See the section titled What can PHP do for more information. PHP-enabled web pages are treated just like regular HTML pages and you can create and edit. Laravel is a powerful MVC PHP framework, designed for developers who need a simple This tutorial is particularly meant for all those developers who have. This class is intended to give you a feel for how PHP and MySQL interact together, and to show the basics of a CMS. I'll be skipping.

In this case, we're going to check the entry to make sure that data was returned, then remove the slashes that were added when we saved the information to the database using stripslashes.

After that, we simply wrap the variables in some HTML and, voila!

As a final step, the code adds a link to the bottom that allows users to add an entry. It's worth noting the use of the ". So, you've now written your first CMS class!

You can easily write and retrieve data to and from a database. All that's left to do is to try it out! To use our class, we need to create a separate file.

I'm going to call it "display. To start, we just set up a document with plain ol' HTML. Then, we have to instantiate our object so that our code knows what's going on. Third, we set all of those variables we talked about toward the beginning of this tutorial. You'll have to replace all of those values with the information you get from your own server or hosting company.

And fourth, we connect to our database using the connect method. This is because we're using the same file for input, processing, and display of information. Then, we use some shorthand trickery to run a conditional statement. And that's it! Once you get a feel for it, this sort of basic programming will allow you to start exercising total control over websites you build, whether you decide to really dig in and build your own CMS framework or just improve an existing CMS by, say, writing a WordPress plugin.

Really, when it comes to modern web design, you should have at least some understanding of how things are working behind the curtain—understanding how a site works will better enable you to design sites that have a more fluid integration of form and function.

This code is written for demonstration purposes only. Several security holes have been pointed out in the comments, which I have addressed in Part Two of this tutorial series Editor's note: There is no part two of this series anymore. Still, I would strongly advise not using it for production websites without further testing.

I have covered some of the bases with security, but other issues may exist. Further reading on security risks and safe PHP code can be found here. Please read through this before implementing this code on your server to avoid potential security holes.

This is excelent! Thanks again for the quality: Definitely going to follow along with this one and use it as a basic CMS for clients who want brochure sites. A great follow up to this from my point of view would be how to adapt this simple CMS in the same format to support multiple pages. In the process of updating my clients website to make it easier for them to update in office.

This will work perfectly!

Thanks a bunch! Great tutorial! This is a great example of simplicity but yet has advanced concepts behind it. In the future could you maybe expand this to include updating, and deleting? Great work Chris. Thanks for your efforts. Classes only make your code better when used correctly. Just when I wanted to start to learn some PHP. Good way to begin. Thanks for this one, keep on coming with this kind of tutorials. Fur fuck sake, use a framework! This is why PHP applications grow to be unmaintainable monstrocities of vague undocumented code….

This is the best way to improve our work and also is very professional. Also, why would you ever want to learn WHY stuff works. Because you know, the people who write CMS tools and frameworks were just born with CMS tools and frameworks already made.

Thanks Jason Lengstorf, this tutorial was great because it only did the bare minimum and I have read through a few books and they always do tutorials on how to make a CMS, but they are always way drawn out and confusing for a beginner.

A real-world CMS is incredibly complicated, and, like hatesflats said, they can become sprawling nightmares for maintenance. Having a grip on PHP and MySQL and the way a CMS works, however, will give you a great advantage when working with a platform like WordPress, or if you need to create a small site or widget that would benefit from a database.

To everyone else, thanks so much for all the positive feedback! The problem with using a framework or CMS before trying to build your own is that you never learn what to look for in a good framework. Trying to get a handle on the hundreds of PHP packages is a huge task and you can narrow down your choice considerably by getting your hands dirty with your own code. I really like this, can wait to read more, maybe edit and put in some ajax, like small tut which includes everything.

Err you need to fix the demo link…. I get a message box informing me: They were from http: The advantage here is that some very, very smart people smarter than you or I have thought about the hundreds of ways someone can hack your site.

By using a framework, you can take advantage of those great minds. I know this is a very simple example, but you were hacked in a few minutes.

The CMS example is very nice and well written and a great intro to PHP, but if one is to continue on this path they will soon have to deal with session management, sql injection, XSF, session fixation, and on and on. No one is complaining about their bloat. So all you code studs: That being said, if you liked this tutorial, you should check out cakePHP tutorial on how to create a blog and see how it compares to the direct coding method.

This is an example people, set up to have inexperienced programmers learn something. Tutorials like this are really enhancing my learning experience. Thank you to all that contribute. Thanks Chris. This is exactly what I was looking for to build my own CMS. What would really be useful would be showing a way to make categories..

Thanks Chris and Jason for this tut.

Nice tutorial to get me going for a CMS. I am a seasoned ColdFusion developer and took time last week to do the full immersion into php, so I could churn out smaller sites on much cheaper hosting. I do want to make a reusable CMS so i can easily drop it into future sites. It is one thing to keep improving on pre-existing code, but every now and then, starting from scratch is simply the best solution in order to use all of the latest techniques, and this is how you learn.

Hi i like this tutorial alot but i have one question ask. I know that PHP is a scripting language and that Rails is a framework, which language would be the best to learn first in order to understand the other on? Please and thank you.

Create it, and then store somewhere that it is created — or just do so manually. XSS exploitable. This function makes PHP count each and every row manually. The best solution for large datasets is to either to a COUNT query separately or even better, in the while loop, set a flag if any posts were processed or not. Speaking of which, you could just do if! Especially if magicquotes GPC is off, as this will strip legitimate slashes.

Escape it before displaying it. Thanks for pointing out holes in the script. I assure you they were unintentional. I think this article is very well done and will prove to be a great help to many ambitious web heads! I was commissioned to build a custom web app for a client recently Dec. So I spent a week going through a very nice tutorial over at lynda. BUT , I think this article would have saved me a lot of time; had I read it prior to my project.

In the same function you have data access, business logic, and templating logic.

Use with caution. Great post, Jason. Thanks very much! Would be great if you expanded on this — making a more comprehensive CMS? Make sure you grab my RSS feed or follow me on Twitter!

I know JavaScript uses var, but what is the purpose of it here? Turns out that I was using PHP4 syntax. Instead, I should have declared the visibility of the variables i. PHP is a great web programming language — going around running and telling people to use Rails instead will only cause confusion with beginners. Thank you. I am getting an error when running your code on my server:. Undefined index: How will a beginner know that this code blows, and that they should seek more education, unless you tell them?

You incorporate the html inside your html when you should be separating it. You rely on few PHP flaws, ignore notices, instead using everything correctly.

Gives you bad example for being a programmer. Great tutorial. Hey mate. Neat tutorial. The way your server has notices set up is causing those errors. To correct the first, you just need to add a check if the variable is set in display. I guess with the simple code in the tutorial the whole process will be fast, but once you reach complexity levels like WordPress I find the speed is not what I imagined it to be. I did a lot of research on why this was and the bottle-neck was always mysql, not php.

So what about a simple CMS without a database, or one with a lightweight database? PHP part 9: SQLite My Fire! PHP part Bugging Out — Part 1 Basic error handling. The Trashman Cometh — Part 1 A primer in basic security. Version Negotiation Explained.

This is formatted in a way that jQuery can easily loop through each follower and then append them into the list. Loading Followers with Ajax This last bit of code inside ajax. Notice that my selector is targeting the page body and we pass the morefllwrs button as a parameter to the. The purpose is to handle clicks on the same link which gets dynamically appended into the page.

So right when the DOM loads jQuery will target the first link, and a user will click to load more followers, but in order to get another button to appear we need to add HTML onto the page using jQuery.

Click here to try a free trial on Treehouse. By using the whole body as our selector it will keep listening for the click event including new elements which are added to the page after loading.

In fact, the biggest difference will be found inside the success function callback since we are using a type of jQuery. We turn each array object inside the JSON string into a new variable called item. Since this is a very basic example the objects only have two keys — item.

Any real-world example might include many more values.Localization happens when you adapt the interface mainly by translating contents, based on the i18n work done before.

This code is written for demonstration purposes only. It is an amateurish introduction to PHP. Tan Zhenyang. A Database is not a Table. Just my 2c.

A real-world CMS is incredibly complicated, and, like hatesflats said, they can become sprawling nightmares for maintenance. Then, we have to instantiate our object so that our code knows what's going on.
