[solved] delete file

Yii 1.1 General Discussion

Hi guys,

i have a function to upload new and update images for a profile. What i am looking for now is a function to delete the ‘old’ image, after update or if the user wants to delete his profile image.

I cannot find any function in the api to delete a file…

Do you have any hints for me where to look?

TIA

Marco

Isn’t it a PHP function unlink()?

I tried to delete the files as you suggest using unlink and got following error.


unlink(/Users/monaye/Dropbox/website/umenoki-yii/protected/../images/) [<a href='function.unlink'>function.unlink</a>]: Operation not permitted

This is my actionUpdate




public function actionUpdate($id)

	{

		$model=$this->loadModel($id);


		// Uncomment the following line if AJAX validation is needed

		// $this->performAjaxValidation($model);

		

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

		

		if(isset($_POST['Patients']))

		{

			

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

			if($model->save()) {

				

				$imageName = Patients::model()->find('ID=?',"$model->ID");

				unlink(Yii::app()->basePath."/../images/".$imageName);

				$model->patientPic->saveAs(Yii::app()->basePath."/../images/".$model->patientPic->name);

				$this->redirect(array('view','id'=>$model->ID));

			}

		}


		$this->render('update',array(

			'model'=>$model,

		));

	}

Thank you for the help

Looks like you are trying to delete a directory. Check the $imageName value before unlink and make sure you have write permissions for images directory.

Thank you for the comment. Andy.

I was able to make it work. Code is not pretty, so I myself not really satisfied. Please let me know if you have cleaner and simpler way to achieve this.

Also, I am more of JS guy and get used to Firebug’s console.log to get value of $valuable but not sure hot to do it in yii. I usually just echo out $valuable but not working within actionUpdate function.

Thank you for the help.




public function actionUpdate($id)

	{

		$model=$this->loadModel($id);


		

		if(isset($_POST['Patients']))

		{

				

			// Define image's location

			$imageLocation = Yii::app()->basePath."/../images/";

			

			// query table where ID = currnet ID

			$patientInfo = Patients::model()->find("ID = ".$model->ID);

			

			// if patientPic(image) field in table is not empty

			// delete images  

			if(!empty($patientInfo->patientPic)){

				unlink($imageLocation.$patientInfo->patientPic);

			}

			

			// get fileuploaded info

			$imageInfo = CUploadedFile::getInstance($model,'patientPic');

			

			// replace all space in file name with _  

			$imageName = str_replace(" ","_",$imageName->name);

			

			// Adding yearmonthdate_time to file name

			$imageName = date("Ymd_Gi")."_".$imageName;

			

			// ready to update database with new filename

			$model->patientPic=$imageName;			

			

			if($model->save()) {

				

				// can't use $imageName since it only contain file name

				// saveAs need $imageInfo -> tempName 

				$imageInfo->saveAs($imageLocation.$imageName);

				$this->redirect(array('view','id'=>$model->ID));

			}

		}


		$this->render('update',array(

			'model'=>$model,

		));

	}
