If you manage an academic journal on OJS, you already know the problem: a new author registers, submits a manuscript — and then you realize their ORCID iD and phone number are missing from their profile. You send an email asking them to update their profile, wait for a response, and sometimes follow up again. This small gap in the registration workflow costs time for everyone involved.

Registration Fields is an open-source OJS plugin that closes this gap by adding ORCID iD and Phone Number fields directly to the user registration form.

The Problem

OJS stores both ORCID iD and phone number in user profiles. These fields exist in the system and are used by DOI registration, Crossref deposits, and editorial communication. However, OJS only allows users to fill in these fields after registration, through the profile editor. There is no built-in way to ask for this information during signup.

For journals that require ORCID iDs — an increasingly common policy — this creates an unnecessary extra step. Authors register, then must be reminded to go back and add their ORCID. For editorial offices that need phone numbers for communication, the same problem applies.

What the Plugin Does

The Registration Fields plugin adds two optional fields to the OJS registration form, positioned between the profile section and the login credentials section:

ORCID iD and Phone Number fields appear on the registration form, above the Login section.

Each field can be independently enabled or disabled, and each can be set as required or optional. The configuration is done through a simple settings panel accessible from the plugin management page:

The settings panel lets you enable, require, or disable each field independently. A debug mode is available for troubleshooting.

Values entered during registration are saved directly to the corresponding OJS profile fields — the same fields used by ORCID integrations, Crossref, and the editorial contact system. No new database tables are created; the plugin simply writes to what is already there.

Key Features

ORCID iD validation accepts three common input formats — bare identifier (0000-0000-0000-0000), full HTTPS URL, or HTTP URL — and normalizes all of them to the standard https://orcid.org/ format on save.

Phone number validation accepts international formats with country codes, supporting digits, spaces, plus signs, dashes, and parentheses.

Theme compatibility is handled through flexible pattern matching with a built-in fallback mechanism. The plugin works across OJS themes including Default, Manuscript, Bootstrap3, Health Sciences, JournalPlus, NIVO, and AXIS. If a theme uses an unusual HTML structure, the fields are still rendered before the form’s closing tag.

Debug mode can be enabled from the settings panel to write diagnostic information to the PHP error log. This helps identify exactly how the plugin is interacting with a particular theme, making it easy to troubleshoot without modifying any code.

Who Is This For?

• Journals requiring ORCID iDs at submission — Collect them upfront instead of chasing authors after registration.
• Editorial offices that communicate by phone — Have the number from day one.
• Journal managers who want cleaner author profiles — Reduce incomplete registrations without adding manual follow-up steps.

Technical Details

The plugin integrates with OJS through its hook system — no core files are modified. It uses output filtering to inject fields into the registration form, server-side validation for all inputs, and a deferred save mechanism to ensure data is written after the user record is created. All input is sanitized and escaped, and the plugin includes CSRF protection for its settings form.

It is compatible with OJS 3.3.0.0 through 3.3.0.22 and PHP 7.4 through 8.2.

Installation
