codeigniter upload “The filetype you are attempting to upload is not allowed”

admin — Wed, 14 Apr 2010 02:36:45 +0000

Error when uploading your file using codeigniter upload
“The filetype you are attempting to upload is not allowed”

Causes:

1. Invalid file type uploaded by the user your uploading (.doc when only .xls is allowed)
2. The file uploaded is not within the specified file types added in the upload config
3. Mime type error in codeigniter caused by the mime type of the extension does not match the mime type specified in /application/config/mimes.php

Start by checking what is the mime type of the file your uploading

$data = array('upload_data' => $this->upload->data());
$mimetype= $data['upload_data']['file_type'];
echo $mimetype;

then check in the mimes.php if that mime type matches the extension you want to upload

Example:
word document

'doc'	=>	'application/msword'

excel file has many mime types, if its missing just add it in the array

'xls'	=>	array('application/excel', 'application/vnd.ms-excel','application/x-msexcel')

Images on a MediaWiki wiki will by default, link to the description page
Here is a work around that when you click an image it will link to an ariticle

[[Image:Wiki.png|50px|link=MediaWiki]]

Note: The code above will work in mediawiki version 1.14 and above only
——————————————————————————————————-
Here is the workaround for older versions
Edit the Common.css

.imagelink_somename a {
  width:100px;
  height:100px;
  display:block;
  text-decoration:none;
  background-image: url("http://fullurltoimage")
}

In your wiki code:

mt_rand

admin — Mon, 25 Jan 2010 11:25:34 +0000

The mt_rand() function is a drop-in replacement for rand().
It uses a random number generator with known characteristics using the Mersenne Twister from the php docs website

I somehow noticed php rand() has a pattern, So I dug up the php docs for a better rand function and end up discovering this neat random function

Use mt_rand()

Output

1604716014
1478613278

use Simple_html_dom php library with codeigniter

admin — Fri, 22 Jan 2010 09:37:29 +0000

I was able to figure out how to run Simple_html_dom php library on codeigniter

Download the simple html dom library here simple html dom

I copied the file Simple_html_dom.php to

/system/libraries

Then in my controller I call it using

require_once(‘Simple_html_dom.php’);

To use it, I initialized it using this line

$html = new Simple_html_dom();

Load a page or link using the line

$html->load_file(‘http://www.google.com’);

and parse or find elements using this line

$html->find(‘table tr td’)->plaintext;

works fine and fits right to what I needed to do.

Visit google today and see an animated logo of a falling apple

Newton himself often told the story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree.
Cartoons have gone further to suggest the apple actually hit Newton’s head.

GRAVITY……… and there goes the apple
