Upload Photo2:
I want to display the thumbnail of the user. Any ideas how to go about it?
Thanks,
Actually, you need to store path to the image and point to that path in img src attribute. Store images for example in webroot.images directory.
Can u plz suggest how to go about it. I tried all the tuts but was unable to get the desired result.
Thanks,
What is stored in your database? If it is the URL of the image (assuming the field is named photo2):
<?php echo CHtml::image($model->photo2); ?>
If is the image it self… then you need to be trickier… you will have to call a controller’s action and push the mime type and the contents of the field
// on your view
<?php echo CHtml::image($this->createUrl('controller/action',array('id'=>$model->id)); ?>
// on the controller's action
$id = Yii::app()->request->getParam('id');
$model = MyModel::model()->findByPk($id);
// whatever the type of the image is
header('content-type: image/jpeg');
// whatever the field name is
echo $model->photo2;
Thanks the photo is displayed but can u plz suggest how to resize it and display the same as the thumbnail.
Thanks,
Take a look at this topic http://www.yiiframework.com/forum/index.php?/topic/24475-generating-thumbnail-of-image-and-using-it/page__p__118585__fromsearch__1#entry118585
I do not know if you wish to thumbnail display or to create a thumbnail of the picture… here both ways:

Hi,
I want to display the thumbnail of the uploaded image. I have used the image helper yii extension and given write permission to the images folder under protected. I am getting the following errors.

1064 if ($this->isDataStream === true)
1065 {
1066 $this->format = ‘STRING’;
1067 return;
1068 }

1071
1072 // non-image files will return false
1073 if ($formatInfo === false)

1078 }
1079 else
1080 {

Any ideas plzzzz.

Are you sure you have permissions set? make sure is read+write and that the path is the correct one
I finally can avoid too much PHP just for an <img>.
As my test upload form was for the current user avatar, i have that in my controller
<?php
class UploadController extends Controller
{
function actionIndex()
{
$dir = Yii::getPathOfAlias('webroot.uploads');
$uploaded = false;
$model=new Upload();
if(isset($_POST['Upload']))
{
$curentuser = Yii::app()->user->name;
$model->attributes=$_POST['Upload'];
$file=CUploadedFile::getInstance($model,'file');
if($model->validate()){
$uploaded = $file->saveAs($dir.'/'.$curentuser.'_avatar.jpg');
}
}
$this->render('index', array(
'model' => $model,
'uploaded' => $uploaded,
'dir' => $dir,
));
}
}
So i can display the image in the view with just
<img src="http://localhost/blog/uploads/<?php echo Yii::app()->user->name; ?>_avatar.jpg" />
That’s really basic usage but it’s a start point.
