<?php
//
// View Source -> Edit Page -> Preview -> Save Page ... All online!!!!
// file that opens a HTML/PHP file for editing and view preview of Web pages
// right now only supports editing of HTML files over http
// To edit and preview PHP files, Wedit has to be in the server where PHP files are persent
//
//1. System requirements
//2. Installation
//
//1. System Requirements
// Any system which has PHP and a Web server installed.
// ftp server on the system from where the page is opened and has to be uploaded.
// Test Broweres - IE, Mozilla
//
//2. Installation
// i) Untar Wedit.tar.gz
// ii) Copy Wedit directory into /var/www/html (DocumentRoot directory of the Web Server).
// iii) File thats opened should have 777 permission
// iv) set "magic_quotes_gpc = off;" in php.ini and restart Web server
//
//Open the page http://Wedit-server/Wedit/Wedit.php and start working
// Readme file
//Wedit is a Web based HTML page editor. Html files over a http server or on the machine where Wedit is installed can be edited.
//
//Http page : html page on a http server can be accessed by entering the http://servername/path/filename.html
//
//Local page: The documentroot is assumed as /var/www/html. So any files (tested for PHP/html file) inside /var/www/html on the server where Wedit is installed can be opened, Edited, Previewd and Saved.
//
//Save page : For Saving page thats on a HTTP server, user's Login and password has to be provided. Wedit saves files on HTTP servers using ftp (file transfer protocol)
//
//Preview page : HTML/PHP page can be viewed by just the click of a button. To preview a PHP page after making changes, first save the file and then Preview.
// CONDITIONS
// file thats opened should have 777 permission
// set "magic_quotes_gpc = off;" in php.ini and restart Web server
// only files over HTTP can be edited
// To edit files over HTTPS, Wedit must be installed on the server only
// PHP files can be previewed only after saving
// All local files are opened using relative path
// Assumes DocumentRoot as /var/www/html
// Does not support HTTPS
$documentroot = "/var/www/html";
