我如何检查是否上传PDF文件的密码保护或不同时使用PHP上传多个文件? 我想说明一个错误,如果它的密码保护。
Answer 1:
我在网上找到了一个类似的帖子看看。
http://drupal.org/node/843516
/**
* Check whether pdf is encrypted or password protected.
* @param <type> $form
* @param <type> $form_state
*/
function pdftest_is_encrypted($form,&$form_state) {
include_once 'sites/all/libraries/fpdi/pdf_parser.php';
foreach($form_state['values']['files'] as $value) {
//Check whether file type is pdf and confirm the file is selected to remove.
if($value['filemime'] == 'application/pdf' && $value['remove'] != 1) {
$pdf = new pdf_parser($value['filepath']);
if(stristr($pdf->errormsg,'File is encrypted')) {
form_set_error('field_attachment', t('Uploaded PDF Document '.$value['filename'].' is encrypted and can not be uploaded. '.l('Guide to troubleshooting failed uploads.','http://support.scribd.com/forums/33627/entries/24412')));
}
}
}
Answer 2:
这个问题是一个变化是有可能检查PDF使用ghostscript的密码保护? (你可能只需要执行只要shell脚本,这依赖于ghostcript)
