The solution to the non-existence of phpcms images: first find and open the "attachments.php" file; then change "if (empty ($this- > userid)) {" to "if (empty ($_ POST ['userid'])) {".

PHPCMS v9 upload picture prompt "undefined" solution

Add phpcms\ modules\ attachment\ attachments.php

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

Change it to if (empty ($_ POST ['userid'])) {

Because $this- > userid must be empty when submitting, but it is used when calling

$attachment- > set_userid ($_ POST ['userid'])

And $_ POST ['userid'] is the data of userid.

So change $this- > userid to $_ POST ['userid'].
