Hello, this is Rob cabin. Thank you so much for watching the course. Thank you for investing your time with me. Now first thing I want to say even though WordPress is a secure and mature software, it's been around for 13 years and as you know, supported by a huge community, it is the target of hackers because all content management systems are. So couple of pieces of security advice going forward. First of all, remember your username and password for the WordPress back end.
And for the database is extremely sensitive information. Change it regularly, and do not share it with anyone. If you create a new user for a freelancer who's doing some work on your site. Do remember to delete that user once they've finished. So change your passwords regularly. Keep Secret and keep them hard to make up next piece of advice is very important and that's to always keep updating WordPress and the themes and plugins.
WordPress itself is updated many times through the year four major updates and other smaller updates. All the plugins and themes might need to be updated to run with the new version of WordPress and it's very important that you do these updates as soon as they are available. WordPress may update itself automatically but none of the themes and the plugins do. So you really need to keep an eye on the WordPress back end to see if anything needs updating. Then if it needs updating, you should copy the site's the files and the database and then do the update. Because that will keep your WordPress install secure.
Okay, so another point I want to make to you is that I don't want to give you the impression that WordPress is just a drag and drop user friendly interface for people who don't understand code and markup that couldn't be further from the truth. With knowledge of HTML, you can use that and put that into WordPress pages, you can put it into text widgets, so you can put your knowledge of HTML to good use in WordPress. If you have knowledge of CSS very important. Of course, you can use that in the theme you're using. An important point to make here is that you should use a child theme on a theme framework or a theme that is being updated regularly. I use Genesis theme which is a premium theme used by millions of websites, and extremely well supported by a huge company.
They sell their framework for $60. And I create a child theme on that. Now when you've created a child theme on a theme framework that's regularly updated it almost future proofs your installation. And you can use your CSS knowledge in that child thing. Even better with knowledge of PHP, and MySQL, you can create plugins and themes for yourself. You can also use PHP in the back end.
So here are a couple small examples of how you can use PHP and WordPress with the help of a couple of plugins. So here I have widget logic activated, which means you can add WordPress is conditional tags to widgets. So here I have some PHP in this widget, saying that it can display on certain pages, but not on others. And another plug in this time exec PHP This allows you to execute any sort of PHP code in posts pages or text widgets. And here I have it in a header widget displaying information depending on whether somebody is logged in or not. And in addition, missing people if they are logged in by their first name.
So as WordPress powers over 25% of the world's websites, knowledge of WordPress, and maybe HTML, CSS, PHP and MySQL databases, and JavaScript, give you a huge benefit in today's online business, you'll be able to help many people out there who have websites and you'll be able to create new websites for over four figures. I hope you've enjoyed these set of videos, and I hope you can see ways where WordPress can help your business or how you could use WordPress to set up a new business. My name is Rob coven. I'll see you in the next video.
