1. Enable mod_rewrite in Apache
   sudo a2enmod rewrite
2. Edit the configuration file.
   1. sudo gedit /etc/apache2/sites-available/default
   2. line 12 says “AllowOverride none” ;
   3. change it to “AllowOverride all”
   4. save and close
3. Okay… one last step — you have to manually restart Apache (or restart your computer!)

sudo apache2 -k restart

All done! now Apache and php can create URL’s on the fly – pretty neato!

My idea is that your [my] local computer retains the POST encoded url for at least one resubmit (When you see a popup that says, “This page contains post data, do you wish to resubmit…”). That opportunity could be used to implement a tool to dump the data somewhere else for future reference.. more to come!

Tonight’s post will be several snippets:

I believe I figured out the error with Xubuntu and Xarchiver – Xarchiver complained that several archives I was trying to open were invalid, even though they were .tar.gz. After fooling around with it for awhile, I tried:

# file [downloaded_file].tar.gz

HTML text document

ah HAH! the return called it a text document – the provider delivered it erroneously! After this discovery, I went looking for a valid copy of the geshi syntax highlighter for PHP in WordPress. The DEV project had what appeared to be the most reliable version -we’ll see at the completion of my post!

On a TOTALLY unrelated note, I saw a story on DIGG today about the Wizpy.. I don’t know much about it, but I have to have one.

(I forgot to enable geshi from the backend.. so I still don’t know if it works!)

Anyway – writing that gave me the idea to write a Apache2 include for tracking visitors – i LOVE the $_SERVER['HTTP_REFERER'] element, and I will have fun just toying with it. Here’s a short explanation how I did it:

First, set up a database and table, then add a user on MySql:

# mysql -u root
# create database login;
# create user login identified by ‘password’;
# grant insert on login.* to login;

This user will only be able to add data to the database, and because he hasn’t been granted “select” privileges, he won’t [easily] be able to see what he inserted.

Now set up the table using MySQL. You can do this from the root account if you choose:

CREATE TABLE `login` (
`count` int(11) NOT NULL auto_increment,
`username` varchar(64) default NULL,
`password` varchar(64) default NULL,
`IP` varchar(20) default NULL,
`refer` varchar(256) default NULL,
PRIMARY KEY (`count`));

The fields are “count” it’s just a simple primary key, “username” will take the value the user passes , “password” takes the password they passed – if this were a real password form that would be an encrypted value – but this is just a toy to see what values people will attempt to pass to a login that they don’t own. “IP” will take the $_SERVER['REMOTE_ADDR'] element, and “refer” takes the $_SERVER['HTTP_REFERER'] element.
Finally, you’ll write a form and a simple PHP page to take some variables and insert them into the database – here’s what I used:

##Add your css here if you want
title> /title> \ form method=”post” action=”?php echo $_SERVER['PHP_SELF']; ?>”> label for=”username”>Username
input type=”text” id=”username” name=”username” />
label for=”password”>Password
input type=”password” id=”password” name=”password” />
input type=”submit” value=”log in” name=”submit” />
$username = $_POST['username'];
$password = $_POST['password'];
$IP = $_SERVER['REMOTE_ADDR'];
$refer = $_SERVER['HTTP_REFERER'];

if($db = @mysqli_connect(‘localhost’, ‘USERNAME’, ‘PASSWORD’)) {
mysqli_select_db($db, ‘login’);
$query= “insert into login (username, password, IP, refer) values (‘$username’, ‘$password’, ‘$IP’, ‘$refer’)”;
mysqli_query($db, $query);
mysqli_close($db);
}else{
echo “The db could not connect.”;}

if(isset($password)){
echo ‘Your credentials failed.’;
};
?

That is really just gross. No kidding. It’s awful – I just started using wordpress and I have discovered that I’ll have to work on an effective way to share code, or at least learn how WordPress handles it. I do apolgize for the ugliness – hopefully it conveys the big picture!
I have a confession. I suck at HTML formatting. I think it’s a failure to learn rather than a failure of creativity. At very point i am struggling with the layout of two tables on www.sl7pm.com that don’t even need to exist. I think I’m going to cruise over to amazon and pick up a good book on web2.0 formatting. My logical brain tells me that means using more CSS and XML, but my creative brain tells me it means making things look attractive.. and I know from my own experience that ugly sites aren’t sticky!

I am still using the 1999 “tables” style of formatting.. which i think is awesome for displaying database results, but needs to go out the door for attractive and functional web design.
The title? I spent a good 5 minutes mis-spelling referer before i realized what a goober i was. I thought i’d add that as a beacon to those who are still mispelling it!
