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)

Gives you the ability to dynamically include a CSS file at any time in your HTML page using Javascript.

a simple css way to add shadow to tables and Divs

Create a Thumbnail

This is a simple function to generate a random ID of letters and numbers however long you want. All you do is pass it how many parts you want and then how many pieces(chars/numbers) per part you want.

I hope you enjoy

The basic framework of an Ajax-enabled web page. The following JavaScript shows how to send a request for an XML file and how to receive that request. Of course, in a real life scenario, you'll have to implement better error trapping and actually do something with the XML that gets returned.

This is a PHP and JavaScript Image gallery that I created. There are 2 uses for this.
1.) You can save it as index.php and place in a folder containing images and it will display the images in that folder.
Example:
place index.php in images/folder
http://yoursite.com/images/folder/
This will display all images in that folder

2.) Pass in the path to the folder to display in the url
Example:
Save as imagegallery.php
http://yoursite.com/imagegallery.php?path=images/folde

Get the Size of a Folde

This snippet originally is used for targetting ads banners depended on the geographic location of the visitor, but can be used for other purposes. Also originally is used for US and the rest of the world, but you can add check for other countries too.

"Today in the news, MySQL previews..."

As a "preview" of text, this MySQL select will return the first few words out of a text field in a database. It returns entire words (doesn't cut them off in the middle) and follows the last word with an elipse "..."

In the PHP, assign $CharactersToDisplay to a number - the approximate number of characters desired (or you can hard-code it if you want).

For the example, I also use $TheID as the row identity for the record to display.

Get computed Width of an HTML Element

Proper Paragraphs

A quick and simple function to dump a variable (array, object, string, int, etc) out into -formatted output for a web browser.

If the variable is an array or an object, you can have it returned into the another variable for later processing (i.e., through templates or e-mail). Due to lack of free time, if the variable is not an array or an object, it will ignore the $return value and print directly to output.

Future revisions will add the above mentioned functionality.

If you've ever wanted to build an application that can both find the distance between two zip codes, and find zip codes within a specific radius of another zip code, then this is the snippet for you.

I've tried to build this before using PHP4 and MySQL 4 and have found it to be painfully slow for a one-user connection over a Local Area Network (LAN). So, before you continue reading, I must make it abundantly clear that this method requires PHP 5 and MySQL 5.

This is because in PHP5, we will need the MySQL-Improved interfaces, and in MySQL 5, we will need functions and procedures.

Using functions and procedures in MySQL puts the weight of the calculations on MySQL, where they will run hundreds of times faster than if PHP were to attempt to do the work. In addition, using functions and procedures is still hundreds of times faster than carefully crafted SQL statements (one benchmark took over 10 seconds using a WHERE clause, while the function + procedure method took around .12 seconds--note the dot).

Since I am not a mathematician by trade, I found the necessary calculations using Google.

For the "Great Circle Distance" formula, I used Meridian Word Data's website. For the radius finder, I used another that unfortunately I do not have off the top of my head right now. I will look for it again and repost it for proper accreditation.

For the zip code database, I am using the free zip code database from CFDynamics.

Below, you will find the database and table schema, the functions and procedures, and also a demo PHP script to see all of this put into action. As a courtesy, you may download a dump of this database from my website. It's uncompressed size is 3.4M, and it's compressed size is 537K. The checksum is available here.

Please leave me comments, suggestions, questions, and/or rants about this snippet. I feel this is a very useful bit of code, and hope that others out there may find as much use from it as I will be.

To debug javascript code we use alert() whereever needed and it irritates you while alerts values inside a loop and other places where more alerts are being shown and you have to press the ok button to pass / proceed on.
here is a simple way to get rid of the alerts dialogs and get the values outputed into another debug window.

This function creates relatively secure random passwords. It's by no means ideal, but it should work in most non-critical situations. The nice thing is the generator attempts to create passwords that people can pronounce and chooses letters that won't be mistaken for others (such as the numeral "1", an upper-case "i" and a lower-case "L"). To keep the code short much of this functionality is very rudimentary, but it's better than nothing.

This snippet will undo all the nasty stuff which happens when you set register_globals to on in your php.ini file.

(Originally found in the code of Wordpress).

Add dragging to your div elements. just adding class="drag" to the div element will make it draggable.

Here i'm adding an example for a draggable dialog box

This function makes URLs in a given text clickable, and shorts down the link text if it's length is over the specified one. (Like vBulletin, etc... does)

Get Gravatar Image

The recursive function stripslashesDeep($value) will (upon called) strip slashes (\) from strings and arrays (even arrays with arrays within themself). The controlstatement (if) checks if magic quotes gpc is on, if it is we strip the slashes it have added.

Very good snippet if you want to have the "same" input even if you switch to an enviroment where magic quotes gpc is set to something else than on your originall server.

Database Class with quick connectivity and useful database functio

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)

Format a phone number with php.

A small function to help you debug your PHP scripts (with the debug modell, output as much as possible to see where the script fails).

A simple AJAX class. The code for the class is provided as well as example HTML and PHP code for usage.

I've seen XML 2 Array functions done in other ways but this is the shortest implementation I've seen yet. I didnt write it myself though, but I thought I'd submit it for common good of this site. It uses regex and works prefectly.

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 litle snippet shows how to store passwords and then check inputed passwords if they are correct.

(In this snippet we use som pseduo code for the database connection).

List all plugins installed in FF

Not really a hack, but rather a workaround for layout problems with IE.
Conditional

Get computed Height of an HTML Element

A small recursive php function to determine the size of a directory by adding all it's contents together and returning them as an integer.

Generates a tree view within a dropdown select box.

Basic internal class loading for PHP. Could make some plugins with this code if used properly.

This is a bare-bones DB connectivity class. It's really just meant to abstract a few basic mysql_ functions so that if you ever have to change DBs you don't have to change every database function call.

I really just threw this together on a whim with no testing what-so-ever. Also, it only abstracts the most basic MySQL functions--this is intentional; please expand it as you see fit.

This function converts a CSV file to a simple XML file.

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.

Get File Extensio

Strip HTML

This function calculates how many lines will text occupy.
Example (simple):


$string = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Phasellus tincidunt posuere dolor";

$num_lines = how_many_lines(10, $string);

It accepts a third, optional, parameter $options, that allows you to change behaviour. $options should be array. Following configuration options are available:

'white_spaces' - default: array(' ', "\t") - array of chars, that should be treated as whitespace.

'new_lines' - default: array("\r\n", "\n") - array of strings, that should be treated as newlines. For example, for HTML you can set 'new_lines' => array('');

'force_line_breaks' - default: true - force wrapping, when the token is longer than width, or not. If set to false, and token cannot be fitted into $width, function will return false;

'callback' - default: null - callback function for determining character width. Must accept at least one parameter - $char

'callback_params' - default: array() - optional additional callback parameters

'char_widths' - default: null - associative array in a form $char => $width, which contains char width. If $char is not found in the array, it's width is defaulted to 0.

Here's a library to manage CSS class names on DOM elements.

Set a word or phrase in an input field, clear it onfocus

Here's a basic function for debugging any kind of PHP variable. It allows for "invisible" or "visible" output--that is output in HTML comments or within visible HTML tags. It also supports customizable "containers" which lets you easily edit the look of the visible and invisible blocks. Examples in code below.

MySQL 5.x Stored Routines, PHP Session Values, a little CSS oh my! Complex to set up but easy to impliment. Geared toward security, simplicity (of use) and convenience.

This is a random password generator that produces understandable passwords based on word lists. I've only included a 3 entry world list because you should chose a list based on your password requirements and your users. If you need to generate passwords that are 14 characters in length, you will want a different list than if you're generating 8 character passwords. And depending on your users, you may want to use certain lists. The list I use is about 4000 words that are 5-7 characters long, all well-known words that have had potentially objectionable content removed. For security reasons I don't want to include this list.

A note on security: though this generates relatively strong passwords for the average user, they are particularly susceptible to brute-force attacks. This is even more an issue if somehow your word list gets compromised. I would not recommend using this function for anything where a highly secure password is needed.

A note on choosing your list: You'll also see that I've built the system to avoid generating passwords with zeros and ones in them. This is because zero and upper-case "o" can be confused as can one, lower-case "L" and upper-case "i." When choosing my word list I was also sure to strip out all words that start with the letter "o" or "i" (to prevent the optional ucfirst() from creating 0/O and I/1 confusion) and words that contain the letter "L" (to prevent l/1 confusion). I find that this greatly helps with preventing confusion, but again weakens the security of the passwords some. It's your choice.

Flexible sorting algorithm based on Quicksort with extra functionality, such as:
- Direction (ie: ascending or descending)
- Sort-by-path (eg: item.name, item.name.firstName or item[5])
- Sorting function (returns true if two items are already sorted)
- Type checking
- All constants and support functions are members of the Sort() function
- Testsuite with hooks for cscript and in-browser javascript, so you can tweak and optimize, and make sure it still works
- Environment agnostic (can use with, say, SpiderMonkey or .Net's jsc)

I needed to send an email through an authenticated SMTP server. I found the snippet on the PHP website to do the trick.

Generate a random number or string in PHP.

Using styles we can add scrollbars for large table where the space is a constraint

This snippet effectively reads an XML document using XPathDocument (read-only) instead of using the DOM. This snippet returns the full element values in between elements. For example:

root element
code element
This is a test.
/code element
/root element

GetXmlString("/root/code"); //returns 'This is a test.'

For those times you need to do a loop in PHP, but have the outcome be in descending order (ie, start at 10 and end at 1).

This little function will split an e-mail address passed to it at the @ sign, and make sure that there is a valid e-mail server at the other end =)

Trim , Left trim (ltrim) and Right Trim (rtrim) in javascript

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.

If you're an IE user you may have noticed that when you hover on a medium to large sized image, a toolbar appears in the corner of the image. It's basically useless as it accomplishes nothing that can't be done with a right-click.

Luckily, Microsoft has included a way for webmasters to disable this function.
