How to do: blah.php?page=blah

[Russia]

How do I do it so like I have a navigation bar with links.

 

Like one link is like

blah.php?page=about

for the about page, and it loads

 

blah.php?p=about

with the about html

 

blah.php?p=index

with the homepage html

 

I dont know whats it called I think its called like dynamic php.

Those links should help

Nope none of them do.

No, those are exactly what you want. The second one deals with the ?p=blah, the third one helps you to load blah.html and the first one is an alternative method

You should note, however, that having an open include like that is EXTREMELY unsafe.  Let's say you want someone to put in:

 

blah.php?page=about.html

 

And you have a file called config.php in the same directory, a person could put in:

 

blah.php?page=config.php

 

And get all the information from that page.  Make sure you sanitize your inputs.

I personally would use an array of allowed inputs and use an if(is_inarray($_GET['p']))

[HaLo2FrEeEk]

Exactly, or if you want to allow the person to access only, say, html files in the same directory, you can read the directory for files, then use a foreach loop to add all pages with an html extension to an array, and there's your dynamically generated allow array.

easy, use

 

 

$_GET['lol'];

 

then

 

&lol=bla bla
