It all seems to be going well except for one part.</p> <p>The general logic of what I'm attempting to validate is the amount of emails that can be supplied for a given quantity. For example, if a value of 5 is picked, the user can "opt-in" allowing only 4 emails to be added to a text area. So far my validation works for not enough emails, too many emails, and just enough emails supplied. I however cannot figure out for life of me how to grab the value of a check-box during a validation hook in order to subtract it from the quantity value.</p> <p>Here is a look at my code : <a href="http://pastie.org/3998833" rel="nofollow">http://pastie.org/3998833</a>.</p> <p>Basically, rgpost("input_3") is the quantity set. I pass that through to something strips whitespace, explodes emails and validates them, then checks to see if the number of emails supplied matches quantity. </p> <p>What I would like to be able to do is grab "Content-Disposition: form-data; name="input_4.1" online_self", check if it is in fact set to "online_self" and if it is, subtract one from the total amount of emails. </p> <p>Whenever I try to rgpost the input, everything breaks (I get php errors). Maybe I'm using the wrong way to call the input?</p> <p>If anyone can point me in the right direction, it would be much appreciated.</p> <p>Thanks!</p> <p>As part of my validation, I need to check to see if an input is checked or not. If it is, I need to subtract 1 from a number (namely the maximum quantity). </p>
