Nomad Forms

A WordPress PHP Composer Package that provides you with an easy way to display and process forms, render and validate fields, and display error/success messages.

Installation

You can install Nomad Forms in your project by using composer.

$ composer require jakesutherland/nomad-forms

Dependencies

Nomad Forms depends on the following packages:

• Nomad Helpers for various functions, constants, and utilities.
• Nomad Validate for validating form submissions and generating error messages.

If for some reason you didn't install Nomad Forms via Composer as a required package in your project, you will still need to run composer install to install it's dependencies as they are not included in the repository.

Documentation

Nomad Forms is a full-featured form generator for processing, validating and displaying forms on your website. You can use Nomad Forms on the front-end or in the admin.

Example Usage

The nomad_form() function is used to get your form configured and set up.

The first parameter is your form ID. In our example below, my_form_id is used as a unique identifer for this form.

The second parameter is your form arguments. This is where you can configure your form and define your form fields.

$my_form = nomad_form( 'my_form_id', array(
	'method'   => 'POST',
	'callback' => 'my_form_callback',
	'fields'   => array(
		// Add your form fields here...
	),
) );

Alternatively, you can use the nomad_fields() function if you want to output just form fields (and still utilize Nomad Forms Theme styles). Basically is a helper function that sets various form arguments to what would be needed in order to just output form fields. See below:

function nomad_fields( $id, $args ) {

	$defaults = array(
		'action'        => null,
		'method'        => null,
		'nonce'         => true,
		'form_tag'      => false,
		'submit_button' => false,
		'reset_button'  => false,
		'cancel_button' => false,
		'callback'      => null,
	);
	$args = wp_parse_args( $args, $defaults );

	return nomad_form( $id, $args );

}

When using this by itself, you would be expected to handle all form processing and validation manually.

Common use case would be adding custom fields to a post type in the WordPress admin and then processing those fields on save_post.

Available Form Arguments

You can customize how a form behaves with many different form arguments available.

Note: The only required form argument is fields. All other form arguments are optional and have defaults set.

action

Type: string

Default: null

Sets the form action if you want the form to be submitted to a specific URL.

This is not recommended unless you plan on handling the form submission yourself. Note that the variable you assign nomad_form() to is only available on the page it is defined, so the other functions likely won't be available somewhere else in your codebase. It is highly recommended that you handle everything on the same page that the form is being displayed on.

allow_modifications

Type: boolean

Default: true

Whether or not you want to allow the potential for other plugins or pieces of code to modify the form.

When set to true, the form can be modified through various hooks, filters and fields added through injections. If set to false, the majority of hooks and filters won't be triggered and form injections will not add any fields.

automate_validation

Type: boolean

Default: true

Whether or not you want to allow automatic validation of form fields.

When set to true, automatically validates values for "choice" type fields (such as button groups, checkboxes, radios, selects, etc) and makes sure that only the options that were available can be used, email fields are valid emails, and numeric fields only contain numbers.

If you already specify any of these rule keys in your field validation, automatic validation will not override them.

callback

Type: callable

Default: null

The function to be called to process the form when it is successful. Must be a valid callback function.

cancel_button

Type: boolean

Default: false

Whether or not to display a "Cancel" button at the bottom of the form.

cancel_href

Type: string

Default: home_url( '/' ); (your WordPress installs homepage)

The URL to go to when the Cancel button is clicked.

cancel_text

Type: string

Default: Cancel

The Cancel button text.

error_message

Type: string

Default: Sorry, there was a problem submitting your form:

When the form is submitted and there is an error, this is the text to be displayed above the list of error messages.

fields

Type: array

Required

The list of form fields to be displayed, submitted validated, and processed.

form_tag

Type: boolean

Default: true

Whether or not the form fields should be rendered inside a <form>...</form> tag. If set to false, the form fields will be rendered inside a <div>...</div> instead.

labels_alignment

Type: string

Default: left

Possible Values: left center right

Determines the text alignment of the field labels.

labels_position

Type: string

Default: top

Possible Values: inline top

Determines where the field labels are displayed in relation to its field.

method

Type: string

Default: POST

Possible Values: POST GET

Determines the form method that is used when the fields are submitted.

nonce

Type: boolean

Default: true

Whether or not to create and use a nomad_form_nonce to make sure that the form being processed is the one that was just submitted.

nonce_message

Type: string

Default: Invalid form submission. Please try again.

The text to be displayed if the nonce verification fails and the form submission was invalid.

reset_button

Type: boolean

Default: false

Whether or not to display a "Reset" button at the bottom of the form.

reset_text

Type: string

Default: Reset

The Reset button text.

submit_button

Type: boolean

Default: true

Whether or not to display a "Submit" button at the bottom of the form.

submit_text

Type: string

Default: Submit

The Submit button text.

success_message

Type: string

Default: Success! Your form has been submitted.

When the form is submitted and there is an error, this is the text to be displayed above the list of error messages.

Each field is defined as a constant in the Nomad_Form_Fields class. Below is a list of all available fields and an example of how it would be registered.
