Backoffice Grid Views often list information like Posts for a blog while showing at the same time linked information like the User who wrote that post. For more efficiency, it is appropriate that the User is displayed as a link to the User detail page.
CDataColumns allow adding a link by modifying the 'value' property for the column, whicle CLinkColumns are built to create columns with links, but not really associated to data.
In order to make the addition of links as easy as this:
$this->widget('zii.widgets.grid.CGridView', array( [...other gridview options...], 'columns'=>array( array( 'name'=>'username', 'urlExpression'=>'array("admin/devices/view","id"=>$data->user_id)', 'class'=>'YDataLinkColumn', ), ) ));
, I created the following class (already referenced in the example above):
Another relevant extension
I didn't see pclinkbutton before - it adds the imageUrlExpression function.
You are the author so you noticed the ressemblance.
What I prefer in my proposal is that it is easy to move from a CDataColumn (which is the default class) to YDataLinkColumn (without the need to change to labelExpression) and that CDataColumn is overloaded rather than copied.
Anyway, the idea is to share thoughts ;-).
thanks for code share :)
Using CLinkColumn to do this
This is cool here is how I did it using CLinkColumn....
Why not CLinkColumn?
Just saw St Clair's post and wondered why I did not use CLinkColumn just like that.
As far as I can see (in a short glimpse), I conclude that CLinkColumn does not provide filtering functionnality on the data while CDataColumn does.
So if you want to sort the data represented in the links, CLinkColumn alone will not do the job.
