Here's some of the code that the person wanted.
The first part makes the form
...
echo "<form name=\"form\" action=\"people.php\" method=\"post\">";
echo "<table>";
$guest_number_temp = $guest_number;
while($guest_number >= 1)
{
echo "<tr><td colspan = 2>";
echo "Please enter in the person's first name:
</td></tr>";
echo "<tr><td>
<input type=text name=guest_firstname[$guest_number] ></td></tr>";
echo "<tr><td colspan = 2>";
echo "Please enter in the person's last name:
</td></tr>";
echo "<tr><td>
<input type=text name=guest_lastname[$guest_number] ></td></tr>";
echo "<tr><td colspan = 2><br>";
echo "Does this person needs a hotel room?: </td></tr>";
echo "<tr><td>
<input type=radio name=guest_hotel[$guest_number] value=\"yes\">Yes";
echo "<input type=radio name=guest_hotel[$guest_number] value=\"no\">No";
echo "</td></tr>";
...
The second part is located inside of my checker for null values
...
$null = false;
global $guest_number;
$guest_number_holder = $guest_number;
while($guest_number >= 1)
{
//the guest number index is the position in terms of what the user sees and not the computer
$guest_number_index = $guest_number_holder - $guest_number + 1;
if(
!isset($guest_hotel[$guest_number])
||
('' == $guest_hotel[$guest_number]))
{
echo "<div id=red-asterk>Please inform us if guest number $guest_number_index needs a hotel room.</div>";
$null = true;
}
if(
!isset($guest_firstname[$guest_number])
||
('' == $guest_firstname[$guest_number]))
{
echo "<div id=red-asterk>Please inform us of guest number $guest_number_index first name.</div>";
$null = true;
}
if(
!isset($guest_lastname[$guest_number])
||
('' == $guest_lastname[$guest_number]))
{
echo "<div id=red-asterk>Please inform us of guest number $guest_number_index last name.</div>";
$null = true;
}

: : Either I don't understand you or you don't understand me.
: : I will further the information. I need to get a "Yes" or a "No" from the user. I will use radio buttons just like in the rest of the site. Since these button values depends on the amount of people from the previous form, I have to use an array as the variable.
: :
: : I did made a new discovery. Regardless how many items the array is SUPPOSED to have, if at least one is filled in, there is no error. What I meant by SUPPOSED is that if the amount of people is 20, the array should be of size 20. However, if the user only fills in the information for at least 1 person, then there will not be a notice about
: : uninitialization string and my error checking works with isset(). However, if none is set, then the problem occurs with isset(), empty(), etc. Any call to array(index) will result in an error since nothing is inside of the array. But if one thing is inside of the error, then the index is simply not set. So, how do I see if anything is in an array? Without printing it out, but checking
: :
: : count(), this did not work, it gives the value of 1. Does this help you to understand my situation?

: Yeah, sorry, I just skimmed(don't know if that's a word...) through your post. I'm to tired...

: OK, your prob seems to be some langauge thingy, and as I don't know php very well I can't help very much.

: But I'm still curious, post your code.
