Help with dynamically assigned ID's

[Csanád]

Hello,

I have a form:

http://www.steinrogan.com/SecureSite...em_single.html

The idea is that every time the "Add a Dependant Item" button is clicked, the Item whose "Add a Dependant Item" button was clicked will have an additional field for another Dependant Item.

Similarly, when the "Add Another Item" button is clicked, the form will have another Item with all the usual fields.

How do I make it, so if I add a Dependant Item, it will be added to the Item it belongs to? As of now, if any of the "Add a Dependant Item" buttons is clicked, then the last added Item will be the one who will have a new field for a Dependant Item...even if I clicked the very first Item's "Add a Dependant Button."

More importantly, when all is said and done and sent to the server, how will the server know which Dependant Item belongs to which Item?

Thanks very much for your time!

Have you solved this problem?

Is the numbering supposed to continue even when you remove dependent items?

I've solved the first issue re: dependant items are placed where they belong.

With regard to numbering when you delete a dependant item, I haven't come up with an idea as how to renumber. Actually, renumbering is not that necessary and I can even remove the index from the title of each dependant item.

But my bigger problem is, how do I pass the following info to the server:

How many items/dependant items were added altogether?

How many dependant items does each item have?

I'm using PHP on the server-side.

Thanks for your help!

You can do this by using hidden elements. Just update them when you add/delete items.

How do I do that? How do I assign/update the value of the hidden elements?

Thanks.

Thanks.

Give them an id (as well as a name for the server-side script), then use

document.getElementById(hidden_element_id).value=whatever;

to update the values. I assume you know that by hidden elements I mean input type=hidden form elements.
