[PHP] dynamic checkboxes?

[garman]

I have a form that generates a list of categories dynamically.  That is, for 
each category in a database, the form has a corresponding checkbox.  The 
checkboxes are given serialized names, such as chkbx1, chkbx2, etc.

I'm having trouble figuring out how to process these in the php script that 
handles this form.  In other words, how do I figure out which categories were 
selected when I don't know in advance how many categories there are?  How can 
I check if the form variables chkbx1, chkbx2, etc have been set?

Thanks,
Matt

name them chkbx[1], chkbx[2]...

then on the next page go:

foreach($chkbx as $key=$value){
echo chkbx[$key] is set.\n;
}

[PHP] dynamic checkboxes

[Nando2]

Hello All,

I'm trying to build a way to transfer my orders to a HTML page instead of using GUI 
that I've designed.

In order to do that I need to display all the orders of the day and have checkboxes on 
each so that the user can select only the orders that we will process. 

The number of checkboxes on this form will depend on the number of orders of that day. 
So the form and the number of its variables will be dynamic as well.

Each checkbox has to have the name property that can be matched to the 
customercode+ordernumber. After the form is submited I need to scan all the variables 
that were checked so that it can be included on the next query.

Has anyone tried that or did that before? Is there any URL or PHP code that can be 
used to learn that?

Thank you very much,

Carlos Fernando.

What you need to do is to have a function in the form processing page that
iterates through $HTTP_POST_VARS and saves the name and value of each item
in the form.  You will want to exclude your submit button and if there are
other form items you don't want to save, you might want to name them with a
unique name (such as prepending "nosave") so you can exclude them as well.

The function I wrote to do this is as follows:

 function SetAllAnswers()
 {
  global $HTTP_POST_VARS;
  foreach($HTTP_POST_VARS as $qID=$value)
  {
   if ($qID != 'submit'  !stristr($qID,'nosave'))
$this-SetAnswer($qID, $value);
  }
 }
