Report Field

Report invalid fields on the site. For example, a field that displays an e-mail address or telephone number has a wrong address/number. This module allows users to report that field as invalid. If a registered user reports a field, it will be automatically marked as invalid, displaying the text entered in configuration the form. For anonymous users, an e-mail with a confirmation link will be sent.
Important: The module works with fields attached to nodes!

Similar modules:
Flag (https://www.drupal.org/project/flag). Differences: With a flag module, a user can report content at the node level. With report_field module a content can be reported at a field level.

Installation and usage:
1. Ensure JavaScript is enabled.
2. Put the "report_field" module folder in the "modules" folder ("sites/all/modules" for D7 version).
3. Go to "admin/modules" and enable "Report Field" module.
4. After enabling the module, the configuration page will be available (admin/config/content/report_field).
5. First tab, FIELD LIST, displays all fields for each content type available on site. By clicking checkbox next to field name, report field will be available next to that field. Fill in 'Label' and 'Reported' textboxes and optionally check the 'Message' field checkbox. The 'Label' field defines the text displayed next to checkbox rendered below the field. 'Reported' field defines text that is displayed after the field is reported. Finally if checked, the 'Message' field will allow the user to enter some comment when reporting an invalid field.
6. The second tab, REPORTED FIELDS, lists all fields that are reported by users, both by anonymous and registered once.
7. The third tab, ADDITIONAL SETTINGS, allows users to enter the number of days after which all pending requests will be deleted (the default value is 7 days).
