Tumblr Tip: Editing those 404 pages

One of the worst things with Tumblr is that you can’t edit those 404 pages… But with some simple jQuery, now you can!

Code:

$(document).ready(function() {

$("p:contains(The URL you requested could not be found.)").append(".");

});

What it does:

When the page loads, it checks to see if the Tumblr 404 text is there in the paragraph. If it it, it adds to it. If not, nothing happens. Its that simple.

Creating a file and downloading it in php

Today I’ll show you how to get a user’s ip, stick it in a text file, and have the download it all without the text file being stored on your server for more than a few seconds.

Step 1: Getting the I.P Address

To get the ip address, we use this code: $_SERVER['REMOTE_ADDR'];

So when we put it as a varible:

$ip = $_SERVER['REMOTE_ADDR'];

Step 2: Creating the file

Now that we have the user’s ip address stored in a varible, we want to put it in a file.

So first, we need to create the file:  fopen($ip, 'w') or die("die");

If you notice, we are using hte person’s ip address for the file name.

Now here is the final piece of that code: $file = fopen($ip, 'w') or die("die");

Step 3: Writing to the file

So we have the file created and now we need to write to it. Use this code to do so: fwrite($file, $ip);

Note that it writing the ip address to our file

Step 4: Close it

Not much for this: fclose($file);

Step 5: Forcing it

Now that we have the file created and with the ip adress in it, we have to make the browser be “forced” into downloading it

$filepath = "/home/manywor/public_html/phptest/";

$file = $filepath . $ip; header("Content-type: application/force-download");

header("Content-Transfer-Encoding: Binary"); header("Content-length: ".filesize($file));

header("Content-disposition: attachment;filename=\"".basename($file)."\""); readfile($file);

I’ll explain all that in a later tutiral.

Step 6: Deleting the file

To delete the file, all we need to do is this: unlink($ip);

Note that it deletes the file named after that ip adress

Final Code

//Get the IP Address of the user

$ip = $_SERVER['REMOTE_ADDR'];

//Create and close the text file

$file = fopen($ip, 'w') or die("die");

//Write to the text file

fwrite($file, $string);

//Close it fclose($file);

//Force it

$filepath = "/home/manywor/public_html/phptest/";

$file = $filepath . $ip; header("Content-type: application/force-download");

header("Content-Transfer-Encoding: Binary");

header("Content-length: ".filesize($file)); header("Content-disposition: attachment; filename=\"".basename($file)."\""); readfile($file);

//Delete it

unlink($ip);

Final Thoughts

To make the file download as a text file, you’ll need to stick an txt extension on the ip adress. I used this code to do so:

//Replace the dots in it

$ip =str_replace(".","",$ip);

//Turn the IP into a text extention

$extiontion = ".txt";

$ip = $ip .''. $extiontion;

Also, its not secure, so I would clean it up before using it ;)
