here view file.

'photograph', 'id' => 'photograph', 'placeholder' => 'upload user photo', 'maxlength' => '250' ); echo form_upload($input_field_attributes); ?>

and yes used multipart

echo form_open_multipart('user_management/manage_users',array('id' => 'insert_user')); 

so can tell me why getting below error in firebug? , how solve it??

i'm not familiar ci, can see $this->upload->data(); returning array , that's why it's throwing error.

if using php 5.4 try using $this->upload->data()['file_name'] or $this->upload->data()['full_path'] , if using php 5.3 or lower, assign $this->upload->data() variable , access values via proper keys.

just before inserting var_dump($this->upload->data()); , i'm sure you'll figure out.
