I've written a tutorial, for two purposes. First purpose, so people can learn how to make a site navigation with php, if they don't know yet. Secondly, so people can tell me how I can improve, or give me some piece of advice. Here's the tut:

Description: In this tutorial we'll learn how to make our site navigation like index.php?page=contact.
Skill: Beginner
Time needed: 15 minutes

As stated before, some experience with html (and php) is required, since we won't be going into too much detail. You can always at any time
ask questions on our forums, send us an e-mail or use the contact form.

Right, we'll start of with the main code:

You should paste this code into your main index file, on the part where you want your content to be displayed. The next thing you should do is edit the id's and the links. On top of the code it says the following:

As you can see, the id 'news' is linked to 'news.html'. You can name any id like you want to call it, and also any link. news.html, news.php, it
all works. Also, files which are located in sub folders can be linked. Watch the 'contact.asp' link. It's located in a folder called 'contact'. Also
this link will work. The id can be changed to whatever you like:

The next thing you would do, is fix all your links in your menu's:

Add the following:

Remember, once you change the 'id' to something else, like 'page', then you will have to update your links aswell:

If you have for example a downloads page, you can add the main code posted above to a file called 'downloads.php'. Change 'id' to 'downloadid'
for example, and you can link like this:

Just play around with it a bit, and I'm sure it will work out for you.

Thats pretty much the same code I use on my site.

Yeah I'm sure many use it, since in my eyes it's one of the easiest codes to use.

just make sure you dont have any secret files cause someone might use

?id=../../secrets/ftppasswords.ext

Well that's not going to work, because you need to specify all the ?id= links into the code, so it wouldn't work.

why don't you do it like


Thats what I use on my website ... a whole lot easier, and every time you add a page you do not need to add a case statement

Yup that's a better code, something I wasn't aware of yet. I'm using it myself now, thank you.

There's a lot of more ways to make such a php navigation. I just made a tutorial about the one I am/was using. Plus in my tutorial you'll learn about includes and the GET function. Slightly more advanced I believe. But the purpose of this tutorial mainly was to see how my tutorial writing skills are. Thanks again anyway

Livemans code but shorter


A quick explanation on what livemans code does to those who dont know:
Basically it checks if the variable id is empty or if a php file exists with that id, if either condition is true it includes news.php else it includes the requested file

I would recommend the case method as its securer

I am working on exactly this sort of thing. So the tut helped me out a bit Thanks.

No problem, I'm glad it helped

I fail to see what is so good about using this?

I dont understand how you get the extra bits like index.php?id=contact&contactmethod=email.

Any help?

There's nothing good about using it. It's just a tutorial, meant to help out people using some PHP variables. It's not a script I made, it's a tutorial, which is designed in the first place to help out people. Anyways, that's all I have to say about it.



Rob_BCFC. It's not the best method, but if you want such links, you should do the following:

On your index file youçe placed the code script. You've defined the id contact. Now, on your contact.php file, you'll also have to define the code. But this time instead of using id, you'll be using contactmethod. Since you work with cases, you'll have to pre-define everything first.

Example:

You index.php file is looking like this:



And your contact.php should then look like the following:



I hope this answers your question.

ye this is a great tut

but isent mod_rewrite better:
its neater and good for SEO

I used this scipt before. But now i found one problem. When trying to include a file that resides in another folder, say:

case "site9": include('webdesign/site9.htm',);

the page falis to show the jpgs. The jpgs reside in the folder webdesign. So does the htm. It´s weird. Can´t figure it out.

When i used it for the first time, all the php and htms lived in the root folder, and there was no problem with those.
But now i´m using these sub-folders...Any help will be greatly appreciated.

you need to specify where all the images are


so if an image is in "contact/images/email.gif"

and you include the page "contact/contact.php"

in the contact.php you will need to specify that the images are located in

"contact/images/*.*"

ie <img src="contact/images/email.gif">



probably confused you... but eh.


my way to do this is much eaier.

and uses less files. like 4 total.
auth.inc.php // for login
functions.php // functions such as "pages"
admin.php // admin control panel
index.php // main file.

I sure am liking the tutorials here. Great advice, thanks

lol i prefer

<?php
if(isset($_GET['fd']) && isset($_GET['page']) && file_exists($_GET['fd']."/".$_GET['page'].".php")){
include ($_GET['fd']."/".$_GET['page'].".php");
}else if(isset($_GET['page']) && file_exists($_GET['page'].".php")){
include ($_GET['page'].".php");
}else if (empty($_GET['page'])){
include("main.php");//main page
}else{
echo "Error, that page does not exist.
";
}
?>

basycally make a folder called test and a file called testing.php
make yoursite.com?fd=test&page=testing
if it appear it worked
and you dont have to add case...blablabla each time u wanna ad a page

fedekiller, what is the advantage of your code and this post above? To me they do the same thing except yours also checks for a folder. Am I right with that understanding?

yes and the other big difference
each time you wanna add a page you ahve to do case(page):include.......
in my code you dont have to make it, just add a new page and call it ad ?page=newpage

You don't need to add a case statement in the post I linked to

Thanks

NP ^-^

I would just go like this

Not sure what you are saying there
Do you know what advantages one has over the other, or does anybody else know?What are the advantages of using this code compared to the others posted?

In this code


This part

Calls the id the first part of that $requestlct = $_GET['id']; gets the file name that you put in the link. The else statment
} else {$requestlct = 'idx'; That is the default file it will get if nothing is specified. To make the idx work you must have a file in the source folder with the name idx.php so the path to your idx file would be "source/idx.php"

This part

Checks to see if the file exist and if it does it sends you to "source/$requestlct.php" where $requestlct.php is the page name. like if your link was index.php?id=news the $requestlct.php would turn into news.php. If the file you specifed doesnt exist you are sent to the 404.php page which is your error page.

Hope that helps. Thats a great way to do the navigation although ALL your files must have the .php extention to work.

Thanks for the explanation mbx5nitro My query however is that code better than the code that was posted earlier in the topic?

Im not sure i dont understand the security aspect enough to say i would say the code i explained is better but i dont know. maybe someone else can say more.

man that tut helped me alote thanks

You would be correct, assuming he was doing something like include $_GET['id'].".php";

which i think is bad coding all together without some sort of checking of the user input. I think I've read it hear before as well as elsewhere, but as you code, you should never trust user input. Even by accident, someone can find a vulnerability.
