Multisite - Plugin only activated on single Site

[danielbarenkamp]

Hi there,

Env: multisite

When a plugin is ONLY activated in one subsite, but not network wide, it does not show the update. Is there any workaround for this?

As far as I know, the only viable workaround would be to make a new plugin that just runs the update checker, then activate that plugin either network wide or at least on the main network site.

That would be a solution! We got a Framework plugin activated in multisite. But how can we run each plugins updater? Is there a function to add more than 1 update URL? Or can we return more update JSON files? Maybe you got a short example?

You can just create multiple instances of the update checker and give each instance a different update URL and plugin file name / slug.

For example, if you normally initialise the update checker like this:

$myUpdateChecker = Puc_v4_Factory::buildUpdateChecker(
    'http://example.com/path/to/plugin1.json',
    __FILE__,
    'plugin1'
);

You could rewrite it not to rely on the __FILE__ constant and then have multiple similar blocks of code in one file:

$myUpdateChecker1 = Puc_v4_Factory::buildUpdateChecker(
    'http://example.com/path/to/plugin1.json',
    $pathToPlugin1,
    'plugin1'
);

$myUpdateChecker2 = Puc_v4_Factory::buildUpdateChecker(
    'http://example.com/path/to/plugin2.json',
    $pathToPlugin2,
    'plugin2'
);

Finding the correct plugin file name could be slightly complicated. If you don't need a perfect solution, you could probably just hardcode the directory name and PHP file name: $pathToPlugin1 = dirname(__DIR__) . '/plugin1/main-file.php
