No new download in frontend for "Registered" User group [solved]

[Sien]

Hi,

Running PHP 8.0: When an user in de user group Registered is trying to add a new download in the frontend they got an error screen after saving the download (screenshot added). When an user in the user group Super User tries to add a new download in the frontend everything works just fine.

Running PHP 7.4: The above works fine, but a white screen is given when I go to the Jdownloads options in the backend.

Can you please help me to solve the displayed error while adding a new download in the frontend? PHP 8.0

Thanks in advance, Sien



edit: displayed in error.log: PHP Warning:  Undefined array key "name" in ......../administrator/components/com_jdownloads/tables/download.php on line 101

edit:

I've found the trigger for the errormessage. Creating a new download in the frontend give the error messgae when I uncheck this option at the related user group (Registrered) .

I've created a workaround for my site for now to hide this item with my custom.css, but a better solution would be to solve the bug in a futere version of JDownloads.

Thanks.

Hi,
excuse me for the delay.
I will try to check this issue during the day and i will post afterwards here a fix.

Hi
I have tested on a site with PHP 8.0.11,  Joomla! 3.10.0 and jD 3.9.8.1 but had no problem when I created a Download in the Front End with a Registered User.
The  same code is also used when editing a Download in the front end

I also added some diagnostic code to check that $thumb_image_files is an arrary.
Also tried adding multiple images.
It may perhaps depend on some other settings.  More info would be appreciated

Thanks Colin. I can confirm this result also by me. So we need maybe more settings from jDownloads options.

Sien,

I have sent you a PM explaining how to get details of your jD options setup to send to us so we can better replicate your setup
Best wishesColin

Sien
Please canyou try Test 3
Please rename the exising download.php in
<your site>\administrator\components\com_jdownloads\tables\as say download-saved.php so it can be reset if neither test is sucessful.

Unzip the attached to get download-test3.php

Then add download-test3.php and rename it to download.php - then see if the that solves the problem.
If this does not solve the problem then I will need to have full super user access to your site to progress further

Hi Sien,
I could now reproduce your problem. For this it is required to disable the view 'Images' option for the 'Registered' Usergroup in the jDownloads User Group Settings. See pic.

It is a simple bug and affects all PHP versions, not only PHP 8.

Attached a fixed version.
Please copy the unzipped file to this folder: /administrator/components/com_jdownloads/tables/ and overwrite the older file. Please test then again to create a new Download in the frontend as registered user and post here your result.
Thanks a lot.
