yii1.1: kann einen Datensatz nicht aktualisieren, ohne eine Umlage zu laden

Question

Ich habe versucht, mit einer Website umzugehen, die von einem anderen Programmierer geschrieben wurde. Die Website ist mit yii 1.1.4

gebaut Es scheint, dass ich einen "Speicher" Datensatz nicht aktualisieren kann, ohne jedes Mal ein neues Bild hochzuladen. Hier ist die Meldung, die ich erhalte, wenn ich versuche, ein Update durchzuführen, ohne ein Bild hochzuladen: "Bitte korrigieren Sie die folgenden Eingabefehler:

Bild kann nicht leer sein."

das Bildfeld (aka "icon_filename") ist nicht einmal erforderlich. auch, die meisten Datensätze haben noch kein Bild hochgeladen.

jemand weiß, was ist das Problem?

hier ist der Code:

Modelle:

public function rules() { 
    // NOTE: you should only define rules for those attributes that 
    // will receive user inputs. 
    return array(
     array('name, stream_id, full_address,about, country_id', 'required', 'on' => array('create')), 
     array('status, stream_id, lock_version', 'numerical', 'integerOnly' => true), 
     array('name, email', 'length', 'max' => 255), 
     array('about, full_address, website_url', 'length', 'max' => 500), 
     array('website_url, maps_service_url', 'url'), 
     array('phone, fax', 'length', 'max' => 30), 
     array('phone, fax', 'PcSimplePhoneValidator'), 
     array('country_id, region_id, assigned_user, created_by, last_updated_by_user_id', 'length', 'max' => 10), 
     array('assigned_user', 'validateAssignedUser', 'except' => 'search'), 
     array('city_id', 'length', 'max' => 6), 
     array('icon_filename', 'file', 
      'types' => "jpg,jpeg", 
      'wrongType' => Yii::t('StoresModule.forms', "Invalid file type. These are the supported file types: {extensions}"), 
      'maxSize' => 1048576, 
     ), 
     array('icon_filename', 'file', 'allowEmpty' =>true, 'on' => 'update'), 
     array('updated_on', 'safe'), 
     // The following rule is used by search(). 
     // Please remove those attributes that should not be searched. 
     array('id, name, email, stream_id, searchText, status, about, full_address, phone, fax, website_url, country_id, region_id, city_id, icon_filename, assigned_user', 'safe', 'on' => 'search'), 
    ); 
} 

Controller:

Answer 1

sein Sie können verschiedene Attribute getInstance und Speicher in DB verwenden müssen?

E.G.

public $photo; 

    array('photo', 'file', 'maxSize' => 1048576, 'types' => 'jpg, png, gif, jpeg', 'allowEmpty' => true) 

in Controller

$model->photo = CUploadedFile::getInstance($model, 'photo'); 

dann Name, Pfad speichern, oder was Ihr wünschen

$model->pictureName = $model->photo->name;
