Panels: custom style plugin

Panels style plugins are made for wrapping panel panes and panel regions into extra markup. 99% of your needs are covered by a "Panels Extra Styles" module. Please look at that module if you need extra styles for panels. But if you need some specific style you can easily implement it.

Ctools: custom relationships plugin

Relationships plugins are "bridge" between existing context (that is already set up in a panel) and a context which you want to get from existing one. Let's say your panel contains "Node" context and you want to get a node author (user from node:uid property). To do that you can just set up "Node author" relationship in a panel (under a "contexts" tab) and that's all. That's why relationships plugins are so important - they provide easy way for getting context from existing contexts. Please have a look at this post before continue reading - there is described how to create module integrated with ctools API which allows us to define own plugins.

Ctools: custom argument plugin

This time we will consider an argument plugin. Arguments are pretty similar to contexts. Actually arguments are context objects loaded from url. By default ctools provides a full set of needed arguments such as "Node: ID", "User: ID", "User: name" etc. But what if you've created a custom context? You might need to create a custom argument for your context (if you want to use your context as an argument of course). I advise you to read previous articles from "Ctools custom plugin" series such as "Ctools: custom access plugin" and "Ctools: custom context plugin". It's also required to read "Ctools: custom content type plugin" before reading this post because there I've described how to create a module integrated with ctools API which can contain ctools plugins.

Ctools: custom context plugin

In previous post we created an access ctools plugin which can be used as a selection or visibility rule in panels. It's time to learn how to create another important custom plugin - a context. It provides additional information for a panel page. For example if you've put a node context to the page you will be able to use node properties as substitutions for a page title. Moreover you will be able to put node fields as panes to a page. By default ctools module provides useful contexts (node, user, taxonomy_term, entity etc) but you can define your own. Please, read first post of "Ctools custom plugins" series before continue reading this. There we've created a module integrated with ctools.

Ctools: custom access plugin

Last time we've learned how to create custom ctools content type plugin. In that post we've already created a module example_module where we defined the plugin. This time we will learn how to create custom ctools access plugin. This type of ctools plugins can be used as a selection rule for a panel variant or as a visibility rule for a panel pane. Please, read previous post before continue reading this. There is described how to create a module and integrate it with ctools.
