Answer 1

Look into the use of explode() and POST variables.

Try something along the lines of:

// Loop over each item in the form.
foreach($_POST as $name => $value) {
    // Split the name into an array on each underscore.
    $splitString = explode("_", $name);

    // If the data begins with "minnight", use it.
    if ($splitString[0] == "minnight") {
        // Set the other desired values into variables.
        $secondValue = $splitString[1];
        $thirdValue= $splitString[2];

        // Database query goes here.
    }
}
