Dynamic Form Variables

[Anon]

I have a page drawn from a MySQL database.

There are a variable amount of items per day in the database. I am making a checkbox toggle on the specific ID of each. Due to the different number of items in the database, how do I know on the next page how to parse these variables?

Here's a clearer example. The number of "items" will change depending on date:

<INPUT TYPE="checkbox" VALUE="item1" CHECKED></DIV></TD>

<INPUT TYPE="checkbox" VALUE="item2" CHECKED></DIV></TD>

<INPUT TYPE="checkbox" VALUE="item3" CHECKED></DIV></TD>

...

<INPUT TYPE="checkbox" VALUE="item10" CHECKED></DIV></TD>

After submitting the form, how do I know how many "item" variables there? Can the input values be accessed through an ENV variable?

If you aplly a name attribute to the checkboxes ie name="items", then you will get an array called $items on your processing page, which you could then access. You could access the speciifc number by using something like:

$itemcount = count($items);

When I have a multiple fields with the same name I put a [] after to make php understand it is an array.
This applies to checkboxes as well as multiple selectboxes.

<INPUT TYPE="checkbox" NAME="item[]" VALUE="item1" CHECKED>

<INPUT TYPE="checkbox" NAME="item[]" VALUE="item2" CHECKED>

<INPUT TYPE="checkbox" NAME="item[]" VALUE="item3" CHECKED>

On the recieving page you could do diffrent things with the array.
Loop through them:
for ($i=0;$i < count($item); $i++)
{
echo $item[$i];
}
or make a text string with implode:
$items = implode($item, ",");

hope this helps
