A _post question I guess

I have a form. It has any number of hidden fields, named "exercise 1-100". Their names all start with "exercise" as in:

<input type=hidden name=exercise1>
.... ?
<input type=hidden name=exercise11>
any number fo these possible ...
<input type=hidden name=exercise71>

How can I create one scipt that will recognise all of them? Any number of them. My idea is a bit like formmail.pl that reads any old field and mails it. Mine will read any number of "exercise" fields.

You could just loop over the _POST array.

foreach ($_POST as $field_name => $field_value) {
$content .= "$field_name = $field_value\n";
}

Then just email $content. You could filter out the excerciseN fields if
you only wanted to send those.

name them as name="exercise[1]"

then do

if(isset($_POST['exercise'])){
foreach($_POST['exercise'] as $key=>$val){
echo 'Key '.$key.' val '.$val.'<br>';
}
}

Ok, but the problem is that I will, might have other fields. I need to filter out just the exerciseN fields. Interesting though thanks,

Then just look at $feild_name and see if it is one of the 'exercise' fields.

foreach ($_POST as $field_name => $field_value) {
if (stristr($field_name, 'exercise')) {
$content .= "$field_name = $field_value\n";
}
}

Brad. Perfect thanks.

Tom, Not sure why, but wouldn't work

Thanks all.
P.S. I try to surf and contribute when I see something I can answer.
