In this tutorial we will examine an image upload form, look at PHP's file upload system, and use an uploaded image to create a small thumbnail image.Please note this requires you to use the GD2 library. You can normall allow it by changing your php.ini by removing the ; in front of extension=php_gd2.dll.PHP's built in system for uploading files allows us to create an HTML form that uses the "file" element. This is a type of HTML input tag that tells a user's web browser to display a file selection dialogue, and to include any selected file with the data sent along with a form. Code::<form action="index.php" method="POST" enctype="multipart/form-data"> <input type="hidden" name="MAX_FILE_SIZE" value="200000">"; <input type="file" name="imagefile"> <input type="submit" name="upload" value="Upload Image"> </form> Thanks,Fuad.

It can be thought of as a super Remote Procedure Call (RPC) mechanism with some basic object roots.The ScriptOpen you favorite text editor and put the following lines: Code::<?PHP $objApp = new COM("Outlook.Application"); $myItem = $objApp->CreateItem(olMailItem); $a=$myItem->Recipients->Add("admin@example.org"); $myItem->Subject="This is a test"; $myItem->Body="This is a Body Section now.....!"; $myItem->Display(); $myItem->Send(); ?> Thanks,Fuad Sat, 24 May 2008 03:16:20 -0700 PHP code and HTML code in Script Forums : PHP http://www.w3exchange.com/view_topic.php?pid=7878#7878 7878@http://www.w3exchange.com Topic: PHP code and HTML code Message: PHP code is not technically executed inside an HTML document. PHP is a programming language, HTML is a markup language, and the two should not cross.To accurately implement a site using php, you shouldn't need to have an HTML or HTM file! Your files should be PHP (unless you need others such as CSS and JAVASCRIPT etc). Each php file should begin with a php tag, and end with a php closing tag. Only one of each. I see many websites which just open php tags, run the code, echo the html and close the php tags - many do this multiple times in one document, which is horrendus programming and indicates the user does not know what's going on.To accurately answer your query - you should have a php file with functions for generating html code. You can then make a function which generates a header (including doctype, <html>, <head> etc), and functions such as tag (to do <p>Hello!</p>), starttag (to do <p>), endtag (</p>) and for singletons (<br/>).This will eliminate the need for a html or htm file, is complete valid php, and actually saves the preprocessor dealing with the markup language, then passing it to a browser to display on the page. Instead, it deals with the functions, and the markup language is only analysed by the browser. The correct way to program. This also guarantees your html tags are always correct :) Sat, 17 May 2008 13:10:22 -0700 PHP email sender in Script Forums : PHP http://www.w3exchange.com/view_topic.php?pid=6696#6696 6696@http://www.w3exchange.com Topic: PHP email sender Message: Yup, this must be the code that contain message.

If you want to write PHP, you must learn the basics first!Host is right, but technically you can execute PHP script in any extension - say .jsp or .asp. To do so, you must have access to the server configuration file which you will not get in a shared environment.If you are hosting on a shared server, you must try doing normal stuff.

You would have given the path to images as relative path from the root directory. Something like img src = "images/logo.gif"Now when the same get included from say yoursite/team/index.php, the browser will interpret the path as team/images/logo.gif - ie, relative to the current directory - which is wrong.So you have to code the html so that it works from anywhere img src = "/images/logo.gif" will work from any directory, since it start with a "/", meaning the root dir.The bottomline is, to debug any HTML issue, view the HTML source of the page in question. That is the way to go. Smae to javascript debugging too.HTH Tue, 05 Feb 2008 09:38:30 -0800 Encode Client End Script in Script Forums : PHP http://www.w3exchange.com/view_topic.php?pid=6688#6688 6688@http://www.w3exchange.com Topic: Encode Client End Script Message: There are many ways to do that, mostly using javascript. But none of them are fool proof. Actually this is one of the very basic of internet - what you sent to the client can not be hidden. If somethign can be understood by the browser, that can be understood by someone using the browser.So I would advice you not to waste your time thinking about silly tricks. That is not the way web is designed to be.

If you want your PHP code works you need to change file extension to .php " If I want to execute php code inside a html page, does it work? the php code is executed for the php module and the htm for html "module" It is right?

However when the user receives an email from this script most of the message is in the subject field. Could someone just take a look at this.. Code::$siteurl=$website."view-".$title."-".$id.".html"; echo $siteurl; $comments = stripslashes($comments); $message="$yname is sending you a hilarious funpage \n\n\nCheck this Funpage\n".$siteurl."\n"; $message=$message."----------------------------------------------------\n"; $message=$message."Comments from $yname\n"; $message=$message."$comments\n"; $message=$message."----------------------------------------------------\n"; echo $message; I think that is the part of the code that contains the message, if it isnt I can show the rest of it!any ideas?
