Hi,

I've got the below code. After enabling the module, the field is seen disabled in /admin/config/people/accounts/display/full. Furthermore, even if I enable it, it is not on user account page, even though it is visible in dpm() output. This started happening after I changed the field name.

<?php
/**
* Implements hook_install().
*/
function tckn_kontrol_install() {
$field = array(
'field_name' => 'field_tckn',
'type' => 'text',
'settings' => array(
'max_length' => 11,
),
);
$instance = array(
'field_name' => 'field_tckn',
'entity_type' => 'user',
'bundle' => 'user',
'required' => TRUE,
'label' => t('TCKN'),
'description' => t('Enter your TCKN.'),
'settings' => array(
'user_register_form' => TRUE,
),
'display' => array(
'default' => array(
'label' => 'above',
'type' => 'text_textfield',
),
),
'widget' => array(
'settings' => array(
'size' => 12,
),
),
);
field_create_field($field);
field_create_instance($instance);
}
function tckn_kontrol_uninstall() {
$instance = array(
'field_name' => 'field_tckn',
'bundle' => 'user',
);
field_delete_field($instance['field_name']);
}
