I am trying to use PHP to populate a HTML form and to retain the $_POST values to assist in editing.
Below is the script showing only two HTML input blocks - there is going to be many more!
I have unsuccessfully tried calling a common function to populate the form and would be grateful if someone could simplify the process to cater for the impending additions:
<?php
declare(strict_types=1);
# echo error_reporting();
# echo ini_get('display_errors');
# die;
$title = 'Test Data';
if(0) : $_POST = []; endif;
$_POST['xxx'][0][0] = $_POST['xxx'][0][0] ?? 'xxx00 NOT SET';
$_POST['xxx'][0][1] = $_POST['xxx'][0][1] ?? 'xxx01 NOT SET';
$_POST['xxx'][0][2] = $_POST['xxx'][0][2] ?? 'xxx02 NOT SET';
$_POST['xxx'][1][0] = $_POST['xxx'][1][0] ?? 'xxx10 NOT SET';
$_POST['xxx'][1][1] = $_POST['xxx'][1][1] ?? 'xxx11 NOT SET';
$_POST['xxx'][1][2] = $_POST['xxx'][1][2] ?? 'xxx12 NOT SET';
