You guys are completely awesome. That was the problem. I have one
quick parting questions. I should probably just start a new thread,
but since you all seem to know your stuff, I thought I would ask here
first.
I have been playing around with the form, using radio buttons instead
of text boxes. The problem I am having, is that within the while loop
that displays the question for the number of times a user specifies,
all occurrences of that question use the same name for the radio
button. Here is the while loop:
while ($Number!=0){
<input type="radio" name="Age[]" value="20-30">20-30
<input type="radio name="Age[]" value="30-40">30-40
<input type="radio name"Age[]" value="40-50">40-50
$Number--;
}
Let's say someone entered 3 for $Number. When the loop executes it
would produce:
<input type="radio" name="Age[]" value="20-30">20-30
<input type="radio name="Age[]" value="30-40">30-40
<input type="radio name"Age[]" value="40-50">40-50
<input type="radio" name="Age[]" value="20-30">20-30
<input type="radio name="Age[]" value="30-40">30-40
<input type="radio name"Age[]" value="40-50">40-50
<input type="radio" name="Age[]" value="20-30">20-30
<input type="radio name="Age[]" value="30-40">30-40
<input type="radio name"Age[]" value="40-50">40-50
The problem is that with radio buttons, you can only choose one
option. With this code, it only allows the user to choose one option
from among the 9 listed, instead of one from each set. Since it really
needs to be radio buttons, I am trying to find a way to dynamically
name each set. Would something like this work:
<input type="radio name"Age<?php echo $Number ?>[]"
value="40-50">40-50
But that would seem to negate the whole need for arrays, which you all
were so patient in teaching me. This may be more of an HTML question
as how to define sets of radio buttons.
