Update or Delete Multiple Rows using PHP

This tutorial teaches you how to implement a simple update or delete multiple rows or user details in or from the database using PHP.

To select or identify multiple rows of user details, we have used check boxes and passed the ID of each user which were brought from the database to the check box assigned to each user in a html form.

To submit the selected check boxes which holds the ID of each user detail for an update or deletion purpose, javascript is used for redirection to the pages with the scripts that performs the actions needed for each operation.

Password Strength Checker using Jquery

Many websites that require login credentials enforce a security technique often referred to as password complexity requirements. These requirements ensure that user passwords are sufficiently strong and cannot be easily broken.

The passwords are always the most commonly used authentication mechanism. Even as many websites move to multi-step authentication, passwords mode of authentication still pay a key role in securing an account.

A strong password is critical to account security and this tutorial teaches you how to design a system that gauges password strength using jQuery.

Now, what constitutes a strong password? 

Well, that depends on who you ask. However, traditional factors that contribute to a password's strength include the length of the password, the complexity of the password, and unpredictability of the password. 

To ensure password strength, many sites require user passwords to be alphanumeric in addition to being a certain length.

In this tutorial, we will construct a form that gives the user live feedback as to whether their password has sufficiently met the complexity requirements we have established.

The user also will be able to click on a check box to see their real password to avoid mistake when typing their desired passwords.

The purpose of this tutorial is to show how a simple script can be written using jQuery to enforce password complexity requirements. You will be able to add additional requirements to the script if needed.

There is a README.txt file in the downloaded folder that gives you information on how to add additional fields or requirements if needed.

Visitor Tracking System

Web Tracker / Site Tracker / Visitor Tracker

What exactly is a web tracker (also known as a visitor tracker or site tracker), and why do you need one?

The idea behind a web tracker is very simple and has been around for many years. Essentially you place a small piece of code on your website, when someone visits your website, that small piece of code is executed and the visitor's public details (ip address, browser, operating system, referrer, page title and url etc) are analysed and stored for reporting to you later.

The great advantage of web trackers are that they are better at tracking 'real people' as they track browsers NOT server requests. This often means a web tracker will have a significantly lower count than standard log file analysis. But it offers a more realistic figure of the visitors to your website and far more detail.

Some important benefits of the system!

The system will help you to know the number of visitors that visits your website daily, weekly, monthly, and yearly. This will help you to know where your real customers are located or coming from so as to follow them appropriately. It will tell you the operating systems, web browsers and screen resolution of the computers that your visitors use to access your website. It will tell you the countries and cities of the visitors that visits your website. It will tell you the number of visitors that are viewing your website at a certain time. It will tell you the search engines used to find your website. It will tell you the pages viewed on your website and the search engines where the visitor came from to your website page. Above all, your use of the application is free and no special sign up is required, you only need to supply your website home page URL to get a small piece of code that you can place at the BODY section of your webpage for visitors tracking purpose. The application is also responsive to screen. There are options where you can change the width, visibility of the tracking system and other important settings in the tracking code generated.

Send Mail with File Attachment via SMTP using PHP and Jquery

We have come to realise that most of the emails sent via the PHP mail() function are often treated as Spam and sent to the Spam Box instead of the Inbox because the PHP mail() function does not use a well configured SMTP Server.

We have designed a system that can be used as a Contact Form and be placed at the contact page of any website or be used as a Mail System for any website.

The goal of this tutorial is to introduce a secure means through which you can easily send emails with File Attachment via SMTP using PHP and Jquery without the need to log into your email accounts.

Imagine a situation where you send an email to your users/clients or these users/clients happen to contact you via your website and the messages sent are treated as Spam instead of a genuine message, moreover, it is not all users that bother to check their spam box.

This application brings an end to this kind of situation as illustrated above. This application now gives you the hope that all genuine messages sent or received will go straight to the Inbox where they were sent and no longer the Spam box.

You have received this email in your Box because it was sent with this new Mailing System which is located at the below URL.

Responsive Menu using CSS and jQuery

This tutorial teaches you how to design a responsive navigation or menu using CSS and jQuery.

Responsive design has basically become a staple to any modern website. Having this in mind, navigation must be ready to adjust to the various screen sizes possible. As you'd imagine, a 10 item long horizontal menu doesn't translate well to a cellphone' screen. However, with a bit of proper tweaking, we can make a proper responsive menu for use on mobile or small screen size.

Convert text via Google to voice using Jquery and PHP

This tutorial teaches you how to convert Text To Speech via Google API using Jquery and PHP.

The system sends a HTTP GET request to Google Speech URL that does the conversion of text to an MP3 audio file as an out put.

Below is a sample URL through which the request to Google is made.
