We will be creating a custom module in Drupal 9 to build a custom form & store the data in a custom content type.
Step 1: Name of the Module
We need to create a custom module under 'modules/custom' folder. We will name the folder as 'candidates'
Step 2: Creating the info.yml file
We have to create a yaml file with the machine name of our module for Drupal to be able recognize the module. We will name the file as 'candidates.info.yml'
name: Candidates Data type: module description: A custom module to enter candidate details package: Custom version: 1.0 core_version_requirement: ^8 || ^9 Step 3: Creating the routing.yml file
Next step is to add a candidates.routing.yml file under the 'candidates' directory.
Under path, we specify the URL path for adding Candidate data.
Under defaults, the _controller which references a method on the CandidatesController class and the _title specifies the default page title.
Under requirements, we specify the permission to view the page.
candidates.form: path: '/add-candidate' defaults: _title: 'Add Candidates' _form: '\Drupal\candidates\Form\CandidatesForm' requirements: _permission: 'access content' Step 4: Adding the controller
We will create a controller file named 'CandidatesController.php' under 'modules/custom/candidates/src/Controller'. In this file, we will create a custom form to validate & submit candidate data. We will store the data into a custom content type named 'candidate'.
<?php /** * @file * Contains \Drupal\candidates\Form\CandidatesForm. */ namespace Drupal\candidates\Form; use Drupal\Core\Form\FormBase; use Drupal\Core\Form\FormStateInterface; use Drupal\node\Entity\Node; class CandidatesForm extends FormBase { /** * {@inheritdoc} */ public function getFormId() { return 'candidates_form'; } /** * {@inheritdoc} */ public function buildForm(array $form, FormStateInterface $form_state) { $form['candidate_name'] = array( '#type' => 'textfield', '#title' => t('Candidate Name'), '#required' => TRUE, ); $form['candidate_dob'] = array( '#type' => 'date', '#title' => t('Birth Date'), '#required' => TRUE, ); $form['candidate_gender'] = array( '#type' => 'select', '#title' => ('Gender'), '#required' => TRUE, '#options' => array( 'male' => t('Male'), 'female' => t('Female'), 'other' => t('Other'), ), ); $form['candidate_mobile'] = array( '#type' => 'textfield', '#title' => t('Mobile'), '#required' => TRUE, '#maxlength' => 10, ); $form['candidate_email'] = array( '#type' => 'email', '#title' => t('Email-ID'), '#required' => TRUE, ); $form['candidate_city'] = array( '#type' => 'textfield', '#title' => t('City'), '#required' => TRUE, ); $form['candidate_country'] = array( '#type' => 'textfield', '#title' => t('Country'), '#required' => TRUE, ); $form['candidate_description'] = array( '#type' => 'textarea', '#title' => t('Description'), '#required' => TRUE, ); $form['actions']['#type'] = 'actions'; $form['actions']['submit'] = array( '#type' => 'submit', '#value' => $this->t('Save Candidate Data'), '#button_type' => 'primary', ); return $form; } /** * {@inheritdoc} */ public function validateForm(array &$form, FormStateInterface $form_state) { if ($form_state->getValue('candidate_name') == '') { $form_state->setErrorByName('candidate_name', $this->t('Please Enter Name')); } if ($form_state->getValue('candidate_dob') == '') { $form_state->setErrorByName('candidate_dob', $this->t('Please Enter Birth Date')); } if ($form_state->getValue('candidate_gender') == '') { $form_state->setErrorByName('candidate_gender', $this->t('Please Select Gender')); } if ($form_state->getValue('candidate_mobile') == '') { $form_state->setErrorByName('candidate_mobile', $this->t('Please Enter Mobile')); } if ($form_state->getValue('candidate_email') == '') { $form_state->setErrorByName('candidate_email', $this->t('Please Enter Email-ID')); } if ($form_state->getValue('candidate_city') == '') { $form_state->setErrorByName('candidate_city', $this->t('Please Enter City')); } if ($form_state->getValue('candidate_country') == '') { $form_state->setErrorByName('candidate_country', $this->t('Please Enter Country')); } if ($form_state->getValue('candidate_description') == '') { $form_state->setErrorByName('candidate_description', $this->t('Please Enter Description')); } } /** * {@inheritdoc} */ public function submitForm(array &$form, FormStateInterface $form_state) { $node = Node::create(['type' => 'candidate']); $node->langcode = "en"; $node->uid = 1; $node->promote = 0; $node->sticky = 0; $node->title= $form_state->getValue('candidate_name'); $node->field_birth_date = $form_state->getValue('candidate_dob'); $node->field_gender = $form_state->getValue('candidate_gender'); $node->field_mobile = $form_state->getValue('candidate_mobile'); $node->field_email_id = $form_state->getValue('candidate_email'); $node->field_city = $form_state->getValue('candidate_city'); $node->field_country = $form_state->getValue('candidate_country'); $node->field_description = $form_state->getValue('candidate_description'); $node->save(); \Drupal::messenger()->addMessage(t("Candidate Data Save Successful")); } } Step 5: Creating custom content type
Create a custom content type named 'candidate' to store the data
