HumHub - Putting People and Pieces together

Test Status Yii2 CLA assistant

HumHub is an intuitive to use and modular designed open-source software, used primarily as social network, knowledge database, intranet or information and communication platform.

The software is written in PHP and is best described by dividing into 4 main parts: User, Spaces, Content and Modules.

  • User: All users have their own customisable profile (including name, profile picture, cover photo and personal information) and can follow and interact with each other. If wished and enabled, users can create own content, comment posts and join Spaces. Profile fields, permissions and all settings can be defined individually by the network operator (administrator).

  • Spaces: Rooms or groups for any projects, departments, events or other needs. Network operators can create as many Spaces as needed and automatically map users into the desired Spaces. HumHub comes with an advanced permission and notification system (including email summaries).

  • Content: Users can create content of all kinds (posts, wiki pages, photo/video, schedule appointments, create events or tasks) depending on their permission and share it with other members in their Space. There is a multi-level comment function, versatile collaboration options and also features to report inappropriate posts and content. All Content, Spaces and Members can be easily found through various and individually definable filter and search functions, Content can be edited, deleted and archived.

  • Modules: The main software is designed in a modular way and can be extended by approximately 80 modules. These can easily be added to by installation and activation. This gives operators the possibility to set up and configure the network according to their needs and individual wishes. Among the modules are Advanced LDAP, RESTful API, Mass User Import, Calendar, Wiki, OnlyOffice, JWT SSO, Legal Tools, Translation Manager, Custom Themes and Custom Pages, Tasks, Gallery, News, Polls and Mail for Direct Messages.

With HumHub, we help people around the world to connect, stay informed, display and share content of various kinds, exchange files and communicate and collaborate with each other.

The software is responsive designed and works great on different devices, including smartphones and tablets. HumHub is available in over 30 languages and is used in over 4,500 organizations worldwide.

linkpreview-issues's Issues

Error with PHP 8.1 and error_reporting(E_ALL)

If error_reporting is set to E_ALL, the previewing doesn't work.
I didn't take time to investigate. Perhaps a composer update would solve the problem, the the composer.json is not present, so I cannot test.

Error log:

The bug is here:

As $info->image can be null.

Incorrect link preview for non-UTF-8 sites

For example, if I want to share a page encoded in "Windows-1250", the title and description of the preview will end with the first Latin extended character.

Can this somehow be corrected/converted?

Title should be "ANKETA: Jak vnímáte poslední kroky Ubisoftu?"

Preview on peertube video

Hi,
Would it be possible to find a way to have a preview on a peertube video link, with the LinkPreview plugin?
Then, this great opensource social platform would be supporting an opensource video platform :)
Thanks!

[Future Request] REST API

It is more wonderful if a link preview was automatically created in conjunction with the post creation API, or linked to the post with the link preview API.

Favicon is replaced by new one when posting a link

Hi there.
When adding a link in a post, the preview works well, but the favicon is changed by the favicon of the linked website.
That's not a big deal but it's disturbing seeing the youtube favicon instead of the good one.

Thanks for your help.

Remove 'error' text on internal links

When I link to other internal links on my humhub instance it displays 'error' in the link preview

error

I understand that these can't be rendered completely, but could we remove the word 'Error' from the preview?

Problem accepting payment

Hello! Attempting to install this module, 'without account' and as 'Individual (private user)', I found that card is really the only relevant option from here in Norway. Having tried three different cards, now, two credit cards and one debit card, all three attempts resulted in a 'declined' message.

This was suprising because all three cards have more than enough money on them, and are set up to be possible to use for purchases online. The experience was unusual, as it is not uncommon for me to buy things online. Unless this is something very particular that just relates to me, you may want to contact Stripe to see if there is some technical problem that prevents people who do not have iDEAL, SEPA Direct, Alipay, SOFORT, giropay or EPS, from buying this module. Thanks

issue with encoding

As a french user, there are a lot of links to french websites.

Preview appears like this (minus the space ... otherwise github translate the accent correctly)

Un hommage au pilote l&eacute ;gendaire Ayrton Senna

instead of

Un hommage au pilote légendaire Ayrton Senna

All accent and special chars are incorrect.

I guess it's a UTF-8 encoding issue...

Problems with à or è chars

Seems there are problems with links with accented letters like: ò,à,è and son on.

In paritcular when embedding links from linkedin.
Same links in the past used to works .

Add link preview contents to search index

Would it be possible to add the link preview title and description to the search index so that the content the link is attached to can be found through those keywords?

Doesn't works on mobile.

It works great from my computer but it doesn't do anything from a mobile.

Would you please do something for that.
Thanks

Bad description in case using youtube

Dear all

could you help pls?

Not working as expected

I've recently installed the linkpreview module v1.15.3. I'm running HH v1.8.2 community edition on a hosted server.

Initially the module worked reasonably well (the thumbnail was a bit small). After a few days it now seems to work only sporadically.

Some sites produce no link at all: https://bbc.co.uk https://twitter.com/

Some sites generate a text preview, but no image: https://www.google.co.uk/ https://www.amazon.co.uk/

And some sites generate a thumbnail and text, as expected: https://www.independent.co.uk/ https://www.humhub.com/en

I've tried including other text in the post, before or after the link.

Any ideas?

Preview Image size

Is there a way to enlarge the image in the preview, is it module-based or humhub core-based of how the previews are displayed?

LinkPreview was working great and then just stopped working

We are running an older version of HumHub and have been using LinkPreview with great success for the better part of a year. All of a sudden, LinkPreview just stopped working. We haven't upgraded anything (OS, LinkPreview, HumHub, etc). There is plenty of disk space free and no RAM issues.

None of the logs have any useful information and the specific 500 error doesn't seem to be recorded anywhere (/var/log/httpd/* or in HumHub admin logs).

Do you have any suggestions for what we might do to regain this functionality? Any other information that I could provide?

Thanks,
Bill

Link previews with validation errors are silently discarded

If a link preview record fails validation, for example because a URL is longer than 255 characters, the preview is silently discarded upon submitting the post.

This can be especially bewildering if the troublesome URL is for the preview image, over which the user has no control.

Alert box showing "asdf"

After adding a comment to a global content and submitting a form containing this comment, I got an alert box:
image

Isn't it a forgotten test in humhub.linkpreview.js?

        this.$.closest('form').on('submit', function () {
            alert('asdf');
        });

Bought this. Does not work

Is there an issue with the add-on we should be aware? My installaton of humhub does not produce previews in any link. Are there dependencies that should be taken care of before installation?

Preview relative image links broken

When the preview image is a relative link, it resolves incorrectly to a URL on the HumHub site, rather than on the target site, causing the preview image to fail to load.
