Add Custom Settings

A useful feature of the Debug Toolbar (EEDT) is that you can integrate your Panel's, or custom extension's, settings into the EEDT settings mechanism. Doing this has a couple advantages:

Note: this tutorial assumes you're already familiar with EEDT extension development and have read Creating custom debug panels

1. All settings are consolidated under one Settings Form (the EEDT one)
2. Developers don't have to bother creating their own custom Settings Forms for their debug add-ons.
3. Users have automatic access override config options for your add-ons once installed.

Doing this requires 2 hooks be used in order to, first, register your settings with the EEDT settings object and, second, to create the form elements for updating.

A good point of reference for this tutorial would be the Performance Alerts extension that comes bundled

The Extensions

You'll have to create 2 Extensions for your EEDT Add-on

ee_debug_toolbar_init_settings

This hook is to tell EEDT what your settings are and what values to use by default:

Be sure to always check for ee()->extensions->last_call like in the below to ensure you get all the other set settings.

namespace DebugToolbar\MemoryHistory\Extensions;

class EeDebugToolbarInitSettings extends AbstractHook
{
    /**
     * @var array|string[]
     */
    protected array $default_settings = [
        'memory_history_position' => "top right",
    ];

    /**
     * @param array $default_settings
     * @return array
     */
    public function process(array $default_settings): array
    {
        $default_settings = (ee()->extensions->last_call != '' ? ee()->extensions->last_call : $default_settings);
        return array_merge($default_settings, $this->default_settings);
    }
}
