The plugins have been updated. Please go to

  Tools --> Update --> Tab "Plugins"

You should see available updates for plugins. Updating the plugins before upgrading to 15.0.0 is recommended.

This worked for me.

For your information, for Piwigo 15, the minimum technical version of PHP is 7.1 (and we just discovered a bug with PHP 7.2, that we're going to fix) but the minimum version we ask users to have is 7.4. We will certainly increase it to 8 for Piwigo 16.

Thank you for the heads up. In fact using 7.1 right now.


Is this a new feature in P15 that opening any gallery I get some new button "Search in this set" which ends up with error message:

Fatal error: Uncaught Error: Call to undefined function array_key_first() in /var/www/html/galerii/include/functions_search.inc.php:717 Stack trace: #0 /var/www/html/galerii/include/functions_search.inc.php(2016): get_regular_search_results(Array, '') #1 /var/www/html/galerii/include/section_init.inc.php(364): get_search_results('psk-20241108-rq...', NULL) #2 /var/www/html/galerii/index.php(12): include('/var/www/html/g...') #3 {main} thrown in /var/www/html/galerii/include/functions_search.inc.php on line 717

Luckily I can disable it in Configuration > Options > Display > Main Page >  [  ] Activate button "Search in this set";
[  ] Activate icon "Search in this set".

Seems to be function added to PHP 7.3+, which I don't have. If I wanted to add given function at https://www.php.net/manual/en/function. … -first.php "Notes" part as temporary workaround, where would be the best place to put it? ( I don't think just before line 717 in functions_search.inc.php would be best place, as this function might be used elsewhere in the code also ) Or better yet could you please add it to Piwigo 15.1 or something? :-)

Just because you can use PHP 7.4 it doesn't mean you should.

It's a problem we no longer have in PHP8+, and as you said, the minimum version for Piwigo is PHP 7.4, so the problem will be solved for Piwigo 15.1.0

Thank you.

To add a little context, this way of adding a comma like this is because for commits on github it's much cleaner, you can see an example here : https://spatie.be/courses/front-line-ph … efinitions

Just because you can (in PHP 8+), doesn't mean you should, while it breaks backwards compatibility.
Just for aesthetics (and not even the code itself, which looks now more ugly IMHO and longer (with extra unnecessary commas)... just git commits are slimmer) and zero functional benefit. Right? ;-)

Are you still using PHP 7?

yes. as it's still written on minimum requirements page.

119 $selected_category_name = get_cat_display_name_from_id(

121 );

removed the comma on line 120:

119 $selected_category_name = get_cat_display_name_from_id(
120   $selected_category
121 );

and it works now without error.

I was just beginning to look for an easier solution to storing and viewing pdf's... and voila! Version 15 was released! Woo Hoo for me! Thanks!
