How about something like:

select count(*)
from students
where total_raised > (select total_raised from students where uid=$uid)

While a form using the post method is less obvious then the ?id=xyz in the url, they're both just as hackable. If you want to verify (assuming you're running windows), check out Microsoft Fiddler,...

No problem! FYI, you can pass multiple variables by doing:

whatever.php?id=5&variable2=whatever&xyz=aaa

Just build each link like:

<a href='editform.php?id=53'>John Doe</a>

Maybe use something in javascript along the lines of:

function validateImage(url){
var img = new Image();
img.src = url;

Smarty (http://smarty.php.net) is a pretty good templating system that you can use as part of a flat file db system. You'll still need to store the editable data somewhere -- flat file or db -- and...

Here's one, although the latest version is not yet available

Well, I'm not at all familiar with XFORMS, but you can use (assuming you're under Windows) Microsoft Fiddler to examine the data transferred. You can pick up the headers that are normally sent from...

The mysqli code is causing a fatal error (not sure that it's available in PHP 4.x), and stopping the rest of the script from executing. If you remove the "@" from in front of the line, you will see...

What database software are you using? Some have full text search capabilities which are quite neat. You could search for "styles" or "styling", and it would match "Style", because they're related....

well, all you need to keep track of then is the sum and the number of ratings so that you when you get a new rating, you'd just do

UPDATE ratings SET sumRatings=sumRatings+{$newRating},...

yup, either way is probably fine -- whichever way works.. I can't see any benefits of doing it one way or the other

check out php's array_values function, which will essentially reindex the arrays

Using Microsoft Fiddler (great program for some debugging and such!), I can see that your server is indeed doing what Puckdropper said .. no content type in the header.

Your server's return...

Well, what would you like to do when the feed is not available? I'm assuming that there is something else that the page will display... You're on the right track, basically (without knowing more...

First Issue:
You can use:

list($month,$day,$year)=preg_split("/[,\s]/",$date); // (untested!)


or you can use the strtotime() function, which will convert it to a php datetime, and then do...

I think the standard way is to check the file extension, or to check the mime type.

Of course, none of this guarantees that the uploaded file is a valid "audio" file. (What is an audio file for...

...or in php use setcookie (http://ca3.php.net/manual/en/function.setcookie.php)

I'm assuming you're looking for the PHP code =)

If you wanted to use php functions to do the validation (say against database entries and such), then you might want to consider using an ajax library such as xajax, and make it look spiffy using...

Silly question, but do you want SAM to be the only valid response? As written above, SAM will always return the error message, and anything else (even if MSelect is not specified) will continue...

Actually, if you have


<?php
header('Content-type: application/msword');
header('Content-Disposition: attachment; filename="file.doc"');
readfile('file.doc');
?>
