My point exactly! So long as the name of the name[] part is the same they will be treated as the same "group" of radio buttons. So here is the long and short; if the name is the same and you specify an index then names with the same index will be grouped together: name[1] and name[1] are the same but different group from name[2]. If you don't specify an index, but the name is the same, then they are grouped together: name[], name[]. By grouped together I mean that only one of the group can be selected and therefore successful on submit. -- Thanks! -Shawn Yeah, that's clear as mud -- I know how to do it and that confused me. :-\ Here's a much simpler example than my previous one: http://rebel.lcc.edu/sperlt/citw229/sticky-radio.php You don't even need an array. Just check the "choice" variable. Cheers, tedd -- --- http://sperling.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi guys,
I have a form that has a long list of radio-bottons inside of it. The
radio-buttons are dynamically created via php and MySQL.
Here is an example of one of the radio buttons:
"
value="0">
"
value="1">
Now, when I submit this form to another page for processing, how would I "catch"
the above radio-button's $_POST name since I do not know the name, only that it
starts with "radio_" ?
foreach ($_POST as $k => $v) {
if (substr($k,0,6) == 'radio_') {
echo 'Name is -> ',$k,'';
// Do stuff...
}

loop thought all the $_POST variables...
foreach($_POST as $key => $val)
{
if(susbtr($key, 0, 7) === "radio_")
{
# this is what we're looking for
}
}
crude, but works... I am sure there are many ways to look for it.

One method is a foreach() loop.
$v) {
if (preg_match('/^radio_/Ui',trim($k))) {
echo $k.' is a match, and it\'s value is '.$v.'.'.PHP_EOL;
}
}

[PHP] $_POST variable
