>= with - numbers

[lesmith]

Hello Peeps

Not sure how to resolve -hours on my date format.

I have a function which will tell me how many hours old an item is. This function is working fine but I need to apply some if statememts to it for sums. ie.

if ( $datediff <= -24 ){ // less than 24 hours old
		$cost = $cost + 1;
		$template->set_var('COST', $cost);	
		}
		if ( ($datediff >= -25) && ($datediff <= -96) ){ //  between 24 - 86 hours old  (2 - 4 days)
		$cost = $cost + 0.50;
		$template->set_var('COST', $cost);
		}
		if ( ($datediff >= -97) && ($datediff <= -240) ){ // over between old  (5 - 10 days)
		$cost = $cost - 0.50;
		$template->set_var('COST', $cost);
		}
		if ( $datediff >= -241 ){ // over 10 Days old
		$cost = $cost - 1.00;
		$template->set_var('COST', $cost);
		}

But being that my date function returns -xx figures the above will not work corectly. If I put them to <= then all would be the last if statement.

Also my starting price is
$cost = 4.00;

But only shows up 4 or 5 or xx.5 never shoing 2 decimal places. How can I get it to show this.

Hope you can help

Regards

Lee

replace all >= with <= and all <= with >=
that should solve part 1 (remember -1 is greater than -2, -2 is smaller than -1)

for formatting display use [man]printf[/man] function 🙂

As per my post this will not work.

How can -1 be greater then -2 ?

I did you as you have said and like I said it uses the last if statement.

here is the code with your changes on

if ( $datediff <= -24 ){ // less than 24 hours old
		$cost = $cost + 1;
		$template->set_var('COST', $cost);	
		}
		if ( ($datediff <= -25) && ($datediff >= -96) ){ // over between 24 & 86 hours old  (2 - 4 days)
		$cost = $cost + 0.50;
		$template->set_var('COST', $cost);
		}
		if ( ($datediff <= -97) && ($datediff >= -240) ){ // over between old  (5 - 10 days)
		$cost = $cost - 0.50;
		$template->set_var('COST', $cost);
		}
		if ( $datediff <= -241 ){ // over 10 Days old
		$cost = $cost - 1.00;
		$template->set_var('COST', $cost);
		}

And I will not be able to use printf becuase its passing the variable to a template.

Any other ideas?

Thanks Lee

Um, -1 is greater than -2. -2 is less than -1, same way that -1 is less than zero.

As for your other problem, it's mentioned in the Coding Forum's FAQ. (Also, if you read through the page jayant supplied you with a link to, you'll see a section labelled "See also". This lists related functions, maybe one of those would be closer to what you need.)
