Example - AJAX Forms

Here we have the same simple contact form, but this time with an AJAX submission.

Feel free to submit the form as often as you want. The form is saved to your session, but the data is not saved or logged anywhere else. All it does is validate the inputs and return a success or error message. The session data facilitates persistence of some inputs, so you only need to enter your name and email once. You can also see your most recent form submission presented using Form Reform Display.

Submit

Submit processing is handled by the same pipeline used in Getting Started - Your First Form.  The only difference is that it is AJAX. Rather than rendering a complete new page after the form submission, just the form data is sent to the server and the form results are returned into the page.

The pipeline shown below is a front-end non-editable version of the pipeline used to handle the above form. You can expand any stages to view the details. The submitted form is only saved to your session.

The Condition If section towards the end of our pipeline is to add a display of any UTM tags, as described in Example - Tracking UTM tags. If you are not using Form Reform UTM, you can ignore that part of the pipeline.

Handler pipeline for: Submit

Handlers in the pipeline will be applied in sequence when a form is submitted.

Spam Detect

Configure multiple spam detection strategies. Each spam detection strategy can be separately enabled to either fail silently or to provide an error message that can then be managed through the On Error handlder.
Check for spam using the core Anti-Spam service.
Check using the core Banned Words service. Use this with caution on multilingual sites. A banned word in one language could be perfectly acceptable in another language.
Check using the core IP Deny list. The IP Deny service maintains a dynamic blacklist and whitelist of IP addresses. If an IP address is not in the whitelist it is checked against the blacklist.
Check if the submission contains URLs. URL inputs are exempt from this check.
Check if the submission contains <html> tags. Rich Text inputs are exempt from this check.
Check if the submission contains <script> tags. This should normally be enabled.
Some blocks such as the Honeypot and Captcha also detect spam. Their detection response can be managed by the normal form validation error handling , or by direct integration with this Spam Detect handler.

Validate Input Fields

Validate form input fields. Validate the form input fields provided by each block in the form. Provides a list of errors as {{errors:list}} if validation fails.

On Success

Denotes success processing (no errors). On Error and On Success should always be used in together to denote processing for errors and processing for no errors. Either may be used first.

Save to Session

Save form submission to session data. Data extracted from form fields is saved to the visitor/user session data. This is transient data that lasts for the duration of the Concrete CMS session. The primary reason for saving to a session is to enable values to be recovered and inserted into the same or other forms.
A form can be saved to the name configured by the form blocks or to a different (alias) name. This can be convenient when you take advantage of the default name "form_reform" when adding a single form to a page, but would like a more specific name for the saved form data.
A form submission may optionally update an existing response by matching one or more criteria of the response.
When a user is completing multiple forms, to keep the data from growing, old submissions may be cleared.
Name
Form items may optionally be redacted from the data that is saved. For example, to remove a password from the saved data. Redacted items are listed by input_name.
Where suggestions are offered, these are only suggestions. Other input names/handles may exist in the form and may be entered.

Message

Create a form response message to be displayed to the user. Build boilerplate for a response message, fill the boilerplate with form and site parameters and select a level to emphasize the message display. All text fields can use {{place_holders}} to be filled with system or entered form values.
The level of a message will also affect the Hide/Do-not-render state of subsequent form controls
   

Comment

Insert a comment. Make a comment or note within the pipeline. This handler has no effect on pipeline processing.
The condition below is purely for demonstrating UTM tags. If you don't use UTM, you can ignore this condition.

Condition If

Check a condition and either proceed or move forwards to an alternative. The handlers ConditionIf, ConditionElseIf, ConditionElse and ConditionEnd manage a single level of conditional processing in form handling.
     
     
     
     

Message

Create a form response message to be displayed to the user. Build boilerplate for a response message, fill the boilerplate with form and site parameters and select a level to emphasize the message display. All text fields can use {{place_holders}} to be filled with system or entered form values.
The level of a message will also affect the Hide/Do-not-render state of subsequent form controls
   

Condition End

Denotes end of condition processing. The handlers ConditionIf, ConditionElseIf, ConditionElse and ConditionEnd manage a single level of conditional processing in form handling.

On Error

Denotes error processing. On Error and On Success should always be used in together to denote processing for errors and processing for no errors. Either may be used first.

Message

Create a form response message to be displayed to the user. Build boilerplate for a response message, fill the boilerplate with form and site parameters and select a level to emphasize the message display. All text fields can use {{place_holders}} to be filled with system or entered form values.
The level of a message will also affect the Hide/Do-not-render state of subsequent form controls
   

After Submit

All the blocks in this example form, except for the Message block, are configured to be Hide When a success message is shown. The original Do not render isn't relevant to an AJAX form and could actually prevent a multi-step AJAX form from working. If you forget to change that, Form Reform applies the associated ..Hide When.. class whenever Do not render is checked, buit that won't save you in every case.

New form states returned with the form results are applied to the page and form components configured with ..Hide When.. adapt to the new states accordingly.

An AJAX form can even have a redirect, though that is not recommended. If a completed form needs to redirect it makes more sense to just submit the form it the normal way.

In Edit Mode

In edit mode, the blocks for the form are identical to those in Getting Started - Your first form. The only changes necessary for this simple form are to set the submit to AJAX in the options tab of the Submit block and to change the Do Not Render flags to Hide When.

However, we didn't stop there. We have also added a spinner block and configured it to overlay the form while it submits.

Developer Analysis

Additional Pages

Reform the way you add new input controls

If you need a specialized template or a custom input element, you can design new templates  or new block types for form elements as you would any block type.

Blocks are easy for third party addition or extension. Block templates and are the first thing any Concrete CMS developer learns to code. They are one of the easiest things to code. The underlying mechanisms are well established and reliable.

Reform what you can do with form data

Form handlers are built about the same extensible plugin system as many of my other addons (Universal Content Puller, Omni Gallery, Extreme Clean ...).

The whole system is aimed at easy extension within Form Reform, by third party addons, by agencies and by site building developers.

Handlers can be easily added to do whatever you want with the form data.

Reform where you can save form data

Saving form data with Form Reform is simply a handler in the processing pipeline. You can save to multiple locations or just one location.

If you need to save data elsewhere, such as to a dedicated table, a table provided through another addon, to another database, send it to an API, forward it to another server, or anywhere you can imagine, you can adapt or develop a form handler to do so.

The complexity of the code depends on where you are saving or sending the data, but wrapping that into a form handler plugin for Form Reform is straight forward.

The Form Reform handler plugin system is designed for easy extension.

Learn with a simple form

While you may have plans to implement some much more complex forms using Form Reform, we strongly recommend you start with a simple form such as our contact form example in order to review the basic principles of using Form Reform before you move onto anything bigger.

  1. Start by submitting the form at Getting Started - Your First Form a few times, even making some deliberate mistakes.
  2. Watch our Getting Started with Form Reform video to see how the form is built.
  3. Read through the rest of Getting Started - Your First Form for more details of how this form is built.
  4. Create a test page on your site to build your own version of Getting Started - Your First Form and experiment.
  5. Develop your test page with some of the concepts introduced by our further examples and experiment with some of the other form inputs.
