YII file upload not adding to database using form - php

Question

Im attempting to add a file upload field to a form in YII, while its succesfully submitting and uploading the file to the correct folder, its not adding anything to the database.
Im only learning this platform so any guidance would be great.
Here is my view...
<div class="row">
<div class="span4"><?php echo $form->labelEx($model,'slider_image'); ?></div>
<div class="span5"><?php echo $form->fileField($model,'slider_image'); ?></div>
<div class="span3"><?php echo $form->error($model,'slider_image'); ?></div>
</div>
Here is my controller...
public function actionEdit() {
$id = Yii::app()->getRequest()->getQuery('id');
$model = CustomPage::model()->findByPk($id);
if (!($model instanceof CustomPage)) {
Yii::app()->user->setFlash('error',"Invalid Custom Page");
$this->redirect($this->createUrl("custompage/index"));
}
if(isset($_POST['CustomPage'])) {
$model->attributes = $_POST['CustomPage'];
$model->image=CUploadedFile::getInstance($model,'slider_image');
if ($model->validate()) {
if ($model->deleteMe) {
$model->delete();
Yii::app()->user->setFlash('info',"Custom page has been deleted");
$this->redirect($this->createUrl("custompage/index"));
} else {
$model->request_url = _xls_seo_url($model->title);
if (!$model->save()) {
Yii::app()->user->setFlash('error',print_r($model->getErrors(),true));
} else {
$model->image->saveAs(Yii::app()->baseUrl.'images/'.$model->image);
Yii::app()->user->setFlash('success',
Yii::t('admin','Custom page updated on {time}.',array('{time}'=>date("d F, Y h:i:sa"))));
$this->beforeAction('edit'); //In case we renamed one and we want to update menu
}
}
}
}
}
and my model
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
// other rules
array('slider_image', 'file', 'types'=>'jpg, gif, png'),
);
}
The form itself overall is working fine, unfortunately I dont understand how YII adds to the database
Thanks

EDIT: Ive also obviously got a slider_image field in that table

Answer 1

What your Controller code would do is save the file name of the upoloaded file in your database table. Another thing is: your code:
$model->image=CUploadedFile::getInstance($model,'slider_image');
is referring to the wrong attribute. I think it should be:
$model->slider_image=CUploadedFile::getInstance($model,'slider_image');
Finally, you need to call $model->slider_image->save('path.to.file'); in order to save the file to disk

Answer 2

I believe you get stock at $model->validate(). Because you do copy image above this line copying is fine but you do not go through validation so it never saves to DB.
var_dump($model->validate()); to see what is going on...
