Problem with model and image upload

Archives Yii 1.0.x Discussions
1

I have a model with the following rules:

public function rules()


{


	return array(


		array('strTitle','length','max'=>255),


		array('strUrl','length','max'=>255),


		array('strImage', 'file', 'types'=>'jpg, gif, png'),


		array('strTitle, strText', 'required'),


		array('booPublish', 'numerical', 'integerOnly'=>true),


	);


}

no I have the problem that the create action works perfectly. But when I want to edit some values of an existing entry (but don't want to upload a new image), I always gets an error which says that "strImage" cannot be blank.

How can I keep the existing image, without error message?

for the strImage rule, set the 'on' option to be 'insert'.

Ok, I've done this, but when I now edit a record and save it, strImage is empty (and i couldn't upload any image) :frowning:

What I want to do, is to keep any existing image (without error message when editing a record), until the user decides to upload a new image for an existing record.

Did you call $model->strImage=CUploadedFile::getInstance(…)?

Yes, I've created a BaseModel and extended my model from it:

class BaseModel extends CActiveRecord

{

  public function afterSave()

  {

    $strDir = Yii::getPathOfAlias('webroot').DIRECTORY_SEPARATOR.'data'.DIRECTORY_SEPARATOR.strtolower($this->tableName()).DIRECTORY_SEPARATOR;

    if ($this->hasAttribute('strImage'))

    {

  $objFile = CUploadedFile::getInstance($this, 'strImage');

  if ($objFile->getError() == 0)

  {

    $this->strImage = $objFile;

    $this->strImage->saveAs($strDir.$this->strImage);

  }

    }

  }

}

I don't think adding 'on' option would cause the problem you described. You are merely disabling a validation rule. It won't affect whether or not 'strImage' is empty.

Ok, no I got it working without any errors:

  public function beforeValidate()

  {

    if ($this->hasAttribute('strImage'))

    {

  $objFile = CUploadedFile::getInstance($this, 'strImage');

  if ($objFile->getError() == 0 && $objFile->getSize() > 0)

  {

    $this->strImage = $objFile;

    return $this->strImage->saveAs($this->getImageDir().$this->strImage);

  }

    }

    return true;

  }

but I've got stil the problem that in case of editing a record, the attribute for strImage is set empty.

I think there must be a hidden field for holding the value for any previously uploaded image, right?

No, there's no such hidden field to store existing file upload.
