variable gets any number put to it..

[Dragen]

Hi,

The title for this topic isn't very helpfull, but couldn't think of a better one..

I've got an online form which Im writting an error check for it. I have several inputs with the names 'download%' where '%' is a number.

Is there a way of getting a statement to check all downloads with any number at the end?

What I've got is a foreach statement checking all inputs, with a switch to get the names of each post.

<?php
foreach($_POST as $key => $value){
switch($key){
	case 'download1':
		//do something
	break;
	case 'download2':
		//do something
	break;
	case 'download3':
		//do something
	break;
}
}
?>

now instead of doing a seperate case for each download (as they'll all be identical) could I somehow have it so the one case gets all of them with a number check of some sort?

so the % counts as any number, so any post titled download followed by a number will be checked by the same case statement..

<?php
foreach($_POST as $key => $value){
switch($key){
	case 'download%':
		//do something
	break;
}
}
?>

I might have misunderstood you, but can't you use preg_match() to fetch out the number from the input then deal with it accordingly..?

I could, but then I'd need another statement to find that.

At the moment, when I submit the form it goes through each post using the foreach. I've got different cases for each post variable such as:

				case 'time%20period':
				if(array_search($value, $timepa) === false && $_POST['time%20num'] != ''){
					$error[$erid] = "Please select the length of advertising (week, month) from the drop-down box"; //adds the errors to an array
					$erid++;
				}
			break;

I don't want to check what number the download input is, then do something with it, I want php to run through all of the inputs as it's doing but for the 'download%' to capture any of the downloads (download1, download2, download3 etc) without having to set a number to the case like this:

case 'download1':

I thought there might be a simple function that simply reads any number in a given string..
