XF 2.1 How to extend AbstractOption

[shqawe]

I'm trying to extend AbstractOption class to render thread_prefix in my addon options and this is my code:

class Prefix extends XFCP_AbstractOption
{

public static function renderSelect(\XF\Entity\Option $option, array $htmlParams)
    {
        $data = self::getSelectData($option, $htmlParams);

        return self::getTemplater()->formSelectRow(
            $data['controlOptions'], $data['choices'], $data['rowOptions']
        );
    }
   

    protected static function getSelectData(\XF\Entity\Option $option, array $htmlParams)
    {
        /** @var \XF\Repository\AbstractPrefix $prefixRepo */
        $prefixRepo = \XF::repository('XF:AbstractPrefix');

        $choices = $prefixRepo->getClassIdentifier()->getPrefixListData();
        $choices = array_map(function($v) {
            $v['label'] = \XF::escapeString($v['label']);
            return $v;
        }, $choices);

        return [
            'choices' => $choices,
            'controlOptions' => self::getControlOptions($option, $htmlParams),
            'rowOptions' => self::getRowOptions($option, $htmlParams)
        ];
    }
}

but i got this error:

XF\Option\XFCP_AbstractOption' not found

and when i change the extend to this

class Prefix extends \XF\Option\AbstractOption

i got this error:

An exception occurred: [Error] Cannot instantiate abstract class XF\Repository\AbstractPrefix in src\XF\Mvc\Entity\Manager.php on line 261

and line 12 in Prefix.php is this $data = self::getSelectData($option, $htmlParams);

can someone help me in this issue?

It's an abstract (base) class, so it should extend the class directly to create a new concrete class. You shouldn't be using the class extension system, which is only for extending concrete classes.

@Jeremy P Do mean class should to be class Prefix? if not can you tell me how should i do it

 

[Jeremy P]

<?php

namespace myAddons\Option;

class Prefix extends \XF\Option\AbstractOption
{
    // ...
}

 

[shqawe]

@Jeremy P i did that before as i mentioned above but it doesn't work

Ah, I see:

$prefixRepo = \XF::repository('XF:AbstractPrefix')

You can't instantiate the repository XF:AbstractPrefix because it's not a concrete class. You'd have to instantiate something that subclasses it.
