Extension plugins

While WP ISPConfig 3 supports Gutenberg Blocks it may be necessary to add additional fields or functions.

If a field is not (yet) provided or is missing an important option, check out the supported action/filter hooks to customize it.

When a more advanced solution is required, building up a small Wordpress plugin and extend the IspconfigAbstract can be helpful. This allows control over all the ISPConfig REST API and enables a quick access to it using [YourClass] shortcodes

Check out the below shortcode example of [IspconfigShowTemplates]

/**
 * Plugin Name: WP-ISPConfig3 Show Templates Example
 * Description: Example plugin to display all available ISPConfig3 client templates using shortcode [IspconfigShowTemplates]
 * Version: 1.0.0
 * Author: ole1986 <ole.k@web.de>
 * Author URI: https://github.com/ole1986/wp-ispconfig3
 */
require_once ABSPATH . '/wp-content/plugins/wp-ispconfig3/ispconfig-abstract.php';

class IspconfigShowTemplates extends IspconfigAbstract
{
    public function Display($attr, $content = null)
    {
        // connect to ispconfig3 through REST API
        $this->withSoap();
        // fetch all available client templates
        $templates = $this->GetClientTemplates();
        // output only the names
        $templateNames = array_map(function ($item) {
            return $item['template_name'];
        }, $templates);

        echo implode('<br />', $templateNames);
    }
}

new IspconfigShowTemplates();

The next lines is a more complex example of a registration form using the shortcode [IspconfigRegisterClient]

<?php
/**
