Question

I have a form where text fields are created dynamically with the names unknown. I am trying to get those text fields names and values and using the following PHP code.

foreach ($_POST as $key => $entry)
{
     if (is_array($entry))
     {
        foreach($entry as $value)
        {
           print $key . ": " . $value . "<br>";
        }
     }
    else 
     {
        print $key . ": " . $entry . "<br>";
     }
}

But the problem is that it gets all the hidden fields and submit button values as well. How can I prevent that from happening?

Answer 1

foreach ($_POST as $key => $entry)
{
     if ($key == "button_submit") continue;
     if ($key == "hidden_field") continue;
     if ($key == "hidden_field2") continue;
     if ($key == "hidden_field3") continue;
     if (is_array($entry))
     {
        foreach($entry as $value)
        {
           print $key . ": " . $value . "<br>";
        }
     }
    else 
     {
        print $key . ": " . $entry . "<br>";
     }
}
