I have baked this standard add class which works fine.
class ClientsController extends AppController
{
/**
* Add method
*
* @return \Cake\Network\Response|void Redirects on successful add, renders view otherwise.
*/
public function add()
{
$client = $this->Clients->newEntity();
if ($this->request->is('post')) {
$client = $this->Clients->patchEntity($client, $this->request->data);
if ($this->Clients->save($client)) {
$this->Flash->success(__('The client has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The client could not be saved. Please, try again.'));
}
}
$this->set(compact('client'));
$this->set('_serialize', ['client']);
}
With this add.ctp file - the output is as it should be:
<div class="clients form large-9 medium-8 columns content">
<?= $this->Form->create($client) ?>
<fieldset>
<legend><?= __('Register Customer') ?></legend>
<?php
echo $this->Form->input('company_indicator');
echo $this->Form->input('name');
echo $this->Form->input('name2');
echo $this->Form->input('address_id');
echo $this->Form->input('address_street');
echo $this->Form->input('address_street_number');
echo $this->Form->input('address_postal_code');
echo $this->Form->input('address_city');
echo $this->Form->input('address_country');
echo $this->Form->input('address_lat');
echo $this->Form->input('address_lng');
echo $this->Form->input('phone1');
echo $this->Form->input('phone2');
echo $this->Form->input('fax');
echo $this->Form->input('website');
echo $this->Form->input('logo');
echo $this->Form->input('vat_number');
echo $this->Form->input('taxId');
echo $this->Form->input('tax_office');
?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>
</div>
I try to do the same with wizard steps

The error details
==> Invalid data type, must be an array or \ArrayAccess instance. ==> InvalidArgumentException
⟩ Cake\View\Helper\FormHelper->input APP/Template\Clients\reg_step1.ctp, line 9 which corresponds to this line echo $this->Form->input('company_indicator');
I tried the same with commenting this line but i get the same error.
I checked the $client which is empty in both examples. (YES $client is an Entity)
I searched for this error but found only HASH errors which have nothing to do with this case. There must be an error in the controller but i could not find it. Why is this error raised in this context? Where do i have to search to find the real issue? Any ideas?
