Ok, another thumbnail PHP function. This function support resize of JPEG and GIF, and resize with aspect ratio (set $THUMBX=0 if you wish it is resized with the Height, $THUMBY=0 if blah blah blah, you get the point)

This one may get me in trouble or kicked off MySpace altogether, but I thought it would be a fun bit of CSS magic to post.

As some of you may already know, MySpace does a REALLY good job of preventing images, script and some other tags from being used to customize your space. They have even gone to the extent of using tables without ID's to do the layout.

Pretty ingenious, allowing some customization, but still keeping those annoying ads for single women available to me and my youth groups kids, my family, etc..

Well no more - I want my friends to visit My Site, not just MySpace - so I have a clever method of getting them to go there, instead of posting comments on MySpace...

This snippet allows an aspx page (c#) to accept URL parameters to allow styles or script to be dynamically appended to the rendered page.

I wrote this simple snippet to allow one of our vendors to accept a style override so that their application would morph into something more closely resembling our own portal application. Please see screenshots for clarification.

Give this little function a start date and number of days and it will calculate the end date.

This is a rewrite of a basic ADODB / PHP Database pager. This pager has some very slick search, sort, and display configuration options. Modifications and improvements are very welcome. Thus I am sharing this code.

A basic example for using this pager would be as follows:

// Check class code for CSS styles used
require_once ('class.init.php');

// SQL Statement
$sql = 'SELECT table1.field1, table1.field2, table1.field3 FROM table1';

// Field Labels
$label_arr = array (
'field1' => 'Field 1 Heading',
'field2' => 'Field 2 Heading',
'field3' => 'Field 3 Heading'
);

// Hidden Fields
$vsel_arr = array (
'field3' => 0 // don't display field3 unless requested by the user
);

$sort_arr = array (
'field1' => 'asc' // sort by field1 ascending order (asc) or (desc)
);

// Config array
$config = array (
'db' => &$dbconn, // open ADODB connection
'sql' => $sql, // String of sql
'id' => 'table1_pager', // pager id for session variables
'label_arr' => $label_arr, // field heading array
'vsel_arr' => $vsel_arr, // fields to hide
'extra_param' => '', // extra paramaters to pass with edit, delete, add anchors
'form_width' => '100%', // table with
'form_title' => 'Table 1', // table title
'edit_anchor' => 'Edit', // link to edit
'del_anchor' => 'Del', // link to delete
'add_anchor' => 'Add', // link to add
'print_anchor' => 'Print', // link to print
'header_view' => true, // no function at this time
'search_view' => true, // no function at this time
'pk' => array ('field1' => true), // primary key field
'sort_arr' => $sort_arr, // sort field array
);

// create object then render it ...
$_pager = new pager($config); // create instance
echo $_pager->render(25); // render output

Function that splits a given string into sections based on the allowed length for a section. Does not split words up. Splits string on Space character (can be set to another character)

This function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.

Simple upload class with features such as

- Upload of multiple files at the same time.
- Filtering uploads by size and extension.
- Uploads to configurable subdirs based on date.
- Automatic file renaming if a file with the same name exists.
- Transloading. Copying files from a different host to the local host. (Like Imageshack does)
- And more...

This class is a simple authentication scheme which makes it easy to add authentication to any page by including one class and adding one table to your MySQL database.

The following functions are employed by this authentication class:

auth()

this is the default constructor; it automatically checks for the POST vars "username" and "password", it also checks to see if the user passed the GET variable "logout", which would prompt it to set the authentication status to un-authenticated.

is_authorized()

Checks the SESSION variable "authorized" and returns true or false depending on that variable.

mysql_bind()

This is automatically called by the constructor each time the class is instantiated and $_POST['username'] and $_POST['password'] are present. It queries the db for a valid username and MD5 encoded password.

user_create($username,$email,$password)

Creates a user, if the username is available, and creates an MD5 hash based on username, password and date, to be used in the "activation" of the account.

user_activation_message($username)

Sends the custom activation message to the email address for the username specified

user_activation($activation_hash)

Checks to see if the activation hash is valid, if it is, the activation_hash variable is set to NULL, thus signifying that the account is active.

user_password_change($username,$password_old,$password_new)

Quick and easy way to change the user's password with one function call.

user_logout()

Sets the authorization status in $_SESSION['authorized'] to FALSE

is_username_available( $username )

Returns TRUE or FALSE depending on whether or not the username is free.

This function will set the style of an element by it's ID
