jQuery - Page Redirect after X seconds wait

You must have come across any website which uses a webpage with some annoying advertisement and a message that says “You will be redirected to actual page after X seconds”. This can be easily implemented with jQuery. In this post, find jQuery code to redirect user to another webpage after specific time interval or few seconds.

The below jQuery code uses JavaScript setInterval which executes a function, over and over again, at specified time intervals. So all is required is to set the setInterval as 1 second and then minus the counter from actual time interval. When it reach to zero second , simply redirect to specific path.

HTML Code

<h1>You will be redirect to actual page after <span id="spnSeconds">10</span> seconds.</h1>

CSS Code

body {
font-size:12pt;
font-family:Calibri;
}
#spnSeconds {
font-size:25pt;
color:Red;
}

Jquery Code

$(document).ready(function () {
window.setInterval(function () {
var iTimeRemaining = $("#spnSeconds").html();
iTimeRemaining = eval(iTimeRemaining);
if (iTimeRemaining == 0) {
location.href = "http://paceinfonet.org/jquery-page-redirect-after-x-seconds-wait/";
} else {
$("#spnSeconds").html(iTimeRemaining - 1);
}
}, 1000);
});

Understanding Model View Controller in Asp.Net MVC

The Model-View-Controller (MVC) pattern was introduced in 1970s. It is a software design pattern that splits an application into three main aspects : Model, View and Controller. Moreover, MVC pattern forces a separation of concerns within an application for example, separating data access logic and business logic from the UI.

Model

The Model represents a set of classes that describes the business logic and data. It also defines business rules for how the data can be changed and manipulated.

Moreover, models in Asp.Net MVC, handles the Data Access Layer by using ORM tools like Entity Framework or NHibernate etc. By default, models are stored in the Models folder of the project.

View

The View is responsible for transforming a model or models into UI. The Model is responsible for providing all the required business logic and validation to the view. The view is only responsible for displaying the data, that is received from the controller as the result.

Moreover, views in Asp.Net MVC, handles the UI presentation of data as the result of a request received by a controller. By default, views are stored in the Views folder of the project.

Controller

The Controller is responsible for controlling the application logic and acts as the coordinator between the View and the Model. The Controller receive input from users via the View, then process the user’s data with the help of Model and passing the results back to the View.

Moreover, controllers in Asp.Net MVC, respond to HTTP requests and determine the action to take based upon the content of the incoming request. By default, controllers are stored in the Controllers folder of the project.

Platform Features

There are specific features that WordPress offers that make it a unique platform for both websites and blogging. Most of these features are generated by third-party coding that can be modified or extended to meet the needs of any project. The features include:

● No Rebuilding – Any changes made to a template are immediately recognized on the site without the need to regenerate any dynamic or static page.

● WordPress Theme Design And Development – Many third-party companies develop highly creative WordPress themes to create a variety of professional sites, for all types of niche markets. These creative templates optimize web design to the owner’s liking.

● Cross-Communication Tools – The platform utilizes the best cross communication tools to allow website owners instant updates on social media channels when posting to their blog or site.

● Password Protection – Every post is password protected allowing the site owner complete confidentiality in a private post that can only be viewed by the author, until publicly published.

● Comment Capabilities – The platform allows site owners to insert a comment section where visitors can leave feedback and comments. This feature can be enabled or disabled by the site owner.

WordPress offers significant features, plug-ins, add-ons, and themes that are unavailable from its competitors. Any business that is about to design a new website, or renovating an existing one, should consider WordPress as their number one choice. The ability to transfer the site to any hosting location makes WordPress the best solution to develop and maintain a premium site.

significant advantages to using WordPress over the competition

There are significant advantages to using WordPress over the competition. These advantages include:

● Enhanced SEO – With a dedicated built-in SEO platform, WordPress can quickly utilize all of the page elements including meta-tags and meta-descriptions to rank higher in search engine results. Web designers do not necessarily provide SEO options. However, in WordPress it is automatic.

● an extensive list of add-ons and plug-ins – With a seemingly unlimited amount of add-ons and plug-ins, WordPress offers nearly every type of feature from contact forms, to check out and shopping carts, and more. Every time there is a new version or update of WordPress, all plug-ins and add-ons are automatically updated too.

● Extremely affordable – Compared all the other competition available online, WordPress is much less expensive to operate and maintain. With a fully customizable, easy to install CMS, site owners can use all the benefits to develop the best dynamic or static website.

● Quick and easy indexing – WordPress utilizes the best indexing tools available. It optimizes the search engine’s abilities to index and file pages and content. Generally, any site that utilizes CMS technology will automatically be indexed much quicker in the search engines than an old-fashioned, static website.

● No coding skills required – The CMS is designed to be simple enough that no coding skills are required to develop or maintain the website. This means the site owner can quickly upload newly developed content whenever desired without the need to hire a web designer to perform the duties instead.

● Online Marketing – A WordPress site can be promoted for free. Online promotional tools include sending the site to free blog directories.

● A built-in blogging platform – WordPress was originally designed as a blogging platform. Because of this it automatically has the best features, plug-ins and add-ons. Many websites incorporate a blog as a way to communicate with their customers, patients, ans, volunteers, and staff.

● A transferable framework – Businesses wishing to stay within their budget when using a host provider to handle their online website enjoy the freedom WordPress provides with its transferable framework.

● Built-in RSS feed – Website owners can quickly syndicate all the content on their site, through an RSS feed. Designed as an extremely powerful traffic magnetizing tool, the RSS feed distributes company information out to the Internet while pulling an audience toward the site.

● Ongoing Support – Because WordPress is used by over 75 million site owners around the world, they offer the best ongoing support. Their support system includes tutorials, forums and a backup of other websites that are all available to answer all pertinent and important questions for the novice or expert user.

● Full Compatibility – They also provide extensive backwards compatibility, offering peace of mind when upgrading the system to a newer version, to allow better flexibility and safeguards. WordPress is known for not having migration issues.

10 Must-Have WordPress Plugins for Your Business Website

1. Content Aware Sidebars  

If you’ve used other content management systems such as Joomla, you’ll quickly find the need to assign widgets to specific pages or posts only. There is no way to do such a thing in WordPress out of the box.

That’s where the Content Aware Sidebars plugin comes in handy. It allows you to create an unlimited number of sidebars (widget areas) for any widget area and assign it to specific pages, posts, categories, and so on. In a nutshell, it basically creates a virtual widget area that replaces the real widget area for the pages you specify.

Once you create a new sidebar, it will show up in the Appearance -> Widgets with all other widget areas.

2. Enhanced Text Widget

The out of the box text widget that comes with WordPress is useful, but it lacks many important and necessary features.

The Enhanced Text Widget is a free plugin that enables a more feature-rich text widget for your use. Some of the features supported by the widget include:

    It allows you to hide or show the widget title

    Turn your widget title into a link

    Assign CSS classes to the widget

    Supports text, HTML, PHP, Flash, JavaScript, and Shortcodes

3. BackupBuddy

Every business that has a website needs to have a way to back up that website on a regular basis. Website backups should be secure and restorable in a short period of time. That it exactly what BackupBuddy does.

BackupBuddy allows you to create full or partial backups of your WordPress website including core WordPress, database, and all plugins. It even allows you to schedule regular backups and store them in various locations such as local hosting, Amazon S3, FTP, Dropbox, or BackupBuddy Stash.

This is the most comprehensive backup plugin for WordPress and it literally has hundreds of useful features that will come in handy. The best part is that you can restore any backup in a matter of minutes.

BackupBuddy will run you $80 for 2 licenses, $100 for 10 licenses, $150 for unlimited licenses, or $197 for developer license for BackupBuddy and all other iThemes plugins. Although the prices seem a bit on the expensive side, you’ll be happy you paid it when your website is corrupted or gets hacked and you find yourself needing to restore it quickly.

4. WordPress SEO by Yoast

WordPress SEO by Yoast is bar none the best SEO plugin for WordPress. It allows complete control of page titles and meta descriptions on a per page/post basis as well as for each taxonomy (category or tag pages).

Some other useful features include 301 redirection and setting up rules for search engine robots such as follow, nofollow, index, noindex, and so on. It also allows you to customize the Facebook and Google+ descriptions for individual pages or posts in case you don’t want to use the default meta description field.

One thing you won’t have to worry about anymore is the rel=“canonical” tag because the WordPress SEO plugin automatically adds it to every page and post. So you can be sure that Google won’t penalize your website for duplicate content due to dynamic URL string variations.

5. Akismet

Although there are many plugins that help you combat spam, Akismet is one of the best options because it comes with WordPress out of the box and it’s free for personal use.

Setting up Akismet is a piece of cake. All you have to do is go to Akismet.com and register to get a WordPress key. Once you’re assigned a key, you can insert it in the Akismet settings on your website and say goodbye to spam!

6. Visual Composer for WordPress

WordPress can be limiting to the average users when it comes to how you want your page layout to look. Even though you can do anything with HTML and CSS, most users do not know these coding languages. That’s where Visual Composer for WordPress can help.

Visual Composer transforms the default WordPress page editor into a robust feature-rich editor that allows you to add columns, image galleries, accordions, tour sections, call-to-action buttons, videos, and much more.

Visual Composer can be hard to find because the only place where you can purchase it is Code Canyon.

7. Gravity Forms

Every website that intends to generate revenue needs to utilize forms. Forms allow us to collect information from our users, which we later use to provide services to them.

There are many WordPress form plugins, but none have as many features as Gravity Forms. This plugin literally has hundreds of add-on plugins that expand on its features and integrate into CRM (Customer Relationship Management) systems such as InfusionSoft, SalesForce, and Highrise.

Although Gravity Forms is not a free plugin, you can have it on your website for as low as $39 with 1 year of support and updates. Most Gravity Forms add-ons tend to be free so you shouldn’t need to spend more than that.

8. Digg Digg

If you’re not taking advantage of social media for your business yet, it is time to start. The Digg Digg plugin adds a floating box on your website that enables your users to quickly and easily share the page they are on.

It supports all popular social media websites such as Facebook, Twitter, LinkedIn, Google Plus, and Pinterest. You can customize which services you want to show to your users so that you don’t have to use social media services that are irrelevant for your business or niche.

9. W3 Total Cache

Website caching necessity varies based on your website. Websites that are heavy in images and scripts will see a nice speed improvement from using cache plugins.

W3 Total Cache is a free WordPress plugin that has all the caching features you will need. In fact, they can be a bit overwhelming at first, so it would behoove you to just start slow and test each feature carefully.

10. 404 Redirected

From my experience, business owners don’t monitor their broken links nearly as much as they should. Broken pages present a business and SEO problem for your website. On one hand, your potential customers might leave your website immediately when they see a 404 error, and on the other hand, Google will not pass PageRank to your 404 page.

404 Redirected plugin shows all URLs which return 404 errors and allow you to 301 redirect those to actual pages on your website. This will redirect traffic to the appropriate content as well as pass PageRank to the correct pages.

15 very useful PHP code snippets for PHP developers

Following are list of 15 most useful PHP code snippets that a PHP developer will need at any point in his career. Few of the snippets are shared from my projects and few are taken from useful php websites from internet. You may also want to comment on any of the code or also you can share your code snippet through comment section if you think it may be useful for others.
1. Send Mail using mail function in PHP

<?php
$to = "youremail@gmail.com";
$subject = "my mail";
$body = "Body of your message here you can use HTML too. e.g. <br> <b> Bold </b>";
$headers = "From: Peter\r\n";
$headers .= "Reply-To: info@yoursite.com\r\n";
$headers .= "Return-Path: info@yoursite.com\r\n";
$headers .= "X-Mailer: PHP5\n";
$headers .= 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
mail($to,$subject,$body,$headers);
?>

2. Base64 Encode and Decode String in PHP

<?php
function base64url_encode($plainText) {
$base64 = base64_encode($plainText);

return $base64url;
}

function base64url_decode($plainText) {
$base64url = strtr($plainText, '-_,', '+/=');

<?php
function getRealIPAddr()
{
if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy

$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
?>

4. Seconds to String

This function will return the duration of the given time period in days, hours, minutes and seconds.

function secsToStr($secs) {
if($secs>=86400){$days=floor($secs/86400);$secs=$secs%86400;$r=$days.' day';if($days<>1){$r.='s';}if($secs>0){$r.=', ';}}
if($secs>=3600){$hours=floor($secs/3600);$secs=$secs%3600;$r.=$hours.' hour';if($hours<>1){$r.='s';}if($secs>0){$r.=', ';}}
if($secs>=60){$minutes=floor($secs/60);$secs=$secs%60;$r.=$minutes.' minute';if($minutes<>1){$r.='s';}if($secs>0){$r.=', ';}}
