It’s just the link text. You can do this:


<? echo CHtml::link("Click here to view image",array('displaySavedImage','id'=>$model->primaryKey)); ?>

Note that you have to implement the actionDisplaySavedImage method into your controller. It’s in the wiki as well.

Please take a look at the class references if you not understand a code: CHtml::link

This code displays a link with the ‘my_link_name’ as text to show the image:




  echo CHtml::link('Show the image',array('displaySavedImage','id'=>$model->primaryKey));

If you want to see the image immediatly you can add following code:


  

  $imageUrl = $this->createUrl('displaysavedimage',array('id'=>$model->primaryKey));

  echo CHtml::image($imageUrl);

Hi Joblo,

If you want to see the image immediatly you can add following code:


  $imageUrl = $this->createUrl('displaysavedimage',array('id'=>$model->primaryKey));

  echo CHtml::image($imageUrl);

i put this code inside controller or view side??

thank…

This code is in the view.

In a controller action normally no output (echo, CHtml::XX …) should be generated.
