<?= $this->Form->create($contact); ?>
<?= $this->Form->input('name'); ?>
<?= $this->Form->input('email'); ?>
<?= $this->Form->input('body'); ?>
<?= $this->Form->button('Submit'); ?>

<?php
// In a controller
namespace App\Controller;

use App\Controller\AppController;
use App\Form\ContactForm;

class ContactController extends AppController
{
public function index()
{
$contact = new ContactForm();
if ($this->request->is('post')) {
if ($contact->execute($this->request->data)) {
$this->Flash->success('Your message has been sent; we\'ll get back to you soon!');
$this->request->data['name'] = null;
$this->request->data['email'] = null;
$this->request->data['body'] = null;
} else {
$this->Flash->error('There was a problem submitting your form.');
}

return $schema->addField('name', 'string')
->addField('email', ['type' => 'string'])
->addField('body', ['type' => 'text']);
}

protected function _buildValidator(Validator $validator)
{
return $validator->add('name', 'length', [
'rule' => ['minLength', 10],
'message' => 'Please enter your name'
])->add('email', 'format', [
'rule' => 'email',
'message' => 'Please enter a valid email address',
])->add('body', 'length', [
'rule' => ['minLength', 25],

You can fixed it by moving the contact template form into the element so that it will be available in any pages.

inside element in the contact folder, form below must be present

<legend><?= __('Our Form') ?></legend>
    <fieldset>
        <?php
        echo $this->Form->input('name');
        echo $this->Form->input('email');
        echo $this->Form->input('body');
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end(); ?>

then in your pages

you can just call

<?php 
   echo $this->element('contact/index');
 ?> 

assuming you created index.ctp inside contact folder in element

Hope it solved your problem.
