In a module i am working on, I have a form on the admin page to update records in the DB. A part of this form is generated dynamically based on what is in the database for that record.


Kinda like the phpbb poll form. Where it generates x number of fields depending on how many questions you have in your poll.


My question is, how do I pass those variables from the form to the update function? I'm working from the example module and the way that is set up, I need to list all the varibles before I can use them. But I obviously cannot do that if I don't know how many variables there will be for a given record.

Here is the piece of code I'm talking about:



Is there a better way I should be doing this? Any advice would be great. thanks.

In your template form, use inputs with names such as:



That way, in the PHP (update function) you can simply grab a single variable as:



...this will grab all the form data in a nice, neat single variable, no matter how many (or few) fields there are.

If you don't know how many rows there will be, you can use arrays. In your form, in the input, textarea, select rows; use as your parameter....



Then in your PHP code.....



Then use a foreach statement to loop through them.

The method I posted is /somewhat/ the same, but uses less code.

We both were writing our methods at the same time; but yes, your way would be more efficient. I would have suggested that method, but I think I read too much into rowjow's question. I thought he was asking how to do 'x' rows with 5 fields per row and my method has been the only way I have come up for that type of a complex form. I've used your way many times myself for simple 1 field per row forms.
