What should I do if pictures cannot be uploaded in the phpcms background?

The solution to the problem that phpcms cannot upload images in the background: first find and open the "attachment.class.php" file; then replace "if(empty($this->userid)){" with "if( empty($_POST['userid'])){" is enough.

##phpcmsSolution to the problem of unable to upload images in the background

PHPCMS V9 has a code inference error in the latest updated version number (9.4.2). A bug that caused PHPCMS to be unable to upload images when updating articles in the background. I found a temporary solution in the PHPCMS forum. I hope that the PHPCMS official can announce the update package as soon as possible, so that many other webmasters can save trouble and effort.

if(empty($this->userid)){

if(empty($_POST['userid'])){
