I'm new to Drupal but have been given the task of creating a widget.
The module loads, fields are displayed, but when I create some content the form values are not being stored when the content is being saved.
.install file:
function cloudinary_field_schema($field) {
$columns = array(
'publicID' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
'url' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
'caption' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
'alt' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
'credit' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE)
);
return array(
'columns' => $columns,
'indexes' => array(),
);
}
.module file:
/**
* Implements hook_field_info().
* define the field type
*/
function cloudinary_field_info() {
return array(
'cloudinary' => array(
'label' => t('Cloudinary image selector'),

Answer 1

You need to implement hook_field_schema in your .install file.
// Something like this
function cloudinary_field_schema($field) {
// $field['type']
return array(
'columns' => array(
'column_name' => array(
'type' => 'float',
'size' => 'big',
'not null' => TRUE,
'default' => 0,
),
)
);
}

It was a logic problem in cloudinary_field_is_empty(). It was always returning false. All working fine now! Thanks for your help Zolyboy!
