Display a key from unserialized data field I really don't understand how the "User: Data" field works. Couldn't find any documentation of this.

I want to set the Display format to "A certain key" to output the identifier value from this serialized data (relevant snippet):

a:1:{s:10:"hybridauth";a:26:{s:10:"identifier";s:17:"76561198181833179";


When I enter identifier as key, I only get this notice and no output.


  Notice: Undefined index: identifier in views_handler_field_serialized->render() (line 60 of www/htdocs/****/sites/all/modules/views/handlers/views_handler_field_serialized.inc).


What do I have to enter in the "Which key should be displayed" field exactly, to display the identifier value?
You need to add an Global PHP field and put the following code in output value to get the identifier field value.

&lt;?php 
 $result = unserialize($row-&gt;data); 
 print $result['identifier'];
?&gt;


Note : You should exclude Data field from display.

Since you very cautious in not using PHP, did you try the following option, change the ckeditor_skin to identifier. But it will produce the output as 76561198181833179['identifier'].
