example, click Submit, wait for the Web server to process the submitted information, then the entire Web page refreshes with updated content.
Instead, only the content that needs to change is updated, while the rest of the page remains in place. This “submission-less” process works through the use of Ajax, which lets Web developers transmit information between a Web client browser and a Web server without requiring page refreshes. Better yet, this information transfer can be triggered without any direct user intervention. When a Web page uses Ajax, it is asynchronously sending data to and receiving data from a Web server.
Fetch records between date range using Codeigniter active record
The time can be formatted with or without seconds, and it can be set to European or US format. If only the timestamp is submitted it will return the time without seconds formatted for the U. This function can take a number poorly-formed date formats and convert them into something useful. It also accepts well-formed dates. The function will return a UNIX timestamp by default. You can, optionally, pass a format string the same type as the PHP date function accepts as the second parameter.

Codeigniter Date Helper : Codeigniter provides the helper which is used to work with dates. Here in this tutorial we are going to explain how you can use date helper in Codeigniter. You can use our online editor run and see the output of the example. This function is somehow similar to the date function. In addition it enables you to use this function in mysql style date function. Necessary cookies are absolutely essential for the website to function properly.

CodeIgniter – Basic Concepts
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.
By leveraging the power of CodeIgniter’s MVC-based framework and from a list of board-approved options and schedules a date for each.
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. Keep these files as they are. This class must be extended whenever you want to make your own Controller class. This indicates the class name of controller. The class name must start with uppercase letter but we need to write lowercase letter when we call that controller by URI.
After visiting the first URI in the browser, we get the output as shown in the picture given below. We have used only controller name in the URI.
Retrieve, Insert, Update and Delete Functionality in Codeigniter
PHP date_default_timezone_set() function is used to sets the default timezone used by all date or time functions. In CodeIgniter, the best place.
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. Updated timezones in Date Helper.
The Encrypt Class now requires the Mcrypt extension to be installed. Bug fixes for 2. Fixed a bug – PDO Database driver didn’t properly check for query failures. Fixed a bug in the Session Library where authentication was not performed for encrypted cookies. Fixed a bug – Migrations Library configuration file was mistakenly using Windows style line feeds. Added support for IPv6 to the Input Library.
You can now use any string as the word delimiter.

Data is the bloodline of most applications. The data needs to be stored in such a way that it can be further analyzed to provide insights and facilitate business decisions. The data is usually stored in the database. Among the chief concerns when interacting with the database is security, ease of access and database vendor specific implementations of Structured Query Language SQL. Active record is a design pattern that makes it easy to interact with the database in ease, secure and eloquent way.
The active record has the following advantages Insert, update and delete records with simple method chains of active record Submits the user input in a secure way using parameters Allows you to work with multiple database engines such as MySQL, SQL Server, etc. We will have two tables, one with orders the other with details. This tutorial assumes you have MySQL database installed up and running. CodeIgniter Database Configuration We will now configure our application to be able to communicate with this database.
Now that we have successfully created the controller method for active record, we will now need to create a route that we will call to execute the controller method. Now open routes.
Laravel vs CodeIgniter: Which is Better?
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.
The first parameter must contain the format, the second parameter must contain the date as a Unix timestamp. Takes a Unix timestamp referenced to GMT as input, and converts it to a localized timestamp based on the timezone and Daylight Saving time submitted. The time can be formatted with or without seconds, and it can be set to European or US format.
CodeIgniter does not require that each database table be its own class file. date’); $query = $this->db->get(‘mytable’); // Executes: SELECT title, content, date.
Tutorial Knowledge-Base Awesome. Why and how to solve it? Asked By Me hdi. Codeigniter database date-compare Im having a problem comparing dates in a database to a week from now using activerecord.

Codeigniter – Date format – Form Validation
I have a pretty clean solution for this. You can extend codeigniters form validation library. This file should look like this:. Then in your controller you use this as any other form validation function like for example ‘required’. 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.
The CodeIgniter calendar class is available for creating data-driven calendars for If it’s not, we use the date function to get the current month.
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. The first of these is the now method that returns a new instance set to the current time.
CodeIgniter and Ajax using jQuery
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”.
complete my dating., Developers who can read the project, and give a summary of what he/she understand, the framework is CodeIgniter.
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.
