===== BASIC DOCUMENTATION FOR FILE_FINDER CLASS =====
0.- INTRODUCTION AND EXTENTS
I implemented this class due to a necessity on a website where the users
could upload pictures and those pictures had to be shown and scaled to fit
into general site design...
It handles all operations required to determine wether a pic exists (checks for
different img types if not specified), scales accordingly to aspect ratio to fit
on a fixed space and echoes <img> tag
1.- BASICS OF OPERATION
The class works on 2 basic functions
PUBLIC INTERFACE:
function file_find($imgdir="images") ;
The constructor:
$imgdir-> string with full path to your web img directory (from WEB ROOT DIR)
i.e.:
ROOTDIR = "../" (ROOTDIR IS DETERMINED AUTOMATICALLY BY THE CLASS ALWAYS
RELATIVE TO CURRENT SCRIPT PATH!!)
imgdir = "images" This will mean to get an image you can state "../images"
or "/images" Relative path used on file_find ops
function get_file($fname,$alttext,$maxw=0,$maxh=0,$altimg)
Finds the file and echoes <img>
$fname -> the name of the img file (can have .ext or not... if not stated
cycles through .gif, .jpg, .png in that order)
$alttext -> ALT text for the img tag
$maxw -> Max Width for the pic
$maxh -> Max Height for the pic
$altimg -> Determines substitute for the pic (recursive get_file)
useful for a default img i.e.
2.- Future releases and WIP
I don't think i'll work much on this class, but any new release will be posted
at http://phpclasses.upperdesign.com
Any suggestions are wellcome
