parsing variable sent by form

patrick99e99

Hello everyone!

I have a form which is posting to a php file-- this is going to be used to collect information for a paypal purchase... so I am wondering, if I do something like this:

<select name="info">
<option value="Application%20Fee!124!50.00">$50 Application Fee</option>
</select>

How is the best way to then have php examine $info and using exclamation points as a delimiter so that it can break up that variable into $item_name, $item_number, and $item_amount

Or am I making this a lot harder than I have to, and there's an easier way to pass multiple variables from a form selection?

thanks!

This will work...

$info = $_REQUEST['info'];

list($item_name, $item_number,$item_amount) = explode("!",$info);

You would be better off storing the values in a file or database, or writing an encoding function to protect the data, otherwise users will be able to change the price by viewing the source.

Of course you should always validate the data once it's been submitted too... 🆒

No probs..

Data validation can be complex... Search the forums or try 'php data validation' or something similar in google.

Well.. what's the point of this page? If you're retrieving/whatever different items, and they are selecting which item, simply store the item name, number, and price in a MySQL DB, and in the select value you'd only have the item number - the rest of the data is retrieved from the MySQL DB so that they don't have the ability to tamper with it.
