file that opens a HTML/PHP file for editing and view preview of Web pages <?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"; printf("<html><title>Wedit -- Edit html and PHP pages in Web Browser</title><body>\n\n"); printf(" <script language=\"javascript\">"); printf("var showdiv = 0;"); printf(""); printf("function previewpage(source,file)"); printf("{"); printf(" var previewdiv = document.getElementById(\"previewdiv\");"); printf(" if ( !showdiv )"); printf(" {"); printf(" document.pageform.editbox.style.visibility = \"hidden\"; "); printf(" document.pageform.previewbtn.value = \"Show source\"; "); printf(" previewdiv.style.visibility = \"visible\"; "); printf(" previewdiv.innerHTML = source;"); printf(" showdiv = 1;"); printf(" }"); printf(" else"); printf(" {"); printf(" showdiv = 0;"); printf(" document.pageform.editbox.style.visibility = \"visible\"; "); printf(" document.pageform.previewbtn.value = \"Preview\"; "); printf(" previewdiv.style.visibility = \"hidden\"; "); printf(" }"); printf("}</script>\n"); // file to open in browser $file = $_POST['path'] ? $_POST['path'] : "http://server/index.html"; // should be selected by user $msg = ""; // Parse the Page path ($file) // if the first part is HTTP then set $type=http else local folder $bits = explode("/", $file); if ($bits[0] == "http:") { $type = "http"; } else { $type = "local"; # $openfile= "../" . $file; $openfile= $file; } if ( $type == "http" ) { $ftp_server = $bits[2]; $filepath = ""; for($i=3; $i<count($bits); $i++) { $filepath = $filepath .
