[Resolved] How to handle an indeterminate number of form variables?

Reapz

Hi guys,

I have a form that lists items from a MySQL database. Next to each item is a Checkbox named after the Unique ID of the database item. At the bottom of the form is a button labelled 'Delete Selected'. So as you can see the idea is to allow the user to select as many or a few of the items as they want and flag them for deletion.

Submitting this form opens a new PHP document that will list the items selected and ask for confirmation before executing the MySQL statement.

I know how to handle form variables when I know how many there are but this is the first time I've come up against an indeterminate number of them.

So the question is how do I handle this and get the result I need?

Cheers,
Andy!

Hi,
try to call it "check[]" or a name like this.
When you post the form it make an array with different value.

And put in your form an hidden with something as
value="<?=mysql_num_rows($result)?>"

see you

This should do the trick. ( at least i think so, i havent tested it)

foreach ( $_POST as $key => $value ) {
 // check the vars here
 // $key == form field name
 // $value == form field value
}

Yea it works fine thanks m8!

I'd got it working just before you posted. I thought there was something that came after the $_POST to reference the whole array so I didn't try it on it's own at first then i got bored so I tried it anyway and low and behold it worked.

I think maybe I'm overdue for a coffee break.. LOL! 😃

Cheers!
