IF statement problem...

[dle46163]

Hi!

I'm trying to format an if statement for OsCommerce like this:

if ($products_price != "$0.00"){
echo $products_price;
}

For testing, I can just echo $products_price and it will show me $0.00. However, when I put the IF statement in, it acts as if $products_price never equals $0.00! I know in this instance it does equal $0.00 BUT it never acts that way! Is there maybe some sort of currency variable type that could be causing this? I just need to do a simple compare... Any feedback would be great!

Are you sure it's got the dollar sign in there? I recall that OSCommerce is very language- and currency-agnostic, so it seems unusual to me that the currency character would be included in the string.

That's what seemed odd to me too... If I straight out echo $products_price it gives me $0.00!

Perhaps I'm missing something obvious, but I don't see the problem.

Your code above says, if $products_price does NOT equal $0.00 then print the price.... but if you just straight out print it it does equal $0.00

PHP supports neither the creation of new types nor the overloading of functions, so if echo says its there, I'll take its word for it.

It's been a while since I worked with OSCommerce, so forgive me if I seem like I'm grasping at straws.

If you issue the command:

echo '"' . $products_price . '"';

does it show any spaces at the beginning or end of the string?

I had tested the space thing and there were no spaces...I even went as far as doing a str_replace on the dollar sign so I was simply left with the numbers and decimal. After all that I still couldn't get the IF statement working!!

Soooo, I tracked down the variable at the point it gets assigned values and turns out it's a huge string of junk including multiple variables and HTML code... Even though the echo statement was spitting out $0.00 the variable certainly was not just set to $0.00. Thus, I was able to find a different variable (within the $products_price assignment) which actually held the dollar amount I was looking to compare in my IF statement. I used that and sure enough it works! Pretty strange I guess...I've never done code that way but it appears to work just fine. Thanks for all your help!
