I would like to use a dropdown menu to allow the selection of a set number of three textboxes where each number set of textboxes should contain a unique set of numbers. Currently, the dropdown menu does create the desired number of sets of textboxes, for example, selecting 5 generated a set of 5 textboxes filled with random numbers. The problem is that they are all the same sets of random numbers.
I would like something where a selected number in the dropdown menu would generate the desired sets of textboxes, then clicking on a Generate Numbers button would fill the sets of textboxes with random numbers where each set is unique. Can this be done with Javascript, JQuery or do I need to use something else?
Here's my code so far. Thank you very much for your help.
<?php
//generate set of random numbers from 1 to 10000
function RandomNumbers($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
return array_slice($numbers, 0, $quantity);
}
$num = (RandomNumbers(1,10000,10000));
$random1 = $num[0];
$random2 = $num[1];
$random3 = $num[2];
?>
