Hello
i am new in Yii development
i made a model for the users and its working very fine but i want to make the user upload his photo and i show it in the view
i made "BLOB" field in my database for the photo
how can i save it in the db ? and how to show it in the view ? and what i need to change in the controll?
Thanks,
Yasser Hossam
Maybe instead of a blob field, you could use a varchar(). In the upload process just save the file to a directory like ‘images/avatars’. Then in the display just set an <img/> tag with the image.
I have seen info on the various sites about how to store an image in a blob field, but I have did it.
Hi YasserHossam,
see the discussion.
Thank you very much jkofsky ,Alexandre Rodichevski
raelly helped me alot.
now i can upload the photo and it uploaded to the directory and with the name wich i specified .
but i can’t show it in the view.php or _view.php
i made a lot of effort to try that but i feel there is some problem , the image not appear in any case
some of code wich i used
<?php echo CHtml::image(Yii::getPathOfAlias(‘webroot’).’/protected/UsersPhotos/’.$model->Photo); ?>
<?php echo CHtml::image(dirname(Yii::app()->getBasePath()).DIRECTORY_SEPARATOR.‘protected’.DIRECTORY_SEPARATOR.‘UsersPhotos’.DIRECTORY_SEPARATOR.‘defualt.jpg’, ‘DORE’); ?>
<?php
echo "<img src=\"";
echo CHtml::encode('..\..\UsersPhotos/'.$model->Photo);
echo "\" alt=\"image\" height=\"200\" width=\"20\"/></img>";
?>
<?php echo CHtml::image(dirname(Yii::app()->getBasePath()).DIRECTORY_SEPARATOR.‘protected’.DIRECTORY_SEPARATOR.‘UsersPhotos’.DIRECTORY_SEPARATOR.‘defualt.jpg’, ‘DORE’); ?>
Note: i am sure that it is the right path but the image not displayed in any of them !
and i made html file and put img tag with the same path and it desplayed normally
please advide me .
Thanks,

Going to plug my own extension here and suggest you try Yush - http://www.yiiframework.com/extension/yush/
If you post your controller and model code, I’ll be happy to assist you to get it working.
Thanks,

Hello Matt,
Really thank you .
i don’t know the matter need to use extension or not . i just need to make the image appear like in html .
here is my controller creation function
public function actionCreate()
{
$model=new Users;
if(isset($_POST['Users']))
{
$model->attributes=$_POST['Users'];
$UserName=$model->UserName;
$uploadedFile=CUploadedFile::getInstance($model,'Photo');
$fileName = "{$UserName}_{$uploadedFile}";
$model->Photo = $fileName;
if($model->save())
{
$uploadedFile->saveAs(Yii::getPathOfAlias('webroot').'/protected/UsersPhotos/'.$fileName); // image
// redirect to success page
$this->redirect(array('view','id'=>$model->UserID));
}
}
$this->render('create',array(
'model'=>$model,
));
}
my view :
<b><?php echo CHtml::encode($model->getAttributeLabel('Photo')); ?>:</b>
<?php echo CHtml::encode (dirname(Yii::app()->getBasePath()).DIRECTORY_SEPARATOR.'protected'.DIRECTORY_SEPARATOR.'UsersPhotos'.DIRECTORY_SEPARATOR.'defualt.jpg', 'DORE'); //show the path ?>
<?php
echo "<img src=\"";
echo CHtml::encode('..\..\UsersPhotos/'.$model->Photo);
echo "\" alt=\"image\" height=\"200\" width=\"20\"/></img>";
?>
thanks again
if you want to show the image on view file
for e.g
1) in _form.php you can write a
'htmlOptions'=>array('enctype' => 'multipart/form-data');
2) In your controller image filed save on db
$model->image = CUploadedFile::getInstance($model, 'BLOB');
$model->image->saveAs('upload/coupon/'.$model->BLOB);
3)
Display the image on _form.php file
<?php
$baseUrl = Yii::app()->baseUrl;
$img = $baseUrl.'/upload/banner/'.$model->BLOB;
$img1 = $baseUrl.'/upload/banner/no_images.jpg';
if($img!='' && file_exists(Yii::app()->request->baseUrl.'/upload/banner/').$img) {
echo CHtml::image($img,'',array("height"=>"3 0ox","width"=>"30px"));
}else {
echo CHtml::image($img1,'',array("height"=>"30ox","width"=>"30px"));
}
?>
@Ankit Modi ,Thanks brother
the problem may that i was uploading the images in folder in the protected folder
now it is in a folder in the project root
and i used some of your code and it is working very well
thank you very much
You need to make the ‘UserPhotos’ available to the web. The ‘protected’ directory is NOT accesssable via a browser. I would change the save location to ‘/images/UserPhotos’ then use:
try:
<?php echo CHtml::image(Yii::app()->baseUrl.'/images/UsersPhotos/'.$model->Photo); ?>
else, you could leave the avators in /protected/UsersPhotos, then create an action in the controller to get the avator
public function actionGetAvator($id) {
//find the correct avator from $User->...
//send it as an image file by using the php header() and sendFile() methods.
}
To generate the link something like this:
<?php echo CHtml::link(CHtml::image(array('site/getavator','id'=>$data->id)),...)
If you ever did want to use the Yush extension, you could use this code.
public function actionCreate()
{
$model=new Users;
if(isset($_POST['Users']))
{
$model->attributes=$_POST['Users'];
$UserName=$model->UserName;
$uploadedFile=CUploadedFile::getInstance($model,'Photo');
$fileName = "{$UserName}_{$uploadedFile->getName()}";
$model->Photo = $fileName;
if($model->save())
{
$fullPath = Yush::getPath($model, Yush::SIZE_ORIGINAL, $model->Photo);
$uploadedFile->saveAs($fullPath);
$this->redirect(array('view','id'=>$model->UserID));
}
}
$this->render('create',array(
'model'=>$model,
));
}
// View
<b><?php echo CHtml::encode($model->getAttributeLabel('Photo')); ?>:</b>
<img src="<?php echo Yush::getUrl($model, Yush::SIZE_ORIGINAL, $model->Photo); ?>" alt="image" height="" width=""/>;
Also, you line of code
$fileName = "{$UserName}_{$uploadedFile}";
should probably be
$fileName = "{$UserName}_{$uploadedFile->getName()}";
