Passing Values based on a for loop

lulubell

What I'm trying to do (in English!)
If a user types in 2 into the field movefrom_lounges, the next form does a for loop which shows a list of text fields. The list will be displayed 2 times (as this was the number that was passed). I have got this bit worked out below:

for ($i=1; $i <= $movefrom_lounges; $i++)
{

$seater2= "2seater_lounge$i";
echo "<TR><TD WIDTH=50>INPUT TYPE='text' NAME='$seater2' SIZE=4 MAXLENGTH=2></TD></TR>";
}

If the movefrom_lounges was 2 on the first form, then the above row is shown twice. The first input text field's NAME is 2seater_lounge1, the second is 2seater_lounge2

The problem I have is trying to pass the value of 2seater_lounge1 or 2seater_lounge2 to the next form.

I have tried many combinations, but this is what I have on the third form:

for ($i=1; $i <= $movefrom_lounges; $i++)
{
echo "<INPUT TYPE=\"hidden\" NAME=\"2seater_lounge$i\" VALUE=\"$2seater_lounge$i\">";
}

Any ideas how I can pass the data?

Any help in the right direction would be most grateful.

Usually in this situation, I would pass the number of values in a hidden field(in your example, $i). Then on the next page, loop through them again, based on that number to check their values.

Do you mean leave the code as it is on the second form, and on the third form use:

while($code < $possibilities) { $code++; }

when I am inserting the hidden fields?

No....
while($code < $possibilities) { $code++; }
is my signature.....

I'm sayign that on the second form, make a <input type="hidden" name="count" value="<?=$i?>">sorta field to pass the count to the third page. And on the third page, do something like this

for($i=1;$i<=$_POST['count'];$i++) {
   if(isset($_POST['2seater_lounge'.$i])) {
      // do something with this info
   }
}

Sorry about that...

Still not working though, I've put the $count on the second form, and the code you said on the third form, however when I ask it to create a hidden field with the value of 2seater_lounge$i it doesn't return the value.

I asked it to :

echo "<INPUT TYPE=\"hidden\" NAME=\"2seater_lounge$i\" VALUE=\"2seater_lounge$i\">";

and changed the value to $2seater_lounge$i but it doesn't pass a value. Even when I ask it to ech0 "2seater_lounge$i" or echo "$2seater_lounge$i" it doens't reurn the value passed on the second form.

Any ideas...
