I am trying to process a form where the user uses checkboxes:

<input type="checkbox" name="painDesc[]" value="1" />Sharp
<input type="checkbox" name="painDesc[]" value="2" />Stabbing
<input type="checkbox" name="painDesc[]" value="3" />Jabbing

When I do:

foreach($_REQUEST as $key => $val) {
$$key = $val;
echo $key . ": " . $val . "<br>";
}

The output is:

painDesc: Array

I need to know the values of the array (IE to know what the user is
checking), not that there is an array. I hope to save these values to the
database.

Thank you.

Ron

You need to iterate that array, as that holds the values of everything
sent by the browser

The painDesc array is what that should be iterated.

Am I on the right track? I don't know what to do with the second "FOREACH"

<?php

foreach($_REQUEST as $key => $val) {
$$key = $val;
echo $key . ": " . $val . "<br>";

if ( $val == "Array" ) {
$i=0;

foreach ($val) {
echo "$val[$i]<br>";
$i++;
}

}
}

?>

Think about it...

You would not <?php echo $_REQUEST; ?> and expect to get the value of any form
field would you. No, you wouldn't.

Given the following form...

<form>
Title<input type="text" name="title" value="" /><br />
Subject<input type="text" name="subject" value="" /><br />
<input type="submit" name="submit" value="Send it!" />
</form>

on the processing page, I would access those variables by writing the following.

echo $_REQUEST['title'];
echo $_REQUEST['subject'];

With that said, going back to your issue, you would do this:

if ( $_REQUEST['painDesc'] && count($_REQUEST['painDesc']) ) {
foreach($_REQUEST['painDesc'] as $key => $val) {
echo "{$key}:{$val}<br />";
}
}
