#15906 new defect (bug)

validate_plugin needs all_plugins filter

If a plugin adds plugins to the plugin list in the plugin admin screens using the all_plugins filter, the added plugins will not validate. If the all_plugins filter is added to the validate function, then the plugin validates and activates fine.

get_plugins() function is used in several more places (e.g. in Plugin Editor). Shouldn't we use all_plugins filter in get_plugins() itself?

#2 @wpmuguru

If it was added to get_plugins, then both the $plugin_folder parameter & context (ex. plugin_editor) should be provided to the filter. So, I'm not sure that moving the filter there would provide any benefit.

We killed off the all_plugins filters in 3.0, I believe.

I was thinking of active_plugins: [12947].

I'm good with punting this one to 3.2.

Patch still valid. @dd32 did you want to re-evaluate this?

I just stumbled over this one. Adding a plugin via all_plugins can't be activated, because validate_plugin() doesn't know the plugin.

The filter was moved to core in [12722], but was originally requested in The reporter wanted to have the filter in `get_plugins()`, but it got added to the list table instead, see

Adding the filter to get_plugins() itself would be tricky because it already does plenty of work and also caching. I think adding the filter to each get_plugins() call where it could make sense should be harmless. In this case it's only validate_plugin() because I don't think that the plugin editor and the upgrade/install process are quite useful for custom plugins.

My current code is:

add_filter( 'all_plugins', function( $plugins ) {
        $_gp_plugins = get_plugins( '/gp-plugins' );  // WP_PLUGIN_DIR . '/gp-plugins'

        // Fix plugin file path
        $gp_plugins = array();
        foreach ( $_gp_plugins as $file => $data ) {
                $gp_plugins[ 'gp-plugins/' . $file ] = $data;

        $plugins = array_merge( $plugins, $gp_plugins );
        unset( $_gp_plugins );

        return $plugins;
} );
