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)

I found this to be a neat little trick for hiding(somewhat) source javacscript code from peering eyes...

This function will unload all linked javascript files so that when you view source - you see no javascript files! (Especially helpful when using FF and using web-developer tools - no linked js files are displayed) The files remain resident in memory - allowing for the functions to work.

Just call the function in the tag

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.

Just confirms if the user really wants to save the page or just hit the Ctrl+S accidentally. Works in FF maybe in IE too.

This creates a black screen if the browser is inactive for a certain amout of time. I am not sure if it works in IE too but works fine in Firefox.

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 is a brief revision to my previous snippet. It is still what it was: a small, simple system for using XMLHttpRequest without using globals.

I'll put the API spec in the code this time, so as not to clutter the front page further.

Changes:

Changed name to HTTPRequest (far more accurate)
Added HEAD requests
Shortened code by making a GenericRequest function
Used a better method for getting an XMLHttpRequest object (checks multiple MS versions and implements the latest one)

This is a simple script to provide basic cross-platform XML request functionality in Javascript. It's meant to be the core component in any AJAX style framework. It is not an instantiable object, but instead is a namespaced microlibrary.

Calling is easy:
XMLRequest.GET(uri, query, callback, fallback)
uri: The location you're after
query: an associative array of form data to provide via the URL
callback: callback function of the form myCallbackFunction(objXMLHttpRequest), which is called upon successful (response = 200 OK) retrieval of the XML data
fallback: myFallbackFunction(objXMLHttpRequest), which is called upon failed (response != 200 OK) retrieval of the XML data.

XMLRequest.POST(uri, query, form, callback, fallback)
Similar, but does the query using the POST method. 'query' is the URL-appended data, still in associative array form, and 'form' is the same for the POST data.

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.
