  • I would like to write a plugin or snippet to:
    1. create 3 tabs for the top hierarchy documents (which are language docs: en, de, ru)
    2. Add those as tabs to each document edit.
    3. Result should be:

    General | Settings | EN | DE | RU

    4. We use the same alias for each language, so we can link the langauges directly to each other. E.g. en/news and ru/news

    How to achieve this goal in Modx Evolution?

    This question has been answered by breezer. See the first response.

    • Yes it is possible, you'll use the OnDocFormRender and OnDocFormSave events with a plugin. I'm not at my computer with all my sample code till late tonight but when I get a chance I'll post some code to get you started.

        Heres a plugin demo which should help you get started. I usually put the code in a file and link to it in the plugin content, easier to edit in my opinion. Name your plugin whatever you want, and either link to the file location, or add the code below to the plugin content.

        // if including a file
        include MODX_BASE_PATH.'assets/plugins/tabs/tab.plugin.php';

        /*  tabs.plugin.php
        Copy / paste the following into the SQL tab in phpMyAdmin
        to create the sample table
        Change the {PREFIX} part to match your setup
        CREATE TABLE IF NOT EXISTS `{PREFIX}tabs_demo` (
          `id` int(10) NOT NULL auto_increment,
          `name` varchar(50) NOT NULL default '',
          `docid` integer NOT NULL DEFAULT '0' COMMENT '',
          `content` mediumtext,
          PRIMARY KEY  (`id`)
        // name of the table which holds your data, without any prefix
        $table_name ='tabs_demo';
        $tab_tpl ='
