Unique name for dynamic input form... emergency

[Anon]

HI,

this is a very hard problem for me.

i want to display a set of dynamically generated input form in this case check boxes (from mysql).
so basically i have:
$n=mysql_num_rows($result);
$c=1;
$b=box;
while($c <= $n)
{
$a=$b.$c; // which give me box1, box2 etc
$row=mysql_fetch_array($result);

print(" <input type=checkbox
name=$a> ")
$c++;
}

SO u see the problem, since i want to generate it dynamically the name property in the input type has to be a variable(in this case $a)

And when i send this to a php script to determine which box is checked, the problem occured!

i use
if(isset($box1))
//since $a value is box1, box2 and so on

/*this works fine! BUT i need to check it dynamically depending on the number of check-box generated
therefore i tried to use the same appending method as in the form page $a=$b.$c thing .
BUT it doesn't work
so if(isset($a)) Fails big time

I think i already run out of idea...

Anyone outhere who has attempted this kind of dynamically generate input form ? could you give me some idea how to do it correctly?
or is this imposssible?

thanks

What about not using check boxes but a single select sentence with a multiple ?

something like

print "<select multiple name=\"$foo[]\">";
while(data to be fetched){
print "<option>$your_result";
}
print "</select>";

Hope this helps.

(btw this is not regular php code 🙂) ).
