This plugin is intended for web developers who need to create many forms and keep them under full control.
With that plugin you can create any form for your Wordpress website.
You can create a class of your form, including the following methods:
- init - method which will always be called if exists;
- set_form - method for creating form's array;
- get_values - method for getting values from DB;
- update - method which updates data sent in the request.
You can put your class in the "oi-forms" folder, previously created in the active theme or create standalone plugin that will call your class.
Code of example form class:
namespace MyNameSpace;
class MyForm extends forms {
private $user_id = 0;
private $post_id = 0;
/**
* Initialization

* @param $request

protected function init( $request ) {
// if user is not authorized or has not enough privileges
if ( ! is_user_logged_in() || ! isRole( 'contributor' ) ) {
$this->error = __( 'You have to be authorized.', __NAMESPACE__ );
}
else {
$this->user_id = ! empty( $_GET['user_id'] ) ? $_GET['user_id'] : 0;
if ( ! empty( $request['ID'] ) ) {
$this->post_id = $request['ID'];
}
else {
$this->post_id = ! empty( $_GET['post_id'] ) ? $_GET['post_id'] : 0;
}
// getting values from DB
$this->values = $this->get_values( $request );
// convert list of tags to PHP 5 style
$this->allowedContentTags = join( '', array_map( function ( $tag ) {
return "<{$tag}>";
}, $this->allowedContentTags ) );

To call your form on any page or in a template you have to write a shortcode.
Form id in a shortcode should be separated with a - symbol instead of slash.
Shortcode example:
[form form_id="MyNameSpace-MyForm"]
If you want to use standalone plugin for your form you can do it like that:
Plugin main file example
/**
* Plugin Name: My Form Plugin
* Plugin URI: https://sh14.ru/
* Description: Post submit form.
* Author: John Dou
* Version: 1.0
*/
Namespace MyNameSpace;
function isFormsExists() {
if ( class_exists( 'forms\forms' ) ) {
require 'PostForm.php';
}
}
add_action( 'plugins_loaded', __NAMESPACE__ . '\isFormsExists' );
Just form array example
$form = [
[
'type' => 'Form',
'content' => [
[
'type' => 'Select',
'attributes' => [
'super' => '',
'user-attr' => 'aaa',
'required' => '',
'name' => 'categories[]',
'data' => [
'post' => 15,
'check' => true,
'name' => 'small caption',
'inside' => [
'one' => 1,
'two' => 2,
],
],
'asd' => 'zxc vbn mkj',
'class' => [
'form-control',
'light',
],
'style' => [
'color' => 'red',
'border' => [
'width' => [
'top' => '1px',
'right' => '2px',
'bottom' => '3px',
'left' => '4px',
],
'style' => 'solid',
'color' => 'black',
],
],
],
'content' => [
[
'type' => 'Option',
'content' => 'News',
'attributes' => [
'value' => 3,
'selected' => true,
],
],
[
'type' => 'Option',
'content' => 'Interview',
'attributes' => [
'value' => 7,
],
],
],
'vars' => [
'label' => 'Select category',
],
'html' => '<div class="form-group">'
. '<label for="%id%" class="form-group__label">%label%</label>'
. '<div class="form-group__input">%%</div>'
. '</div>',
],
[
'type' => 'input',
'attributes'=>[
'name' => 'categories[]',
'value' => 'text 4',
],
'html' => '<div class="form__control">%%</div>',
],
],
'html' => '<div class="form">%%</div>',
],
];
print_r( Element::get( $form ) );
To add your own endpoints you can write a filter function:
/**
* Forms endpoint filters
*
* @param $endpoints
*
* @return array
*/
function forms_endpoints( $endpoints ) {
// endpoint for working with
return array_merge( $endpoints, [
// publication form
'form' => [
'methods' => [ WP_REST_Server::READABLE, WP_REST_Server::CREATABLE ],
],
] );
}
add_filter( 'forms_endpoints_filter', __NAMESPACE__ . '\\' . 'forms_endpoints', 10, 1 );
GET: /wp-json/forms/form/?request=get&response=vue&form_id=<form id like in shortcode>
params:
'request' => 'get'- determine which property or method should be returned'response'=> 'json'- response format: html/vue/json
POST: /wp-json/forms/form
params:
'request' => 'update'- determine which property or method should be returned
You can check for transfer method and if it not an ajax or api the the data has been sent via usual method with page reloading
if(empty($_POST['transfer_method'])){
wp_redirect('?post_id' . $data['ID'] );
}else{
return $data;
}
