images in database

General PHP

Goog day!

I have some problems with display an images. Images stored in database.

i have method of model-class




	public function imageShow()

	{

		header("Content-type: image/png");

                echo $this->image;

	}

and i use it in views like this:




<?php echo CHtml::image($model->imageShow()); ?>

but my browser give me something like this: Image couldn’t display because of has an error. This error just when i sending a header


 header("Content-type: image/png");

, but without content-type display just binary data of image.

Does anyone know how to display images from database?

I’m sure this won’t work, because CHtml::image() takes the image url as the first parameter but your imageShow() method returns nothing, just sends the binary data to the output.

You should create an action that sends the image and point to that action in CHtml::image() methods first parameter.

So something like this:

Controller




class MyImageController extends CController

{

    ...


    public function actionDisplayImg()

    {

        $model = $this->loadModel();

        Yii::app()->request->sendFile('myimage.png', $model->image, 'image/png');

    }


    ...

}

View




...


<?php CHtml::image($this->createUrl('myImage/displayImg')); ?>
