See 🐛 $form_state->setErrorByName() breaks $form_state->set() Active .
Extremely simplified example in the code below.
$form_state->set('display_correct_cnum', TRUE);
$form_state->setErrorByName('input', 'error');
$form_state->setRebuild();
For some reason, the setErrorByName seems to prevent the previous set to work.
When I comment out that line, the set does work properly.
<?php
namespace Drupal\xxx\Form;
use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormStateInterface;
class TestForm extends FormBase {
public function getFormId() {
return 'testform';
}
public function buildForm(array $form, FormStateInterface $form_state) {
$form['customer'] = [
'#type' => 'container',
'#attributes' => [
'id' => ['company-fieldset'],
],
];
$form['customer']['input'] = [
'#type' => 'textfield',
'#title' => 'input',
];
$form['customer']['searchVAT'] = [
'#type' => 'submit',
'#value' => $this->t('Search'),
'#name' => 'searchVAT',
'#validate' => ['::validateVAT'],
'#submit' => ['::searchVAT'],
'#ajax' => [
'callback' => '::searchVATCallback',
'wrapper' => 'company-fieldset',
],
];
$displayCheckbox = $form_state->get('display_correct_cnum');
ksm($displayCheckbox);
return $form;
} // End of buildForm
/**
* Called when the search button for company number is clicked.
*
* Validates the VAT number before the submit handler is called.
*/
public function validateVAT(array &$form, FormStateInterface $form_state) {
$form_state->set('display_correct_cnum', TRUE);
// commenting out the line below makes the above line work
$form_state->setErrorByName('input', 'error');
$form_state->setRebuild();
}
public function searchVAT(array &$form, FormStateInterface $form_state) {
}
public function searchVATCallback(array &$form, FormStateInterface $form_state) {
return $form['customer'];
}
public function validateForm(array &$form, FormStateInterface $form_state) {
}
public function submitForm(array &$form, FormStateInterface $form_state) {
}
}
