Answer 1

I’m unsure what you mean about “using class”, however you can loop the $_POST array to get access to the variables like so:

// Show the variables
var_dump($_POST);
// Loop the variables
foreach($_POST as $k => $v){
    echo "{$k} = {$v}";
}

Alternatively you can group your vars together in your HTML like so:

<input id="op1" name="po[1]" class="key" size="50">
<input id="op2" name="po[2]" class="key" size="50">
<input id="op3" name="po[3]" class="key" size="50">
<input id="op4" name="po[4]" class="key" size="50">
<input id="op5" name="po[5]" class="key" size="50">
<input id="op6" name="po[6]" class="key" size="50">

Which then means that PHP sees the POST variable po as an array, like so:

// Show the variables
var_dump($_POST);
// Loop the po variables
foreach($_POST['po'] as $k => $v){
    echo "{$k} = {$v}";
}
