Radical Form

Free v4.2.6 J5–J6 22 83

A free Joomla system plugin that turns plain HTML markup into AJAX feedback forms: email, file uploads, submission history, CAPTCHA-free antispam, Telegram, MAX, JivoSite and Verbox.

RadicalForm keeps the look of a form separate from its processing. The site developer writes the markup and styling — in a template, a module, a page builder or an online store product page — and the plugin adds AJAX submission, a CSRF token, validation, file uploads, notifications, history and antispam. It does not impose a CSS framework and does not need jQuery. This suits forms in modal windows, one-click order buttons and landing pages where several forms on one page should look different.

Features

  • AJAX submission with no limit on the number of forms per page.
  • Works in modal windows, with the option to close the window after submission.
  • HTML5 validation, required fields, checkbox and multi-select fields.
  • Per-form recipients, a custom email subject that can include any field, Reply-To, CC and BCC copies, and individual settings via rfTarget.
  • Multiple file upload fields, storage control and attaching files to the email.
  • History of regular and blocked submissions, with CSV export.
  • Collection of allowed UTM tags, sent along with the form.
  • Yandex Metrica goals set in the plugin interface.
  • Antispam by timing, IP and content, a JavaScript browser check and limits on mass submissions, with no CAPTCHA.
  • Integrations: Telegram, MAX, JivoSite, Verbox. Leads can be sent to amoCRM and Bitrix24 with the separate WT AmoCRM - RadicalForm and WT JoomShopping Bitrix24 PRO plugins.
  • Email template overrides, custom PHP layouts and plugins of the radicalform group.
  • Works correctly with Joomla caching and multilingual sites, with a separate form per language.

Creating a form

  1. Place an ordinary HTML form wherever it is needed. The recommended container is a <form> tag; if the environment already outputs an outer <form>, use <div class="rf-form"> instead, since forms cannot be nested.
  2. Give the submit button the rf-button-send class, with type="button" inside a <form>.
  3. Give every field to be sent a name attribute; fields without one are ignored. The action and method attributes are not needed.
  4. Mark required fields with the required class or the standard HTML5 attributes required, type and pattern.

A field's label in the email and history comes from its name. To translate it, create a Joomla language override: for name="phone", a PHONE constant. Reserved Joomla names (option, plugin, group, format, module, template, method) cannot be used.

Setup after installation

  1. For email, keep the Send email option enabled and enter the main address, plus CC, BCC, Reply-To and alternative recipients if needed.
  2. Check the CSS classes for invalid fields and upload errors; the defaults suit Bootstrap and UIkit.
  3. Check JavaScript #2, which runs after a successful submission and by default shows the message with Joomla.renderMessages().
  4. Enable only the integrations, file uploads, UTM tags and antispam mechanisms that are needed.

Basic HTML knowledge is required to work with the plugin.
