My web form is used to allow people to register for a convention. One of the items for which registrants can sign up will be free to the first 30 registrants and $10 for each registrant thereafter. The Form Builder does not provide this capability. However, perhaps I can modify the code produced by Form Builder to allow me to track the number of registrants for this particular item and, if there are fewer than 30 registered, indicate no charge and, if there are 30 or more registered, indicate the $10 charge. Can anyone provide any guidance or direction to help me accomplish this?

Can you post a link to the form so we can view > source and look at the form code?

Hi Kirk,
Are you using a myql database to keep track of the form results?
I can't hear what I'm looking at.

Hi Eric,

Thanks for your reply. No, I am not using a database. So far, the CSV file produced by the registration process and provided by CoffeeCup has met my needs, but I figure that it is not going to get me through my current problem. I'm not very familiar with databases, but I'm certainly willing to learn. Any guidance you can provide will be much appreciated.

I can work with a csv file. Give me a bit to do some testing.

Sorry for the delay but I see your form is hosted on Coffeecup. Is it always going to be hosted there or is it only for testing? I can't do the customized php code if it's on S-Drive.

Yes, for now my only option is to host the form on CoffeeCup. However, given that I would very much like to have some additional capability that, as you’ve indicated, requires PHP, I will inquire of my organization’s webmaster about other options for hosting the form. I’ll get back to you soon.

A year later, and I'm now familiar with how to set up my form on my own server and have gained some knowledge about web applications, mySQL, and PHP. Right now I have the form working on my local machine (localhost), where I'm planning to do additional development to ready the form for the production environment.

I developed some PHP code to allow dynamic content to be placed in the form, but I'm stumped as to where I should place this code. I intended to drop it right into the HTML file that form builder generates, but then I discovered that I cannot run PHP code within an HTML file on my server. If I simply change the extension of the HTML file produced by the form builder to .php, it no longer works, i.e., the form no longer appears in the browser. It seems the code that CoffeeCup generates to initiate the form can no longer find it. So, do I need to somehow intercept the form before it is sent to the user's browser, run the PHP code to update the content, and then send it on its way to the user's browser?

Can anyone provide some guidance as to how I should proceed?

Hi Kirk,
If your using the iframe code provided by the Form Builder you have to change the src to match the extension change of your myformname.html to myformnme.php.
<iframe src="myformname.html"></iframe>

<iframe src="myformname.php"></iframe>

I will need to know what your trying to do with the php code your adding to the form. Is it for a select or an input?
