prompt for completion

[eco]

Hi all,

 

I hope this is the right place for this post.

 

I have an application that will write data to a db but if information is missing, the user should be prompted to complete the data before being submitted to the db.

 

The prompt would originally have two combo boxes and a search field (Category, sub-category and search paten).  If a cat or sub cat does not exist, by selecting 'new' one should be prompted with a text box to add a row to the drop down.  The dropdown are picked up from the db.

 

I was thinking of using a popup for this but I think (still very much a newb so correct me if I'm wrong) a form can only send a single 'item' be it a variable or an array but not two or more.

 

I was just wondering how you would go about prompting a user for more information and then returning to the original screen in the original state it was in.

 

Thanks for any advice.

An HTML form can send as many pieces of information as you want.  For each field in the form you want to get the data out of, add the 'name' attribute.  Then the php script that receives the data can that information through the $_GET (or $_POST, or $_REQUEST) superglobal array.

I hope I understood your question correctly.
