如何在Elgg中上传图像

Question

我一直试图在Elgg 3.x中保存一个Elgg 实体图标，但没有成功。myObject保存到数据库中，但是文件不会上传。

我做错了什么？

先谢谢大家。

save.php form

<?php
    echo elgg_view('input/file', [
        'name' => 'upload[]',
        'multiple' => true,
        'label' => 'picTuREs',
    ]);
?>  

save.php动作文件

foreach (elgg_get_uploaded_files('upload') as $upload)
{
    $myObject = new ElggObject();
    $myObject->subtype = "my_object";
    $myObject->access_id = ACCESS_PUBLIC;

    $myObject->saveIconFromUploadedFile($upload);

    $myObject->save();
}

更新您在以下方面的行动：

$upload_guids = (array) get_input('uploads');

if (empty($upload_guids)) {
    return elgg_error_response(elgg_echo('file:error:empty_form'));
}

foreach ($upload_guids as $upload_guid) {
    $file = new \ElggFile();
    
    $file->title = $title;
    $file->description = $description;
    $file->access_id = $access_id;
    $file->container_guid = $container_guid;
    $file->tags = string_to_tag_array($tags);

    $file->save();
    
    if ($file->getSimpleType() === 'image') {
        $file->saveIconFromElggFile($file);
    }
} 

如果使用自定义子类型，则应该通过这个对象扩展\ElggFile，如下所示：

class MyCustomFile extends \ElggFile {
    
    const SUBTYPE = 'my_subtype';
    
    protected function initializeAttributes() {
        parent::initializeAttributes();

        $this->attributes['subtype'] = self::SUBTYPE;
    }
    
    /**
     * @see ElggEntity::saveIconFromElggFile()
     */
    public function saveIconFromElggFile(\ElggFile $file, $type = 'icon', array $coords = array()) {
        return false;
    }
}
