With plugins playing such a large role in Hotaru CMS, it's important that they play nicely with each other. If your plugin relies on other plugins to function, specify them with "requires: " in the comments section at the top of your plugin file. E.g: Code: <?php /** * name: Example plugin * description: Doesn't do anything * version: 0.1 * folder: example * class: ExamplePlugin [B][COLOR=Red] * requires: submit 0.1, users 0.1[/COLOR][/B] * hooks: install_plugin, theme_index_top */ Important! The "requires: " line should be a comma-separated list of plugin_folder *space* plugin_version pairs. If your plugin doesn't require any other plugins, don't include "requires: ". An empty "requires: " will generate an error.
