Often when designing websites static or dynamic, PHP or ASP.Net, Laravel or WordPress, you have to design in a way that if the user hovers an image it gets changed and an alternate image is displayed. This can be easily achieved via simple HTML events. Here is the trick:
<img src="FIRST IMAGE URL GOES HERE"
onmouseover="this.src='SECOND IMAGE URL GOES HERE'"
onmouseout="this.src='FIRST IMAGE URL GOES HERE - AGAIN'" />
It is simple as that.
Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps. If you want to learn more about Docker head to their What is Docker section here.
CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications. If you want to learn more then head to their official website which has great documentation as well at https://codeigniter.com/
If you’re excited about using Docker for your development and you are working on a CodeIgniter (CI) based PHP project then you are lucky. It is very easy to setup CI based project with Docker. Just follow the instructions below to setup a fresh CI project with Docker.
docker-compose up -d
It will spin up two containers—one for the app itself with Nginx and another for MariaDB for your DB. App container will create a directory in your project folder and install CodeIgniter in it.
Now browse http://localhost:8000 in your browser and you’ll see the CodeIgniter page. It’s that easy.
Using Response.Redirect in a try catch block in C#.Net will throw an exception “Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.”.
To work around use the overloaded method Response.Redirect(String url, bool endResponse) and pass false to second argument. The detailed reason can be found at http://support.microsoft.com/kb/312629/EN-US/.
