我想根據檔案名稱刪除超過一個月的 pdf 檔案。例如,如果(今天 - 1 個月)是“2022-06-01.pdf”,那麼我想刪除“2022-04-13.pdf”和“2021-01-22.pdf”等文件。我不想根據實際修改或建立日期來確定選擇標準。
範例(臨時/)
#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 ."'"))} } } ?>
我會完全在伺服器端完成此操作。
