Strange Form Happenings...

Perloe

I'm working on a site where people can order food online. I have a menu page with a text input field next to each item where people can type in how much they want of that item. Once they hit submit, the whole form is submitted to a script page which will process it.

The problem I'm having is that underscores ("_") keep being substituted into all my spaces. For example, the name of one of the fields on this form is:
"House Pizza (small)|5.50"

When the form is submitted, I am running this script:

foreach ($_POST as $key => $value) {
		if ($value > 0) {
			// break up the key string into price and item
			list ($item, $price, $type) = split ('[|]', $key);

	}
}

which returns this:

Array ( [House_Pizza_(small)|5_50] => 0)

It seems to automatically be putting in underscores in places of spaces and decimals. Any ideas why it is doing this?

easiest thing that i can think of now, is just to replace the _ with a " ".. i know theres a function in php to encode spaces.. i just cant think of it (urlencode? i think that puts a +, then urldecode??)

this could work as a temp fix though

preg_replace("/\_/"," ",$key);
//or
string replace

Thanks for the workaround. It seems to work. It's strange though why it puts in underlines for spaces. I've never encountered that problem before.

Thanks for your help!

Go to the "Dots in incoming variable names" section.

Actually, may I suggest that you do not include the price in the variable name (i.e. the field name)?
It probably would be better to keep the item name separate, then use some sort of database to lookup the price.
In your current setup, it might be possible for someone to write a form to buy items for free.
