I have pdf files that I want to delete based on the file name that aremore than a month old. For example, if (today - 1 month) is '2022-06-01.pdf' then I want to delete files like '2022-04-13.pdf' and '2021-01-22.pdf'. I don't want to base the selection criteria based on actual date of modification or creation.
SAMPLE (in temp/)
2019-02-01.pdf
2020-07-01.pdf
2021-03-10.pdf
2021-08-04.pdf
2022-03-30.pdf
2019-02-27.pdf
2020-07-08.pdf
2021-03-17.pdf
2021-08-11.pdf
2022-04-06.pdf
HTML
oldFiles(); purgeOLD();
JS
function oldFiles() { // this is ok
yesterday = new Date();
yesterday.setDate(yesterday.getDate() - 30);
actualYear = yesterday.getFullYear();
actualMonth = yesterday.getMonth() + 1;
actualDay = yesterday.getDate();
if (actualMonth < "10") {actualMonth = "0" + actualMonth;}
if (actualDay < "10") {actualDay = "0" + actualDay;}
backtrack = actualYear +'-' +actualMonth +'-' +actualDay;
}
function purgeOLD () { // is this where the problem is ?
var new_data = backtrack; var data;
$.ajax({url: 'test.php', type: 'post', async: false, data: {user: new_data}});
}
PHP "test.php"
<?php // or is this ?
$result = $_GET['user'];
$rdm = $result .'.pdf';
$glob = glob("temp/2???-??-??.pdf");
foreach($glob as $file) {
if ($file < $rdm) {
{unlink('/home/example/public_html/temp/' .$file ."'"))}
}
}
?>
I would do this entirely server-side.
DateTime instance for "1 month ago"$lastMonth = new DateTimeImmutable('-1 month');
$cutoff = sprintf('%s.pdf', $lastMonth->format('Y-m-d'));
$glob = glob("temp/2???-??-??.pdf");
foreach($glob as $file) {
if (basename($file) < $cutoff) {
unlink($file);
}
}
